Multimedia Content Protection by Biometrics-Based Scalable Encryption and Watermarking

Abstract

With the huge development of broadband network, distribution of multimedia by means of Internet is an uncomplicated method of communication and data exchange. Intellectual Property (IP) protection is a vital component in a multimedia broadcast system. Traditional IP protection methods can be classified into two major categories: encryption and watermarking. Content protection has turned out to be one of the most considerable and demanding problems of this field. This paper proposes a multimedia content protection framework that is dependent on biometric data of the users, a layered encryption/decryption scheme and watermarking. Scalable encryption algorithms result from a transaction between implementation cost and resulting performances. In addition, this approach generally aims to be exploited competently on a large range of platforms. The computational necessities and applicability of the proposed method are addressed. By utilizing the benefit of the nature of cryptographic schemes and digital watermarking, the copyright of multimedia contents can be protected. In this paper, the scalable transmission technique is utilized over the broadcasting environment for encryption. The embedded watermark can be thus extracted with high confidence.
