    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).

    摘要: The content distribution system according to the present invention is comprised of: a server device and a terminal device, the server device providing the terminal device with a license for using a content based on transaction processes, each including receiving of a request message, sending of a response message, and receiving of a commit message for finalizing completion of a transaction, and the terminal device controlling use of the content based on the license obtained from the server device, wherein the terminal device includes: a holding unit that holds a 1-bit transaction identification flag indicating whether a current transaction process is in progress or completed; and a sending unit that sends the transaction identification bit instead of an omitted commit message when sending a second or later request message, without sending a commit message in each transaction process except for a last transaction process in successive transaction processes, and the server device includes: a receiving unit that receives the transaction identification flag that is sent together with the second or later request message in the successive transaction processes; and a judgment unit that judges whether or not completion of one transaction should be finalized based on the received transaction identification flag.

    摘要: A method for judging use permission of information on one or more terminal apparatuses which uses content provided by a content provider and metadata provided by a metadata provider and supplementing the content, the method comprising: metadata use permission judgment judging use permission of the metadata based on usage control information regarding use control of the metadata; and using the metadata in the case where in said metadata use permission judgment, the use of the metadata is permitted. Specifically, the usage control information includes the first signer identification information which identifies the range of the provider of the metadata that can be used. The metadata includes a signature of the metadata provider identified in the first signer identification information, and the second signer identification information identifying the signer of the signature. And, said metadata use permission judgment judges the metadata use permission based on the metadata provider identified in said first signer identification information, said second signer identification information, and signature verification.

    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.
