An application, media drive, and media are configured so as to cooperate with one another to provide secure access and copying of protected content on the media. The application cooperates with the media drive to identify the media as a cooperating component, and in the process, also identifies the media drive as a cooperating component. The media includes information facilitating such identifying activity, such as a fingerprint indicating the copy protection method used to protect the content. Also included on the media is a guard module that authenticates the application as a cooperating component, establishes secure channels respectively with the application and the media drive for communicating secret information, installs licenses included on the media, and only allows access to the protected content if the media is an original copy. The application then manages usage and/or copying of the protected content according to the installed licenses.

A system and method for licensing content on an updated storage media is provided where new licensed content is downloaded and stored onto the updatable storage media containing licensing rights. The licensing rights are stored in a SMLD on the storage media. The rights will be authenticated by a rights management server somewhere on the Internet. If the rights management server determines that a user has rights to the new content, then the user is allowed to access and download the new content from a content server. The present invention may be utilized in various industries such as music, film, B2B, education, and television and may be embodied on various media such as DVD storage media, CD storage media, and hybrid optical disk media.

The information reproduction device for reproducing the contents information based on the license information added to the contents information and required for reproducing the contents information, includes a determining section for determining whether the encrypted contents information is the officially copied contents information or privately copied contents information based on the contents of the license information, and a reproduction section configured to reproduce the contents information determined as the privately copied contents information by the determining section under more severer restrictions than the officially copied contents information. Thus, the contents copied by the proper route (officially copied contents) can be distributed in a more advantageous form than the contents copied without proper authorization.

A copyright protection system includes a recording device and a reproduction device. The recording device writes encrypted content, an encrypted content key for decrypting the encrypted content, and license information on a recording medium on which a unique media number has been recorded in an unrewritable state. The license information is generated using both the media number and the encrypted content key, and therefore reflects both values. The reproduction device reads the media number, the encrypted content key, and the license information from the recording medium, and judges whether the license information reflects both the media number and the encrypted content key. Only if the license information reflects both values, the reproduction device decrypts the encrypted content key, and decrypts the encrypted content using the content key. In this way, the copyright protection system allows only original recording media to be reproduced, and prohibits reproduction of copy recording media.

摘要:
An information recording apparatus comprises an encryption section encrypting contents information and also a license condition referred to to limit use of the contents information and a decoding key for decoding the encrypted contents information to generate license information, and a recording section recording the encrypted contents information and the generated license information on a recording medium. An information reproducing apparatus comprises a decoder unit decoding the license information recorded on the recording medium using a second decoding key for decoding the license information and deciding on the basis of the license condition contained in the decoded license information whether the contents information can be used. If it is decided that the contents information can be used, the encrypted contents information recorded on the recording medium is decoded using the first decoding key contained in the decoded license information.
