摘要： To provide a content playback device that can use content appropriately by avoiding output of content not permitted to be used according to contract information. A playback control unit 102 extracts a content name from playback control information in a playback path information table 210, and inquires of a rights management unit 108 whether content identified by the extracted content name is playable or not. If the content is judged as being unplayable, the playback control unit 102 extracts an alternative playback number from the playback control information, and extracts a content name from playback control information whose playback number matches the alternative playback number. The playback control unit 102 then instructs a decryption unit 103 and a playback unit 107 to decrypt and play back encrypted content identified by the extracted content name.

摘要： An executing device for conducting playback is high during the playback of contents. The executing device is equipped with a highly efficient processor and reduces the processing load involved in verification by using, for the verification, only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on a DVD. In addition, the executing device is capable of improving the accuracy of detecting unauthorized contents by randomly selecting a predetermined number of encrypted units every time the verification is performed.
摘要翻译： 在播放内容期间，用于进行播放的执行装置很高。 执行装置配备有高效的处理器，并且通过仅使用构成在DVD上记录的加密内容的多个加密单位随机选择的预定数量的加密单元来验证，来降低验证所涉及的处理负担。 此外，执行装置能够通过在每次执行验证时随机选择预定数量的加密单元来提高检测未授权内容的准确性。

摘要： 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 consisting 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.

摘要： A content protection data processing system and a playback device determine whether to permit playback of a content recorded in a recording medium, based on a type of the recording medium and a signature type of a signature attached to a program. Additionally, the content protection data processing system and the playback device switch a procedure relating to a digital signature for each signature type of the digital signature, which enables both the protection of the copyright of the content and the efficient manufacturing of commercial ROM media.

摘要： If playback devices are prohibited from playing back contents recorded in R media, there occurs a problem that it takes more time to manufacture commercial ROM media. Conversely, if playback devices are permitted to play back contents recorded in R media, there occurs a problem that copyrights might be infringed. In view of these, the aim of the present invention is to provide a content protection data processing system and a playback device capable of determining whether to permit playback of a content recorded in a recording medium, based on a medium type of the recording medium and a signature type of a signature attached to a program, and switching a procedure relating to a digital signature for each signature type of the digital signature. This enables both the protection of the copyright of the content and the efficient manufacturing of commercial ROM media.

摘要： An incentive provision system that contributes to expanded sales of a content service and includes a user terminal and a provision device. The provision device receives, from the user terminal, request information for requesting incentive information relating to the content service. If the request information is valid, then the provision device provides the incentive information to the user terminal. A user of the user terminal enjoys using the incentive information provided from the provision device, which, in turn, motivates the user to receive the content service.
