Abstract
A Digital Rights Management (DRM) system for distribution of digital content such as audio or video uses a method to enhance security of the content from unauthorized access and use, including access by unauthorized players. The method does not necessarily require a token exchange and thereby minimizes storage demands on the server which distributes the digital content. The system generates and distributes keys for decryption of the digital content whereby the keys are unique to a specific player and user account.
