Identity Based Drm System with Total Anonymity and Device Flexibility Using Ibes

Most of the Digital Rights Management (DRM) systems fail to cover all requirements like user anonymity, user fairness, security and others. Device based DRM systems, adopted by most providers, lack user fairness and mostly follow proprietary formats. On the contrary, Smart Card DRM systems satisfy user anonymity and fairness, but have certain vulnerabilities, as identified in this paper. We propose a DRM system using Identity Based Encryption System (IBES) that overcomes the deficiencies and vulnerabilities of the existing DRM systems. The proposed DRM system is an approach towards an open framework, wherein, the content processing application can be independent of the DRM provider, and the security is controlled with the help of the smart cards.
