Application Of Digital Watermarks Techniques In Digital Right Management

With the development of Internet technology and the popularization of multimedia technology, digital media has come into people’s daily life. The network has become the main medium for people to obtain information.How to protect the legitimate rights and interests of the copyright owner is not subject to infringement of social concern. Under this background, the digital watermarking technology emerged, the digital watermarking technology is embedded in the digital media information through a specific algorithm, which requires no impact on the actual application value of the original information, but also the need to extract the embedded watermark information. As the digital watermarking algorithm involves many subjects, the application scope is expanding, it has become a hot spot of domestic and foreign research. In this paper, a new digital watermarking algorithm is proposed based on the previous studies. The work done in this paper is as follows:This paper first introduces the research status and basic knowledge of digital watermarking technology, including the concept, characteristics, classification, application fields and common attacks. In the digital watermarking system, the watermarking image is scrambled by Arnold transform and the DCT transform and the human visual system characteristic. Simulation and verification of the algorithm based on the MATLAB platform. At the end of the paper, the next step is also proposed.
