Abstract


With the rapid development of information and network technology , the traditional means of information exchange has changed dramatically , the growing popularity of multimedia digital information by virtue of its convenient and faster mode of transmission , along with the copyright issues are also increasingly serious . Lack of appropriate protection mechanisms , the digital information can easily be copied , tampering and forwards against the legitimate interests of the copyright owner , and thus more and more attention has been paid for the copyright protection of multimedia digital information . In order to solve this problem have been proposed digital rights management technology , the technology has become a hot research countries . Firstly, the theory and technology of multimedia copyright protection analysis and research. Key in the digital rights management technology - digital watermarking technology in digital rights discourse . Requirements for copyright protection , and a typical digital rights management systems and digital watermarking technology is designed and implemented a rights management protocol system based on digital watermarking . Proposed and implemented a visual watermark invisible watermark combined dual watermark algorithm effective protection of multimedia digital information plays a role in the study based on the characteristics of the image content based on robust watermarking .
