摘要： There are provided an information recording medium, and an information processing apparatus and method by which content usage in compliance with copyright protection is made possible in information processing devices such as a CD player and a PC. In the information recording medium, a first data storage area on which a copying prevention process is performed, and a second data storage area in which is stored an encrypted content file containing encrypted content, and encrypted key data such that key data for use in a decryption process is encrypted and which can be decrypted only in a device having a license are set. It becomes possible to play back the recorded content of a first data recording field in a playback device such as a CD player, and even in an information processing device, such as a PC, it is possible to decrypt and play back encrypted content of a second data recording field under the condition of obtaining a license.

摘要： To provide an information recording medium and an information processing apparatus and method in which the content usage by ensuring copyright protection can be implemented both in CD players and information processing apparatuses, for example, PCs. A license providing condition for a client can be dynamically set based on the content usage status of the client. For example, for clients having a large number of content usages, the license price is decreased, or the license can be provided free. A media ID stored in, for example, a CD, and a product ID as an identifier in, for example, a title unit or an album unit are received from the client. Based on such identification data, the content usage status data can be checked. Accordingly, the licenses can be provided under the reliable management of the content usage.

摘要： The present invention relates to an information processing apparatus and method, a recording medium, and a program for allowing items in usage conditions set for digital content to be easily added, deleted, and replaced. A data acquisition section 91 requests a content distribution apparatus to supply digital content, and outputs to a data storage section 95 the digital content and usage-condition information corresponding thereto supplied in response to this request. Furthermore, in response to a request from a usage-condition determination section 93, the data acquisition section 91 makes a request to the content distribution apparatus for a usage-condition plug-in module 94. From among a plurality of usage-condition plug-in modules 94, the usage-condition determination section 93 starts up only usage-condition plug-in modules 94 corresponding to the items in the usage conditions, and informs a playback section 92 of the result of a determination as to whether the items in the usage conditions are satisfied. The playback section 92 plays back the digital content according to the determination result.
