摘要： An information processing apparatus and method prevent the use of content by any unauthorized third parties and enable content to be used on any desired information processing apparatuses. An approval server receives data for identifying a content management program from a personal computer, generates a group key which is shared in a group, stores the data and the group key as related with each other, and transmits the group key to the personal computer.

摘要： An information processing system and method using an encryption key block sets sub-trees classified based on data processing ability of the devices (capability) in a key tree in which respective keys are corresponded to a root, nodes and leaves of a tree in which a plurality of devices are constituted as the leaves, generates a sub-enabling key block which is effective for an entity in a managing subject of each sub-tree (entity), and generates an enabling key block decodable only by the entities having common capability. Also, an information processing system and method using an encryption key block manages a partial tree of a key tree (sub-tree), generates a sub-enabling key block based only on a key set corresponding to nodes or leaves included in the sub-tree, and generates an enabling key block decodable only by selected entities by using the sub-enabling key block. Thus, it is possible to generate and distribute an enabling key block corresponding to data processing ability of a device and to manage devices by dividing a hierarchical key tree structure.
摘要翻译：使用加密密钥块的信息处理系统和方法基于密钥树中的设备（能力）的数据处理能力分类的子树，其中各个密钥对应于树的根，节点和树叶，其中多个设备被构成为叶子，生成对于每个子树（实体）的管理对象中的实体有效的子启用密钥块，并且生成仅能够由具有共同能力的实体解码的启用密钥块。此外，使用加密密钥块的信息处理系统和方法管理密钥树（子树）的部分树，仅基于与包括在子树中的节点或叶子相对应的密钥集来生成子启用密钥块，并且通过使用子启用密钥块来生成仅由选择的实体可解码的启用密钥块。因此，可以生成并分配与设备的数据处理能力相对应的启用密钥块，并且通过划分分层密钥树结构来管理设备。

摘要： Service data or usage right information, used as purchased content or license information, is set so as to be re-acquired on condition that an acquirer is an authorized content-purchasing client. A leaf ID as a client identifier in an enabling-key-block distribution tree, and a restoring-processing requesting file including verification data for the leaf ID are used as client identifying data, whereby it is ensured that an authorized content-purchasing client is verified.
摘要翻译：用作购买内容或许可证信息的服务数据或使用权信息被设置为在收购方是授权内容购买客户端的条件下重新获取。作为启用密钥块分发树中的客户端标识符的叶ID和包括叶ID验证数据的恢复处理请求文件被用作客户端标识数据，从而确保授权内容购买客户端是验证。

摘要： On receiving from a personal computer (1) a request for transmitting data for displaying a picture for inputting a user's profile in association with an MGID and an APID for specifying the personal computer (1), an EMD registration server (3) selects data recorded in correspondence to the APID based on the received APID and transmits the selected data to the personal computer (1). The EMD registration server (3) receivers the user's profile inputted based on the data from the personal computer (1) and records the user's profile in correspondence to the MGID.
