摘要： PROBLEM TO BE SOLVED: To solve the problem that an executing device for executing playback has to be equipped with a high-performance processor, because verification of correctness of information is executed in parallel with the playback of the content, and therefore processing load becomes high during the content playback. SOLUTION: The processing load involved in processing of verification is reduced by using, for the verification, only a predetermined number of encrypted units selected randomly from among a plurality of encrypted units constituting encrypted contents recorded on a DVD. Further, the accuracy of detecting unauthorized content can be improved to some extent by randomly selecting the predetermined number of encrypted units every time the verification is performed.

摘要： PROBLEM TO BE SOLVED: To collect the use result or the like of contents in a user terminal from a right management server at optional timing. SOLUTION: In the right management server 100, a license data generating/updating part 307 generates license data 900 including use conditions 503 for permitting the use of contents based on the contents use right 500 of a user. A subset use condition setting part 308 sets subset use conditions 901 for temporarily invalidating the license data 900, to the license data 900. A communication part 311 transmits the license data with the subset use conditions 901 set, to the user terminal 110 and receives the license data 900 returned from the user terminal 110. Upon receiving the invalidated license data 900, the license data generating/updating part 307 releases invalidation by updating the subset use conditions 901. COPYRIGHT: (C)2005,JPO&NCIPI
