ABSTRACT:
A copy protection method and a copy protection system are disclosed. The system includes a private key verifier receiving a media certificate that includes a private key identification of a compliant playing device and searching for an actual private key corresponding to the private key identification, an intermediate key decryptor receiving an encrypted intermediate key and decrypting the intermediate key with the actual private key, a media key decryptor obtaining an original media key by decrypting the decrypted intermediate key with a media identification; and a media data decryptor receiving an encrypted media data set and decrypting the media data set with the original media key. The method and system of the present invention are applicable to all types of digital media data, and it makes no assumption of any specific media properties. The primary goal of the present invention is to significantly reduce the possibility of making any illegal copies on any nonstandard equipment and is to restrict the media data transfers only to authorized entities.
