    摘要： A group management server in a group information management system includes: a group member terminal list storage unit for storing a group member terminal list; and a secure communication unit for establishing a secure communication channel with a plurality of terminal apparatuses and communicating with each of the terminal apparatuses via the communication channel. Each terminal apparatus includes a tamper-resistant module. The tamper-resistant module includes: a group information storage unit for storing group information securely; a deletion unit for securely executing deletion, which is processing that affects the group member terminal list, of the group information stored in the group information storage unit; and a secure communication unit for establishing a secure communication channel with the secure communication unit and transmitting a complete deletion notification message via the communication channel.

    摘要： A management device of a license management system acquires a usage request of a content from an SD card or a printer via a relay device, analyzes the acquired usage request, acquires usage environment information of the SD card or the printer from the relay device, analyzes the acquired usage environment information, generates license information including a usage rule corresponding to the analysis results of the usage request and the usage environment information, generates instruction information indicating how to handle the license information in the relay device based on the analysis result of the usage environment information, embeds the generated instruction information in the license information, and sends the license information to the relay device. The relay device receives the license information in which the instruction information is embedded, and transfers the received license information to the SD card or the printer according to the instruction information which is embedded in the license information with performing certain processing or without performing any processing to the license information.

    摘要： A contents using device (or a terminal device) 300 is composed of: a license processing unit 305 which judges, on the basis of a usage rule of a license, whether or not the content is available; a content reproduction unit 304 which uses the content judged by the terminal device 300 to be available; a restriction unit (or a content reproduction unit 304) which restricts the license corresponding to the contents from being used by another source by reason that the license is currently in use, for a time period between a start and a normal end of the content usage by the content reproduction unit 304; an event detection unit 307 which detects a predetermined event that occurs between the start and the normal end of the content usage and that forcefully aborts the content usage; a restriction-relaxation necessity judgment unit (or a recovery/penalty judgment unit) 309 which judges whether or not the predetermined event is against an intention of a user; and a restriction relaxation unit (or a license recovery unit) 306 which relaxes the restriction on the content usage when the recovery/penalty judgment unit 309 judges that the predetermined event is against the intention of the user.

    摘要： When license information is transferred between a server machine and a client machine, an identifier which is unique to a series of communication sequences is provided. The identifier is sent when a communication is performed between the two machines, as well as when the license information is updated. Therefore, when a message for transferring the license information is received by the use of the same identifier, a response message is returned without updating the license information.
