Abstract:
A request to obtain data items associated with an entity is received from a client device. One or more computing devices determine whether access to the data items is restricted by an access control policy and whether the client device complies with the access control policy. In response to determining that the client device complies with the access control policy, at least a portion of the data items that the access control policy permits the client device to access are identified. An integration of the at least a portion of the data items with additional data items is initiated.

Description:
BACKGROUND 
     Data access sharing provides configurable permissions to share items between data sets associated with the same entity. In some situations, a single entity, such as a work team or an individual user, may want to share event items between the data sets of different calendars. For example, a user may have a personal calendar with private appointments, birthdays, vacation details, etc. as well as a work calendar with meetings, office holidays, and deadlines. Conventional approaches generally require the user to manually copy items from one calendar to the other or use a synchronization application that simply duplicates all items from one calendar to the other. This creates security and privacy problems, as the user may not wish for a personal appointment, such as a doctor&#39;s visit, to be visible on their work calendars. Similarly, a business may not want details of their employees confidential meetings visible on a personal calendar that may then be shared with non-employees of the business.

     DETAILED DESCRIPTION 
     The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments of the disclosure may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the disclosure. Instead, the proper scope of the disclosure is defined by the appended claims. 
     Shared data access may be provided. Often, a person may use multiple devices and/or applications to keep track of data such as contact lists, calendars, to-do items, document files, email/SMS messages, and the like. For example, they may have an enterprise calendar associated with their work that may be stored and managed on their company&#39;s servers as well as a personal calendar, such as may be offered with their personal email or Internet Service Provider (ISP). In some situations, multiple users may be part of a group, such as a team within the company, that may have shared data sets for tracking project progress, deadlines, status meetings, etc. 
     Using a calendar application as a non-limiting example, a user&#39;s enterprise calendar may be encrypted to protect confidential data, such as contact names, meeting subjects, agendas, etc. In some cases, however, at least some of the enterprise calendar data may need to be shared to the personal calendar, such as for the user&#39;s convenience in viewing a single calendar application with all of their event data. The enterprise calendar data may be analyzed to identify those properties that may not need to be kept confidential and may be shared, such as the existence of an event, its start/end time, and/or a status (e.g., free, busy, out of office, tentatively busy, etc.) associated with the event. The non-confidential data may then be published so that a single calendar view can display a user&#39;s personal events and at least some information associated with the enterprise events. In some embodiments publication and/or propagation of the data may comprise exporting the data to an external location, such as a web-server, to another application, and/or copying the data to another memory location in a device. 
     In some embodiments, a user may not want their personal calendar data shared with other employees of their company or enterprise and/or the enterprise may wish to protect the user&#39;s privacy by restricting the enterprise&#39;s access to the personal data. The user may still desire to let those other employees know their availability, however. Similar non-confidential information from the user&#39;s personal calendar may be collected and published so that the user&#39;s enterprise calendar can reflect the limited, non-confidential information. 
     Publication of the non-confidential information from one calendar to another may be accomplished in several ways. In some embodiments, one calendar application may subscribe to a service that receives and publishes the non-confidential information from another calendar. Such a subscription may require authentication for a given entity (e.g., another user, an enterprise server, and/or an application) to access even the non-confidential information, such as where a user may provide a Personal Identification Number (PIN), password, or similar token to allow only those other entities the user has approved to access the event information. 
     In some embodiments, two calendar data sets may be maintained on a single device, with one data set contained within a “sandbox” environment that is generally unaccessible to applications and/or hardware components that are not authorized to operate within the sandbox. For example, all enterprise data may be required to be encrypted unless opened in a sandboxed application that does not allow the export of data within that application. The calendar data within the sandbox may be analyzed and a subset of the data that does not contain confidential data may be published to a shared storage area of the device. 
     In some embodiments, event data may be shared between enterprise calendars of two users associated with the enterprise. For example, a single calendar view may display status information for several members of a team without displaying confidential and/or personal/private information associated with the underlying events.

The capture device may comprise any speech and/or motion detection device capable of detecting the speech and/or actions of the user(s). 
     Data generated by applications may be stored in memory  110  by the processor  105  during the course of application program execution. Data may be provided to the user during application program execution by means of a display  130 . Consistent with embodiments of this disclosure, display  130  may comprise an integrated display screen and/or an output port coupled to an external display screen. 
     Memory  110  may also comprise a platform library  140 . Platform library  140  may comprise a collection of functionality useful to multiple applications, such as may be provided by an application programming interface (API) to a software development kit (SDK). These utilities may be accessed by applications as necessary so that each application does not have to contain these utilities thus allowing for memory consumption savings and a consistent user interface. 
     Furthermore, embodiments of this disclosure may be practiced in conjunction with a graphics library, other operating systems, or any other application program and is not limited to any particular application or system. The devices described with respect to the Figures may have additional features or functionality. For example, user device  100  may also include additional data storage devices (removable and/or non-removable) such as, for example, magnetic disks, optical disks, or tape (not shown). 
     User device  100  may store device and/or user-specific information in a data store  150 , such as a device profile and/or a plurality of user preferences. A device profile may comprise an indication of the current position of user device  100  and/or indications of the hardware, software, and security attributes which describe user device  100 . For instance, the device profile may represent hardware specifications of user device  100 , version and configuration information of various software program and hardware components installed on user device  100 , data transmission protocols enabled on user device  100 , version and usage information of various resources stored on user device  100 , and/or any other attributes associated with the state of user device  100 . The device profile may further comprise data indicating a date of last virus scan of user device  100 , a date of last access by an IT representative, a date of last service by the IT representative, and/or any other data indicating maintenance and usage of user device  100 . Furthermore, the device profile may comprise indications of the past behavior of associated users, such as resources accessed, charges for resource accesses, and the inventory accessed from such resources. The user preferences may comprise a listing of factors that may affect the experience of the user. In particular, the user preferences may include indications of the user&#39;s age, gender, bodily traits, preferred resource types, preferred venue resources, and combinations thereof. 
       FIG. 2  is a block diagram view of an operating environment  200  comprising user device  100  coupled to a web server  210  and an enterprise server  220  via a network  230 . The web server  210  and enterprise server  220  may comprise, for example, server computers or any other system providing distribution capability. For purposes of convenience, the web server  210  and enterprise server  220  are referred to herein in the singular, although it is understood that a plurality of servers may be employed in the arrangements as descried herein. Furthermore, in some embodiments, web server  210  and enterprise server  220  may operate on the same server computer. 
     The components executed on the web server  210  and/or the enterprise server  220 , for example, may comprise a synchronization service  225  and a calendar service  230  as well as other applications, services, processes, systems, engines, or functionality not disclosed in detail herein. The synchronization service  225  may be executed to publish calendar information from calendar service  230  and/or receive information from a calendar app  235  executing on user device  100 . The synchronization service  225  may also be operable to manage subscription requests for calendar information associated with calendar service  230  and/or calendar app  235 . In some embodiments, the web server  210  may execute a proxy service  227  between user device  100  and enterprise server  220 . As used herein, the term “proxy service” is meant to generally refer to computer-executable instructions for authenticating user access credentials and device identifiers. The proxy service  227  may execute to receive an access request from the user device  110  for accessing enterprise resources such as the calendar service  230  and to determine whether to grant or deny the access request. Upon determining to grant the access request, the proxy service  227  may then associate the user device  100  with necessary enterprise access credentials to access the enterprise resources. The web server  210  and enterprise server  220  may include other applications, services, processes, systems, engines, or functionality not discussed in detail herein. 
     The network  230  may comprise, for example, any type of wired and/or wireless network such as a wireless local area network (WLAN), a wireless wide area network (WWAN), Ethernet, fiber-optic network, and/or any other type of wired and/or wireless network now known or later developed. Additionally, the network  110  may be or include the Internet, intranets, extranets, microwave networks, satellite communications, cellular systems, PCS, infrared communications, global area networks, or other suitable networks, etc., or any combination of such networks. 
       FIG. 3  is a flow chart setting forth the general stages involved in a method  300  consistent with embodiments of this disclosure for providing data access sharing. Ways to implement the stages of method  300  will be described in greater detail below. For purposes of illustration, not limitation, method  300  is described with respect to user device  100  in communication with web server  210 . Method  300  may begin at starting block  305  and proceed to stage  310  where web server  210  may receive a request for a list of data items. For example, calendar app  235  may be executed on user device  100  and may request a plurality of calendar information that may be saved in data store  150  and/or may be provided by calendar service  230  via synchronization service  225 . 
     From stage  310 , method  300  may advance to stage  320  where web server  210  may determine whether access to the requested data items is controlled. For example, an access control policy associated with calendar service  230  may require authentication before providing calendar data to web server  210  and/or user device  100 . Access control policies may include device, user, location, and or time/date restrictions that must be satisfied before access is permitted. For another example, calendar app  235  may execute in a controlled environment that may need to decrypt stored information before display. In some embodiments, calendar information in data store  150  may comprise personal event information associated with a user of user device  100  and calendar information provided by calendar service  230  may comprise enterprise event information. The enterprise event information may be associated with a user of user device  100 , people other than the user of user device  100  (e.g., co-workers), and/or may be associated with non-person entities, such as a company, a product, or a working group. 
     If the access to the requested calendar data is controlled, method  300  may advance to stage  325  where web server  210  may determine whether the request is authorized. For example, user device  100  may submit user and/or device credentials to an authentication subroutine of calendar app  235  and/or may perform an authentication with web server  210  and/or enterprise server  220 . Furthermore, the device characteristics of the user device  100  may be evaluated for compliance with a plurality of compliance rules. For example, a compliance service, that may be executed on any of the elements of operating environment  200 , may identify the device characteristics from the device profile and compare them to a listing of hardware restrictions, software restrictions, and/or mobile device management restrictions that need to be satisfied by the user device  100 . 
     The user credentials may uniquely identify the user of the user device  100 . For example, the user credentials may include a username, a password, a token, and/or biometric data related to facial recognition, retina recognition, fingerprint recognition, and the like. User credentials may be input by a user via any suitable client side application and may be stored in the data store  150  of the user device  100 . Accordingly, user credentials may be retrieved from the data store  150  and/or may be input by a user in connection with a request for access to the calendar data. Device credentials may also be used to authenticate the request for information, separately and/or in combination with the user credentials. For example. the device credentials may comprise a unique identifier and/or a device profile comprising data such as a date of last virus scan, a date of last access by IT, a date of last tune-up by IT, and/or any other data indicating a date of last device check. If the request is determined not to be authorized, method  300  may end at stage  355 . 
     If the request is determined to be authorized at stage  325 , method  300  may advance to stage  330 , where web server  210  may identify data information that may be accessed. For example, the authorization of user device  100  may prohibit the display of details associated with the requested calendar information. In such a case, synchronization service  225  and/or calendar service  230  may examine each event in the enterprise calendar information and remove or modify any private, confidential and/or restricted properties. In some embodiments, the requested calendar information may be used to generate a new set of calendar information comprising a limited subset of properties of the events in the requested calendar information, such as start and end times, dates, and/or statuses such as free, busy, out-of-office, tentatively busy, etc. For another example, synchronization service  225  may determine that none of an enterprise contact list may be propagated outside of the enterprise environment, regardless of a user&#39;s authorization. 
     After identifying the data information at stage  330 , method  300  may advance to stage  340  where web server  210  may publish the identified data information. For example, synchronization service  225  may create a data file of the limited subset of event properties that may be accessed by user device  100 . For another example, web server  210  may allow the publication of a list of messages (e.g, e-mail, voicemail, and/or SMS messages) received and who they are from, without permitting access to the content of those messages. 
     Method  300  may then advance to stage  350  where user device  100  may integrate the requested calendar information. For example, calendar app  235  may integrate personal calendar data with the published event information into a single view. Examples of such a view are described below with respect to  FIGS. 4A-4D . Method  300  may then end at stage  355 . 
       FIG. 4A  illustrates a first user interface  400  displaying a plurality of personal calendar events. For example, a doctor&#39;s appointment event  402  and a birthday event  404  may be displayed on first user interface  400 . 
       FIG. 4B  illustrates a second user interface  410  displaying a plurality of enterprise calendar events. For example, a product meeting event  412 , a teleconference event  414 , and a vacation event  416  may be displayed on second user interface  410 . 
       FIG. 4C  illustrates a third user interface  420  displaying the plurality of personal calendar events  402 ,  404  integrated with a limited subset of information from the plurality of enterprise calendar events  412 ,  414 ,  416 . For example, enterprise events  412  and  414  are displayed as events  422 (A)-(B) showing that the user is busy without displaying any further details of the events. Vacation event  416  may be recognized as comprising non-restricted information, and so may be displayed with all of its respective properties. 
       FIG. 4D  illustrates a fourth user interface  430  displaying the plurality of enterprise calendar events  412 ,  414 , and  416  integrated with a limited subset of information from the plurality of personal calendar events  402 ,  404 . Such a view may be available, for example, on an enterprise view of a user&#39;s calendar. In fourth user interface  430 , enterprise events  412 ,  414 , and  416  are displayed with their full information while personal event  402  is redacted to show a busy event  432 . Birthday event  404  may be recognized and/or explicitly marked in a property as a public event, and so its full properties may be displayed.
