    摘要: IC card (300) supplies an encryption key which enables content use, to a terminal apparatus (200) belonging to a domain made up of terminal apparatuses (200) which share the IC card (300). The IC card (300) includes: an extra-domain usage rule holding unit (305) which stores a rule for use of the IC card (300) in a terminal apparatus (200) which is outside of the domain; and an extra-domain use permission judgment unit (309) which judges, according to the usage rule, whether or not use of the IC card (300) is permitted, when the IC card (300) is provided to the terminal apparatus (200). The IC card (300), in addition, supplies the encryption key to the terminal apparatus (200) which is outside of the domain, when the extra-domain use permission judgment unit (309) judges that use is permitted.

    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.
