Abstract: PROBLEM TO BE SOLVED: To provide configurations to control use of contents according to a time stamp. SOLUTION: In reference to a certificate revocation list (CRL) including invalidation information of a content owner providing the content, verification is performed on whether content-owner identification recorded a content-owner certificate recorded on the disc is included in the certificate revocation list (CRL). If the content-owner identification is included in the list, comparison is performed between a time stamp stored in the content certificate and a time stamp in the certificate revocation list (CRL). If the content-certificate time stamp has date-and-time data not earlier than the CRL time stamp, use of the content is controlled to be prohibited or restricted. COPYRIGHT: (C)2009,JPO&INPIT
