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 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.
摘要翻译：由于执行装置与内容重放并行地执行内容有效性的验证，所以在内容的重放期间，用于进行再现的执行装置上的处理负载很高，因此执行装置必须配备高效率的处理器。本发明通过仅使用构成在DVD上记录的加密内容的多个加密单元随机选择的预定数量的加密单元来验证验证。此外，本发明能够通过每次执行验证时随机选择预定数量的加密单元，来在一定程度上提高检测未授权内容的准确性。

摘要： When license information is transferred between a server machine (101) and a client machine (103), an identifier which is unique to a series of communication sequences is provided. Such identifier is sent when a communication is performed between such two machines as well as when the license information is updated. Therefore, when a message for transferring the license information is received by the use of the same identifier, a response message is returned without updating the license information.

摘要： A content playback apparatus prevents related content recorded on separate media that make up a virtual package from being played separately, thereby restricting playback of the content to only when the virtual package is assembled as intended by the creator, and protecting copyright of the content. A key obtaining unit obtains a second key, with use of key management information recorded on a recording medium on which related content relating to the encrypted content is also recorded. An information obtaining unit obtains the encrypted content and key generation information that relates to generation of the first key, from a source other than the recording medium. A key generation unit generates the first key with use of the second key and the obtained key generation information. A decryption unit decrypts the encrypted content with use of the first key.

摘要： In a right management server (100), a license data generation/updating unit (307) generates license data (900) including a use condition (503) for permitting a user to use a content based on a content use right (500) owned by the user. A subset use condition setting unit (308) sets a subset use condition (901) for temporarily invalidating the license data (900) in the license data (900). A communication unit (311) transmits the license data (900) in which the subset use condition (901) is set to the user terminal (110), and receives the license data (900) returned from the user terminal (110). Upon receipt of the invalidated license data (900), the license data generation/updating unit (307) cancels the invalidation of the license data (900) by updating the subset use condition (901).
摘要翻译：在权利管理服务器（100）中，许可数据生成/更新单元（307）生成许可数据（900），其包括使用条件（503），用于允许用户基于所拥有的内容使用权（500）使用内容由用户子集使用条件设置单元（308）设置用于临时使许可证数据（900）中的许可数据（900）无效的子集使用条件（901）。通信单元（311）将其中设置了子集使用条件（901）的许可数据（900）发送给用户终端（110），并且接收从用户终端（110）返回的许可证数据（900）。许可证数据生成/更新单元在收到无效许可证数据（900）后，通过更新子集使用条件（901）来取消对许可证数据（900）的无效。

摘要： This invention provides a license information management apparatus and the like that do not require a tamper resistance module with a large memory even in the case where a user possesses a large amount of content. A total control unit (113) specifies a content corresponding to a reproduction instruction received from a user (S202). Further, the total control unit (113) verifies whether or not there is a LT corresponding to the specified content in a secure flash unit (120). In the case where there is the LT in the secure flash unit (120) (S203: Yes) and information concerning the reproduction of the content is received from the content decryption unit (520) (S204: Yes), an encryption/decryption unit (114) decrypts the LT stored in the secure flash unit (120) using a TRM unique key (S205). After that, the encryption/decryption unit (114) updates details of the content reproduction condition information (511a), encrypts the updated details using the TRM unique key, and writes the encrypted TRM unique key into the secure flash unit (120) (S208).

摘要： An information presentation system simplifies entry of information relating to a package media of a user, and management of the information. The information presentation system is made up of a playback apparatus, a library information management apparatus, and a terminal apparatus. The playback apparatus reads an identifier identifying a content from a portable recording medium in which the content is recorded, and transmits the read identifier to the library information management apparatus via a network. The library information management apparatus receives the identifier, acquires attribute information showing attributes of the content identified by the identifier, generates library information including the attribute information and the identifier, and stores the library information. Further, upon request by the terminal apparatus, the library information management apparatus generates presentation information based on the library information, and transmits the presentation information. The user accesses the presentation information using the terminal apparatus.

摘要： A device 201 of a licensee γ generates a release request for a permission to use content data by using a media identifier in a portable recording medium 101 of a licensee β, and forwards the resulting release request to a rights management unit 71. The rights management unit 71 is managing rights information of the content data provided to the licensee β, and based on the rights information together with the release request, generates permission information to allow the portable recording medium 101 to use the content data. Based on the permission information, the rights management unit 71 then generates license information with which the use of the content data in the device connected to the portable recording medium 101 is controlled, and transmits the license information to the device 201. The device 201 then processes the license information to control the use of the content data. In such a manner, provided is a license information management system with which the licensee β can use the content data with his or her own rights information on the device belonging to the licensee γ.
