Upon receiving the program list request from the service providing device 10, the AP 41 of the cloud 14 executes a series of processes (73).

Here, as shown in FIG. 4, the AP41 of the cloud 14 can obtain the public key for each user corresponding to the user ID of the smartphone 11 by referring to the authentication information table 40. Returning to FIG. 7, the AP41 generates a nonce (Nonce: number used once) in executing the authentication process of the user (smartphone 11) (73-1). The nonce (referred to as n) is a random value (random number), and is usually used only in one authentication process. Next, the AP 41 generates encrypted data (c) in which the STB-ID, the user ID, and the nonce (n) are encrypted with the public key acquired from the authentication information table 40 (73-2).

The AP41 of the cloud 14 transmits an authentication request including the STB-ID, the user ID and the encrypted data (c) to the AP22 of the service providing device 10 via the Internet 13 (73-2). When the AP 22 of the service providing device 10 receives the authentication request (including STB-ID, user ID, and c) from the cloud 14, it transmits the authentication request to the BT middleware 231 (74). The BT middleware 231 transmits the received authentication request (STB-ID, user ID, c) to the BT middleware 331 of the smartphone 11 by the BT wireless communication 17 (75).

When the BT middleware 331 of the smartphone 11 receives the authentication request from the service providing device 10, it executes a series of processes (76). Here, as shown in FIG. 3, the smartphone 11 can acquire the private key by referring to the key management table 31.

Returning to FIG. 7, the BT middleware 331 of the smartphone 11 decrypts the encrypted data (c) included in the authentication request with the private key acquired from the key management table 31 and outputs the decrypted data (d) ( 76-1). Next, the BT middleware 331 executes a calculation for calculating the hash value (h-1) of the decrypted data (d) (76-2). After such processing, the BT middleware 331 transmits an authentication processing request (including STB-ID, user ID, and h-1) to the BT middleware 231 of the service providing device 10 by the BT wireless communication 17 (76-). 3).

When the BT middleware 231 of the service providing device 10 receives the authentication processing request (including STB-ID, user ID, and h-1) from the smartphone 11, it transmits to the AP 22 (77). When the AP 22 of the service providing device 10 receives the authentication processing request, it transmits the authentication processing request to the AP 41 of the cloud 14 via the Internet 13 (78).

Upon receiving the authentication processing request (including STB-ID, user ID, and h-1) from the service providing device 10, the AP41 of the cloud 14 executes a series of processing (79). AP41 performs a calculation (79-1) to calculate a hash value (h-2) of data including STB-ID, user ID and nonce (n). AP41 determines that the authentication is successful if the hash value (h-1) included in the authentication processing request and the hash value (h-2) match (80), and determines that the authentication fails if they do not match. Judgment (81).

In the case of successful authentication, AP41 of the cloud 14 transmits an authentication completion notification (including STB-ID, user ID, and information indicating authentication success) to AP22 of the service providing device 10 via the Internet 13. (80-1). Further, the AP 41 transmits the program list response (including the STB-ID, the user ID, and the program list) to the AP 22 of the service providing device 10 (80-2).

Upon receiving the authentication completion notification from the cloud 14, the AP 22 of the service providing device 10 completes the authentication process of the smartphone 11 (80-3). Further, when the program list response is received from the cloud 14, a service process of presenting the program list to the user who watches the TV 12 at home is executed (80-4). Specifically, the AP 22 of the service providing device 10 controls the TV 12 to display the program list provided by the cloud 14.

In this way, the service providing device 10 can provide the program list via, for example, the TV 12 in response to the request from the authenticated smartphone 11 user in cooperation with the cloud 14. Here, since the cloud 14 can perform authentication processing for each user, it is possible to provide a program list corresponding to a request for each user.

On the other hand, in the case of authentication failure, the AP41 of the cloud 14 sends an authentication completion notification (including STB-ID, user ID, and information indicating the authentication failure) to the AP22 of the service providing device 10 via the Internet 13. Send (81-1). Further, the AP 41 transmits a program list response (including STB-ID, user ID, NG, and authentication required) to AP 22 of the service providing device 10 (81-2). That is, this program list response means that the requested program list cannot be provided and that the authentication process needs to be performed again.

Upon receiving the authentication completion notification from the cloud 14, the AP 22 of the service providing device 10 completes the authentication process of the smartphone 11 (81-3). Further, when the AP 22 receives the program list response from the cloud 14, the AP 22 transmits to the smartphone 11 that the authentication has failed by the BT wireless communication 17 (81-4). Therefore, the user is notified that the requested program list is not provided and that the authentication process needs to be performed again.

FIG. 8 is a sequence diagram for explaining the notification process of the smartphone 11. The smartphone 11 executes a background operation and executes a notification process for notifying that the smartphone 11 is located in the vicinity of the device (STB) 10 (S10, S11).

As shown in FIG. 8, the BT middleware 331 of the smartphone 11 executes an advertising process for discovering peripheral BT devices and making a communication connection (90). This advertising process is a process of notifying peripheral BT devices of information including transmission power and RSSI (Received Signal Strength Indicator), and is executed in the background operation by a plurality of smartphones (11-1 to 11-n). To. Here, the service providing device 10 has a timer 24 for executing the smartphone list notification timer process and the smartphone list update timer process, as will be described later. The timer 24 operates when the service providing device 10 is started.

When the BT middleware 231 of the service providing device 10 receives the advertising from the smartphone 11, it executes a series of processes (91). That is, the BT middleware 231 calculates the distance from the device (STB) 10 to the notified smartphone 11 (91-1). The BT middleware 231 determines from the calculated distance whether or not the smartphone 11 exists in the vicinity (predetermined range) around the device (STB) 10 (91-2).

Based on the determination result, the service providing device 10 records the smartphone 11 existing at a position near the periphery in the user position management table 21 (91-3). Here, as shown in FIG. 2, the user position management table 21 records the user ID of the smartphone 11 existing at a nearby position and the information of the last update date and time.

Returning to FIG. 8, the service providing device 10 executes a series of processes (92) by the smartphone list notification timer function of the timer 24. That is, the timer 24 executes a cycle timer operation for notifying at regular time intervals as a smartphone list notification timer process (92-1). When the BT middleware 231 receives the smartphone list notification at regular intervals (92-2), the BT middleware 231 generates a list of smartphones 11 (list of user IDs) existing in the vicinity of the device (STB) 10 to generate a service providing device. It is transmitted to AP22 of 10 (92-3).

Further, the service providing device 10 executes a series of processes (93) by the smartphone list update timer function of the timer 24. That is, the timer 24 executes a cycle timer operation for notifying at regular time intervals as a smartphone list update timer process (93-1). When the BT middleware 231 receives the smartphone list update notification at regular intervals (93-2), the BT middleware 231 checks the user position management table 21 (93-3). When the BT middleware 231 determines from the user position management table 21 that the last update date and time has elapsed from a predetermined time, the BT middleware 231 deletes the list of user IDs as past record information (93-4).

As described above, the service providing device 10 can periodically update the user position management table 21 and acquire the latest list of smartphones 11 (list of user IDs) existing in the vicinity of the periphery. As a result, the service providing device 10 presumes that each user of the smartphone 11 existing in the vicinity of the periphery is watching the TV 12, and transmits the list of each user to the AP 41 of the cloud 14 via the Internet 13. can. Therefore, since the cloud 14 can estimate the program of the TV 12 that each specified user is watching at regular time intervals, it is possible to collect information effective for the service provision process.

FIG. 9 is a sequence diagram for explaining an example of the second service providing process. The second service provision process is a service provision process executed by the service providing device 10 in cooperation with the cloud 14 when, for example, a user on the go accesses the cloud 14 (S9 in FIG. 5).

Here, as described above, the AP41 of the cloud 14 can acquire the public key for each user corresponding to the user ID of the smartphone 11 from the authentication information table 40. The AP 41 generates a nonce (n) in executing the authentication process of the user (smartphone 11) (102-1). Next, the AP 41 generates encrypted data (c) in which the STB-ID, the user ID, and the nonce (n) are encrypted with the public key acquired from the authentication information table 40 (102-2).

Further, the AP 41 of the cloud 14 transmits an authentication request including the STB-ID, the user ID and the encrypted data (c) to the smartphone 11 via the Internet 13. When the BT middleware 331 of the smartphone 11 receives an authentication request (including STB-ID, user ID, and c) from the cloud 14 (103), it executes a series of processes (104).

That is, the BT middleware 331 of the smartphone 11 decrypts the encrypted data (c) included in the authentication request with the private key acquired from the key management table 31 and outputs the decrypted data (d) (104-1). .. Next, the BT middleware 331 executes a calculation for calculating the hash value (h-1) of the decrypted data (d) (104-2). After such processing, the BT middleware 331 transmits an authentication processing request (including STB-ID, user ID, and h-1) to AP41 of the cloud 14 via the Internet 13.

When the AP41 of the cloud 14 receives the authentication processing request (including STB-ID, user ID, and h-1) from the smartphone 11 (105), it executes a series of processing (105). That is, AP41 executes a calculation to calculate a hash value (h-2) of data including STB-ID, user ID and nonce (n) (105-1). The AP41 determines that the authentication is successful if the hash value (h-1) included in the authentication processing request and the hash value (h-2) match (106), and determines that the authentication fails if they do not match. Judgment (107).

In the case of successful authentication, AP41 of the cloud 14 transmits an authentication completion notification (including STB-ID, user ID, and information indicating authentication success) to the smartphone 11 via the Internet 13 (106-1). .. As a result, the BT middleware 331 of the smartphone 11 receives the authentication completion notification (106-2).

Further, the AP 41 transmits a program recording request (including STB-ID, a user ID, and information indicating successful authentication) to the AP 22 of the service providing device 10 via the Internet 13 (106-3). The AP 22 of the service providing device 10 controls the recorder of the TV 12 to execute the program recording process of recording the program content in response to the program recording request (106-4). After executing the program recording process, the AP 22 transmits a program recording response (including STB-ID, a user ID, and information indicating the result of the program recording) to the AP 41 of the cloud 14 via the Internet 13 (106-5). ).

When the AP 41 of the cloud 14 receives the program recording response from the AP 22 of the service providing device 10 (106-6), the AP 41 transmits the program recording response to the smartphone 11 via the Internet 13 (106-7). When the BT middleware 331 of the smartphone 11 receives the program recording response (106-8), it transmits it to the AP32 of the smartphone 11. Upon receiving the program recording response (106-9), the AP32 of the smartphone 11 executes a process of notifying the user of, for example, the completion or failure of the program recording, depending on the result of the program recording.
