Title: Security in a communication network

Description:
BACKGROUND 
     The present invention relates generally to cyber security and, in particular, to security maximization for a computer related device based on real-time reaction. 
     Cyber hacking is a widely known and prevalent problem. Many schemes have been tried to prevent or ameliorate the problem. These normally revolve around authenticating a user or building a firewall or setting permissions. These defensive measures have been useful but are limited. 
     SUMMARY 
     A computer-implemented method, system, and/or computer program product provides security in a communication network between a user device and a computer related device, and receives payment for services offered through a distributed registry associated with the communication network. One or more processors provide a distributed registry that specifies a plurality of services available to support communications between a user device and a computer related device on a communication network. The processor(s) dynamically construct one or more multi-node transient processing pathways between the user device and the computer related device based on a first service from the plurality of services. The processor(s) dynamically adjust the one or more multi-node transient processing pathways between the user device and the computer related device based on a second service from the plurality of services. For at least one node in each of the one or more transient processing pathways, an address thereof and a time period that the at least one node is active and capable of being used is adjusted based on at least one of an application programming interface type and a data request type implicated by a received packet by the user device. The processor(s) present the plurality of services specified by the distributed registry to the user device, and append metadata describing a current cryptocurrency cost of each of the plurality of services to a description of said each of the plurality of services. In response to receiving a request from the user device for a particular service from the plurality of services, the processor(s) charge the current cryptocurrency cost to a cryptocurrency account associated with the user device and provide the particular service to the user device. 
     These and other features and advantages will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings.

     DETAILED DESCRIPTION 
     The present principles are directed to security maximization for a computer related device based on real-time reaction. In particular, the security maximization is provided between a user device and the computer related device. The computer related device can be a computer or computer system of any form (e.g., including, but not limited to computer-based transaction systems, and so forth) or a device related to a computer or computer system (e.g., any peripheral including, but not limited to, a router, a modem, a database, a printer, a scanner, a biometric device, an input device, and so forth). 
     In an embodiment, the present principles relate to an application of the Distributed Autonomous Corporation (DAC) concept to general-purpose cloud computing, including one-way or two-way anonymization using one or more proxies similarly to Tor or I2P. The integrated anonymization function can have one or multiple layers of anonymization. By implementing a distributed cloud computing infrastructure as a DAC with robust integrated anonymity for both service requesters and service providers an assurance of privacy is provided that is impossible to obtain in current cloud computing systems. 
     In an embodiment, the present principles provide a system and method that are highly responsive and resistive to probabilistic threat levels in a highly variable manner based on risk value. 
     In an embodiment, the present principles maximize the security for a computer related device based on real-time reaction to a dynamically computed probabilistic threat security assessment utilizing multi-layered virtual machine engines that are dynamically configured into a highly dynamic, occulted, topology of processing lanes. 
     In an embodiment, the present principles can reduce the probability of a successful attack on a computer related device using a real-time risk sensitive system that dynamically alters a multi-node processing pathway between the user and the computer related device. The nodes are composed of virtual machines (VMs) in a highly variable topology. These virtual machines must be addressed in the proper sequence, at the proper address, using the correct encryption code and during the right time window (when the relevant nodes are active). Normally only the entrance VM is in existence and visible. The other nodes are instantiated only as needed by an out-of-plane control node. Depending upon the risk level, different processing lanes are constructed for each function required to interact with data (e.g., functions including, but not limited to, issuing a command, viewing a return set, and so forth). The topology of the lanes and nodes is re-phased on a quasi-random scheme. This mechanism is highly resistant to picking because of the defense in depth that requires multiple dimensions of precision to successfully interact with the transaction system or the data. Getting anything in the wrong order, or at the wrong address or with the wrong key will be totally successful in preventing an attack. Moreover, any partial pick will provide no advantage for a future attack. 
       FIG.  1    shows an exemplary processing system  100  to which the present principles may be applied, in accordance with an embodiment of the present principles. The processing system  100  includes at least one processor (CPU)  104  operatively coupled to other components via a system bus  102 .

Of course, other types of input devices can also be used, while maintaining the spirit of the present principles. The user input devices  152 ,  154 , and  156  can be the same type of user input device or different types of user input devices. The user input devices  152 ,  154 , and  156  are used to input and output information to and from system  100 . 
     Of course, the processing system  100  may also include other elements (not shown), as readily contemplated by one of skill in the art, as well as omit certain elements. For example, various other input devices and/or output devices can be included in processing system  100 , depending upon the particular implementation of the same, as readily understood by one of ordinary skill in the art. For example, various types of wireless and/or wired input and/or output devices can be used. Moreover, additional processors, controllers, memories, and so forth, in various configurations can also be utilized as readily appreciated by one of ordinary skill in the art. These and other variations of the processing system  100  are readily contemplated by one of ordinary skill in the art given the teachings of the present principles provided herein. 
     Moreover, it is to be appreciated that systems  200  and  300  described below with respect to  FIG.  2    and  FIG.  3    are systems for implementing respective embodiments of the present principles. Part or all of processing system  100  may be implemented in one or more of the elements of system  200  and/or in one or more of the elements of system  300 .

Similarly, part or all of system  200  and/or part or all of system  300  may be used to perform at least part of method  400  of  FIG.  4   . 
     It is to be appreciated that there can be some overlap between the elements of system  200  and system  300 . As such, descriptions of various aspects of various elements of one system while not explicitly mentioned with respect to the other system for the sake of brevity, can also apply to various aspects of various elements of the other system while maintaining the spirit of the present principles. 
       FIG.  2    shows an exemplary system  200  for security maximization for a computer related device, in accordance with an embodiment of the present principles. 
     For illustrative purposes, the example of  FIG.  2    can be considered to apply and/or otherwise represent a secure work location at predicted hours. Of course, the present principles in general and system  200  in particular can be applied to other situations while maintaining the spirit of the present principles. 
     The system  200  is used to maximize the security between a user workstation  291  and a database  292 . The user workstation  291  hosts browser sessions sent back by each function in a chain of functions. 
     The system  200  includes and/or otherwise involves a management node  210 , a distributed registry  220 , and a set of workload virtual machines (VMs)  230 . While the embodiment of  FIG.  2    includes only one each of the preceding elements  210  and  220 , it is to be appreciated that other embodiments of the present principles can include more than one of any of the preceding elements  210  and  220 . 
     The management node  210  specifies one or more processing paths based on risk. In an embodiment, the management node  210  configures the set of VMs  230  to form one or more multi-node processing paths (lanes) based on risk. Further details regarding the configuring of the set of VMs is described below. 
     The management node  210  also performs risk assessment where, as noted above, such risk assessment is used to specify one or more processing paths. This risk assessment is described in further detail herein below. 
     The distributed registry  220  includes encrypted and/or algorithmically occluded pointers to the set of workload VMs  230 . In an embodiment, the distributed registry  220  can be implemented as a distributed hash table. Other forms are also possible for the distributed registry  220 , while maintaining the spirit of the present principles. 
     The set of workload VMs  230  form the nodes of a multi-node processing pathway(s) between the user workstation  291  and the database  292 . In an embodiment, one or more of the workload VMs  230  form a respective node of a respective multi-node processing pathway. The VMs  230  are described in further detail herein below. 
       FIG.  3    shows another exemplary system  300  for security maximization for a computer related device, in accordance with an embodiment of the present principles. 
     For illustrative purposes, the example of  FIG.  3    can be considered to apply and/or otherwise represent a problematic location in a problematic country outside of predicted hours. Thus, the example of  FIG.  3    can also be considered to represent a highly insecure example, in contrast to the example of  FIG.  2    which is presumably somewhat more secure. Of course, the present principles in general and system  300  in particular can be applied to other situations while maintaining the spirit of the present principles. 
     The system  300  is used to maximize the security between a user workstation  391  and a distributed database  392 . The user workstation  391  hosts browser sessions sent back by each function in a chain of functions. The distributed database  392  represents a set of services that can include, but are not limited to, relational or noSQL database services and/or other storage and/or state maintenance functions, and which overlap with the workload virtual machines  330 . 
     The system  300  includes and/or otherwise involves a set of management nodes  310 , a set of distributed registries  320 , a set of workload virtual machines  330 , a set of one-way or two-way anonymizing proxies to workload VMs  340 , multiple layers of indirection  350 , and a set of out-of-band alarm and control systems  360 . 
     The set of management nodes  310  specifies one or more processing paths based on risk. In an embodiment, the set of management nodes  310  configure the set of VMs  330  and the set of one-way or two-way anonymizing proxies to workload VMs  340  to form one or more multi-node processing paths (lanes) based on risk. Further details regarding the configuring of the set of VMs is described below. 
     The set of management nodes  310  also perform risk assessment where, as noted above, such risk assessment is used to specify one or more processing paths. This risk assessment is described in further detail herein below. 
     In an embodiment, the set of management nodes  310  are implemented as a distributed set. 
     The set of distributed registries  320  include encrypted and/or algorithmically occluded pointers. For example, in an embodiment, the set of distributed registries  320  can be based on a cryptographic block chain, as various cryptocurrencies are today. In an embodiment, one or more of the distributed registries in the set can be implemented as a distributed hash table. Other forms are also possible for any of the distributed registries  320 , while maintaining the spirit of the present principles. 
     Once the set of management nodes  310  is established, their primary function is to establish a globally distributed service registry. Any nodes attaching to the network may advertise a service, and the availability of this service is advertised to the rest of the network. In an embodiment, the service availability is advertised in a similar way to the BitTorrent network propagating the availability of a file. In an embodiment, services are standardized using a system of common service codes; version numbers can be standardized, and management nodes can opt not to accept unknown service codes or service codes below a version number. The registry service itself may also be advertised between nodes with a version number, subject to these same optional limitations. 
     A distributed registry service, operated across the distributed network of management nodes, is the function that enables the proxy service, the various hosting services for workload virtual machines, and the database services to be advertised to anyone attaching to the network. Anyone connecting to the network via a management mode can advertise a service or request a service of a node that has advertised one. 
     Service advertisements, requests for service, and completed transactions can optionally be logged as a transaction in the distributed registry. 
     The set of workload VMs  330  form at least some of the nodes of a multi-node processing pathway(s) between the user workstation  391  and the database  392 . In an embodiment, one or more of the workload VMs  330  form a respective node of a respective multi-node processing pathway. The VMs  230  are described in further detail herein below. 
     The one-way or two-way anonymizing proxies to workload VMs  340  provide one-way or two-way anonymity regarding communications between the user workstation  391  and a distributed database  392 . 
     The one-way or two-way anonymizing proxies to workload VMs  340  provide a second general service, which is advertised on the distributed registry and propagated through the network composed of management nodes as a proxy service for the purpose of anonymization. In an embodiment, this service can be implemented to be directly comparable to Tor and I2P and can optionally make use of these existing networks. However, the proxy service is intended to allow one way or two-way anonymity and is integrated with the registry service such that all services may be registered either anonymously or in the clear or both. Likewise, all services may be requested and transactions brokered through the network either anonymously or in the clear. Finally, all advertisements, requests, and transactions may be required to go through one or more layers of anonymization for greater privacy and security. 
     The multiple layers of indirection  350  can be used when routing communications between the user workstation  391 , the workload VMs  330 , and the distributed database  392  through the set of one-way or two-way anonymizing proxies to workload VMs  340 . In this way, subsequent hops through the nodes are made difficult to predict. 
     The set of out-of-band alarm and control systems  360  provide additional security for the communications between the user workstation  391 , actual workload virtual machine  330 , and distributed database  392 . 
     In order to provide security for the control of virtual machines being run on actual hardware, all control signals and system commands can use cryptography to prevent their interception by outsiders. Additionally using a separate communications network for the commands separate from anonymized communication flows (as per the one-way or two-way anonymizing proxies to workload VMs  340 ) will make interception and decryption significantly more difficult. All control, allocation, de-allocation, movement of running virtual machines, and security messages will be sent to different IP addresses, well-known port numbers, utilizing encrypted communications. The present principles are not limited to any particular encryption technology or protocol. Thus, any encryption technology and protocol as applicable can be used in accordance with the teachings of the present principles, while maintaining the spirit of the present principles. By utilizing different and shifting IP addresses, independent of communications related to the distributed workload, determinations of which message went to which actual physical hardware will increase the difficulty of interception many fold. It is also possible to provide an independent communications network for out-of-band control communications. This could include, for example, but is not limited to, physical communication means such as light fiber, a local area network not connected to the Internet, or physical traces on motherboards. 
     If penetration attempts are detected, the control system can order the anonymizing proxies to issue all new communications to altered IP addresses and well-known port numbers. Ideally, the out-of-band alarm and control system  360  would run on different hardware than the anonymizing proxies  340 . Upon receiving notifications from the out-of-band alarm and control system  360  that penetration attempts have been detected, commands will be sent to anonymizing proxies  340  with new IP addresses and well-known port numbers generated by the out-of-band alarm and control system  360 . The anonymizing proxies  340  will not be informed why addresses are being changed, only that they must to do so immediately. Detection of penetration attempts may be determined by out of band alarm and control systems or other external security or network monitoring programs. 
     Out-of-band alarm and control system  360  will only know virtual IP addresses and not physical IP addresses. This has two major advantages. One advantage is that it eases the difficulties of configuring a zero knowledge network. Another advantage is that it provides a level of security when actual physical IP addresses are not known by the anonymizing proxies  340  nor the out-of-band alarm and control system  360 . 
       FIG.  4    shows an exemplary method  400  for security maximization for a computer related device, in accordance with an embodiment of the present principles. 
     At step  410 , receive, from one or more service providers, respective specifications of respective services provided by the one or more service providers to support communications over one or more multi-node transient processing pathways between the user device and the computer related device. The services can include, but are not limited to, one-way and/or two-way anonymizing proxy services, indirection services, workload virtual machines services, out-of-band control communication services, and so forth. 
     At step  420 , provide, for one or more users, a distributed registry service that specifies a set of services available to support communications between the user device and the computer related device. The set of services can include one or more services whose respective specifications were received in step  410 . In an embodiment, the set of services or a selection of at least some of the services can be determined based on, for example, a probabilistic threat assessment of potential threats against the computer related device. In an embodiment, the probabilistic threat assessment indicates a respective threat level. 
     At step  430 , dynamically construct one or more multi-node processing pathways between the user device and the computer related device based on selected ones of the services in the set. For example, a user may select various services from the set of services based on the user&#39;s needs, an expected threat, and so forth. 
     In an embodiment, each of the one or more multi-node processing pathways includes a beginning node, an end node, and a set of intervening nodes. In an embodiment, at least the set of intervening nodes are instantiated on demand by an out-of-plane control node (e.g., a management node) and, thus, may last for varying lengths of time. In an embodiment, only the beginning node is normally in existence and externally visible. 
     The nodes of each of the one or more processing paths are configured to have a highly variable topology, and must be addressed in the proper sequence, at the proper address, using the correct encryption code, and during the right time window (when the relevant nodes are active). In an embodiment, the topology of the nodes and the corresponding processing paths that they form are re-phased on a quasi-random scheme. In an embodiment, each node of the one or more multi-node processing pathways includes a portion for receiving directions from a user or preceding nodes or an out-of-band alarm and control system, a firewall portion, and at least one portion for directing subsequent nodes and/or actions. 
     In an embodiment, the one or more multi-node processing pathways are constructed to include one or more sets of virtual machines (e.g., workload VMs and/or one-or-two-way anonomizing proxies to workload VMs) with a variable topology. 
     In an embodiment, step  430  can involve constructing a respective multi-node processing pathway for each respective function from a set of functions required to interact with data, based on a risk level indicated by the probabilistic threat assessment. 
     In an embodiment, each of the one or more multi-node processing pathways is constructed to have a different topology that is based on which of a plurality of different types of application programming interface calls are invoked for a current session between the user device and the computer related device. 
     In an embodiment, proxies can be used in the one or more multi-node processing pathways. 
     At step  440 , dynamically alter one or more multi-node processing pathways between the user device and the computer related device based on selected ones of the services in the set. In an embodiment, step  440  can involve changing, for at least one node in a processing pathway(s), an address (e.g., an Internet Protocol (IP) address and/or a media access control (MAC) address) thereof and a time period the at least one node is active and capable of being used, based on an application programming interface type and/or a data request type (e.g., implicated by a received packet). 
     In an embodiment, each of the one or more multi-node processing pathways is altered more frequently based on increasing threat level and is altered less frequently based on decreasing threat level. In an embodiment, a node topology of each of the one or more multi-node processing pathways is re-phased on a quasi-random scheme. 
     In an embodiment, step  440  can involve changing address and port numbers of nodes that are uncalled in at least a given one of the one or more multi-node processing pathways in response to calling a particular address and a particular port number in the given one of the one or more multi-node processing pathways. 
     In an embodiment, each of the one or more multi-node processing pathways is altered to have a different topology that is based on which of a plurality of different types of application programming interface calls are invoked for a current session between the user device and the computer related device. 
     In an embodiment, multiple layers of indirection can be implemented in the communications between the user workstation and the distributed database. 
     In an embodiment, encryption keys and/or types of encryption keys can be varied for one or more of the nodes in the one or more multi-node processing pathways. 
     In an embodiment, proxies can be used in the one or more multi-node processing pathways. 
     A description will now be given regarding various advantages and exemplary implementations of the present principles. 
     Advantageously, the present principles dynamically provide the necessary level of security based on probabilistic risks and processing activity. The response level consumes resources in an optimized manner proportional to the threat(s). Above the lowest level of threat, the topology of the system is highly dynamic and highly variable with an ultra-low level of repeated patterning. In an embodiment, a low threat environment can have a logical path of, for example, two nodes. In an embodiment, a high level threat can have a path of, for example, twenty or more nodes with only one visible known point (node). It is to be appreciated that the preceding numbers of nodes are merely illustrative and, thus, other numbers of nodes may be used in accordance with the teachings of the present principles, while maintaining the spirit of the present principles. In an embodiment, processing paths expand on a horizontal plane (conceptually) according to plans that are spread across multiple platforms, at multiple different addresses, for variable lengths of time. 
     In an embodiment, the present principles can provide a unique topology of changing IP addresses and port numbers for each different type of application programming interface (API) call and data request. When a new IP packet arrives at a correct IP address, the packet is analyzed to determine what API call, database request, analytic algorithm, source data systems to fulfill a federated database query, or executable program is being requested. Guessing IP addresses and port numbers would be insufficient to hack into the protected device or communication between the user and the protected device. Also, calling one of the specific IP address and port numbers would cause all the other IP addresses and port numbers, which were not called, to also change. By adding a topology for each type of call, the present principles advantageously provide a significant advancement over the current state of the art. 
     A description will now be given regarding defining a threat level, in accordance with an embodiment of the present principles. 
     The threat level is determined based on, for example, an N dimensional, nonlinear threat matrix. Factors can include, but are not limited to, one or more the following: CRUD activity (Create, Read, Update, Delete); volume; element/transaction sensitivity; known secure location versus known insecure location; are you where your calendar says you will be (e.g., agreement there between lowers the risk level, while disagreement there between raises the risk level); personal/cohort known pattern agreement; and so forth. It is to be appreciated that the preceding factors for determining threat level are merely illustrative and, thus, other factors can also be used in accordance with the teachings of the present principles, while maintaining the spirit of the present principles. Moreover, the following characteristics relating to threat level are also illustrative and, thus, other characteristics can also be used in accordance with the teachings of the present principles, while maintaining the spirit of the present principles. 
     In an embodiment, the threat level can be implemented as a nonlinear function of the various threats versus the activities involved. 
     The threat level can be symmetrical or asymmetrical. As an example, the threat level can be kept at a higher level once a high level is achieved and can be ratcheted back slowly thereafter. 
     In an embodiment, the threat level can be tracked temporally across multiple sessions and periods of time. 
     A description will now be given regarding several aspects of the present principles, in accordance with an embodiment of the present principles. 
     In an embodiment, the user is separated from any direct interaction with data/transaction system. 
     In an embodiment, the connection between the user and a computer related device is made through one or more multi-node processing pathways made of multiple layers of VM machines. In an embodiment, the VM machines come into existence only when correctly summoned and may last for varying lengths of time. In an embodiment, the placement topology of the VM machines is highly variable. In an embodiment, the placement of the machines is always occulted from the user and external visibility. 
     In an embodiment, each node of a multi-node processing pathway has a section to receive direction from the user or preceding nodes, a firewall section, and a section to direct subsequent nodes or actions. 
     In an embodiment, all communications, at all stages, are encrypted with multiple types of encrypted keys and may be rotated during sessions and be different from node to node. 
     A description will now be given regarding why the system and method provided in accordance with the present principles is essentially impervious to attacks. 
     To successfully beat the system, an attacker must successfully predict/crack the following: Internet Protocol (IP) address and the time the node is active (noting that active nodes appear and disappear); the number of nodes in the topology (which include a beginning node, a variable number of middle nodes, and end node); the locations of nodes; the encrypted keys of the nodes; the sequence of actions; and the timing of nodes being created and destroyed in the processing quantum form. 
     Thus, the system described above enables services to be offered and procured anonymously through a distributed peer to peer registry and optional one- and two-way anonymizing proxies. In order to pay for such services privately (and/or anomalously), in one or more embodiments of the present invention the system advertises (presents) through the distributed registry metadata indicating a cost in cryptocurrency for the services. This cryptocurrency is negotiated through an automated, anonymous mechanism and changes hands automatically. 
     A cryptocurrency is defined as a medium of exchange using cryptography to secure the transactions and to control the creation of new units of cryptocurrency. That is, cryptocurrency is a cyber-currency in which a contract is made between parties to set the value of the cryptocurrency, to control the level of cryptocurrency in the system, and to store the cryptocurrency in electronic databases, thus leading to a peer-to-peer system of digital currency. Cryptocurrency has several advantages over conventional currencies. 
     First, cryptocurrency allows purchases to be made with a certain level of anonymity, thus allowing companies to purchase goods and/or services without alerting competitors of such purchases. 
     Second, cryptocurrency is accessible to anyone with access to the Internet (e.g., via a smart phone), thus providing banking services to persons in economically undeveloped areas. 
     As described below, services advertised through the distributed registry described above are tagged with an attribute indicating cost in cryptocurrency. 
     Units of cost may be, for example, portions of a unit of cryptocurrency for: a unit of computing work done; an amount of storage per unit of time: a specific Software as a Service (SaaS) or Platform as a Service (PaaS) service for a specific completed job or for a unit of time; and/or a one-time brokered transaction such as an anonymized procurement of service over the distributed cloud network. This anonymity allows a company to ensure that services procured and paid for are not publicly disclosed, thereby protecting trade secrets, corporate business strategies, etc. Of course, payment of such services continues to be ultimately disclosed as required by tax and business code regulations. But the services themselves that are procured can remain secret. 
     Atomicity: Services procured through the distributed may be atomic such that several microtransactions are linked and executed in “all or nothing” form. For example, the procuring end user may choose to procure an offered service through two layers of anonymizing proxies. That is, two anonymizing proxies advertise that they will anonymize a particular SaaS service transaction for 0.00001 of a cryptocurrency unit, and the advertising SaaS service offers its service for 0.010 cryptocurrency unit for a unit of work. The procuring end station may then specify that the three transactions are atomic, sending the transaction through the first proxy and then the second to the SaaS server, with all three transactions executing together. 
     Provably Unspendable Fees: Services may optionally advertise for a provably unspendable cryptocurrency fee. For example, if a service provider does not desire to profit from the service but wants a mechanism that will prevent denial of service through massive overuse, the provider may require that in order to procure the service, the procuring party must “sacrifice” a certain amount of cryptocurrency. 
     Contracts, including escrow, mediation, and deposit: A preferred embodiment of the present invention includes the Atomicity feature, and uses Distributed Cryptocurrency Contracts (e.g., cryptocurrency software script) to enable two- or multi-party transactions with minimal need for trust between parties. Additional features of cryptocurrency contracts and scripts can be used to enable deposits to be made beforehand for certain procured services, and for payment to be rendered with untrusted third parties—human or automated—acting as escrow agents and/or dispute mediators. 
     Cryptocurrency services: A distributed cloud network may optionally be used to provide cryptocurrency-specific services including currency exchange and transaction privacy and/or anonymization services. 
     Thus, with respect now to  FIG.  5   , steps performed by one or more processors and/or other hardware devices to receive payment for services provided by the distributed registry is presented. 
     After initiator block  501 , one or more processors display the plurality of services specified by the distributed registry (see above) to the user device, as described in block  503 . 
     As described in block  505 , the processor(s) then append metadata describing a current cryptocurrency cost of each of the plurality of services to said each of the plurality of services. That is, each service is described in a descriptor, and each descriptor has metadata describing a cryptocurrency cost of the service. 
     As described in block  507 , the processors(s) receive a request from the user device for a particular service from the plurality of services. 
     As described in block  509 , in response to receiving a request from the user device for a particular service from the plurality of services, the processor(s) charge the current cryptocurrency cost to a cryptocurrency account associated with the user device and providing the particular service to the user device. 
     The flow-chart ends at terminator block  511 . 
     Thus, the process depicted in  FIG.  5    allows a user to anonymously pay for services presented in the distributed registry described above. 
     In one or more embodiments, the present invention is implemented in a cloud environment. It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed. 
     Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models. 
     Characteristics are as follows: 
     On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service&#39;s provider. 
     Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs). 
     Resource pooling: the provider&#39;s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). 
     Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time. 
     Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service. 
     Service Models are as follows: 
     Software as a Service (SaaS): the capability provided to the consumer is to use the provider&#39;s applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings. 
     Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations. 
     Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls). 
     Deployment Models are as follows: 
     Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises. 
     Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises. 
     Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. 
     Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds). 
     A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes. 
     Referring now to  FIG.  6   , a schematic of an example of a cloud computing node is shown. Cloud computing node  10  is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, cloud computing node  10  is capable of being implemented and/or performing any of the functionality set forth hereinabove. 
     In cloud computing node  10  there is a computer system/server  12 , which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with computer system/server  12  include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, hand-held or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like. 
     Computer system/server  12  may be described in the general context of computer system-executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Computer system/server  12  may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices. 
     As shown in  FIG.  6   , computer system/server  12  in cloud computing node  10  is shown in the form of a general-purpose computing device. The components of computer system/server  12  may include, but are not limited to, one or more processors or processing units  16 , a system memory  28 , and a bus  18  that couples various system components including system memory  28  to processor  16 . 
     Bus  18  represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus. 
     Computer system/server  12  typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server  12 , and it includes both volatile and non-volatile media, removable and non-removable media. 
     System memory  28  can include computer system readable media in the form of volatile memory, such as random access memory (RAM)  30  and/or cache memory  32 . Computer system/server  12  may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system  34  can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus  18  by one or more data media interfaces. As will be further depicted and described below, memory  28  may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention. 
     Program/utility  40 , having a set (at least one) of program modules  42 , may be stored in memory  28  by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules  42  generally carry out the functions and/or methodologies of embodiments of the invention as described herein. 
     Computer system/server  12  may also communicate with one or more external devices  14  such as a keyboard, a pointing device, a display  24 , etc.; one or more devices that enable a user to interact with computer system/server  12 ; and/or any devices (e.g., network card, modem, etc.) that enable computer system/server  12  to communicate with one or more other computing devices. Such communication can occur via Input/output (I/O) interfaces  22 . Still yet, computer system/server  12  can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter  20 . As depicted, network adapter  20  communicates with the other components of computer system/server  12  via bus  18 . It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server  12 . Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc. 
     Referring now to  FIG.  7   , illustrative cloud computing environment  50  is depicted. As shown, cloud computing environment  50  comprises one or more cloud computing nodes  10  with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone  54 A, desktop computer  54 B, laptop computer  54 C, and/or automobile computer system  54 N may communicate. Nodes  10  may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment  50  to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices MA-N shown in  FIG.  7    are intended to be illustrative only and that computing nodes  10  and cloud computing environment  50  can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser). 
     Referring now to  FIG.  8   , a set of functional abstraction layers provided by cloud computing environment  50  ( FIG.  7   ) is shown. It should be understood in advance that the components, layers, and functions shown in  FIG.  8    are intended to be illustrative only and embodiments of the invention are not limited thereto. As depicted, the following layers and corresponding functions are provided: 
     Hardware and software layer  60  includes hardware and software components. Examples of hardware components include: mainframes  61 ; RISC (Reduced Instruction Set Computer) architecture based servers  62 ; servers  63 ; blade servers  64 ; storage devices  65 ; and networks and networking components  66 . In some embodiments, software components include network application server software  67  and database software  68 . 
     Virtualization layer  70  provides an abstraction layer from which the following examples of virtual entities may be provided: virtual servers  71 ; virtual storage  72 ; virtual networks  73 , including virtual private networks; virtual applications and operating systems  74 ; and virtual clients  75 . 
     In one example, management layer  80  may provide the functions described below. Resource provisioning  81  provides dynamic procurement of computing resources and other resources that are utilized to perform tasks within the cloud computing environment. Metering and Pricing  82  provide cost tracking as resources are utilized within the cloud computing environment, and billing or invoicing for consumption of these resources. In one example, these resources may comprise application software licenses. Security provides identity verification for cloud consumers and tasks, as well as protection for data and other resources. User portal  83  provides access to the cloud computing environment for consumers and system administrators. Service level management  84  provides cloud computing resource allocation and management such that required service levels are met. Service Level Agreement (SLA) planning and fulfillment  85  provide pre-arrangement for, and procurement of, cloud computing resources for which a future requirement is anticipated in accordance with an SLA. 
     Workloads layer  90  provides examples of functionality for which the cloud computing environment may be utilized. Examples of workloads and functions which may be provided from this layer include: mapping and navigation  91 ; software development and lifecycle management  92 ; virtual classroom education delivery  93 ; data analytics processing  94 ; transaction processing  95 ; and network security processing  96  (for providing security in a communication network between a user device and a computer related device and for receiving payment for services offered through a distributed registry associated with the communication network as described herein). 
     The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention. 
     The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire. 
     Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device. 
     Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user&#39;s computer, partly on the user&#39;s computer, as a stand-alone software package, partly on the user&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user&#39;s computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention. 
     Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions. 
     These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks. 
     The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks. 
     The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions. 
     Reference in the specification to “one embodiment” or “an embodiment” of the present principles, as well as other variations thereof, means that a particular feature, structure, characteristic, and so forth described in connection with the embodiment is included in at least one embodiment of the present principles. Thus, the appearances of the phrase “in one embodiment” or “in an embodiment”, as well any other variations, appearing in various places throughout the specification are not necessarily all referring to the same embodiment. 
     It is to be appreciated that the use of any of the following “/”, “and/or”, and “at least one of”, for example, in the cases of “A/B”, “A and/or B” and “at least one of A and B”, is intended to encompass the selection of the first listed option (A) only, or the selection of the second listed option (B) only, or the selection of both options (A and B). As a further example, in the cases of “A, B, and/or C” and “at least one of A, B, and C”, such phrasing is intended to encompass the selection of the first listed option (A) only, or the selection of the second listed option (B) only, or the selection of the third listed option (C) only, or the selection of the first and the second listed options (A and B) only, or the selection of the first and third listed options (A and C) only, or the selection of the second and third listed options (B and C) only, or the selection of all three options (A and B and C). This may be extended, as readily apparent by one of ordinary skill in this and related arts, for as many items listed. 
     Having described preferred embodiments of a system and method (which are intended to be illustrative and not limiting), it is noted that modifications and variations can be made by persons skilled in the art in light of the above teachings. It is therefore to be understood that changes may be made in the particular embodiments disclosed which are within the scope of the invention as outlined by the appended claims. Having thus described aspects of the invention, with the details and particularity required by the patent laws, what is claimed and desired protected by Letters Patent is set forth in the appended claims.
