The widespread use of image audio and video data makes media content protection increasingly necessary and urgent. For maximum safety it is no longer sufficient to merely control access rights. In order to fully protect multimedia data from piracy or unauthorized use it must be secured through encryption prior to its transmission or distribution. Multimedia Content Encryption: Techniques and Applications presents the latest research results in this dynamic field. The book begins with the history of multimedia encryption and then examines general performance requirements of encryption and fundamental encrypting techniques. It discusses common techniques of complete partial and compression-combined encryption; as well as the more specialized forms including perception scalable and commutative encryption. In addition the author reviews watermarking and joint fingerprint embedding and decryption. Later chapters discuss typical attacks on multimedia encryption as well as the principles for designing secure algorithms and various applications. An exploration of open issues up-and-coming topics and areas for further research rounds out the coverage. Shiguo Lian is the author or co-author of more than fifty peer-reviewed journal and conference articles covering topics of network security and multimedia content protection including cryptography secure P2P content sharing digital rights management (DRM) encryption watermarking digital fingerprinting and authentication. By following the techniques outlined in this book users will be better able to protect the integrity of their multimedia data and develop greater confidence that their data will not be misappropriated. .
