     BACKGROUND OF THE INVENTION 
     Field of the Art 
     The disclosure relates to the field of contact center technology, and more particularly to the field of cloud-implemented automated callback systems and transitory data management systems. 
     Discussion of the State of the Art 
     Many businesses use groups of service representatives for communicating with clients who initiate communications with the business, such as by telephone calls or text based messaging. To most efficiently use the time and skills of each service representative, the service representatives may be organized into groups based on a skill set. For example, the groupings may be based on the representative&#39;s ability to handle client issues such as the opening of new accounts, billing issues and customer service issues on existing accounts. 
     Typically, if a client calls such a business, voice prompt menu choices enable the calling client to identify the issue for which the client requires service and the client is then queued for a service agent capable of handling the identified issue. As such, it is expected that clients who identify the purpose of their call as a “billing issue” will be queued for, and connected to, a service representative with the ability to handle billing issues. Similarly, it is expected that clients who identify the purpose of their call as a “customer service issue” will be queued for, and connected to, a service representative with the ability to handle customer service issues. 
     There are problems with existing communications systems, such as contact centers, including the following two problems. First, the voice prompt menus that are used to channel callers to the queue for the appropriate group of service agents are exasperating to a client at best. It takes significant time to navigate the layered menus of voice prompts. 
     Second, waiting on-hold while a connection, be it a phone call, web chat, video conference, or other interaction type, is maintained in queue for connection to a service agent is also exasperating to a client at best. 
     In an effort to reduce customer exasperation caused by having to maintain a connection while on-hold in queue, secondary queue systems have been developed. A typical secondary queue system obtains a telephone number at which the calling client can be reached when a service representative is available (i.e., a call back number). The client disconnects, and then, at the proper time, a call back system establishes a connection to the client utilizing the call back number and couples the client to an available representative without waiting on-hold in queue. One exemplary system is disclosed in U.S. Pat. No. 6,563,921 to Williams et al. which is commonly assigned with the present application. 
     While such a system may make the experience of waiting for a connection to a service representative slightly less exasperating, it does not address the inconvenience of having to navigate an irritatingly slow and usually complicated voice prompt menu to enter the queue. 
     Furthermore, when a customer attempts to contact or conduct business with an enterprise, they often have to share information or acquiesce to data requests in order to receive service or perform a transaction. Once a customer provides this information and data, they have minimal agency over what is done with the data once it has been shared. This can be especially worrisome to a customer who provides personal identifying information or financial data. 
     What is needed is a system and method for providing secure storage and management of transitory data that assists customer control over their data when interacting with an enterprise.

     DETAILED DESCRIPTION OF THE DRAWING FIGURES 
     The inventor has conceived, and reduced to practice, a system and method for secure storage and management of transitory data using a blockchain, comprising at least a callback manager, a context analysis engine, a vault manager, and a blockchain manager, which allows a user to create a data container to store data preferences, which encrypts the data stored within a data container, and which stores the encrypted data container in a blockchain. For each block, block reference data may is generated comprising the location of the block and its associated decryption key, and the block reference data is then encrypted with a second encryption key and stored off the blockchain in a separate database. The second key is distributed to involved parties to permit access to and reading of the block reference data. The block reference data is deleted based on self-destruct event triggers or when the involved parties are finished accessing the block reference data. 
     With the proliferation of mobile computing devices clients (e.g., consumers) are increasingly engaging with service agents via text based messaging such as a web chat, text message, email, etc. As is often the case, as few as one or more messages may be exchanged between a client and a service agent before a callback is requested. If a client is messaging with a service agent and the client requests a callback, the callback is generally scheduled with a different service agent other than the agent the client was messaging with. This can lead to a situation where a client, who has already disclosed information regarding the reason for the callback via messages sent to a first service agent, may have to repeat this information again to a second service agent when the scheduled callback occurs. Similarly, a client may be calling a contact center and then navigate voice menus to be routed properly, but the client may end up requesting a callback or otherwise disconnecting from the call. In this situation, any voice menu option selections or responses made by the client prior to a callback request or disconnection may provide useful information about why the client was trying to contact a service agent. 
     When a client makes a first contact (e.g., voice call or text data message) with a contact center, any input (or attributes thereof) provided may be analyzed to determine context content data. Attributes may include, but are not limited to, a username, phone number, device identifier, handle, email, message or call subject, end user, etc. The context content generated or derived from any messages, calls, and attributes may be parsed, compiled, and formatted into a summary report which may be sent to a callback recipient (i.e., service or contact center agent) so that they may have a basic understanding of the client and the clients reason for requesting a callback. This may allow a service agent (or bot or script or some combination) to plan for or proactively address or resolve a callback requestor&#39;s (e.g., client) reason for making the first contact. This may all be facilitated by an embodiment which provides a cloud resident callback and routing platform that receives, via a communication network, data messages and callback requests, which analyzes, schedules, and executes various callback requests, and which generates and routes context summary reports to an appropriate contact center agent computing device. 
     A secure transitory data storage and management system may be used to provide a customer and consumer of a service (e.g., enterprise or company) with improved control over his or her data when interacting with a company, another person, or some other entity. The system may provide a secure vault for the storage of transitory data containers in which system users may choose to store a large plurality of data of various data types. The system may encrypt data that is put inside a container to secure and protect user data. The container owner (e.g., user) may be given a key to access the encrypted container. An individual (person or business entity) may determine at least one or more preference which govern the access and usage of that individuals data stored within a container. The user defined preferences may be used to determine: what subset of user data may be accessible by another party, how the subset of data stored in the container may be accessed and manipulated, when access to the subset of user data is revoked, and who can access the subset of user data stored within the container. The system may store the data container within the vault for as long as the user defined preference allows, at the conclusion of this user-defined time period the data container may be removed (e.g., deleted) from the vault (unless the container owner extends the user-defined time period), resulting in the transitory nature of the data stored within the container. Any party or actor interested in accessing a data container belonging to a given individual must agree to and comply with that individuals user-defined preferences. Upon agreement of the user-defined preferences, the party or actor may be given a key to access the encrypted container. The system may record a detailed audit log in order to track all actors and interactions associated with a given container. In this way the system can provide a transparent history of container and data access which can be used to mediate possible discrepancies in or disputes resulting from the data stored therein. 
     The secure transitory data storage and management system may establish default preferences if a customer does not have any preferences. The system may leverage a context analysis engine, which determines context content data, in order to autonomously generate a default container with default preferences based upon the output of the context analysis engine. For example, a customer may call a mortgage company and leave a voicemail stating that he is interested in applying for a home loan and requests a callback. The cloud callback platform may intercept the voicemail and utilize the context analysis engine to determine the context of the call and the nature of the requested callback. Using the context content data, the vault manager may then automatically create a data container with mortgage application preferences added to the container. Additionally, a profile manager may be used to retrieve customer information which may be used by the vault manager when generating default preferences. The preferences may stipulate what type of data can be added to the container, for example, industry standard mortgage application documents such as proof of income, mortgage history, proof of identification, bank statements and other assets, etc. The default container may comprise fields where the customer financial documentation may be entered. The vault manager may then grant default access to the data container to both the customer who generated the voicemail message and a loan officer working for the mortgage company. The default container may then be sent to the customer allowing the customer to define the container preferences and to add data at the customer&#39;s discretion. According to some embodiments, instead of sending the default container to the customer, an alert (e.g., message) may be sent to the customer which indicates that a default container has been created and along with the alert the access key to that default container, which allows the customer to access and edit the contents of the default container while it is maintained securely in the vault. When a callback is performed between the customer and the loan officer, the default container, which may be identified by the customer&#39;s phone number and the loan officer&#39;s phone number, may be retrieved from the vault and displayed to both parties via a computing device. 
     The blockchain offers protection against the falsification or tampering of data stored within the blockchain. A data object (i.e., data container) cannot be deleted from the blockchain, but all references to it and the keys that decrypt it can be deleted. The system and methods disclosed herein provide a means to stored encrypted data containers on a blockchain while also providing mechanisms for “deleting” transitory data stored in the blockchain by generating block reference data that may be encrypted with a key and the key can be distributed to involved parties (e.g., a callee and callback recipient) which grants access to the block which contains the encrypted data container while also serving as an intermediary that can be deleted, thereby destroying access to the block and effectively destroying the transitory data that is stored in the encrypted data container. 
     One or more different aspects may be described in the present application. Further, for one or more of the aspects described herein, numerous alternative arrangements may be described; it should be appreciated that these are presented for illustrative purposes only and are not limiting of the aspects contained herein or the claims presented herein in any way. One or more of the arrangements may be widely applicable to numerous aspects, as may be readily apparent from the disclosure. In general, arrangements are described in sufficient detail to enable those skilled in the art to practice one or more of the aspects, and it should be appreciated that other arrangements may be utilized and that structural, logical, software, electrical and other changes may be made without departing from the scope of the particular aspects. Particular features of one or more of the aspects described herein may be described with reference to one or more particular aspects or figures that form a part of the present disclosure, and in which are shown, by way of illustration, specific arrangements of one or more of the aspects. It should be appreciated, however, that such features are not limited to usage in the one or more particular aspects or figures with reference to which they are described. The present disclosure is neither a literal description of all arrangements of one or more of the aspects nor a listing of features of one or more of the aspects that must be present in all arrangements. 
     Headings of sections provided in this patent application and the title of this patent application are for convenience only, and are not to be taken as limiting the disclosure in any way. 
     Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more communication means or intermediaries, logical or physical. 
     A description of an aspect with several components in communication with each other does not imply that all such components are required. To the contrary, a variety of optional components may be described to illustrate a wide variety of possible aspects and in order to more fully illustrate one or more aspects. Similarly, although process steps, method steps, algorithms or the like may be described in a sequential order, such processes, methods and algorithms may generally be configured to work in alternate orders, unless specifically stated to the contrary. In other words, any sequence or order of steps that may be described in this patent application does not, in and of itself, indicate a requirement that the steps be performed in that order. The steps of described processes may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to one or more of the aspects, and does not imply that the illustrated process is preferred. Also, steps are generally described once per aspect, but this does not mean they must occur once, or that they may only occur once each time a process, method, or algorithm is carried out or executed. Some steps may be omitted in some aspects or some occurrences, or some steps may be executed more than once in a given aspect or occurrence. 
     When a single device or article is described herein, it will be readily apparent that more than one device or article may be used in place of a single device or article. Similarly, where more than one device or article is described herein, it will be readily apparent that a single device or article may be used in place of the more than one device or article. 
     The functionality or the features of a device may be alternatively embodied by one or more other devices that are not explicitly described as having such functionality or features. Thus, other aspects need not include the device itself. 
     Techniques and mechanisms described or referenced herein will sometimes be described in singular form for clarity. However, it should be appreciated that particular aspects may include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. Process descriptions or blocks in figures should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process. Alternate implementations are included within the scope of various aspects in which, for example, functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art. 
     Definitions 
     “Callback” as used herein refers to an instance of an individual being contacted after their initial contact was unsuccessful. For instance, if a first user calls a second user on a telephone, but the second user does not receive their call for one of numerous reasons including turning off their phone or simply not picking up, the second user may then place a callback to the first user once they realize they missed their call. This callback concept applies equally to many forms of interaction that need not be restricted to telephone calls, for example including (but not limited to) voice calls over a telephone line, video calls over a network connection, or live text-based chat such as web chat or short message service (SMS) texting. While a callback (and various associated components, methods, and operations taught herein) may also be used with an email communication despite the inherently asynchronous nature of email (participants may read and reply to emails at any time, and need not be interacting at the same time or while other participants are online or available), the preferred usage as taught herein refers to synchronous communication (that is, communication where participants are interacting at the same time, as with a phone call or chat conversation). 
     “Callback object” as used herein means a data object representing callback data, such as the identities and call information for a first and second user, the parameters for a callback including what time it shall be performed, and any other relevant data for a callback to be completed based on the data held by the callback object. 
     “Latency period” as used herein refers to the period of time between when a Callback Object is created and the desired Callback is initiated, for example, if a callback object is created and scheduled for a time five hours from the creation of the object, and the callback initiates on-time in five hours, the latency period is equal to the five hours between the callback object creation and the callback initiation. 
     “Brand” as used herein means a possible third-party service or device that may hold a specific identity, such as a specific MAC address, IP address, a username or secret key which can be sent to a cloud callback system for identification, or other manner of identifiable device or service that may connect with the system. Connected systems or services may include a Private Branch Exchange (“PBX”), call router, chat server which may include text or voice chat data, a Customer Relationship Management (“CRM”) server, an Automatic Call Distributor (“ACD”), or a Session Initiation Protocol (“SIP”) server. 
     “Preferences” as used herein mean a set of rules which govern access and interaction with the user data placed inside a data container. The preferences may be used to establish what, how, when, and who rules of the data container. For example, what determine what data or subset of data can be stored in the container, how an enterprise may access the container, when and for how long an enterprise may access the data container, and who (e.g., what enterprise) may access the data container. For example, a customer may create a data container with a time preference of two weeks, which means after two weeks has passed, the data container will be deleted and will subsequently be no longer accessible. 
     Conceptual Architecture 
       FIG.  1    is a block diagram illustrating an exemplary system  100  architecture for a cloud callback platform, according to one embodiment. The system  100  may include at least one cloud callback platform  101 . The cloud callback platform  101  may include at least one callback manager  155 , at least one profile manager  150 , at least one media server  170 , at least one interaction manager  165 , at least one context analysis engine  160 , and at least one context aggregator mechanism  175 . The cloud callback platform  101  may be or include one or more data processing systems, servers, virtual servers, or computing devices. The cloud callback platform  101  may include hardware (e.g., processors of one or more servers), as well as scripts or programs executed by the hardware, and combinations thereof. The cloud callback platform  101  may reside (e.g., physically or logically disposed) in a communication network path between at least one consumer endpoint  110  (e.g., a client or end user or customer computing device) or user brand  130  and at least one enterprise endpoint  120  (e.g., contact center or control computing device, telephone, tablet, cellphone, a switch, etc.). For example, the cloud callback system  101  may communicate (e.g., via a Local Area Network [LAN], Wide-Area Network [WAN], the internet, a cloud environment, or other computer network) with consumer endpoints  110 , enterprise endpoints  120 , and with user brands  130 . 
     According to an embodiment, cloud callback platform  101  may receive requests or data messages  145  via a plurality of communication networks  140  such as public switched telephone network (PSTN), the internet, fixed line (e.g., from the signaling channel of an acoustic modem), wireless network, VoIP, cellular, fiber optic, short message service (SMS) or public or proprietary text messaging networks. These requests may comprise a variety of communication or interaction types, for example including, but not limited to, voice calls over a telephone line, video calls over a network connection, or live text-based chat such as web chat or SMS texting via PTSN or network connection. Such communication networks  140  may be connected to a plurality of consumer endpoints  110 , enterprise endpoints  120 , and user brands  210 , according to the particular architecture of the communication network involved. Exemplary consumer endpoints  110  may include, but are not limited to, traditional telephones, cellular telephones, mobile tablet computing devices, laptop computers, or desktop personal computers (PC). Such devices may be connected to respective communications networks via a variety of means, which may include telephone dialers, VOIP telecommunications services, web browser applications, SMS text messaging services, or other telephony or data communications services. It will be appreciated by one having ordinary skill in the art that such means of communication are exemplary, and many alternative means are possible and becoming possible in the art, any of which may be utilized as an element of system  100  according to an embodiment. 
     Various communication networks such as a PSTN or the Internet, may be further connected to a plurality of enterprise endpoints  120 , which may comprise cellular telephones, telephony switch, desktop environment, internal LAN or WAN, and mobile devices such as tablet computing device. A desktop environment may include both a telephone and a desktop computer, which may be used as a network bridge to connect a telephony switch to an internal LAN or WAN, such that additional mobile devices such as tablet PC may utilize the switch to communicate with PSTN. The telephone may be connected to the switch or it may be connected directly to PSTN. It will be appreciated that the described arrangement is exemplary, and a variety of arrangements that may comprise additional devices known in the art are possible, according to an embodiment. 
     A collection of user brands  130  may be present either singly or in some combination, possibly including a Public Branch Exchange (“PBX”), a Session Initiation Protocol (“SIP”) server, a Customer Relationship Management (“CRM”) server, a call router, or a chat serve, or some combination of these brands. These brands  130  may communicate over a combination of, or only one of, a communication network such as a PSTN, and the Internet, to communicate with other devices including a cloud callback platform  101 , a company phone, or a personal cellular phone. A SIP server is responsible for initiating, maintaining, and terminating sessions of voice, video, and text or other messaging protocols, services, and applications, including handling of PBX phone sessions, CRM server user sessions, and calls forwarded via a call router, all of which may be used by a business to facilitate diverse communications requests from a user or users, reachable by phone over either PSTN or the Internet. A chat server may be responsible for maintaining one or both of text messaging with a user, and automated voice systems involving technologies such as an Automated Call Distributor (“ACD”), forwarding relevant data to a call router and CRM server for further processing, and a SIP server for generating communications sessions not run over the PSTN. Various systems may also be used to monitor their respective interactions (for example, chat session by a chat server or phone calls by an ACD or SIP server), to track agent and resource availability for producing EWT estimations. 
     Cloud callback platform  101  may respond to requests or data messages  145  received from communications networks  140  with callbacks  147  appropriate to the technology utilized by such networks, such as data or Voice over Internet Protocol (VOIP) callbacks sent to Internet, or time-division multiplexing (TDM) such as is commonly used in cellular telephony networks such as the Global System for Mobile Communications (GSM) cellular network commonly used worldwide, or VOIP callbacks to PSTN. Data callbacks may be performed over a variety of Internet-enabled communications technologies, such as via e-mail messages, application pop-ups, or Internet Relay Chat (IRC) conversations, and it will be appreciated by one having ordinary skill in the art that a wide variety of such communications technologies are available and may be utilized according to the invention. VOIP callbacks may be made using either, or both, traditional telephony networks such as PSTN or over VOIP networks such as Internet, due to the flexibility to the technology involved and the design of such networks. It will be appreciated that such callback methods are exemplary, and that callbacks may be tailored to available communications technologies according to an embodiment. 
     Additionally, cloud callback platform  101  may receive estimated wait time (EWT) information from an enterprise  120  such as a contact center. This information may be used to estimate the wait time for a caller before reaching an agent (or other destination, such as an automated billing system), and determine whether to offer a callback proactively before the customer has waited for long. EWT information may also be used to select options for a callback being offered, for example to determine availability windows where a customer&#39;s callback is most likely to be fulfilled (based on anticipated agent availability at that time), or to offer the customer a callback from another department or location that may have different availability. This enables more detailed and relevant callback offerings by incorporating live performance data from an enterprise, and improves customer satisfaction by saving additional time with preselected recommendations and proactively-offered callbacks. 
     When a customer (consumer or client or end user) calls from a mobile device or uses some communication application such as (for example, including but not limited to) SKYPE™ or instant messaging, which may also be available on a laptop or other network endpoint other than a cellular phone, they may be forwarded to brands  130  operated by a business in the manner described herein. For example, a cellular phone call my be placed over PSTN before being handled by a call router and generating a session with a SIP server, the SIP server creating a session with the cloud callback platform  101  with a profile manager  150  if the call cannot be completed, resulting in a callback being required. 
     A profile manager  150  manages the storage, retrieval, and updating of user profiles, including global and local user profiles. User profiles may include information such as (but not limited to) user devices, services, or subscriptions, an account identifier (e.g., phone number), serial number or other device identifier, a handle or other reference to a resource or username in a communication system (@username of social network, or communication service) or email address, messaging history including any past or ongoing messaging sessions, contextual content associated with a messaging session, and the like. The profile manager  150 , which may be located in the cloud callback platform  101  receives initial requests to connect to cloud callback platform  101 , and forwards relevant user profile information to a callback manager  155 , which may further request context data from a context analysis engine  160 . 
     The context analysis engine  160  may include at least one environment analyzer  161 , at least one sentiment analyzer  162 , and at least one intent analyzer  163 . Context analysis engine  160  may determine, generate, or derive contextual content or attributes associated with a call, data message, or session. Contextual content may include, but are not limited to, attributes derived from a call, data message, or session, such as end user sentiment, emotions, source data, subject matter or topic area of data messages, intended destination data, end user content, end user identification data, intent, a relationship to a second data message, or suggested contact center agent computing device to receive the data message, among other info. Environmental context data may include (for example, and not limited to) recorded information about when a callback requester or callback recipient may be suspected to be driving or commuting from work, for example, and may be parsed from online profiles or online textual data, using an environment analyzer  161 . 
     Present in this embodiment is a sentiment analyzer  162 , which determines or derives sentiment contextual content which may indicate attributes such as end user sentiment or emotions. For example, a customer and contact center agent are having a text chat communication and the cloud callback platform  101  sends a text data message scheduling a callback at 3:15 in the afternoon, but that callback time does not work for the customer so they reply with an thumbs down emoji. The sentiment analyzer  162  may determine the thumbs down emoji indicates a negative sentiment and the cloud callback platform  101  can reschedule the callback  147  and send another text data message with the updated callback time. Also present in this embodiment is an intent analyzer  163 , which analyzes spoken words or typed messages from a user that initiated the callback request, to determine or derive their intent for a callback or the intent of a data message. Intent contextual content may include intended destination data, subject matter or topic area of the callback request or data message. For example, their intent may be to have an hour-long meeting, which may factor into the decision by the cloud callback platform  101  to place a call shortly before one or both users may be required to start commuting to or from their workplace. Context analysis engine  160  or its analyzers  161 ,  162 ,  163  may utilize any combination of text analytics, speech-to-text transcription, audio analysis, facial recognition, expression analysis, posture analysis, or other analysis techniques, and the particular technique or combination of techniques may vary according to such factors as the device type or interaction type (for example, speech-to-text may be used for a voice-only call, while face/expression/posture analysis may be appropriate for a video call), or according to preconfigured settings (that may be global, enterprise-specific, user-specific, device-specific, or any other defined scope). 
     A callback manager  155  centrally manages all callback requests and sessions, creating a callback programming object which may be used to manage the data for a particular callback or initiating a session which may be used to manage the data for a particular data message. For example, when a customer (consumer, client, or callback requester) makes first contact with an enterprise, such as a contact center, via a voice call or text based data message or some other form of communication, the callback manager  155  initiates a session which stores all interactions between the customer and the enterprise. For example, a customer calls a contact center for support and may have to navigate a series of call menus to be routed to the correct department for assistance, but the customer at any point may request a callback or otherwise disconnect the phone call. A session is created for that call interaction and any call menu selections chosen by the customer are stored as session attributes. Similarly, a customer may send one or more data messages to a contact center for support, resulting in the creation of a session facilitating a text based conversation between the customer and a contact center agent, and the customer may at some point request a callback. The messages contained within the session may be considered session attributes. The callback manager  155  may send session attributes to a context analysis engine  160  to determine, generate, or derive contextual content related to at least the callback requester, at least the callback recipient, and at least the session attributes, or some combination therein. Contextual content generated by the context analysis engine  160  may be forwarded to a context aggregator mechanism  175  which generates a context summary report by combining the context content with one or more scripts that may be used by a callback recipient (i.e., enterprise endpoint, contact center agent or bot, etc.) to facilitate timely resolutions to the subject of the callback request. For example, the context content may indicate that the customer (callback requester) was making contact about poor internet connectivity, they have a neutral sentiment, and the wireless device the customer is using hasn&#39;t had its firmware updated since a new firmware update was published. In response, the context aggregator mechanism  175  may identify one or more preconfigured scripts which may allow a callback recipient to proactively manage and remedy the customer&#39;s poor internet connection, for instance, a script may have the callback recipient push the firmware update onto the wireless device remotely and then all the customer would have to do is reset the device. The context summary report may then be sent to the callback manager  155  which can link the context summary report to a callback object. The context summary report may be used in part to identify appropriate callback recipients most qualified to handle the reason for the callback. The callback manager  155  may then provide the context summary report to the callback recipient at the scheduled callback time. For example, the context summary report may be sent to contact center agent computing device at or a few minutes before a scheduled callback time so that the contact center agent may familiarize there self with the context of the callback, so that they may be more responsive to the requests of the customer. 
     The callback manager  155  also communicates with an interaction manager  165  which intercepts data messages and handles requests to make calls and bridge calls, which go out to a media server  170  which either routes the context summary report to an available contact center agent or actually makes the calls as requested. For example, interaction manager  165  may receive a call from a callback requester, retrieve callback parameters for that callback requester from the callback manager  155 , and cause the media server  170  to make a call to a callback recipient while the callback requester is still on the line, thus connecting the two parties. After the call is connected, the callback programming object used to make the connection may be deleted. The interaction manager  165  may subsequently provide changed callback parameters to the callback manager  155  for use or storage. In this way, the media server  170  may be altered in the manner in which it makes and bridges calls when directed, but the callback manager  155  does not need to adjust itself, due to going through an intermediary component, the interaction manager  165 , as an interface between the two. A media server  170 , when directed, may place calls and send data messages, emails, or connect voice over IP (“VoIP”) calls and video calls, to users over a PSTN, the Internet, or some other appropriate communication network  140 . Callback manager  155  may work with a user&#39;s profile as managed by a profile manager  150 , with contextual content from a context analysis engine  160  as well as (if provided) EWT information for any callback recipients (for example, contact center agents with the appropriate skills to address the callback requestor&#39;s needs, or online tech support agents to respond to chat requests), to determine an appropriate callback time for the two users (a callback requestor and a callback recipient), interfacing with an interaction manager  165  to physically place and bridge the calls with a media server  170 . In this way, a user may communicate with another user on a PBX system, or with automated services hosted on a chat server, and if they do not successfully place their call or need to be called back by a system, a cloud callback platform  101  may find an optimal time to bridge a call between the callback requestor and callback recipient, as necessary. 
     In addition to receiving, scheduling, and executing voice callbacks the cloud callback platform  101  may receive a data message. For example, the data message sent from the customer computing device may be sent to a phone number (or other destination identifier such as social media account) of a contact center. Prior to receipt of the data message by a contact center agent computing device or other enterprise endpoint  120  associated with the destination identifier, the interaction manager  165  (or other cloud callback platform  101  component) may intercept (e.g., receive, hook, access, or otherwise obtain) the data message. Once a data message has been received by the interaction manager  165  the profile manager  150  may send relevant profile information to the callback manager  155  which may initiate a session responsive to the received data message. The callback manager  155  may copy or replicate the data message to generate a replicated data message. The replicated data message may include the subject matter (i.e., session attributes) of the data message, and may also include an identifier indicating that it is a replication or indicating the source (or other information) of the data message. For example, the callback manager  155  may tag the replicated data message with a unique identifier that indicates the source of the data message. The callback manager  155  may tag the corresponding original data message with the same or a different (e.g., related) unique identifier indicating that the data messages are copies of one another. The callback manager  155  may provide the replicated data messages (including any identifiers) to the profile manager  150  for storage and retrieval by components of the cloud callback platform  101 . The identifiers can be stored with the session or linked to the sessions, e.g., via a lookup table. 
     The cloud callback platform  101  may receive a data message via the communication network  140 . The data message may include a text message sent from a consumer endpoint  110  (e.g., customer computing device) to an enterprise endpoint  120  (e.g., contact center environment intended for a contact center agent computing device) or user brand  130 . The data message may be text or image based. The data message may also be an asynchronous voice transmission (e.g., a voicemail or voice message) that is recorded by the customer computing device and then transmitted, rather than a live voice conversation. For example, the end user at the customer computing device may have a question about a cable television bill and may send a text or other text-based data message, or a voicemail message, to a contact center to obtain assistance from a representative. This text based data message can be received by the cloud callback platform  101 . The voicemail message may be translated to text by the customer computing device, or can be provided as an audio file. Data messages can be asynchronous, e.g., one-way, separated in time or having different subject matter content. 
     The text based data message (or alternatively, a voice call, voice mail, or session) can include one or more attributes. Attributes of the data message may indicate a source of the data message, such the device from which the data message originated, a network account or social network account from which the data message originated, or an individual from which the data message originated. For example, packet or other protocol based transmissions of data messages can include a media access control address, network interface controller, Ethernet hardware address, programmed address, or other identifier that identifies the consumer endpoint  110  (e.g., a smart phone or tablet or other computing device). 
     For example, the attribute can include a handle or other reference to a resource or username in a communication system (e.g., ‘@username’ of a social network or communication service) or an email address. The attribute can also include an account identifier (e.g., a phone number of a smartphone or identifier of a social media or email account), serial number, or other device identifier. The attribute can accompany the text based data message transmitted from a consumer endpoint  110  (e.g., customer computing device) and received by the cloud callback platform  101 , e.g., on behalf of a contact center. For example, the attribute can be included within or appended to packet or other protocol based transmissions of the data message through the network  140 . The attribute can also be indicated by metadata or header information that is part of or transmitted with the data message. Characteristics may be used by the cloud callback platform  101  profile manager  150  to identify and located the correct profile of the originator of the data message. The attribute can also include or be indicated by subject matter of the data message. For example, cloud callback platform  101  may determine the attribute of the data message from the subject matter (e.g., words, symbols, phrases, punctuation, abbreviations, misspellings, emojis, or keywords) of the data message that can indicate attributes such as an end user sentiment, such as happy, content, angry, upset, rushed, or annoyed. 
     The context analysis engine  160  may parse or evaluate the data message (including any metadata such as a location, keyword, topic, or phone number) to identify at least one attribute of the data message (e.g., subject matter of the data message, or an identifier of the end user or of the customer computing device). For example, data messages may include source and destination addresses, formatted such as @thomas for social networks or +15085551212 for mobile telcom networks, along with the payload of the message, such as “I have a problem with my bill”, and various meta-data about the message such as the time of creation, a unique identifier for the message, or a Boolean flag indicating whether or not the data message has been delivered before. Based on these attributes, the context analysis engine  160  may identify attributes of the data messages, and can generate corresponding contextual content, such as a sentiment analysis or determination for the data message. The handle identifier “@Thomas” and the destination identifier ‘@Cable Co” are examples and the attributes of the data messages. The attributes of the data message may include other identifiers, such as subject matter terms, a phone number of the customer computing device, a device identifier of the customer computing device, destination phone numbers or other identifiers of the entity that is associated with the data message (e.g., that the end user is trying to reach). 
     The cloud callback platform  101  may generate, (e.g., identify, or obtain) contextual content of or corresponding to the session or a data message. For example, the context analysis engine  160  may parse or analyze the replicated data message or the original data message (or attributes/attributes thereof) to identify contextual content. The contextual content may indicate a sentiment or other attribute of the end user at the consumer endpoint  110  that originated the data message, or may indicate a topic or category of content of the data message, for example. The context analysis engine  160  may link the contextual content with the data message (or replicated data message) and can provide the contextual content to the profile manager  150  for storage and subsequent retrieval. 
     The callback manager  155  may fork (e.g., copy or replicate) the session or data message. The callback manager  155  may provide (a copy of) the data message to the context analysis engine  160 , and may provide (another copy of) the data message to the aggregator mechanism  175 . The interaction manager  165  may include a processor, controller, or logic circuitry that can execute a script or application to hook or intercept the data message and the callback manager  155  to provide copies of the data message to the context analysis engine  160  or to the context aggregator mechanism  175 . For example, the intercepted data message can be tagged by the cloud callback platform  101  with a globally unique identifier to track the original source of the duplicated data message before passing the original message to the aggregator mechanism  175 . The original data message can then be duplicated and tagged with a second globally unique identifier and passed to the context analysis engine  175 . 
     When a data message is received by the cloud callback platform  101  the callback manager  155  initiates and manages a session to facilitate interactive information exchange. For example, a cable customer may login on to a cable provider&#39;s website and send a data message (e.g., “My cable bill is too expensive”) via a pop-up chat window to a customer support contact center. The received data message or session details may be sent to a context aggregator mechanism  175  and to a context analysis engine  160 . The context analysis engine  160  may parse the data message to determine or derive contextual content for or of data messages. For instance, from the data message “My cable bill is too expensive” the context analysis engine  160  may determine that the customer wants to be directed to billing and that he/she has negative sentiment. This contextual content may be sent to the profile manager  150  for storage or sent to the context aggregator mechanism  175  which can combine (e.g., merge, integrate, associate, or append) the contextual content with the data message (original or replicated) to create a context summary report. The context summary report may be one or more than one data packet (or other protocol based) data structure. The cloud callback platform  160  may provide the context summary report to at least one contact center agent computing device for display, e.g., via a live interaction component of the contact center computing device, or other enterprise endpoints  120  or user brands  130 . Cloud callback platform  101  by enhancing or modifying data messages to include contextual content reduces the number of packet (or other protocol based) computer network transmissions that may otherwise occur due to inefficient routing to, for example, unnecessary additional data message communications or unnecessary transfers or hops to incorrect destinations (e.g., wrong contact center agent computing device) before arriving at the correct destination. This saves bandwidth, reduces latency, saves power, and results in faster communications between the end user computing device and the correct contact center computing device. 
     When the context summary report is received at an enterprise endpoint  120 , such as a contact center agent computing device, it may be displayed on some live interaction component of the computing device. The context summary report provides the contact center agent computing device with the original data message and with any contextual content determined or derived by the cloud callback platform  101 . The contextual content may provide information that allows a contact center agent (or bot or script or some combination) to proactively address the reason why the customer sent a data message. 
       FIG.  2    is a functional diagram of a system  200  for a cloud callback platform, generating a context summary report, according to an embodiment. The system  200  may include a contact environment (e.g., call center, customer service, or help desk environment that includes the ability to route, service, and respond to voice calls or non-voice data message communications). A customer, via a computing device, may make contact with a contact center by sending at least one (first) data message  205  via a communication network  140 . The data message  205  may include at least one attribute  210 , such as a source, destination, subject matter, end user, or computing device information from which context content  215  may be determined or identified. For example, the first data message  205  may include a message to an internet service provider contact center that states “I&#39;m not happy with my internet service” and can include metadata or other information such as a user identifier, social media handle, or phone number that identifies the source of the first data message  205 . The callback manager  155  may initiate a session when a first data message  205  is received by the cloud callback platform  101 . The callback manager  155  may replicate and store the first data message  205 . The callback manager  155  may provide the data message  205 , a replication of the data message, or session details  210  to a context analysis engine  160 . The callback manager  155  may provide the session or first data message  205  (with or without a context summary  220 ) to the contact center agent computing device  225 . 
     The cloud callback platform  101  in the contact center environment can determine that data messages are (or are not) part of a pre-existing session. The session may be a voice connection or text based communication session between the end user and a contact center agent or other representative at the contact center agent computing device  225 . Multiple individual data messages  205  can be aggregated or clustered together to form or define a session. For example, a series of back and forth text messages between the customer computing device and the contact center agent computing device  225  that pertain to common subject matter such as a billing query can be identified by the callback manager  155  as a session. Multiple, different data messages  205  from the same session can be evaluated by the context analysis engine  160  to determine context content  215 . The callback manager  155  can provide the sessions for storage in and retrieval from a profile manager  150 . 
     The cloud callback platform  101  may assemble or aggregate data messages  205  into logical groups called sessions. Unlike other real time communications modes like audio and video that have an explicit start and stop to a conversation, data messages via messaging based networks can be considered stateless, e.g., without explicit indications of beginnings and ends of conversations, such as disconnecting a voice call. The callback manager  155  can mark the beginning and end of sessions, e.g., conversations. The callback manager  155  may append newly received data messages  205  to a pre-existing session, or can create a new session for the data message  205 . The context aggregator mechanism  175  can create context summary reports  220  that include data messages  205  as well as context content  215 . The cloud callback platform  101  may also collect meta-data information about the source of the inbound data message  205 , including attributes such as the network identifier, subject matter, words, phrases, symbols, keywords, messaging network, device location, and in the case of social messaging or with end user consent, details such as the parties name or telephone number. The cloud callback platform  101  may send a confirmation receipt message to the originating party (e.g., the customer computing device), responsive to receipt of a data message  205 . 
     The context aggregator mechanism  175  may receive from the context analysis engine  160  context content  215  which may be combined with one or more pre-configured scripts to generate a context summary report  220 . The context summary report  220  may parse, compile, and format the received context content  215  into a human or machine readable report. The context summary  220  may be sent to the callback manager  155  where it may be linked to a callback object and stored with a user profile in a profile manager  150 . The callback manager  155  may send the context summary report  220  to a contact center agent computing device  225  either at or before a callback is scheduled. 
     Providing the context summary reports  220  that include the data message  205  and supplemental content (e.g., context content  215 ) to the contact center agent computing device  225  leverages the transfer or routing of prior data messages as, for example, the context content used to enhance a second data message  205  can be responsive to a first data message  205 . This results in more efficient or more direct routing or processing of data messages  205  and can lead to faster conclusions of sessions between the customer computing device and the contact center environment that includes the cloud callback platform  101 . The more efficient routing and processing reduces the volume of computer network data transmissions and computer processing operations, which reduces latency, saves processing capacity, and saves electrical power relative to contact center environment that does not include context summary reports  220 . 
       FIG.  3    is a block diagram illustrating an exemplary system architecture for a cloud callback platform including a calendar server operating over a public switched telephone network and the Internet, and connected to a variety of other brand devices and services, according to an embodiment. According to this embodiment, many user brands  310  are present, including PBX system  311 , a SIP server  312 , a CRM server  313 , a call router  314 , and a chat server  315 , which may be connected variously to each other as shown, and connected to a PSTN  303  and the Internet  302 , which further connect to a cellular phone  305  and a landline  304  or other phone that may not have internet access. As further shown, cloud callback platform  320  contains multiple components, including a calendar server  321 , profile manager  322 , context analysis engine  323 , callback manager  324 , interaction manager  325 , media server  326 , and a data message aggregator  327 , which similarly to user brands  310  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  303  or the internet  302 . 
     A calendar server  321 , according to the embodiment, is a server which may store and retrieve, either locally or from internet-enabled services associated with a user, calendars which hold data on what times a user may be available or busy (or some other status that may indicate other special conditions, such as to allow only calls from certain sources) for a callback to take place. A calendar server  321  connects to the internet  302 , and to a profile manager  322 , to determine the times a callback requestor and callback recipient may both be available. 
       FIG.  4    is a block diagram illustrating an exemplary system architecture for a cloud callback platform including a brand interface server, operating over a public switched telephone network and the Internet, and connected to a variety of other brand devices and services, according to an embodiment. According to this embodiment, many user brands  410  are present, including PBX system  411 , a SIP server  412 , a CRM server  413 , a call router  414 , and a chat server  415 , which may be connected variously to each other as shown, and connected to a PSTN  303  and the Internet  302 , which further connect to a cellular phone  305  and a landline  304  or other phone that may not have internet access. As further shown, cloud callback platform  420  contains multiple components, including a profile manager  421 , context analysis engine  422 , callback manager  423 , interaction manager  424 , media server  425 , and a data message aggregator  426 , which similarly to user brands  410  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  303  or the internet  302 . 
     Present in this embodiment is a brand interface server  430 , which may expose the identity of, and any relevant API&#39;s or functionality for, any of a plurality of connected brands  410 , to elements in a cloud callback platform  420 . In this way, elements of a cloud callback platform  420  may be able to connect to, and interact more directly with, systems and applications operating in a business&#39; infrastructure such as a SIP server  412 , which may be interfaced with a profile manager  421  to determine the exact nature of a user&#39;s profiles, sessions, and interactions in the system for added precision regarding their possible availability and most importantly, their identity. 
       FIG.  5    is a block diagram illustrating an exemplary system architecture for a cloud callback platform including a privacy server, operating over a public switched telephone network and the Internet, and connected to a variety of other brand devices and services, according to an embodiment. According to this embodiment, many user brands  510  are present, including PBX system  511 , a SIP server  512 , a CRM server  513 , a call router  514 , and a chat server  515 , which may be connected variously to each other as shown, and connected to a PSTN  303  and the Internet  302 , which further connect to a cellular phone  305  and a landline  304  or other phone that may not have internet access. Further shown is a cloud callback platform  520  contains multiple components, including a profile manager  521 , context analysis engine  522 , callback manager  523 , interaction manager  524 , media server  525 , and a data message aggregator  527 , which similarly to user brands  510  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  303  or the internet  302 . 
     In this embodiment, a privacy server  521  may connect to the internet  302 , and to a profile manager  522  as well as a callback manager  524 , and allows for callback requestors to first be validated using trust-circles to determine if they are a trusted user. A trusted user may be defined using a variety of criteria (that may vary according to the user, interaction, device, enterprise, or other context), and may for example comprise a determination of whether the callback requestor is a friend or family member, or is using a trusted brand such as a piece of equipment from the same company that the callback recipient works at, or if the callback requestor is untrusted or is contacting unknown recipients, to determine if a callback request is permitted based on user settings. Further, a privacy server  521  may encrypt one or both of incoming and outgoing data from a callback manager  524  in such a way as to ensure that, for example, a callback recipient might not know who requested the callback, or their profile may not be visible to the recipient, or vice versa, and other privacy options may also be enabled as needed by a corporation. Encryption may utilize public or private keys, or may utilize perfect forward secrecy (such that even the enterprise routing the call cannot decrypt it), or other encryption schema or combinations thereof that may provide varying features or degrees of privacy, security, or anonymity (for example, one enterprise may permit anonymous callbacks while another may require a user to identify themselves and may optionally verify this identification). 
       FIG.  6    is a block diagram illustrating an exemplary system architecture for a cloud callback platform including a bot server, operating over a public switched telephone network and the Internet, and connected to a variety of other brand devices and services, according to an embodiment. According to this embodiment, many user brands  610  are present, including PBX system  611 , a SIP server  612 , a CRM server  613 , a call router  614 , and a chat server  615 , which may be connected variously to each other as shown, and connected to a PSTN  303  and the Internet  302 , which further connect to a cellular phone  305  and a landline  304  or other phone that may not have internet access. As further shown, a cloud callback platform  620  contains multiple components, including a profile manager  622 , context analysis engine  623 , callback manager  624 , interaction manager  625 , media server  626 , and a context aggregator mechanism  627 , which similarly to user brands  610  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  303  or the internet  302 . 
     In the present embodiment, a bot server  624  also is present in a cloud callback platform  620 , which allows for communication with a callback requestor. Bot server  624  allows a user to specify, through any available data type such as (including, but not limited to) SMS texting, email, or audio data, any desired parameters for the callback they would like to request. This is similar to an ACD system used by individual call-centers, but exists as a separate server  624  in a cloud callback platform  620  which may then be configured as-needed by a hosting company, and behaves akin to an automated secretary, taking user information down to specify a callback at a later time from the callback recipient. 
       FIG.  7    is a block diagram illustrating an exemplary system architecture for a cloud callback platform including an operations analyzer operating over a public switched telephone network and the Internet, and connected to a variety of other brand devices and services, according to an embodiment. According to this embodiment, many user brands  710  are present, including PBX system  711 , a SIP server  712 , a CRM server  713 , a call router  714 , and a chat server  715 , which may be connected variously to each other as shown, and connected to a PSTN  303  and the Internet  302 , which further connect to a cellular phone  305  and a landline  304  or other phone that may not have internet access. As further shown, a cloud callback platform  720  contains multiple components, including a profile manager  721 , context analysis engine  722 , callback manager  723 , interaction manager  725 , media server  726 , and a context aggregator mechanism  727 , which similarly to user brands  710  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  303  or the internet  302 . 
     In this embodiment, an operations analyzer  724  is present, which may determine a particular channel to be used to reach a callback recipient and callback requestor, for example (and not limited to), VoIP services such as SKYPE™ or DISCORD™, a PSTN phone connection, any particular phone number or user accounts to connect using, or other service, to determine the optimal method with which to reach a user during a callback. An operations analyzer  724  may also analyze and determine the points of failure in a cloud callback platform  720 , if necessary, for example if a callback attempt fails to connect operations analyzer  824  may bridge a callback requestor and recipient using an alternate communication channel to complete the callback at the scheduled time. 
       FIG.  8    is a block diagram illustrating an exemplary system architecture for a cloud callback platform including a brand interface server, an intent analyzer, and a broker server, operating over a public switched telephone network and internet, and connected to a variety of other brand devices and services, according to an embodiment. According to this embodiment, many user brands  810  are present, including PBX system  811 , a SIP server  812 , a CRM server  813 , a call router  814 , and a chat server  815 , which may be connected variously to each other as shown, and connected to a PSTN  303  and the Internet  302 , which further connect to a cellular phone  305  and a landline  304  or other phone that may not have internet access. As further shown, a cloud callback platform  820  contains multiple components, including a profile manager  821 , context analysis engine  822 , callback manager  823 , interaction manager  825 , media server  826 , and a context aggregator mechanism  826 , which similarly to user brands  810  may be interconnected in various ways as depicted in the diagram, and connected to either a PSTN  303  or the internet  302 . 
     Present in this embodiment is a brand interface server  830 , which may expose the identity of, and any relevant API&#39;s or functionality for, any of a plurality of connected brands  810 , to an intent analyzer  840 . In this way, elements of a cloud callback platform  820  may be able to connect to, and interact more directly with, systems and applications operating in a business&#39; infrastructure such as a SIP server  812 , which may be interfaced with a profile manager  821  to determine the exact nature of a user&#39;s profiles, sessions, and interactions in the system for added precision regarding their possible availability and most importantly, their identity. An intent analyzer  840  may analyze spoken words or typed messages from a user that initiated the callback request, to determine their intent for a callback, as well as forward data received from a brand interface server. For example, their intent may be to have an hour-long meeting, which may factor into the decision by a cloud callback platform  820  to place a call shortly before one or both users may be required to start commuting to or from their workplace. An intent analyzer  840  may forward all data through a broker server  850  which may allocate specific actions and responses to take between third-party brands  810  and cloud callback platform  820  components, as needed, as well as forward all data from the exposed and interfaced elements with the cloud callback platform  820 . 
       FIG.  9    is a diagram illustrating trust circles of levels of privacy for a user of a cloud callback platform, according to an aspect. These trust circles are data constructs enforced by a privacy server  621  which are determined with a profile manager  622 , which indicate the level of trust that callers may possess, and therefore the system&#39;s ability to schedule a callback with the caller and the recipient. A caller who calls from a recognized brand  910 , for example a company&#39;s phone forwarded through their PBX  611 , may be recognized as having the highest level of trust, due to coming from a recognized source within the same organization. Family  920  may (for example) be the second highest level of trust, allowing for just as many privileges with callbacks, or perhaps restricting callback requests to only certain hours, to prevent users from being disrupted during certain work hours. A callback recipient&#39;s friends  930  may occupy a level of trust lower than that of family, representing users less-trusted than family  920  callers, and may yet have more restricted access to making callback requests for a user, and a continuing, descending hierarchy may be used to model additional levels of trust. For example, additional trust levels may include (but are not limited to) social media  940  recognized users, colleagues  950  which may represent individuals only loosely affiliated with a potential callback recipient, and untrusted  960 , representing users who are known to the system and deemed banned or untrustworthy, having the lowest ability to request an automated callback connection with a user. A further level of trust may exist, outside of the trust-circle paradigm, representing unknown contacts  970 , which, depending on the settings for an individual user or an organization using a cloud callback platform system  620 , may be unable to request callbacks, or may only be able to request callbacks at certain restricted hours until they are set to a higher level of trust in the system, according to a preferred embodiment. 
     As shown in  FIG.  9   , trust circles need not be implicitly hierarchical in nature and may overlap in various ways similar to a logical Venn diagram. For example one individual may be a friend and also known on social media, or someone may be both family and a colleague (as is commonplace in family businesses or large companies that may employ many people). As shown, anybody may be considered “untrusted” regardless of their other trust groupings, for example if a user does not wish to receive callbacks from a specific friend or coworker. While the arrangement shown is one example, it should be appreciated that a wide variety of numerous overlapping configuration may be possible with arbitrary complexity, as any one person may be logically placed within any number of groups as long as the trust groupings themselves are not exclusive (such as a group for coworkers and one for individuals outside the company). 
     Expanding on the notion of trust circles, there may also be logical “ability” circles that correspond to various individuals&#39; capabilities and appropriateness for various issues, such as (for example) tech support skill or training with specific products, or whether a member of a brand  910  is actually a member of the best brand to handle a specific reason for a callback, based on the callback request context. For example, a customer requesting a callback for assistance with booking a flight may not be adequately served by employees of airlines that don&#39;t offer flights to their intended destination, so combining the brand trust zone  910  with a capability map would indicate to the callback system which individuals are more appropriate for the callback in question. This expands from merely trusting certain users and discarding others, to a form of automated virtual concierge service that finds the user for a callback request that is most capable and relevant to the request, ensuring optimum handling of the callback requestor&#39;s needs. 
       FIG.  13    is a block diagram illustrating an exemplary system architecture  1300  for a cloud callback platform further comprising an exemplary system for secure transitory data storage and management, according to one embodiment. According to an embodiment, cloud callback platform  101  may further comprise a vault manager  1310  which may be used to implement a system for secure transitory data storage and management. Vault manager  1310  may be used to store data containers, encrypt the data stored in a data container, and manage data container interactions. A data container may be created as a temporary repository for user-selected preferences which may be shared with another user. In addition to user-selected preferences, a data container creator may also define container access rules which place limits on the accessibility and availability of data put inside the data container. In this way, consumers may have greater control over their own data by allowing them to choose which of their data to share and by allowing them to define rules which govern access to their data. Consumers  110 , enterprises  120 , and user brands  130  can all create a data container. Data containers may be identified by and linked to the personal phone number of the individual or entity which created the data container. 
     Prior to executing a phone call an individual or entity may create a data container, identified by the personal phone number of the container creator, which may be used to store a set of preferences. The phone call may then be executed and intercepted by interaction manager  165  which forwards the intercepted call to a callback manager  155  which creates a callback object. Upon creation of the callback object, the callback manager  155  may forward the phone number associated with the intercepted call to vault manager  1310 . Responsive to the received phone number, vault manager  1310  retrieves the data container, identified by the received phone number, from the computing device of the container creator. After the correct container has been retrieved, vault manager  1310  combines the phone numbers of the callee and the intended call recipient and creates a hash used as a password for access to the preferences stored in the data container. The created password has the properties of being unique and ephemeral in that it only lasts as long as the user-defined access rules stipulate. Vault manager  1310  may also encrypt the data stored in the data containers, adding additional data privacy and security resilience on top of the generated hash password. The encrypted data container may be stored within a database for storage until the container is deleted by its creator or until the user-defined time period of container existence is surpassed. At this point, if the call recipient is available then the cloud callback platform  101  will connect the two parties (the callee and call recipient) and the call recipient (or the other of the two parties which did not create the data container), via a computing device, will be prompted to comply with the user-defined container access rules. If the call recipient agrees to comply with the user-defined rules, then the call recipient will be able to access the data container. If, however, the call recipient does not agree to comply with the user-defined rules, then the call recipient will not be able to access the data container. If the call cannot be connected, then a callback may be scheduled and the data container may be placed in storage and linked to the callback object associated with the intercepted call. At the later scheduled callback time, the data container may be retrieved from storage and sent to the callback recipients computing device upon agreement of user-defined rules. 
     As an example, a junior software engineer may want to discuss with a senior engineer a section of code which is particularly buggy and not producing the required output. Prior to calling the senior engineer, the junior engineer creates a data container and places the section of code in the data container. The junior engineer defines the access rules of the container by giving access to the senior engineer for a time period of one week as well as granting editing permissions to the senior engineer. The junior engineer calls the senior engineer and during their call the data container is retrieved and a hash password is created using the personal phone numbers of both the junior and senior engineer. The senior engineer could then view the buggy section of code and edit it as necessary while talking on the phone with the junior engineer. 
     Cloud callback platform  110 , via vault manager  1310 , may be able to generate default data containers for callee&#39;s who have not created a data container. When a system user places a call or sends a data message, interaction manager  165  may intercept the call or data message and the callback manager  155  creates a callback object. If vault manager  1310  cannot locate and retrieve a data container, then any available profile information associated with the callee or data message sender may be sent from profile manager  150  to vault manager  1310 . Additionally, context analysis engine  160  may determine context content data derived from the call or data message and send the context content data to vault manager  1310 . Vault manager  1310  may create a default container with default preferences based upon profile information and context content data. The default data container may then be encrypted and a hash password created to limit container access to only the callee and call recipient. 
     As an example, a consumer logs onto a bank&#39;s website and begins a webchat asking about home lending rates and refinancing, but in the middle of the conversation the consumer forgot he had to pick his kids up from school and quickly requests a callback to continue the conversation. Prior to the webchat the consumer did not set up a data container. Cloud callback platform  101  may feed the webchat messages into the context analysis engine  160  which determines context content data which indicates the consumer was interested in securing a home loan. Vault manager  1310  may use this context content data to create a default data container in which the consumer can place the required documentation needed when applying for a home loan, such as tax statements, proof of income, proof of identification, etc. This default data container may then be stored and linked to the callback object associated with the consumer. Prior to the scheduled callback time, the consumer may view the default data container and define the access rules for the default container. In another embodiment, vault manager  1310  may establish default access rules for a created default data container. In the case of a default container for home loan application, default rules may be defined such that access is restricted to the consumer and a bank loan officer, an access time limit of 30 days, and read-only access to the data contained therein. These default rules may be amended by the consumer at his discretion. When the scheduled callback is executed the consumer and the loan officer may both access the default data container and the loan officer may instruct the consumer how to upload the required data to the default container in order to start the home loan application process. 
       FIG.  14    is a block diagram illustrating an exemplary aspect of a system for secure transitory data storage and management, a vault manager  1310 , according to an embodiment. According to an embodiment, vault manager  1310  may comprise a container retriever  1400 , an encryption and security module  1410 , a default container module  1420 , an audit logger  1430 , a vault storage device  1440 , and a domain-specific database(s)  1450 . Container retriever  1400  may receive a container identifier  1401  from callback manager  155 . In a preferred embodiment, the container identifier  1401  may be a personal phone number associated with the creator of the data container object. In other embodiments, the container identifier  1401  may be, for example, a username, social media handle, email address, or other unique identifier. Container retriever  1400  may retrieve containers and container data  1403  from a computing device associated with individual or entity associated with the container identifier  1401 . After a container has been retrieved, an encryption and security module  1410  may be used to create a password for accessing the data container as well as encrypt the data contained within the data container. In one embodiment, the personal phone number of the container creator (e.g., caller) and the personal phone number of a call recipient may be combined by encryption and security module  1410  in order to create a hash to act as a time bound security key for accessing the data container. To encrypt the data located within the container, encryption and security module  1410  may use one or more of the numerous encryption methods known to one skilled in the art including, but not limited to, symmetric key cryptography where the sender and receiver share a similar key that can be used for encryption and decryption, hash functions where there is no key just a hash value to encrypt, and public key cryptology where two keys exist, a public key for encryption and a private key is used for decryption. Once the data container has been encrypted, it may be sent to vault storage  1440  for temporary storage until the container is deleted by its creator or until the creator-defined lifetime of the container is surpassed. 
     Vault manager  1310  may establish default preferences stored inside a default data container if a caller or data message sender does not have or has not created his or her own preferences. According to an embodiment, vault manager  1310 , via a default container module  1420 , may receive profile data  1402  associated with a callee or data message sender, if any such profile data is available. Profile data  1402  may comprise the following, but is not limited to, username, email, phone number, and any other unique identifier, preferred callback mode (e.g., text message, phone call, webchat, etc.), availability, and other user preferences. Default container module  1420  may also receive context content data  1404  which is context data derived from user interactions with cloud callback platform  101 . Default container module  1420  may use the available profile data  1402  when defining the default access rules for the default container. If there is no available profile data  1404 , then default container module  1420  may reference domain-specific database(s)  1450  to retrieve any pre-defined domain specific rules that may exist. Domain-specific database(s)  1450  may store a variety of data related to a domain related to a given enterprise which may be utilizing cloud callback platform  101 . For example, a banking institution utilizing cloud callback platform  101  may define default container-access rules for each of the different divisions of the company: advertising, public relations, auto loans, home loans, teller activities, management, and accounting could all have their own set of access rules defined by the bank. In addition to the pre-defined rules, for each of the different divisions there could also be pre-selected preferences associated with default containers created for that division (e.g., domain). Default container manager  1420  may create a default data container for a system user by using the received context content data  1404  and, if available, pre-defined domain-specific rules and preferences stored in domain-specific database(s)  1450 . Once a default data container has been created the container data is then encrypted and a container password may be created. The encrypted data container may be stored in vault storage  1440 . The default container is then linked to the callback object associated with initial caller or data message sender, and may be retrieved when the scheduled callback is executed. After creation of the default data container and prior to the scheduled callback executing, the caller may receive an alert (e.g., text notification) that a data container has been created responsive to caller initiated callback request and that it is available for review. During review, the caller can view, edit, or approve the default rules and preferences. 
     According to an embodiment, vault manager  1310  may comprise an audit logger  1430  which may record a detailed audit log to track what individuals or entities may be accessing a data container and to track any changes that may be made to data stored within a data container. There are a number of suitable ways known to one skilled in the art for tracking and logging access to systems and applications. In one embodiment, vault manager  1310  may implement a blockchain to implement an audit logger  1430  for tracking and logging access to data containers and the data stored therein. 
       FIG.  17    is a block diagram illustrating an exemplary system architecture  1700  for a cloud callback platform further comprising an exemplary system for secure storage and management of transitory data using blockchain, according to one embodiment. According to an embodiment, cloud callback platform  101  may further comprise a vault manager  1310  and a blockchain manager  1800 . Vault manager  1310  may be used to store data containers, encrypt the data stored in a data container, and manage data container interactions. A data container may be created as a temporary repository for user-selected preferences which may be shared with another user. In addition to user-selected preferences, a data container creator may also define container access rules which place limits on the accessibility and availability of data put inside the data container. In this way, consumers may have greater control over their own data by allowing them to choose which of their data to share and by allowing them to define rules which govern access to their data. Consumers  110 , enterprises  120 , and user brands  130  can all create a data container. Data containers may be identified by and linked to the personal phone number of the individual or entity which created the data container. Blockchain manager  1800  may be used to store encrypted data containers, received from vault manager  1310 , which can contain transitory data in a blockchain structure, generate block reference data which can be encrypted, stored off the blockchain, and distributed to involved parties to grant access to the block which stores the encrypted data container. Blockchain manager  1800  also provides the ability to delete data containers and/or the block reference data based upon one or more self-destruct event triggers that can be applied to a data container during or at any time after the creation of a data container. The use of self-destruct triggers and reference block data effectively allows the system to “delete” the transitory data stored within the encrypted data container on the blockchain by deleting one or more encryption keys associated with the block, the encrypted data container, and/or the block reference data. 
     Prior to executing a phone call an individual or entity may create a data container, identified by the personal phone number of the container creator, which may be used to store a set of preferences. The phone call may then be executed and intercepted by interaction manager  165  which forwards the intercepted call to a callback manager  155  which creates a callback object. Upon creation of the callback object, the callback manager  155  may forward the phone number associated with the intercepted call to vault manager  1310 . Responsive to the received phone number, vault manager  1310  retrieves the data container, identified by the received phone number, from the computing device of the container creator. After the correct container has been retrieved, vault manager  1310  combines the phone numbers of the callee and the intended call recipient and creates a hash used as a password for access to the preferences stored in the data container. The created password has the properties of being unique and ephemeral in that it only lasts as long as the user-defined access rules stipulate. Vault manager  1310  may also encrypt the data stored in the data containers, adding additional data privacy and security resilience on top of the generated hash password. The encrypted data container may be stored within a database for storage until the container is deleted by its creator or until the user-defined time period of container existence is surpassed. At this point, if the call recipient is available then the cloud callback platform  101  will connect the two parties (the callee and call recipient) and the call recipient (or the other of the two parties which did not create the data container), via a computing device, will be prompted to comply with the user-defined container access rules. If the call recipient agrees to comply with the user-defined rules, then the call recipient will be able to access the data container. If, however, the call recipient does not agree to comply with the user-defined rules, then the call recipient will not be able to access the data container. If the call cannot be connected, then a callback may be scheduled and the data container may be placed in storage and linked to the callback object associated with the intercepted call. At the later scheduled callback time, the data container may be retrieved from storage and sent to the callback recipients computing device upon agreement of user-defined rules. 
     As an example, a junior software engineer may want to discuss with a senior engineer a section of code which is particularly buggy and not producing the required output. Prior to calling the senior engineer, the junior engineer creates a data container and places the section of code in the data container. The junior engineer defines the access rules of the container by giving access to the senior engineer for a time period of one week as well as granting editing permissions to the senior engineer. The junior engineer calls the senior engineer and during their call the data container is retrieved and a hash password is created using the personal phone numbers of both the junior and senior engineer. The senior engineer could then view the buggy section of code and edit it as necessary while talking on the phone with the junior engineer. 
     Cloud callback platform  110 , via vault manager  1310 , may be able to generate default data containers for callee&#39;s who have not created a data container. When a system user places a call or sends a data message, interaction manager  165  may intercept the call or data message and the callback manager  155  creates a callback object. If vault manager  1310  cannot locate and retrieve a data container, then any available profile information associated with the callee or data message sender may be sent from profile manager  150  to vault manager  1310 . Additionally, context analysis engine  160  may determine context content data derived from the call or data message and send the context content data to vault manager  1310 . Vault manager  1310  may create a default container with default preferences based upon profile information and context content data. The default data container may then be encrypted and a hash password created to limit container access to only the callee and call recipient. 
     As an example, a consumer logs onto a bank&#39;s website and begins a webchat asking about home lending rates and refinancing, but in the middle of the conversation the consumer forgot he had to pick his kids up from school and quickly requests a callback to continue the conversation. Prior to the webchat the consumer did not set up a data container. Cloud callback platform  101  may feed the webchat messages into the context analysis engine  160  which determines context content data which indicates the consumer was interested in securing a home loan. Vault manager  1310  may use this context content data to create a default data container in which the consumer can place the required documentation needed when applying for a home loan, such as tax statements, proof of income, proof of identification, etc. This default data container may then be stored and linked to the callback object associated with the consumer. Prior to the scheduled callback time, the consumer may view the default data container and define the access rules for the default container. In another embodiment, vault manager  1310  may establish default access rules for a created default data container. In the case of a default container for home loan application, default rules may be defined such that access is restricted to the consumer and a bank loan officer, an access time limit of 30 days, and read-only access to the data contained therein. These default rules may be amended by the consumer at his discretion. When the scheduled callback is executed the consumer and the loan officer may both access the default data container and the loan officer may instruct the consumer how to upload the required data to the default container in order to start the home loan application process. 
       FIG.  18    is a block diagram illustrating an exemplary aspect for a system architecture for secure storage and management of transitory data using blockchain technology, the blockchain manager. According to the aspect, blockchain manager  1800  comprises a blockchain ledger  1810  which can store one or more blockchain  1811  structures, a self-destruct module  1820  which monitors for self-destruct events or triggers and executes an action responsive to an event or trigger occurring, a block reference creator  1840  which generates block reference data comprising at least a location a block which stores an encrypted data object (e.g., data container) and the decryption key associated with the encrypted data object, and which stores the reference block data off of blockchain  1811  in a block reference database  1830 . 
     According to the embodiment, blockchain manager  1800  is configured to store an encrypted data object full of transitory data in a blockchain  1811  stored in blockchain ledger  1810 , generate block reference data comprising the location of the block and its decryption key, store block reference data off the blockchain (where it can be destroyed), and generate a second encryption key that decrypts the block reference data. Involved parties are given (granted permission/access) the second key, which allows them to decrypt and read the block reference data. In order to “delete” the transitory data, the block reference data and thus the block&#39;s decryption key are destroyed. As a result, the user&#39;s decryption key is now useless because it only decrypts the destroyed data and contains no blockchain information of its own. 
     According to the embodiment, self-destruct module  1820  is configured to perform user authentication, to monitor data container/block access for potential threats or compromises as well as for events and triggers, and to execute data deletion tasks when a self-destruct event is encountered. For example, a self-destruct event occurs and self-destruct module  1820  executes a deletion task which results in the deletion of the reference block data associated with a block on blockchain  1811 . Self-destruct events can include, but are not limited to, timer-based events, trigger packet based events, and/or device-based trigger events. A timer-based event may be defined, for example, such that a data object expires after a scheduled callback, preventing data remnants that could leak information. A timer-based event can be defined by a user as a data container access rule and applied to a data container during data container creation. Another example of timer-based event could be defined such that a data object (e.g., data container) expires after a given time period, as established by the owner of the data container via container access rules, has been surpassed (e.g., an hour, a week, a month, etc.). Using a timer-based self-destruct event causes a data object to expire after a set time, unless renewed (i.e., by an action during the callback or a rescheduling thereof). For example, a data container owner initially sets a timer-based self-destruct event to occur at the conclusion of a callback between the owner and a call center agent, but during the callback no resolution is made regarding the purpose of the callback and a second callback is scheduled two days out. In this example, the data container owner can manually adjust the timer-based event to expire after the conclusion of the second callback. In other implementations, the contact center agent may be granted permission from the data container owner to manually adjust the timer-based event by accessing vault manager  1310  via the agent&#39;s workstation. In other implementations, a data container owner can submit a request to renew or update an existing self-destruct event, such as a timer-based event, the request comprising a new date and/or time when the data stored in the data container is to be deleted, to vault manager  1310  configured to automatically apply the renewal or update to the timer-based event as defined in the container access rules. 
     Another type of self-destruct event that may be applied to a data container is a trigger packet event. A trigger packet event may defined such that if certain conditions are met, send notification to destroy the data container. Trigger packet events can be used defensively to provide data security in the event of unauthorized attempts to access a data container. For example, a client sends an access request (e.g., read, update, write, delete, etc.) for a data container and blockchain manager  1800  attempts to establish client identity based on stored client identification information (e.g., name, address, email address, phone number, hash, handle, username, password, etc.), but fails to find a match, so a new device identifier is obtained from the client and compared with the device identifier generated at the same time the data container was created. If, at this point, the new device identifier does not match the device identifier from creation, then the trigger packet event has occurred and the contents of the data container are destroyed. In this way, sensitive data can be protected by a dead-man&#39;s switch which only triggers in the event of unauthorized access. 
     A third type of self-destruct event that can be applied to a data container is a device-based trigger. A device-based trigger can be defined by a data container owner as a data container access rule during, or at any time after, creation of the data container. A device-based trigger may be used to delete a data container or the data contained therein based on the condition or characteristics associated with a data container owner&#39;s device (e.g., smart phone, tablet, computing device, smart wearable, PDA, etc.) For example, the device-based trigger may be proximity based wherein a data container is destroyed if a user&#39;s device enters and/or exits a specified location such as determined by a geofence. In an example, the device-based trigger may be associated with a network, wherein the data container is destroyed if the user device is connected to, or not connected to, a specified wireless network or networks. Device-based triggers may also be defined to destroy a data container if a user device is left unattended for a specified period of time. Another use case for a device-based trigger is to destroy a data container if a user device is reset. This type of device-based trigger is useful for data containers stored off-device; when a user resets their device they can be confident all associated data containers are similarly wiped. 
     The use of data container owner-defined self-destruct event triggers provides another level of added security to data containers and the transitory data stored therein. These event triggers integrate well with data containers stored in a blockchain  1811  of blockchain ledger  1810 . The data container itself is decentralized, but the lookup and decryption key can be destroyed based on a variety of conditions (e.g., self-destruct event triggers). Destruct conditions may be defined by participating parties (e.g., a callee and callback recipient), as a matter of company policy, as a standard procedure for a service provider, and/or the like. Even without any deliberate destruct trigger, a failsafe is enabled to prevent lingering accessible data that could pose a future risk. 
     According to the embodiment, self-destruct module  1820  may modify data containers and/or protected data in data containers in response to a detected self-destruction event trigger. 
     For example, self-destruction module  1820  may destroy block reference data and/or an encryption key generated by encryption and security module  1410  when protected transitory data was stored in data container. In some implementations, self-destruct module  1820  may destroy a data container and/or the data stored therein responsive to detection of a self-destruction event trigger. 
     According to the embodiment, blockchain manager  1800  is configured to receive an encrypted data container which may comprise a plurality of transitory data. The encrypted data container may be received directly from encryption and security module  1410 . In some implementations, the encrypted data container may be obtained from vault storage  1440 . In either case, the encrypted data container is received and it is stored on a node (i.e., block) on a blockchain  1811  of blockchain ledger  1810 . Using blockchain  1811  to store encrypted data containers offers protection against falsification of or tampering with a data container and/or the data contained therein. The blockchain provides an immutable record for both the storage of data and the access attempts to the data contained within. Due to the decentralized, distributed nature of the blockchain, the encrypted data container cannot be deleted from the blockchain once it has been added to the blockchain, however, all references to the encrypted data container and the keys required to decrypt it can be deleted. While this does not remove the encrypted data container from the blockchain, it does prevent the misuse and access to the encrypted data container and the transitory data stored therein. 
     According to the embodiment, for each block on blockchain  1811  which stores an encrypted data object (e.g., data container full of transitory data), blockchain manager  1800  via block reference creator  1840  can generate block reference data comprising the location of the block and the decryption key associated with the encrypted data container stored on the block. Each block within blockchain  1811  is identified by a hash, generated using a cryptographic hash algorithm (e.g., SHA256 cryptographic has algorithm) on the header of the block. Each block also references a previous block, known as the parent block, through the “previous block hash” field in the block header. In other words, each block contains the hash of its parent inside its own header. The primary identifier of a block is its cryptographic hash, a digital fingerprint, made by hashing the block header twice through the SHA256 algorithm. The resulting 32-byte hash is called the block hash and is the main identifier for a block on blockchain  1811 . The generated block reference data may indicate the location of the block by including the block hash value for the block in the block reference data. 
     Upon successfully generating block reference data for a block on blockchain  1811  comprising at least the location of the block on blockchain  1811  and the decryption key associated with the encrypted data container (synonymously referred to herein as “block decryption key”) stored in the block, the generated block reference data may be sent back to encryption and security module  1410  to encrypt the block reference data and generate a second encryption key that decrypts the block reference data. In some implementations, blockchain manager  1800  may comprise its own instance of encryption and security module  1410  and need not rely on the instance operating in vault manager  1310 . This encrypted block reference data is then stored off the blockchain in a separate database  1830 , where it can be destroyed. In some embodiments, vault storage  1440  may be used as repository for storing encrypted block reference data. In other implementations, a separate database  1830  other than vault storage  1440  may be used to store the encrypted block reference data in order to provide greater data segregation and added security. The encrypted block reference data may be destroyed based on one or more self-destruct event triggers that can be applied to the encrypted data container by the data container owner/creator and/or authorized individuals and/or entities. 
     The second encryption key may be distributed to involved parties, which allows them to decrypt and read the block reference data. To “delete” the transitory data stored in the encrypted data container, the reference block data and thus the block&#39;s decryption key are destroyed. This results in the user&#39;s (e.g., involved parties) decryption key now being useless because it only decrypts the destroyed data and contains no blockchain information of its own. In this way, the system for secure storage and management of transitory data using blockchain can provide the capability to securely store sensitive data in a blockchain structure, but still allowing for the “deletion” of the transitory data contained therein thus providing improved data security. Self-destruct event triggers can be applied such that they cause the deletion of the encrypted block reference data, thereby removing the ability of involved parties to access the block which contains the encrypted data container, effectively resulting in a deletion of the transitory data for all intents and purposes. 
     Detailed Description of Exemplary Aspects 
       FIG.  10    is a method diagram illustrating the use of a cloud callback platform for callback management, according to an embodiment. According to an embodiment, a cloud callback platform  220  must receive a request for a callback to a callback recipient, from a callback requester  1010 . This refers to an individual calling a user of a cloud callback system  220 , being unable to connect for any reason, and the system allowing the caller to request a callback, thus becoming the callback requester, from the callback recipient, the person they were initially unable to reach. A callback object is instantiated  1020 , using a callback manager  223 , which is an object with data fields representing the various parts of callback data for a callback requester and callback recipient, and any related information such as what scheduled times may be possible for such a callback to take place. Global profiles may then be retrieved  1030  using a profile manager  221  in a cloud callback system, as well as an analysis of environmental context data  1040 , allowing for the system to determine times when a callback may be possible for a callback requestor and callback recipient both  1050 . When such a time arrives, a first callback is attempted  1060  to the callback requestor or callback recipient, and if this succeeds, a second call is attempted to the second of the callback requestor and callback recipient  1070 , allowing a media server  225  to bridge the connection when both are online, before deleting the callback object  1080 . 
       FIG.  11    is a method diagram illustrating the use of a cloud callback platform for generating a context summary report from a voice call, according to an embodiment. In this embodiment, a cloud callback platform  101  must receive a client call  1105  to a business or service agent. A callback manager  155  initiates a session in response to reception of the client call  1110 . The client may select or respond to at least one call menu option  1115  before a callback is requested or a call disconnects  1120 . At that time the callback manager creates a callback object  1125  which can be used to manage, analyze, and execute callbacks between a callback requester and a callback recipient. Any available selections or responses to call menu options may be tagged as session attributes. Session attributes may be sent to and analyzed by a context analysis engine  160  which determines, generates, or derives contextual context  1130  related to the callback requester, the callback recipient, and the session attributes. The generated context content may be sent to context aggregator mechanism  175  which can generate a context summary report  1135 . The context summary report  1135  may be formatted in a variety of ways such as (but not limited to) American standard code for information interchange (“ASCII”), extensible markup language (“XML”), hypertext markup language (“HTML”), or binary format for useability with a bot or script. The callback manager  155  may obtain the context summary report and link it to the callback object  1140 . The callback manager  155  may send the context summary report, via a media server  170 , to a computing device of the callback recipient  1145 . 
       FIG.  12    is a block flow diagram illustrating an exemplary method for generating a context summary report from a text based data message session, according to an embodiment. In this embodiment, a cloud callback platform  101  must receive a text based data message  1201  from a client to a service agent. When a data message is received, a callback manager  155  may initiate a session  1202  that facilitates interactive communication between a client and service agent computing device. The callback manager may also replicate the data message  1203  and store it in a user profile managed by a profile manager  150 . Session attributes and the data message (e.g., a replication) may be sent to a context analysis engine  160  which may determine, generate, or derive contextual content. Both the context content and data message may be sent to a context aggregator  175  which merges the two components to create a context summary report  1204 . The context summary report may be sent to a service or contact center agent computing device  1205 . Next, a contact center agent may respond  1206 , in a manner informed by the context summary report, to the customer data message. At this point, the client may request a callback  1207 . If no callback is requested, but rather the client sends another data message continuing the discussion (e.g., conversation) with the contact center agent, then the process repeats itself. If, however, a callback is requested then the callback manager  155  will create a callback object  1208 , link the callback object with the session  1209 , and schedule a callback  1210 . The cloud based platform  101  may automatically send to the callback requester, a data message which contains the scheduled callback time  1211 . A client may respond  1212  to the automated data message by accepting or rejecting the scheduled callback time. A client may respond in a variety of ways such as (but not limited to) using words, emojis, characters, or even pictures. The cloud callback platform  101  may utilize the context analysis engine  160  to determine the intent of a client response to a scheduled callback time. If the client responds in a negative way, then the callback manager schedule a new callback time  1210  and another automated data message is sent to the client asking for confirmation of the revised callback time. If the client responds in an affirmative manner, then the callback manager  155  may link the context summary report to the callback object  1213  and then the cloud callback platform  101  may execute the callback at the scheduled time  1214 . 
       FIG.  15    is a flow diagram illustrating an exemplary method  1500  for managing data container interactions between a customer and an enterprise, according to an embodiment. The process begins prior to a system user placing a phone call, a personal number associated with the customer creates a container with preferences  1501 . The preferences may be used to establish the parameters of the data container. For example, preferences may include, but are not limited to, what data and data permissions may be stored in the container, how the recipient (i.e., an enterprise or company) of the container may access the data container, when and for how long the enterprise may access the data container, and who (i.e., what enterprise) may access the data container. Then the container is sent to a vault manager which encrypts the data (preferences) stored in the data container  1502 . Vault manager then stores the encrypted container in a vault database  1503 . Once the customer places the phone call and the initial conversation between customer and the enterprise occurs, the vault manager locates and retrieves the stored container for the other side of the number (i.e., the enterprise)  1504 . Vault manager may then take the combination of the two phone numbers to create a hash used as a time-bound security key password for accessing the data container  1505 . This hash key has the properties of being unique to the two callers and ephemeral as it expires in accordance with the time preferences established by the container creator. The system then links the password with the data container and stores the password in vault database  1506 . The system also generates and maintains an audit log of container activity during the initial conversation  1507 . The audit log is maintained throughout the lifetime of the data container, and tracks all interactions associated with the data container. Finally at step  1508 , the system may delete a data container at the request of the container creator or if the time preference limit has been surpassed, or the system may continue storing the vault in the database if the time limit has not been surpassed. 
       FIG.  16    is a flow diagram illustrating an exemplary method  1600  for creating a default data container, according to an embodiment. According to an embodiment, the process begins when a customer places a call or sends one or more data messages to an enterprise without creating a container with preferences and a callback may requested  1601 . A context analysis engine may generate context content data using the call data or by using the one or more data messages  1602 . Context analysis engine can parse the call or message data to determine customer intent, sentiment, and purpose for contacting the enterprise. Customer profile data may be retrieved from a database, if such data is available  1603 . Any available profile data and the context content data are sent to and received by a vault manager and used to establish default preferences and to create a default container  1604 . Additionally, vault manager may use a domain-specific database with pre-defined rules and preferences specific to the enterprise to establish default preferences. For example, context content data may indicate the customer was unhappy and calling about cancelling his service, and so a default container may be created which utilizes pre-defined enterprise rules and preferences related to customer retention. After creation, the default container is encrypted and stored in vault database  1605 . The default container is then linked to the callback object associated with the callback request of the customer  1606 . The customer may be alerted to the creation of the default container and may then access and edit the default container if necessary  1607 . The customer may be able to edit the default preferences to his or her liking. The scheduled callback is executed, the two parties are connected, and the vault manager retrieves the default container  1608 . The vault manager then combines the two phone numbers to create a hash used as a time-bound security key password for accessing default container, and the password is stored in vault database  1609 . 
       FIG.  19    is a flow diagram illustrating an exemplary method for providing secure storage and management of transitory data using blockchain, according to an embodiment. According to the embodiment, the process begins at step  1902  when blockchain manager  1800  receives an encrypted data object. The encrypted data object may be a user-created data container. The data object may comprise transitory data. The transitory data may be encrypted. The data object may be received from a database such as vault storage  1440  or it can be received from encryption and security module  1410 . At step  1904  blockchain manager  1800  stores the encrypted data object in a block of a blockchain  1811 . As a next step  1906 , reference block creator  1840  is configured to generate block reference data comprising the location of the block and its decryption key. For each block that stores an encrypted data object, reference block creator  1840  can retrieve the block hash for each block and use that as block reference data that indicates the location of the block in blockchain  1811 . In some implementations, the decryption key may be associated with the block. In some implementations, the decryption key may be associated with the encrypted data object. At step  1908 , blockchain manager  1800  and/or encryption and security module  1410  is configured to encrypt the block reference data and generate a second encryption key that decrypts the encrypted block reference data at step  1910 . 
     Blockchain manager  1800  executes step  1912  and stores the encrypted block reference data off the blockchain in a separate database, such as block reference database  1830 . At step  1914 , blockchain manager  1800  can distribute the second encryption key to involved parties. For example, in a callback use case, the involved parties may be a callee and callback recipient. The second key allows the parties to decrypt and read the block reference data which can be used to access the block which stores the encrypted data object. To “delete” the transitory data at step  1916 , the block reference data and thus the block&#39;s decryption key are destroyed. The result of this destruction is that the second key distributed to the involved parties is now useless because it only decrypts the destroyed data (i.e., reference block data) and contains no blockchain information on its own. In some implementations, step  1916  occurs when the involved parties have concluded their use of the block reference data. In other implementations, a self-destruct module  1820  is present and configured to monitor for self-destruct events and triggers, and responsive to the detection of one or more self-destruct events executes the deletion of encrypted block reference data. 
     Hardware Architecture 
     Generally, the techniques disclosed herein may be implemented on hardware or a combination of software and hardware. For example, they may be implemented in an operating system kernel, in a separate user process, in a library package bound into network applications, on a specially constructed machine, on an application-specific integrated circuit (ASIC), or on a network interface card. 
     Software/hardware hybrid implementations of at least some of the aspects disclosed herein may be implemented on a programmable network-resident machine (which should be understood to include intermittently connected network-aware machines) selectively activated or reconfigured by a computer program stored in memory. Such network devices may have multiple network interfaces that may be configured or designed to utilize different types of network communication protocols. A general architecture for some of these machines may be described herein in order to illustrate one or more exemplary means by which a given unit of functionality may be implemented. According to specific aspects, at least some of the features or functionalities of the various aspects disclosed herein may be implemented on one or more general-purpose computers associated with one or more networks, such as for example an end-user computer system, a client computer, a network server or other server system, a mobile computing device (e.g., tablet computing device, mobile phone, smartphone, laptop, or other appropriate computing device), a consumer electronic device, a music player, or any other suitable electronic device, router, switch, or other suitable device, or any combination thereof. In at least some aspects, at least some of the features or functionalities of the various aspects disclosed herein may be implemented in one or more virtualized computing environments (e.g., network computing clouds, virtual machines hosted on one or more physical computing machines, or other appropriate virtual environments). 
     Referring now to  FIG.  20   , there is shown a block diagram depicting an exemplary computing device  10  suitable for implementing at least a portion of the features or functionalities disclosed herein. Computing device  10  may be, for example, any one of the computing machines listed in the previous paragraph, or indeed any other electronic device capable of executing software- or hardware-based instructions according to one or more programs stored in memory. Computing device  10  may be configured to communicate with a plurality of other computing devices, such as clients or servers, over communications networks such as a wide area network a metropolitan area network, a local area network, a wireless network, the Internet, or any other network, using known protocols for such communication, whether wireless or wired. 
     In one aspect, computing device  10  includes one or more central processing units (CPU)  12 , one or more interfaces  15 , and one or more busses  14  (such as a peripheral component interconnect (PCI) bus). When acting under the control of appropriate software or firmware, CPU  12  may be responsible for implementing specific functions associated with the functions of a specifically configured computing device or machine. For example, in at least one aspect, a computing device  10  may be configured or designed to function as a server system utilizing CPU  12 , local memory  11  and/or remote memory  16 , and interface(s)  15 . In at least one aspect, CPU  12  may be caused to perform one or more of the different types of functions and/or operations under the control of software modules or components, which for example, may include an operating system and any appropriate applications software, drivers, and the like. 
     CPU  12  may include one or more processors  13  such as, for example, a processor from one of the Intel, ARM, Qualcomm, and AMD families of microprocessors. In some aspects, processors  13  may include specially designed hardware such as application-specific integrated circuits (ASICs), electrically erasable programmable read-only memories (EEPROMs), field-programmable gate arrays (FPGAs), and so forth, for controlling operations of computing device  10 . In a particular aspect, a local memory  11  (such as non-volatile random access memory (RAM) and/or read-only memory (ROM), including for example one or more levels of cached memory) may also form part of CPU  12 . However, there are many different ways in which memory may be coupled to system  10 . Memory  11  may be used for a variety of purposes such as, for example, caching and/or storing data, programming instructions, and the like. It should be further appreciated that CPU  12  may be one of a variety of system-on-a-chip (SOC) type hardware that may include additional hardware such as memory or graphics processing chips, such as a QUALCOMM SNAPDRAGON™ or SAMSUNG EXYNOS™ CPU as are becoming increasingly common in the art, such as for use in mobile devices or integrated devices. 
     As used herein, the term “processor” is not limited merely to those integrated circuits referred to in the art as a processor, a mobile processor, or a microprocessor, but broadly refers to a microcontroller, a microcomputer, a programmable logic controller, an application-specific integrated circuit, and any other programmable circuit. 
     In one aspect, interfaces  15  are provided as network interface cards (NICs). Generally, NICs control the sending and receiving of data packets over a computer network; other types of interfaces  15  may for example support other peripherals used with computing device  10 . Among the interfaces that may be provided are Ethernet interfaces, frame relay interfaces, cable interfaces, DSL interfaces, token ring interfaces, graphics interfaces, and the like. In addition, various types of interfaces may be provided such as, for example, universal serial bus (USB), Serial, Ethernet, FIREWIRE™, THUNDERBOLT™, PCI, parallel, radio frequency (RF), BLUETOOTH™, near-field communications (e.g., using near-field magnetics), 802.11 (WiFi), frame relay, TCP/IP, ISDN, fast Ethernet interfaces, Gigabit Ethernet interfaces, Serial ATA (SATA) or external SATA (ESATA) interfaces, high-definition multimedia interface (HDMI), digital visual interface (DVI), analog or digital audio interfaces, asynchronous transfer mode (ATM) interfaces, high-speed serial interface (HSSI) interfaces, Point of Sale (POS) interfaces, fiber data distributed interfaces (FDDIs), and the like. Generally, such interfaces  15  may include physical ports appropriate for communication with appropriate media. In some cases, they may also include an independent processor (such as a dedicated audio or video processor, as is common in the art for high-fidelity A/V hardware interfaces) and, in some instances, volatile and/or non-volatile memory (e.g., RAM). 
     Although the system shown in  FIG.  20    illustrates one specific architecture for a computing device  10  for implementing one or more of the aspects described herein, it is by no means the only device architecture on which at least a portion of the features and techniques described herein may be implemented. For example, architectures having one or any number of processors  13  may be used, and such processors  13  may be present in a single device or distributed among any number of devices. In one aspect, a single processor  13  handles communications as well as routing computations, while in other aspects a separate dedicated communications processor may be provided. In various aspects, different types of features or functionalities may be implemented in a system according to the aspect that includes a client device (such as a tablet device or smartphone running client software) and server systems (such as a server system described in more detail below). 
     Regardless of network device configuration, the system of an aspect may employ one or more memories or memory modules (such as, for example, remote memory block  16  and local memory  11 ) configured to store data, program instructions for the general-purpose network operations, or other information relating to the functionality of the aspects described herein (or any combinations of the above). Program instructions may control execution of or comprise an operating system and/or one or more applications, for example. Memory  16  or memories  11 ,  16  may also be configured to store data structures, configuration data, encryption data, historical system operations information, or any other specific or generic non-program information described herein. 
     Because such information and program instructions may be employed to implement one or more systems or methods described herein, at least some network device aspects may include nontransitory machine-readable storage media, which, for example, may be configured or designed to store program instructions, state information, and the like for performing various operations described herein. Examples of such nontransitory machine-readable storage media include, but are not limited to, magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD-ROM disks; magneto-optical media such as optical disks, and hardware devices that are specially configured to store and perform program instructions, such as read-only memory devices (ROM), flash memory (as is common in mobile devices and integrated systems), solid state drives (SSD) and “hybrid SSD” storage drives that may combine physical components of solid state and hard disk drives in a single hardware device (as are becoming increasingly common in the art with regard to personal computers), memristor memory, random access memory (RAM), and the like. It should be appreciated that such storage means may be integral and non-removable (such as RAM hardware modules that may be soldered onto a motherboard or otherwise integrated into an electronic device), or they may be removable such as swappable flash memory modules (such as “thumb drives” or other removable media designed for rapidly exchanging physical storage devices), “hot-swappable” hard disk drives or solid state drives, removable optical storage discs, or other such removable media, and that such integral and removable storage media may be utilized interchangeably. Examples of program instructions include both object code, such as may be produced by a compiler, machine code, such as may be produced by an assembler or a linker, byte code, such as may be generated by for example a JAVA™ compiler and may be executed using a Java virtual machine or equivalent, or files containing higher level code that may be executed by the computer using an interpreter (for example, scripts written in Python, Perl, Ruby, Groovy, or any other scripting language). 
     In some aspects, systems may be implemented on a standalone computing system. Referring now to  FIG.  21   , there is shown a block diagram depicting a typical exemplary architecture of one or more aspects or components thereof on a standalone computing system. Computing device  20  includes processors  21  that may run software that carry out one or more functions or applications of aspects, such as for example a client application  24 . Processors  21  may carry out computing instructions under control of an operating system  22  such as, for example, a version of MICROSOFT WINDOWS™ operating system, APPLE macOS™ or iOS™ operating systems, some variety of the Linux operating system, ANDROID™ operating system, or the like. In many cases, one or more shared services  23  may be operable in system  20 , and may be useful for providing common services to client applications  24 . Services  23  may for example be WINDOWS™ services, user-space common services in a Linux environment, or any other type of common service architecture used with operating system  21 . Input devices  28  may be of any type suitable for receiving user input, including for example a keyboard, touchscreen, microphone (for example, for voice input), mouse, touchpad, trackball, or any combination thereof. Output devices  27  may be of any type suitable for providing output to one or more users, whether remote or local to system  20 , and may include for example one or more screens for visual output, speakers, printers, or any combination thereof. Memory  25  may be random-access memory having any structure and architecture known in the art, for use by processors  21 , for example to run software. Storage devices  26  may be any magnetic, optical, mechanical, memristor, or electrical storage device for storage of data in digital form (such as those described above, referring to  FIG.  20   ). Examples of storage devices  26  include flash memory, magnetic hard drive, CD-ROM, and/or the like. 
     In some aspects, systems may be implemented on a distributed computing network, such as one having any number of clients and/or servers. Referring now to  FIG.  22   , there is shown a block diagram depicting an exemplary architecture  30  for implementing at least a portion of a system according to one aspect on a distributed computing network. According to the aspect, any number of clients  33  may be provided. Each client  33  may run software for implementing client-side portions of a system; clients may comprise a system  20  such as that illustrated in  FIG.  21   . In addition, any number of servers  32  may be provided for handling requests received from one or more clients  33 . Clients  33  and servers  32  may communicate with one another via one or more electronic networks  31 , which may be in various aspects any of the Internet, a wide area network, a mobile telephony network (such as CDMA or GSM cellular networks), a wireless network (such as WiFi, WiMAX, LTE, and so forth), or a local area network (or indeed any network topology known in the art; the aspect does not prefer any one network topology over any other). Networks  31  may be implemented using any known network protocols, including for example wired and/or wireless protocols. 
     In addition, in some aspects, servers  32  may call external services  37  when needed to obtain additional information, or to refer to additional data concerning a particular call. Communications with external services  37  may take place, for example, via one or more networks  31 . In various aspects, external services  37  may comprise web-enabled services or functionality related to or installed on the hardware device itself. For example, in one aspect where client applications  24  are implemented on a smartphone or other electronic device, client applications  24  may obtain information stored in a server system  32  in the cloud or on an external service  37  deployed on one or more of a particular enterprise&#39;s or user&#39;s premises. In addition to local storage on servers  32 , remote storage  38  may be accessible through the network(s)  31 . 
     In some aspects, clients  33  or servers  32  (or both) may make use of one or more specialized services or appliances that may be deployed locally or remotely across one or more networks  31 . For example, one or more databases  34  in either local or remote storage  38  may be used or referred to by one or more aspects. It should be understood by one having ordinary skill in the art that databases in storage  34  may be arranged in a wide variety of architectures and using a wide variety of data access and manipulation means. For example, in various aspects one or more databases in storage  34  may comprise a relational database system using a structured query language (SQL), while others may comprise an alternative data storage technology such as those referred to in the art as “NoSQL” (for example, HADOOP CASSANDRA™, GOOGLE BIGTABLE™, and so forth). In some aspects, variant database architectures such as column-oriented databases, in-memory databases, clustered databases, distributed databases, or even flat file data repositories may be used according to the aspect. It will be appreciated by one having ordinary skill in the art that any combination of known or future database technologies may be used as appropriate, unless a specific database technology or a specific arrangement of components is specified for a particular aspect described herein. Moreover, it should be appreciated that the term “database” as used herein may refer to a physical database machine, a cluster of machines acting as a single database system, or a logical database within an overall database management system. Unless a specific meaning is specified for a given use of the term “database”, it should be construed to mean any of these senses of the word, all of which are understood as a plain meaning of the term “database” by those having ordinary skill in the art. 
     Similarly, some aspects may make use of one or more security systems  36  and configuration systems  35 . Security and configuration management are common information technology (IT) and web functions, and some amount of each are generally associated with any IT or web systems. It should be understood by one having ordinary skill in the art that any configuration or security subsystems known in the art now or in the future may be used in conjunction with aspects without limitation, unless a specific security  36  or configuration system  35  or approach is specifically required by the description of any specific aspect. 
       FIG.  23    shows an exemplary overview of a computer system  40  as may be used in any of the various locations throughout the system. It is exemplary of any computer that may execute code to process data. Various modifications and changes may be made to computer system  40  without departing from the broader scope of the system and method disclosed herein. Central processor unit (CPU)  41  is connected to bus  42 , to which bus is also connected memory  43 , nonvolatile memory  44 , display  47 , input/output (I/O) unit  48 , and network interface card (NIC)  53 . I/O unit  48  may, typically, be connected to peripherals such as a keyboard  49 , pointing device  50 , hard disk  52 , real-time clock  51 , a camera  57 , and other peripheral devices. NIC  53  connects to network  54 , which may be the Internet or a local network, which local network may or may not have connections to the Internet. The system may be connected to other computing devices through the network via a router  55 , wireless local area network  56 , or any other network connection. Also shown as part of system  40  is power supply unit  45  connected, in this example, to a main alternating current (AC) supply  46 . Not shown are batteries that could be present, and many other devices and modifications that are well known but are not applicable to the specific novel functions of the current system and method disclosed herein. It should be appreciated that some or all components illustrated may be combined, such as in various integrated applications, for example Qualcomm or Samsung system-on-a-chip (SOC) devices, or whenever it may be appropriate to combine multiple capabilities or functions into a single hardware device (for instance, in mobile devices such as smartphones, video game consoles, in-vehicle computer systems such as navigation or multimedia systems in automobiles, or other integrated hardware devices). 
     In various aspects, functionality for implementing systems or methods of various aspects may be distributed among any number of client and/or server components. For example, various software modules may be implemented for performing various functions in connection with the system of any particular aspect, and such modules may be variously implemented to run on server and/or client components. 
     The skilled person will be aware of a range of possible modifications of the various aspects described above. Accordingly, the present invention is defined by the claims and their equivalents.
