Abstract

According to the analysis of the definition and basic characteristics of digital watermarking technology, the system model of digital watermarking is given. The system consists of two modules which are watermark embedding module and watermark detection and extraction module. The experiment result shows that the digital watermark is non-perceptible; the watermark information can be extracted even if it has been attacked, and the expected effect can be achieved. This technique is most useful for copyright protection of digital images.
