Application of genetic algorithm on digital watermark against geometric attacks
Against geometric attacks and Contradiction of robustness and invisibility were the chronic problem in watermark algorithm. This paper solves problem of against geometric attacks by blocked carrier image and embedded watermark following the specific sequence, and adopts the genetic algorithm to optimize embedding strength to reach comprehensive optimizing of robustness and invisibility. The result illustrated that the watermark algorithm has sound ability of against geometric attacks, higher security and has good robustness and invisibility as well.
