The Relationship

Many audio watermarking techniques presented in the last years make use of masking and psychological models derived from signal processing. Such a basic idea is winning because it guarantees a high level of robustness and bandwidth of the watermark as well as fidelity of the watermarked signal. This chapter first describes the relationship between digital right management, intellectual property, and use of watermarking techniques. Then, the crossing use of watermarking and masking models is detailed, providing schemes, examples, and references. Finally, the authors present two strategies that make use of a masking model, applied to a classic watermarking technique. The joint use of classic frameworks and masking models seems to be one of the trends for the future of research in watermarking. Several tests on the proposed strategies with the state of the art are also offered to give an idea of how to assess the effectiveness of a watermarking technique.

This paper describes the agent technology and the concept of digital watermarking and the specific properties of watermarking techniques forced by the copyright protection applications. For digital copyrights protection in heterogeneous network environment, intelligent Agent technology is introduced to combine with digital watermarking technology. It proposes a framework model of Digital Right Management (DRM) system based on the agent technology and digital watermarking techniques and detailedly discusses functions and working principle of intelligent Digital Right Management(DRM) system.
