Publication number: 20110119493Abstract: Processing load on an executing device for conducting playback is high during the playback of contents since the executing device performs verification of the contents validity in parallel with the contents playback, and therefore the executing device has to be equipped with a highly efficient processor. The present invention reduces the processing load involved in the verification by using, for the verification, only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on the DVD. In addition, the present invention is capable of improving the accuracy of detecting unauthorized contents to some extent by randomly selecting a predetermined number of encrypted units every time the verification is performed.Type: ApplicationFiled: January 21, 2011Publication date: May 19, 2011Inventors: Masao NONAKA, Yuichi Futa, Toshihisa Nakano, Kaoru Yokota, Motoji Ohmori, Masaya Miyazaki, Masaya Yamamoto, Kaoru Murase, Senichi Onoda

Patent number: 7940935Abstract: A content playback apparatus reduces load concentration on a specific server apparatus that manages content keys of encrypted content, while protecting copyrights of the content. The content apparatus makes playback of content recorded in a recording medium sold possible after the specific server breaks down. A key acquisition control unit (204) reads a playback control information table (211) from a recording medium (102) via a reading unit (201). The key acquisition unit (204) acquires a rights key via a key acquisition intermediation unit (223) from an apparatus specified by an acquisition-destination type and a request-destination type that are stored in the playback control information table (211) and that corresponding to the content to be played. The key acquisition unit (204) generates a content key using the acquired rights key and, when required, a medium key recorded in a medium. A decryption unit (203) decrypts encrypted content using the content key.Type: GrantFiled: June 30, 2005Date of Patent: May 10, 2011Assignee: Panasonic CorporationInventors: Tohru Nakahara, Ryuichi Okamoto, Masaya Yamamoto, Katsumi Tokuda, Masaya Miyazaki, Masayuki Kozuka

Patent number: 7856168Abstract: The recorder/reproducer, when moving a first content data, writes a second content data, which is obtained by re-coding the first content data recorded in a first recording medium, into a second recording medium instead of the first content data, writes one or more first partial information extracted from the first content data into the second recording medium, and makes the first content data irreproducible, using one or more first invalidated partial information having one-to-one correspondence with the extracted one or more first partial information. When restoring the first content data, it makes the irreproducible first content data reproducible, using the one or more first partial information recorded in the second recording medium.Type: GrantFiled: March 11, 2005Date of Patent: December 21, 2010Assignee: Panasonic CorporationInventors: Jun Takahashi, Masaya Miyazaki, Motoji Ohmori, Kaoru Yokota, Toshihisa Nakano, Shunji Harada, Yoshikatsu Ito

Patent number: 7752433Abstract: A content management system formed from a playback apparatus that requests and plays content, and a content management apparatus that manages duplication and deletion of content. The playback apparatus notifies group information of the playback apparatus to the content management apparatus, acquires information from the content management apparatus showing whether requests are permitted, and duplicates/deletes content. By judging whether the playback apparatus belongs to a group, and notifying whether a duplication request is permitted or rejected, based on in-group and out-group remaining numbers that show the remaining number of duplications permitted of apparatuses in-group and out-group, respectively, the content management apparatus relaxes restrictions on in-group content duplication as compared with out-group content duplication, and thus improves convenience for users in a home network, while protecting the rights of copyright holders, with respect to content duplication and usage.Type: GrantFiled: August 28, 2003Date of Patent: July 6, 2010Assignee: Panasonic CorporationInventors: Hiroki Yamauchi, Yuusaku Ohta, Masaya Miyazaki, Natsume Matsuzaki, Toshihisa Abe
