Abstract: An information processing device, method, recording medium, and program capable of managing use state information necessary for using a content for each service. The use state information is correlated to a content ID (CID) and a use right ID and stored in a service node management area so as to be managed. As has been described above, since the use state information is managed for each service, even if one use state information is broken or altered, i.e., rewritten, its affect can be stopped within one management area. That is, it becomes impossible to use a content whose use state information is stored in the management area containing the use state information which has been altered but it is possible to use a content whose use state information is stored in another management area. The present invention may be applied to a personal computer.

Abstract: The present invention relates to an information managing apparatus and method, a recording medium, and a program in which unauthorized use of content can be prevented. A ripping module 91 of a client 1 retrieves the content recorded on a CD 81. In the client 1, a content ID for identifying the content and a unique ID unique to the client 1 are generated, and these IDs are added to the content retrieved by the ripping module 91. A usage right containing the usage conditions of the content, etc., is generated and saved. The usage right includes information indicating that an apparatus (client) having the same ID to the unique ID added to the content is only allowed to play back the content. The present invention is applicable to an information processing apparatus such as a personal computer.
