摘要： When a secure counter malfunction detection unit 212 deters a malfunction in a secure counter 211, a content playability judgment unit 206 performs a content playability judgment based on information managed by a malfunctioning-state playback processing management unit 214. The malfunctioning-state playback processing management unit 214 stores a malfunctioning-state playback condition composed of information such as a playback count and a playback time. The content playability judgment unit 206 judges that content is playable when the malfunctioning-state playback condition is met, and a content playback unit 210 splays the content.

摘要： A content usage management system includes a terminal device using content as digital production and a server device managing usage of the content on the terminal device. The server device includes a license information memory unit that memorizes license information indicating a usage rule of the content based on a user of the terminal device, and a license ticket issuance unit that generates a license ticket as right information indicating a part or all of a usage rule on the license information corresponding to the user based on a request from the user. The terminal device includes a requesting unit that requests usage of the content to the server device according to the user's designation, a receiving unit that receives the license ticket sent from the server device, and a content usage control unit that controls usage of the content according to the usage rule indicated on the received license ticket. The requesting unit makes a request by sending expected information indicating content to be requested and a usage volume of the content, and the license ticket issuance unit generates a license ticket according to the expected information sent from the requesting unit and sends the license ticket to the terminal device.

摘要： In a right management server (100), a license data generation/updating unit (307) generates license data (900) including a use condition (503) for permitting a user to use a content based on a content use right (500) owned by the user. A subset use condition setting unit (308) sets a subset use condition (901) for temporarily invalidating the license data (900) in the license data (900). A communication unit (311) transmits the license data (900) in which the subset use condition (901) is set to the user terminal (110), and receives the license data (900) returned from the user terminal (110). Upon receipt of the invalidated license data (900), the license data generation/updating unit (307) cancels the invalidation of the license data (900) by updating the subset use condition (901).
