Methods and systems for controlling the distribution of digital content are provided. A license holder acquires protected content and an original digital license to the protected content from a content provider system. The license holder in turn delegates all or part of the grants in that original license to other qualified devices or clients. The content remains in its original, protected or encrypted form while it is delivered from the license holder to the client along with a digital sublicense that the client receives from the original license holder, whereupon the content can then be rendered. The original digital license defines or governs the conditions under which such delegation occurs, and includes terms under which such delegation is permitted to continue in order to enforce the intent of the content provider.

摘要:
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.

The present invention relates to an information processing apparatus, an information processing method, a recording medium, and a program for importing and exporting a content with information missing controlled. A CPU extracts a sound track contained in the content in step S301, and converts a format of the extracted sound track into a format compatible with a memory stick in step S302. The CPU generates a predetermined file from data contained in the content and excluding the sound track in step S304. In step S306, the CPU attaches reference information of the sound track to the file. In step S307, the CPU controls the writing of the sound track in the converted format and the file to the memory stick. The present invention is applied to clients of a DRM system.

摘要:
The present invention relates to an information processing apparatus and method, a program storage medium, and a program for distributing usage rights for individual smaller details without placing a burden on a client. A usage right held by a content holder server 6 is provided to a license server 4. The license server 4 divides the usage right provided by the content holder server 6 into, for example, a playback-only usage right and a playback-and-checkout usage right. A client 1 pays 10 yen to obtain the playback usage right. The client 1 pays additional 30 yen to obtain the playback-and-checkout usage right. In other words, the playback-only usage right is upgraded to the playback-and-checkout usage right. The present invention is applicable to a server for providing content via a network.
