Security and rights management in digital cinema

This paper provides an overview of digital cinema including some of the architectural ideas that have been proposed and are being considered. There are a number of security tools that can be used with the goal of secure delivery of motion picture content to the projector. There are many technical and business constraints that guide these designs. Independently, there have been a number of efforts in the watermarking community to attach forensic tracking information to the motion picture content. Such information would provide persistent tracking beyond the projector and would be useful in identifying compromised equipment.
