[Sequence from content upload to message reception]
Next, details of the functions of the management apparatus 1, the transmission side terminal 2, the reception side terminal 3, and the receiver 4 will be described using a sequence diagram.
First, the flow of processing until the receiving terminal 3 in the first embodiment receives a message will be described. FIG. 6 is a sequence diagram showing the flow of processing until the transmission side terminal 2 transmits a message to the reception side terminal 3.

  First, the content registration unit 251 of the transmission-side terminal 2 accepts content selection from the first user who uses the transmission-side terminal 2 (S10). When the content registration unit 251 accepts selection of content, the content registration unit 251 may accept content information, content creation date and time, text information for explaining the content, and the like. The content registration unit 251 associates the user ID of the first user, the selected content, and information related to the content, and transmits the associated information to the management apparatus 1.

When the storage control unit 121 of the management apparatus 1 receives the content from the transmission side terminal 2, the storage control unit 121 stores the content in the content storage unit 111 (S20).
Subsequently, the control information transmission unit 122 generates access control information for controlling access to the received content, and generates an access control URL as address information for access control including the access control information. (S30). Moreover, the control information transmission part 122 produces | generates content ID as content identification information. Then, the control information transmission unit 122 associates the access control information, the received user ID, the content ID, the content name, and the file name of the file indicating the content, and stores the content information in the content storage unit 111. Remember me. Note that the content information may include information related to the content received from the transmitting terminal 2.

  FIG. 7 is a diagram illustrating an example of content information stored in the content storage unit 111. As shown in FIG. 7, the content information includes a user ID, a content ID, a content name, a file name of a file indicating the content, and access control information. Here, the access control information includes character string information for uniquely specifying the content.

The control information transmitting unit 122 transmits the access control URL including the generated access control information to the transmitting terminal 2 corresponding to the content stored in S20.
Subsequently, when receiving the access control URL from the management device 1, the control information receiving unit 252 of the transmission-side terminal 2 receives from the first user the selection of the terminal corresponding to the user who wants to view the uploaded content. Here, the control information receiving unit 252 receives selection of the receiving terminal 3 used by the second user (S40).

Subsequently, the message transmission unit 253 generates a message including the received URL for access control, and transmits the message to the receiving terminal 3. Here, the message is, for example, an e-mail message, but is not limited thereto, and may be a message corresponding to a short message service or an instant messenger service such as LINE (registered trademark).
The message receiving unit 361 of the receiving terminal 3 receives a message including the access control URL from the transmitting terminal 2.

  In the above description, the transmission side terminal 2 transmits a message including the access control URL to the reception side terminal 3, but the present invention is not limited to this. For example, the management apparatus 1 may be provided with a message transmission function such as web mail, and may receive the address of the reception side terminal 3 and the message to be transmitted to the reception side terminal 3 from the transmission side terminal 2. Then, the control information transmitting unit 122 adds an access control URL to the received message, and transmits the message to the receiving terminal 3 based on the address of the receiving terminal 3 received from the transmitting terminal 2. May be.

[Sequence from message reception to content display]
Next, the flow of processing from when the receiving terminal 3 in the first embodiment receives a message until the receiver 4 displays content will be described. FIG. 8 is a sequence diagram showing a processing flow from when the receiving terminal 3 receives a message until the receiver 4 displays content.

  When the message receiving unit 361 of the receiving terminal 3 receives the message, the message receiving unit 361 displays the message on the display unit 31 and accepts selection of the access control URL included in the message from the second user via the input unit 32. .

  Here, the program corresponding to the message reception unit 361 and the program corresponding to the receiver ID acquisition unit 362 and the request unit 363 are different programs. Therefore, the access control URL includes a URL schema for executing an access control program corresponding to the receiver ID acquisition unit 362 and the request unit 363. The second user can appropriately start the access control program stored in the receiving terminal 3 by a simple operation of simply clicking or touching the URL.

  The message receiving unit 361 determines whether or not the access control URL has been selected (S110). If it is determined that the access control URL has been selected, the message receiving unit 361 receives the control unit 36 by executing the access control program. It functions as a machine ID acquisition unit 362 and a request unit 363. Thereby, receiver ID acquisition part 362 starts acquisition of receiver ID (S120).

  Subsequently, the receiver ID acquisition unit 362 receives a receiver ID acquisition operation and acquires the receiver ID from the receiver 4. For example, the receiver ID acquisition unit 362 displays a message such as “Please bring your terminal close to the receiver 4” on the display unit 31 and accepts the acquisition operation. When the second user brings the receiving terminal 3 close to the receiver 4, the receiver ID acquisition unit 362 is provided in the receiver 4 by short-range wireless communication via the short-range wireless communication unit 34. The receiver ID is acquired from the short-range wireless tag 43.

  Subsequently, the request unit 363 transmits the request information for requesting permission to access the content to the management apparatus 1 including the acquired receiver ID and the access control information included in the selected access control URL. .

  When receiving the request information from the receiving side terminal 3, the access control unit 123 of the management device 1 corresponds the receiver 4 corresponding to the receiver ID included in the request information to the access control information included in the request information. Then, an access control process for enabling access to the content stored in the content storage unit 111 is executed (S130).

  Specifically, in the access control process, in the access control process 123, the receiver 4 corresponding to the receiver ID included in the request information received from the receiving terminal 3 corresponds to the access control information included in the request information. Address information for accessing the content is generated. Then, the access control unit 123 associates the receiver ID, the content ID of the content, and the address information, and causes the address information storage unit 112 to store them as list information.

  FIG. 9 is a diagram illustrating an example of list information stored in the address information storage unit 112. As shown in FIG. 9, the list information includes a receiver ID, a content ID, and address information. The list information is referred to when the content providing unit 124 provides content to the receiver 4.

The access control unit 123 transmits response information to the receiving terminal 3 in response to the content being accessible to the receiver 4.
In response to receiving the response information, the request unit 363 of the receiving terminal 3 causes the display unit 31 to display information indicating that the receiver 4 can access the content. For example, when the request unit 363 of the receiving terminal 3 can communicate with another terminal associated with the receiver 4, the receiver 4 can access the content with respect to the other terminal. You may notify the information which shows that. By doing in this way, for example, the family of the 2nd user who lives in the 2nd user's house can grasp that the inspection of contents became possible.

  Subsequently, the content acquisition unit 451 of the receiver 4 determines whether or not a content acquisition operation has been received from the second user via the input unit 42 (S140). When the content acquisition unit 451 determines that a content acquisition operation has been received, the content acquisition unit 451 acquires from the management device 1 content that is accessible to its own receiver ID. Specifically, the content acquisition unit 451 acquires address information corresponding to its own receiver ID, and acquires content that is accessible to its own receiver ID based on the address information.

More specifically, when the content acquisition unit 451 determines that the content acquisition operation has been received, the content acquisition unit 451 transmits the receiver ID of the receiver 4 to the management device 1.
When receiving the receiver ID, the content providing unit 124 of the management device 1 acquires the content ID and address information associated with the receiver ID in the address information storage unit 112. Then, the content providing unit 124 specifies a content name associated with the content ID in the content storage unit 111. Then, the content providing unit 124 generates screen information in which the identified content name is associated with the acquired address information, and transmits the screen information to the receiver 4.

  The content acquisition unit 451 of the receiver 4 acquires the screen information and accepts selection of address information included in the screen information. When the address information is selected, the content acquisition unit 451 transmits the address information to the management apparatus 1.

When the content providing unit 124 of the management device 1 receives the address information from the receiver 4, the content providing unit 124 refers to the content storage unit 111 and the address information storage unit 112 and specifies the file name of the content associated with the address information. Then, the content providing unit 124 acquires the file with the file name and transmits it to the receiver 4.
The display control unit 452 of the receiver 4 displays content on the display unit 41 based on the received file (S150).

[Effect in the first embodiment]
As described above, in the access control system S according to the first embodiment, the message receiving unit 361 of the receiving terminal 3 receives a message including access control information for controlling access to content, and receives a receiver ID. The acquisition unit 362 acquires the receiver ID from the receiver 4, and the request unit 363 includes request information that includes the acquired receiver ID and the selected access control information and requests permission to access the content. It transmits to the management apparatus 1. Then, the content acquisition unit 451 of the receiver 4 acquires from the management device 1 the content that is accessible to its own receiver ID.

  By doing in this way, the access control system S can display content limited to the receiver 4 corresponding to the receiver ID acquired by the receiving terminal 3. Therefore, the first user of the transmitting side terminal 2 transmits the message including the access control information corresponding to the content only to the receiving side terminal 3 of the second user who is a family etc. The content can be viewed only by the receiver 4 that performs the operation. Even when the first user erroneously transmits a message to a third party, the content can be viewed only at the receiver used by the third party. Therefore, the access control system S can minimize content leakage.

  Further, in the access control system S, the second user uploads the first user by a simple operation of selecting the access control URL included in the message received from the first user and reading the receiver ID from the receiver 4. You can browse the content you have done. For this reason, even a user such as an elderly person who is not familiar with wireless communication means such as Bluetooth and Wi-Fi, which are complicated to set up, can view the content.

  Further, the receiver ID acquisition unit 362 of the receiving terminal 3 acquires the receiver ID stored in the short-range wireless tag by short-range wireless communication. By doing in this way, when the receiving terminal 3 acquires the receiver ID, the second user does not need to manually input the receiver ID. It is possible to prevent the content from being viewed.

  In the access control system S, the receiver terminal 3 acquires the receiver ID of the receiver 4 from the short-range wireless tag 43 and transmits request information including the receiver ID to the management apparatus 1, thereby receiving the receiver. 4, the content can be browsed. As a result, even if only communication from the receiver 4 to the receiving terminal 3 can be performed, the content can be browsed in the receiver 4. In addition, since the short-range wireless tag is inexpensive among short-range wireless communication devices, the provider of the receiver 4 suppresses the manufacturing cost of the receiver 4 corresponding to the short-range wireless communication at a low price, and allows the user to receive the receiver. 4 can be provided at low cost.

  The storage control unit 121 of the management device 1 stores the content received from the transmission-side terminal 2 as it is, but is not limited thereto. For example, the storage control unit 121 may store a plurality of the same content with different qualities. Then, the content acquisition unit 451 of the receiver 4 may transmit the receiver ID to the management apparatus 1 and may transmit model information indicating the model of the receiver 4. Then, the content providing unit 124 of the management device 1 may select content of optimum quality based on the model information and transmit content corresponding to the quality to the receiver 4.

  Moreover, although the receiving side terminal 3 acquired receiver ID of the receiver 4 from the near field wireless tag 43, it is not restricted to this. For example, when the receiving side terminal 3 and the receiver 4 are communicably connected via a network such as a LAN, the receiving side terminal 3 is connected to the UPnP (Universal Plug and Play) or the like via the network. You may acquire receiver ID from the receiver 4 with a protocol. Further, the receiver terminal 3 receives the receiver ID of the receiver 4 associated with the receiver terminal 3 in a remote viewing service in which the content stored in the receiver 4 can be viewed on the receiver terminal 3. May be obtained from a system that provides a remote viewing service.

  Further, the receiving side terminal 3 may include all the means for obtaining the receiver ID described above. In this case, the receiving side terminal 3 first tries to acquire the receiver ID from the system that provides the remote viewing service, and also tries to acquire the receiver ID using a protocol such as UPnP. Then, if the receiving side terminal 3 fails to acquire the receiver ID, the receiving side terminal 3 displays a message such as “Please bring your terminal close to the receiver 4” on the display unit 31, and the receiver ID An acquisition operation may be accepted.
