Joint Fingerprinting and Encryption in the DWT Domain for Secure M2M Communication

Machine-to-machine (M2M) communication is viewed as one of the next frontiers in wireless communications. Because of unguarded communication, new security threats emerge. Considering that multimedia will be widely used in various applications over M2M network, it is very urgent to meet new security requirements for multimedia communication. This paper focuses on a joint fingerprinting and encryption (JFE) scheme in the DWT domain with the purpose of protecting multimedia distribution. A multimedia encryption scheme is first to scramble the multimedia content before distribution, and the fingerprinting scheme is then introduced to provide further protection. The goal of the proposed content distribution scheme is to provide secure content communication and deter the device from illegally redistributing the content. The proposed method, to the best of our knowledge, is the first JFE method in the DWT domain for secure M2M communication. The use of fingerprinting along with encryption can provide a doublelayer of protection to digital media. Theory analysis and experimental results show the effectiveness of the proposed scheme.
