  • Publication number: 20060053232
    Abstract: 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).
