A receiver includes: a broadcast reception unit configured to receive a broadcast signal; a keyword acquisition unit configured to acquire a search keyword based on metadata included in the broadcast signal; and a transmission unit configured to transmit the search keyword acquired by the keyword acquisition unit to a terminal device.

Terminal cooperation system, receiver, and receiving method

A receiving device includes: an output unit configured to output content broadcast from a transmitting device; an application execution unit configured to execute an application; a security policy acquiring unit configured to acquire security policy level data sent from the transmitting device with respect to the application, the security policy level data indicating a sorted level of the application; a policy level acquiring unit configured to acquire policy level data sent from the transmitting device with respect to currently broadcast content, the policy level data indicating a sorted level of the currently broadcast content; a determining unit configured to determine whether or not the application is an application to be controlled, based on the policy level data acquired by the policy level acquiring unit and the security policy data of the application acquired by the security policy acquiring unit; and an application control unit configured to instruct the application execution unit to control the application determined to be the application to be controlled.

Receiving device, transmitting device, broadcasting system, receiving method, and non-transitory computer-readable recording medium

For enabling single sign-on among applications, a linkage ID indicating connection between the authentication apparatusincluding the client function and the server apparatusis shared among a plurality of applications. For that, a SV information management unit Aa of the authentication apparatushaving the client function manages the linkage ID by storing it in a predetermined storing unit. An AP information management unit Ab manages and stores connection information between applications in a predetermined storing unit, wherein the connection information includes an application name corresponding to an application. Then, an AP decision unit determines whether an application name included in a received linkage ID request is registered in the AP information management unit Ab, obtains the linkage ID from the SV information management unit Aa when the application name is registered in the AP information management unit Ab, and returns the linkage ID to a source of the linkage ID request.

Authentication apparatus, authentication method, and authentication program implementing the method

An authentication system includes node devices, wherein a first node device transmits the authentication information thereof to a second node device, the second node device selects third node devices that are requested to verify the validity of the received authentication information, and transmits the authentication information to each of the selected third node devices, the third node device records verification information that is used to verify the validity of the authentication information of the first node device, verifies the validity of the authentication information on the basis of the authentication information and verification information, and transmits the result information to the second node device, and the second node device further derives weighted values indicating the reliability of the each verification of the third node devices and authenticates the first node device on the basis of the each result information and the each weighted value received from the third node devices.
