Abstract:
An information processing apparatus for controlling use of a content recorded on a disc. The information processing apparatus includes: in reference to a certificate revocation list including invalidation information of a content owner providing the content, a data verification section verifying whether content-owner identification recorded in a content-owner certificate recorded on the disc as a certificate corresponding to the content owner is included in the certificate revocation list, and if included, the data verification section comparing a content-certificate time stamp which is stored in the content certificate recorded on the disc as a certificate corresponding to the content and a CRL time stamp which is invalidation date-and-time information corresponding to the content owner stored in the certificate revocation list; and a content-use control section prohibiting or restricting use of the content if the content-certificate time stamp has date-and-time data not earlier than the CRL time stamp.
