    摘要: A digital content distribution system (1) is composed of a right management server (100) and a user terminal (110) which are connected via a transmission line (120). The right management server (100) is made up of: a license data generating unit (304) which issues license data (usage right information) (1700) indicating a usage rule of content that is a digital copyrighted work to the user terminal (110); and an access condition setting unit (305) which notifies the user terminal (110) of update information (access condition) regarding necessity of updating the license data (1700) issued to the user terminal (110). The user terminal (110) is made up of: a content DB (701) which stores content; a license data DB (702) which stores the license data (1700) issued by the license data generating unit (304); a content reproducing unit (710) which uses the content stored in the content DB (701) in accordance with the usage rule indicated by the license data (1700) stored in the license data DB (702); and a license data upgrading unit (706) which requests the right management server (100) to update the license data (1700) stored in the license data DB (702) in accordance with the access condition notified by the access condition setting unit (305).

    摘要: A user terminal (110) having a license purchase unit (603) obtaining a license (500) indicating a content usable time (502) of a content data (200) composed of a plurality of elements (203), each of which can be replayed individually. The user terminal (110) also having an availability judgment unit (604) judging whether or not encrypted elements (203) included in the content data (200) are available, based on the content usable time (502) indicated in the obtained license (500), and having a replay/display unit (607) replaying the encrypted elements judged as available. In addition, the user terminal (110) having a use status management unit (608) specifying license-consuming elements, each of which consumes an authorized amount of replay under right, out of the elements that are being replayed, and measuring a content used time (504) consumed by replaying the specified license-consuming elements.

    摘要: The transmission format A license conversion unit (430) of the terminal device (120) converts the transmission format license (710), which is obtained from the license relay server (110), described in a transmission format into a processing format license (510) to be specified by the conversion format specification information (711) and detects modifications on the license whose format has already been converted by performing a signature verification on the after-conversion processing format license (510) using a processing format signature (712).

    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.
