Cryptanalysis and improvement of biometric based content distribution framework for digital rights management systems

Abstract

Digital contents are utilized and transmitted over the public network. Thus, the evolution of an emphatic mechanism to ensure authorized access to digital content is the topmost priority of the multimedia industry. Digital right management (DRM) is a tool that aims to ensure authorized access multimedia content to the right holders. However, over the years, several other challenges associated with DRM systems have also emerged such as efficient computation, user privacy, the security of existing protocols. For the scalable distribute digital content, an efficient, secure and authorized content distribution protocol is required. This paper proposed a biometric‐based content technique for a DRM system, which enables to deliver content key among mutually authentic entities. The security of the proposed protocol has been proved under the widely recognized random oracle model, which indicates that the proposed protocol is provably secure under probabilistic polynomial time adversary. The proposed scheme achieves anonymity and unlinkability. Moreover, comparative analysis shows that the proposed scheme address efficiency along with security.
