    摘要： The present invention provides a rights management terminal that can securely send and receive usage information while preventing spoofing and protecting user's privacy. The rights management terminal manages a copyright of a content using a license that includes a usage rule of the content, and includes: a first public key certificate management unit which manages, as a set, a first public key certificate that includes identification information for uniquely identifying at least one of the rights management terminal and a user using the terminal, and a first private key paired with a first public key included in the first public key certificate; a second public key certificate management unit which manages, as a set, a second public key certificate that does not include the identification information, and a second private key paired with a second public key included in the second public key certificate; a selection processing unit that selects, as a set, one of the following: the first public key certificate and the first private key; and the second public key certificate and the second private key; and an authentication processing unit that executes authentication for communicating with a server apparatus, using the public key and the private key that are selected as a set by the selection processing unit.

    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 broadcast station that is a transmission device assigns an ID and a license transformation period to a license to be generated, and transmits to a terminal apparatus 102, in order to provide a digital right management system which can provide a protection for the rights of a provider while preventing an unauthorized obtainment of a license to be transmitted through a digital broadcast. The terminal apparatus 102 records a license import log including the license ID and license transformation period assigned to the license. Further, the terminal apparatus 102 controls a license obtainment in the case where the same license has been obtained by the time of obtaining the license. Furthermore, the license received by the terminal apparatus 102 is kept at least until the license transformation period expires.

    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： The present invention provides a content reproduction terminal which can be transformed between a general-purpose terminal and a members-only terminal. A content reproduction terminal 30a is composed of: an IC card slot into which a card 20a distributed to a membership user is to be inserted; an application/display-data acquisition unit 304a which sets the operation mode on the basis of a membership certificate 2020 showing a group, to which the user belongs, held previously in the card 20a; and a resident player application execution unit 305a and a member player application execution unit 308a which reproduce the content differently depending on the setting result given by the application/display-data acquisition unit 304a.
