摘要： The present invention provides an information storage medium and a method and apparatus for processing information, which manage information storage media so as to prevent unauthorized copies of contents from being distributed or used. On an information storage medium on which an encrypted content is stored, an information storage medium ID which is an identifier uniquely assigned to an information storage medium, and an information storage medium ID revocation list, which is a list of information storage medium IDs determined as invalid, are further stored. In an information processing apparatus configured to read and play back the content stored on the information storage medium, playback of the content is allowed only when the information storage medium ID stored on the information storage medium is not identical to any of revoked information storage medium IDs described in the information storage medium ID revocation list. This prevents an unauthorized copy of a content from being distributed or used.

摘要： A recording or reproduction apparatus is provided which utilizes copyright information in operations to record content data onto a recording medium or reproduce content data from the recording medium. Copyright information for the contents includes information identifying an input source of the content data. The information identifying an input source is stored in the recording medium along with the content data. When the contents are reproduced from the recording medium, the input source information is acquired and used as a basis for determining whether the contents can be reproduced and output. Thus, it is possible to impose an output restriction on an operation to reproduce the contents in accordance with the input source.

摘要： The invention provides a recording/reproduction apparatus capable of executing accurate and efficient control based on copyright information in operations to record and reproduce contents onto and from a recording medium. Copyright information for the contents includes information on an input source of the contents. The information on an input source is also stored in the recording medium along with the contents. When the contents are reproduced from the recording medium, the information on an input source is acquired and used as a basis for determining whether the contents can be reproduced and output. Thus, it is possible to impose a variety of accurate output restrictions on an operation to reproduce the contents in accordance with the input source. In addition, a key required for generating a MAC (message authentication code) of the copyright information is transmitted to a device along with an enabling key block (EKB) in accordance with a key distribution system based on a tree structure. Thus, only a device having a proper license is capable of carrying out an authentication process using the MAC, making it possible to implement a valid configuration for utilizing the contents.
