Research of digital watermark´s relationship algorithm against interpretation attack

Firstly, the interpretation attack is analyzed deeply, the Embedding is ruled by the digital watermark´s relationship, And a way to create relationship are proposed, which bases on the interrelation of information. Then the construction and transmitting model of relationship algorithm is established, And on the base of that, the restriction process of digital watermark´s relationship to interpretation attack is analyzed deeply. Finally, after testing and analyzing, it is proved again that interpretation attack can be avoided by digital watermark´s relationship, at the same time, digital works can be protected and transmitted trace effectively.
