This paper presents a system that provides a data storage area on optical discs which is protected against unauthorized access. The protected area is referred to as a key locker. It is of particular importance to applications that use digital rights management (DRM). An advantage of the key locker concept is its DRM-agnostic nature. As such, any DRM system can benefit from the protected area.
