DRM Content Adaptation Between Different DRM Systems for Seamless Content Service

DRM is a technology to protect digital contents from unauthorized access and to control the way a user consumes his content. Although modern DRM technologies carry out their duty very well as a protector of copyrighted contents but users face different problem, inconvenience due to the lack of interoperability between DRM systems. We have suggested a scheme to exchange DRM-protected contents between heterogeneous DRM systems by providing content exchange format not bound to specific DRM system. In this paper, we address the limitations of previous work and suggest a new content exchange scheme to solve the problem.
