Abstract
As the number of digital content service providers increases, a variety of digital rights management (DRM) systems appear without supporting interoperability. The lack of interoperability in DRM systems causes inconvenience to customers, especially when they want to play content through multiple devices manufactured by different vendors. In this letter, we propose a novel method to support interoperability between different DRM systems. The proposed technique aims to build an open framework structure which satisfies DRM vendors' requirements by enhancing the security of intellectual property management and the protection tools.
