Digital Rights Management (DRM) is the persistent access control of digital content. This paper examines the implications of enforcing access control rules at the operating system kernel level. We describe our design for a prototype, operating system kernel level DRM Controller. Initial performance benchmarks measuring access time have yielded promising results. Only negligible overhead was measured unprotected data, while the overhead incurred for protected data is unnoticeable to a human user. Lastly, we discuss implications of operating system level DRM.
