Abstract
Abstract A secure digital data distribution system ( 100 ) for preventing unauthorized access to digital data. The system utilizes an identification system module ( 116 ) embedded in a digital storage media ( 114 ) to grant authorization to media players ( 118 ). Prior to reading the digital data recorded on the media ( 114 ), an identification system interrogator ( 122 ) reads authorization data from the identification system module ( 116 ) to determine whether the media player ( 118 ) is authorized to read the media ( 114 ). If the authorization data matches the media player's unique identifier, authorization is granted and the media player ( 118 ) commences to read the media ( 114 ).
