Title: Content access based on location token

Description:
BACKGROUND 
     The present disclosure relates to the presentation of content to a user, more specifically to providing region restricted content to a user when they are located outside of the region. 
     People often travel to different locations around the world, and due to region restrictions imposed on content are not able to access content that they would normally access at home. The individual may have no desire to access content that originates where they have traveled to. This can include reasons such as language barriers, a general desire to remain connected to their home, etc. Many people attempt to bypass the region restrictions on the content by connecting through a virtual private network that fakes their current location to make it seem as though they are connecting from their home location. 
     SUMMARY 
     Embodiments of the present disclosure are directed to a system for providing content to a user outside of a home region. The system includes a portable device displays content to a user through a network connection. A home content provider provides content to the portable device from the home region. At least a portion of the content provided by the home content provider is region restricted content. A location verifier determines that the portable device and the user are both physically located within the home region. The location verifier issues to the user a location token when the user and the portable device are in the home region. The user then travels outside of their home region and attempts to access the region restricted content. A token verifier verifies the location token when the user requests the region restricted content outside of the home region. The token verifier further instructs the home content provider to provide region restricted content to the user when the user has the location token. 
     Embodiments of the present disclosure are directed to a computer implemented process for providing content to a user outside of a home region. A request is received to register with a content provider for a location token. The content provider provides region restricted content in an electronic format to the user. The process determines that the location token can be issued to the user based on a physical location of the user. A location token is issued to the user when the user is physically in the home region. The process receives an attempt to access region restricted content by the user from a location outside the home region. The process further receives the location token from a portable device associated with the user. The location token is then validated. If the location token is valid the region restricted content is provided to the user. If the location token is not valid access to the region restricted content is denied. The above summary is not intended to describe each illustrated embodiment or every implementation of the present disclosure.

     DETAILED DESCRIPTION 
     Aspects of the present disclosure relates to the presentation of content to a user, more specifically to providing region restricted content to a user when they are located outside of the region. While the present disclosure is not necessarily limited to such applications, various aspects of the disclosure may be appreciated through a discussion of various examples using this context. 
     Audio, visual, and print content that is provided to individuals is often time restricted to a particular region. Content providers are often limited in where, when, and how they can provide content to users. For example, in the United States, there are many television stations that provide content provided by a particular network. The network restricts each station to a particular region, and may limit the ability of one station providing content in an area that is covered by another station. For example, the NBC affiliate in Minneapolis, Minn. may not be allowed to provide their content to a consumer who is covered by the NBC affiliate located in Rochester, Minn. However, there are instances where the coverage of the two stations overlap. In some instances the Rochester NBC affiliate may request that other content providers, such as a cable company, block the Minneapolis NBC affiliate&#39;s content to protect an advertising stream or when they are showing competing content. In some instances the blocking would affect a consumer who is an area where the two stations overlap in their regional coverage. If the two networks are showing different content, such as two different sporting events, the consumer may not be able to watch content that they would otherwise be allowed to watch, but for the blocking. 
     Further, people often travel to locations around the world, and due to region restrictions are not able to access content that they would normally access at home. The individual may have no desire to access content that originates where they have traveled to. This can include reasons such as language barriers, a general desire to remain connected to their home, etc. For example, a person from the United Kingdom who is traveling to the United States is unable to access content provided by the BBC while they are in the United States. However, the individual may desire to keep up with the current status of Brexit or other local event in the United Kingdom, while traveling in the United States, but the content such as live news from the BBC in the United Kingdom is not available in the United States due to region restrictions. Further, as Brexit is not a popular news item in the United States, the individual would not be able to get this information easily from sources located in the United States. 
       FIG. 1  is a block diagram of a system  100  for providing access to content at a remote location  112  that would not normally be accessible at that location. System  100  includes home region  110  and a remote location  112 . System  100  includes a home content provider  120 , a location verifier  130 , a token verifier  140 , a portable device  150 , and a network  160 . 
     Home region  110  is a region where a user of the portable device  150  normally receives content. For example, the home region  110  can be North America, the United States, Canada, and/or a more specific location such as a town or state/province. The home location has content that is provided to the user that is restricted to that region, and not available to users who are located outside of the home location. The remote location  112  is any other region of the world that is not the home location. 
     The home content provider  120  is a provider of content to the user. The content can be video, audio, print, or any other digital content that can be provided to the user for consumption on the portable device  150 . For example, the home content provider  120  can be a newspaper, a television station, a television network, a cable or satellite provider, a streaming service, such as Netflix, Amazon, Disney+, AppleTV, Hulu, Pandora, Spotify, etc. The content provider  120  has content that includes region restricted content. Content may be restricted for a variety of reasons. For example, the owner of the content being provided by the home content provider  120  may impose distribution limitations on the content that prevents the home content provider  120  from providing the content outside the home region  110 . The content provider  120  may have agreements with different content provider  120   s  that give the rights to a particular content to one content provider  120  in one region and another content provider  120  in another region. In some instances, the content provided by the content provider  120  can be restricted by a government or other authority from being provided within the region controlled by that authority. For example, a government may find that a particular piece of content is offensive or subversive to their community, and therefore, do not want its subjects to have access to that content. However, it may be permitted in that region for “non-residents” or visitors to view that particular content. In these instances, the content provider  120  may not be able to differentiate persons who are allowed to have the content in that area and those that are not, and as a result may choose to block delivery of that content to any user located in that particular region. Until such time as the content provider  120  receives a confirmation that the user has a valid location token, the content provider  120  will not provide region restricted content outside of the home region  110 . 
     Location verifier  130  is a component of the system  100  that verifies that user is in a particular location. The location verifier  130  can be part of a system within the content provider  120 , or the location verifier  130  can be a separate service that is provided to the user. The user interacts with the location verifier  130  to request the issuance of a location token  135  that will permit the user to view region restricted content outside of the home region  110 . The interaction with the location verifier  130  can be done through a user interface that is provided to the user either by the location verifier  130  or the content provider  120 . For example, the content provider  120  can through, for example, an account management portal, allow the user to request a location token. The user can simply check a box indicating that they desire a location token. 
     The location verifier  130  determines where the user is located, and uses this information to determine if and when to issue to the user a location token. The location verifier  130  obtains information from the user&#39;s portable device  150 , as well as, the network connection that the user is using to access the location verifier  130 . This information can include, for example, a MAC address for the portable device  150 , an account number associated with the content provider  120 , passwords, date, IP address, etc. Based on the information received from the user&#39;s portable device  150 , the location verifier  130  determines whether or not to issue to the user a location token. The location verifier  130  verifies that the user is located in a particular region. In some embodiments the location is verified using the IP address that the portable device  150  is connecting with the location verifier  130 . In some embodiments, the location verifier  130  will not verify a connection that is secured through a VPN, or similar connections where the user can “fake” their location so as to appear as though they are located somewhere they are not. In some embodiments, the location verifier  130  can use a two-factor authentication to ensure the user is located where they claim to be. For example, the operator of the location verifier  130  can send a letter containing an authorization code to the user to a physical address associated with the user. The user would then enter this code back to the verifier to confirm that they received it. In some embodiments, the location verifier  130  can access a GPS receiver on the portable device  150 , and use the GPS information to verify the location of the user within the correct region. 
     The location token  135  is a token that is provided to the user to allow the user to access the region restricted content at the remote location  112 . The token  135  can, in some embodiments, be tied to a specific user device. In this instance, the characteristics of the user device are associated with the token  135  and can be used in the validation process of the token. In some embodiments, the token  135  can be portable between user devices, or associated with multiple user devices. In some embodiments, the token  135  can allow access to all of the region restricted content. However, in other embodiments, only a subset of region restricted content can be unlocked by the token. The token  135  can be provided to the user as an electronic download that the user would download to the particular portable device  150  that they wish to receive the content. In some embodiments, the token  135  or the code to unlock the token  135  can be mailed to the physical address of the user. In this way the location verifier  130  can enact a second layer of security in ensuring that the token  135  is provided to a user in the correct region. In some embodiments, the token  135  is configured to expire. The token  135  can expire after a predetermined period of time, such as after a week, after 30 days, or any other period of time. In some embodiments, the token  135  can expire after a predetermined number of accesses of region restricted content. For example, the token  135  can expire after the user access  10  region restricted pieces of content. Once the token  135  has expired, the user cannot access the region restricted content outside of the region until they renew the token. The token  135  can only be renewed by returning back to the home region  110 , and revalidating the token  135  by reperforming the process that was used to generate the token  135  in the first instance. 
     The token verifier  140  is a component of the system  100  that verifies that a presented token  135  is valid. The token verifier  140  receives a copy of the token  135  when the user attempts to access content from the content provider  120  that is not available in the remote location  112 . The token verifier  140  verifies that the presented token  135  is valid by comparing information associated with the token  135  with information obtained during the issuance of the token. This information can be stored in a database associated with the location verifier  130 , or can be extracted from the token  135  itself. If the token  135  is identified as valid the token verifier  140  communicates with the content provider  120  that the user has been validated and therefore, the content provider  120  is then able to provide the region restricted content to the user and their portable device  150 . If the token  135  is not validated or is determined to be expired, the user will not be able to access the region restricted content. 
     The portable device  150  is a device that the user receives content through. The portable device  150  is, as the name implies, portable in that the user can and usually does take the device to different locations. The portable device  150  can be a mobile phone, a laptop computer, a tablet, or any other portable electronic device that can provide content to the user. The portable device  150  has one or more applications that allow the user to access content from the content provider  120 . These applications can include apps that are specific to the content provider  120 , or can be generic applications, such as a web browser that allows the user to connect with the content provider  120 . The portable device  150  also includes one or more ways to connect to a network. These connections can include one or more of cellular connections, Wi-Fi connections, Bluetooth connections, wired network connections, wireless network connections, etc. The network is a computer infrastructure that allows the portable device  150  to connect and communicate with at least the content provider  120 . 
       FIG. 2  is a flow chart of a process for providing location restricted content to a user who is outside the restricted area for the content, according to illustrative embodiments. The user begins the process by registering or signing up with at least one content provider  120  that provides region restricted content. This is illustrated at step  210 . As discussed above, region restricted content is content that a content provider  120  cannot provide outside of a designated region. This may be for licensing or other reasons. During the registration process the user can request to view the region restricted content at a location outside of the region where the content is restricted to. In some embodiments the user can make a request for access to content in a specific region. For example, the user can request to view content restricted to the United States in Europe. In another example, the user can request to view content from the United Kingdom in the United States. In some embodiments, the user can request access to region restricted content without restriction to what region they wish to view the content in. 
     Once the user has requested access to the region restricted content the content provider  120  then needs to verify that the user is allowed to request access to the region restricted content. This is illustrated at step  220 . The content provider  120  can compare the user&#39;s provided credentials to an account associated with the user. If the user has an account, the content provider  120  then can determine that they are permitted to access the restricted content. The content provider  120  can determine for example, if the user has paid for access to the content, has a valid subscription to the content, or is otherwise entitled to access the content. Conversely if the user does not have an account or is not entitled to the restricted content the content provider  120  will deny the request. 
     Once the content provider  120  has determined that the user is entitled to access the content provider  120  then proceeds to determine if a location token  135  can be issued to the user. This is illustrated at step  230 . The content provider  120  accesses a location verifier  130  to determine where the user is physically located. As discussed above the location verifier  130  can be part of the content provider  120  or can be a separate service that is provided to the content provider  120 . The location verifier  130  determines the physical location of the user at the time of the request. In some embodiments, the location provider obtains information from the user&#39;s portable device  150 , as well as, the network connection that the user is using to access the location verifier  130 . This information can include, for example, a MAC address for the portable device  150 , an account number associated with the content provider  120 , passwords, date, IP address, etc. In some embodiments, the location verifier  130  will not verify a connection that is secured through a VPN, or similar connections. In some embodiments, the location verifier  130  can require that the user connects to the verifier using a piece of equipment provided by the content provider  120 , such as a specific router. In some embodiments, a two-factor authentication can be used to confirm the location of the user in the correct region. For example, a letter containing an authorization code can be sent to the user to their registered physical address. In some embodiments, the location verifier  130  can access a GPS receiver on the portable device  150 , and use the GPS information to verify the location of the user within the correct region during the request. 
     If the user is determined to be in their home location, then a location token  135  is issued to the user. This is illustrated at step  240 . The token  135  can be provided to the user as an electronic download that the user would download to the particular portable device  150  that they wish to receive the content. In some embodiments, the token  135  or the code to unlock the token  135  can be mailed to the physical address of the user. In this way a second layer of security is provided in ensuring that the token  135  is provided to a user in the correct region. 
     Once the user has been granted the location token, the user will have to leave their home region  110  and travel to a different region. This is illustrated at step  250 . The user then attempts to connect to the content provider  120  through a network connection in the remote location  112 . This is illustrated at step  260 . As the user is now in a region where the region restricted content is not available when the user attempts to access the content provider  120 , the content provider  120  can initially inform the user that the content is not available in their current region. The content provider  120  can provide this message to the user on the screen of their mobile device. This can be provided as a pop-up window that indicates that the content is not available, on a portion of the screen where the content would normally be provided, or any other way of notifying the user that the content is not available. 
     In response to receiving the notice that the content is not available in current region, the user submits to the content provider  120  the location token. This is illustrated at step  270 . The user can manually submit the location token  135  to the content provider  120  through a portal that is provided by the content provider  120 . In some embodiments the content provider  120  can provide a notification to the user, that the restricted content can be viewed by submitting the token. In this instance the user then submits the token  135  in response to the prompt. In some embodiments, the notification can be combined with the notification that the content is not available. In this instance the user also submits the token  135  in response to the prompt. In some embodiments, the content provider  120  can probe the portable device  150  to obtain the token. In some embodiments, the token  135  is provided to the content provider  120  before the user attempts to access the restricted content. In this instance, the content provider  120  does not provide any notification to the user that the content is restricted, nor does the content provider  120  request the token. 
     Once the content provider  120  receives the token  135  from the user, the token  135  is validated. This is illustrated at step  280 . The content provider  120  provides the received token  135  to the token verifier  140  in order to validate the token. The token verifier  140  verifies that the presented token  135  is valid by comparing information associated with the token  135  with information obtained during the issuance of the token. This information can be stored in a database associated with the location verifier  130 , or can be extracted from the token  135  itself. In some embodiments the token verifier  140  also checks that the particular token  135  has not expired or timed out. If the information matches the token verifier  140  determines that the presented token  135  is valid. If the information does not match or the token  135  is expired, the token verifier  140  determines that the token  135  is now invalid. In some embodiments, the validation process can include two-factor authentication. In this approach, once the token  135  is determined to be valid, a second contact is made with the user. This second contact can contain a code that the user will need to enter to receive the content. This “code” can be sent to the user device, or can be sent to a second device associated with the user. Once the user enters in the correct code, the validation process is completed. 
     If the token  135  was successfully validated, the user is then provided the content from the content provider  120  in the remote location  112 . This is illustrated at step  290 . If the token  135  was not validated, or the content cannot for whatever reason be provided at that region, the content provider  120  provides a message indicating that the content cannot be viewed. This is illustrated at step  295 . In some embodiments, the message can inform the user of the reason as to why the token  135  was determined to be invalid. For example, the token  135  may have expired, and the user would be informed that their token  135  has expired and that they will need to revalidate the token  135  in their home region  110 . 
     Referring now to  FIG. 3 , shown is a high-level block diagram of an example computer system  301  that may be used in implementing one or more of the methods, tools, and modules, and any related functions, described herein (e.g., using one or more processor circuits or computer processors of the computer), in accordance with embodiments of the present disclosure. In some embodiments, the major components of the computer system  301  may comprise one or more CPUs  302 , a memory subsystem  304 , a terminal interface  312 , a storage interface  316 , an I/O (Input/Output) device interface  314 , and a network interface  318 , all of which may be communicatively coupled, directly or indirectly, for inter-component communication via a memory bus  303 , an I/O bus  308 , and an I/O bus interface unit  310 . 
     The computer system  301  may contain one or more general-purpose programmable central processing units (CPUs)  302 A,  302 B,  302 C, and  302 D, herein generically referred to as the CPU  302 . In some embodiments, the computer system  301  may contain multiple processors typical of a relatively large system; however, in other embodiments the computer system  301  may alternatively be a single CPU system. Each CPU  302  may execute instructions stored in the memory subsystem  304  and may include one or more levels of on-board cache. 
     System memory  304  may include computer system readable media in the form of volatile memory, such as random access memory (RAM)  322  or cache memory  324 . Computer system  301  may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system  326  can be provided for reading from and writing to a non-removable, non-volatile magnetic media, such as 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”), or an optical disk drive for reading from or writing to a removable, non-volatile optical disc such as a CD-ROM, DVD-ROM or other optical media can be provided. In addition, memory  304  can include flash memory, e.g., a flash memory stick drive or a flash drive. Memory devices can be connected to memory bus  303  by one or more data media interfaces. The memory  304  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 various embodiments. 
     Although the memory bus  303  is shown in  FIG. 3  as a single bus structure providing a direct communication path among the CPUs  302 , the memory subsystem  304 , and the I/O bus interface  310 , the memory bus  303  may, in some embodiments, include multiple different buses or communication paths, which may be arranged in any of various forms, such as point-to-point links in hierarchical, star or web configurations, multiple hierarchical buses, parallel and redundant paths, or any other appropriate type of configuration. Furthermore, while the I/O bus interface  310  and the I/O bus  308  are shown as single respective units, the computer system  301  may, in some embodiments, contain multiple I/O bus interface units  310 , multiple I/O buses  308 , or both. Further, while multiple I/O interface units are shown, which separate the I/O bus  308  from various communications paths running to the various I/O devices, in other embodiments some or all of the I/O devices may be connected directly to one or more system I/O buses. 
     In some embodiments, the computer system  301  may be a multi-user mainframe computer system, a single-user system, or a server computer or similar device that has little or no direct user interface, but receives requests from other computer systems (clients). Further, in some embodiments, the computer system  301  may be implemented as a desktop computer, portable computer, laptop or notebook computer, tablet computer, pocket computer, telephone, smart phone, network switches or routers, or any other appropriate type of electronic device. 
     It is noted that  FIG. 3  is intended to depict the representative major components of an exemplary computer system  301 . In some embodiments, however, individual components may have greater or lesser complexity than as represented in  FIG. 3 , components other than or in addition to those shown in  FIG. 3  may be present, and the number, type, and configuration of such components may vary. 
     One or more programs/utilities  328 , each having at least one set of program modules  330  may be stored in memory  304 . The programs/utilities  328  may include a hypervisor (also referred to as a virtual machine monitor), one or more operating systems, one or more application programs, other program modules, and program data. Each of the operating systems, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Programs  328  and/or program modules  330  generally perform the functions or methodologies of various embodiments. 
     It is to be understood 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 that includes a network of interconnected nodes. 
     The system  100  may be employed in a cloud computing environment.  FIG. 4  is a diagrammatic representation of an illustrative cloud computing environment  450  according to one embodiment. As shown, cloud computing environment  450  comprises one or more cloud computing nodes  454  with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone  454 A, desktop computer  454 B, laptop computer  454 C, and/or automobile computer system  454 N may communicate. Nodes  454  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  450  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  454 A-N shown in  FIG. 4  are intended to be illustrative only and that computing nodes  454  and cloud computing environment  450  may communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).
