Network-based usage monitoring and rights management of digital media

This paper proposes a new method to enhance digital media protection over the internet. The major obstacle while developing a Digital Rights Management (DRM) system is the lack of available trusted viewers. Using the newly proposed method, the digital content is decrypted only when the client machine is under controlling and monitoring of the server. The client-side and server-side program works together to ensure the safety of the system. Any malicious action once detected, the server can order the client-side management program to close the digital media immediately.
