Applications for robust watermarking is one of the major branches in digital rights management (DRM) systems. Based on existing experiences to assess how good one robust watermarking is, it is generally agreed that three parameters or requirements, including the quality of watermarked contents, the survivability of extracted watermark after deliberate or unintentional attacks, and the number of bits embedded, need to be considered. However, performances relating to these three parameters conflict with each other, and the trade off must be searched for. In this chapter, we take these requirements into consideration, and we can find the optimized combination among the three parameters. With the aid of genetic algorithm, we design an applicable system that would obtain the good quality, acceptable survivability, and reasonable capacity after watermarking. Simulation results present the effectiveness in practical implementation and possible application of the proposed algorithm.
