摘要： [Object] To generate content in which it is possible to analyze a source of illegally copied content or the like, and make normal reproduction possible without a pause in reproduction in a reproduction device.
[Solution] Content including an individual segment region formed of a plurality of variation data in which identification information different from each other is embedded and each of which can be decrypted by a different key, and a common segment region is used. The variation data is formed of a 6144-byte aligned unit. A reproduction device calculates a reproduction path by applying a device key, and selects an aligned unit corresponding to the reproduction path from an aligned unit configuring variation data in an individual segment region, and then, executes decryption and reproduction processing.摘要翻译： [对象]生成可以分析非法复制的内容等的来源的内容，并且可以在再现设备中的再现中没有暂停的情况下进行正常再现。 [解决方案]包括由彼此不同的标识信息被嵌入并且每个可以通过不同的密钥解密的多个变体数据形成的单独片段区域的内容以及公共片段区域被使用。 变体数据由6144字节对齐的单位组成。 再现设备通过应用设备密钥来计算再现路径，并且从配置单个分段区域中的变化数据的对齐单元中选择与再现路径对应的对齐单元，然后执行解密和再现处理。

摘要： Update of a master key and a media key is transmitted along with a key update block (KRB) through a key distribution system of tree structure. The KRB has a structure where devices constituting leaves of the tree have a leaf key and a limited node key and creates and distributes a specific key update block (KRB) to a group specified by a specific node, thereby limiting updateable devices. Any device not belonging to the group cannot decode the data, thus ensuring the safety of key distribution. Especially, in a system using a master key under generation control, an update master key is distributed by a KRB.

摘要： In a tree-structural key distribution system, renewed data of a master key and medium key are sent along with a key renewal block (KRB). KRB is such that each of devices included as leaves of a tree structure has a leaf key and restricted node key. A specific KRB can be generated for a group identified by a specific node and distributed to the group to restrict a device for which the key can be renewed. Any device not belonging to the group cannot decrypt the key, whereby the security of key distribution can be assured. Especially in a system using a generation-managed master key, a master key renewed with KRB can be distributed.

摘要： An information processing system and method are disclosed in which information processing is performed in a highly efficient manner using an enabling key block (EKB) on the basis of a tree structure including category subtrees. A key tree is formed so as to include a plurality of subtrees serving as category trees categorized in accordance with categories and managed by category entities. An EKB including data produced by selecting a path in a tree and encrypting a higher-level key in the selected path using a lower-level key in the selected path. The resultant EKB is provided to a device. Distribution of EKB's is managed on the basis of an EKB type definition list representing the correspondence between an EKB type identifier and one or more identification data identifying one or more category trees that can process an EKB of an EKB type specified by the EKB type identifier.

摘要： In a process for manufacturing an information recording medium, a configuration is provided in which strict information management and an information recording medium manufacturing process are realized. In a configuration in which master data as original data of recording data for an information recording medium is generated and recording data for the information recording medium is generated on the basis of the master data, master data containing a dummy data area in a partial area of the master data is generated, and the dummy data area is identified and a process for setting significant information is performed on the basis of the stored information of an auxiliary file. Therefore, it is not necessary to obtain data of significant information when the master data is to be generated, and it becomes possible to generate the master data without obtaining specific information, such as an encrypted key block.

摘要： An information reproducing method and an information reproducing device in which the key renewal block (KRB) of the latest verison is selectively used to encrypt the content to store the encrypted contents in a recording medium. A plural num er of KRBs of different generations and versions are stored in a recording medium. If the latest KRB is detected, it is stored in a memory unit within the recording and/or reproducing device. A plural number of KRBs having plural different generations or versions are stored on the recording medium. With the present method and device, in storing the content in the recording medium, the latest usable one of the KRB in the memory unit of the reproducing device and plural KRBs on the recording medium is detected to acquire an encrypting key, such as a media key, to execute the content encryption. In this manner, the encrypted content based on a KRB of a newer version can at all times be stored on the recording medium.

摘要： A configuration in which usage control that is substantially similar to content usage control in a copy source medium can be performed in a content copy destination is implemented. A data processing unit that performs a copy process of recording data recorded on a first medium on a second medium records encrypted content in the first medium on the second medium, without decrypting the encrypted content. In addition, the data processing unit converts a CPS unit key file recorded on the first medium to generate a converted CPS unit key file and records the converted CPS unit key file on the second medium. Further, the data processing unit acquires an MKB not requiring KCD, which is capable of directly calculating a media key using only a device key, without using key conversion data (KCD) recorded on the first medium, from a server and records the MKB not requiring KCD on the second medium.
