Research on Application of Immune Digital Watermark Algorithm

Immune digital watermarking algorithm is a new kind of weak reversible digital watermarking. Accordance with the characteristics of watermark protection, in some cases, it do not expect reversible digital watermark which containing watermarked information will be fully restored to the original undifferentiated state, but it allows some small differences. Under this premise, this paper presents a digital watermark to achieve new ideas for embedding down to the quality of work after the loss of use value, so the embedded watermark of public works on the attackers did not use value if the user is authorized, it can be the resumption of public works receive high-definition works. The watermark technology works because the public can not be used, making the attacks lost their offensive value, even if under attack, the attack destroyed the works since the resumption of code, it will not be high fidelity works. The digital watermark has natural immunity. It is effectively curb illegal copying and tampering to direct and effective protection of digital products.
