Abstract:
A protected content distribution system utilizes media-based copy protection to support online distribution of protected content in a secure and legitimate fashion. Using a media-based copy protection scheme based on broadcast encryption, the protected content distribution system realizes online distribution of protected content such as, for example audio files, movies, etc, authorizing consumption of unlicensed content by transfer of a unique encrypted key to the protected media. This transaction is fast, involving the transfer of an encrypted binding key rather than the protected content. Content is enabled through a unique encrypted key on protected media accessed through a device separate from the media driver.
