Abstract

In order to increase the speed of genetic watermarking and improve the robustness and imperceptibleness of the algorithm, a new embedding and extracting method with genetic algorithm (GA) was proposed. The AC coefficients of image in DCT domain were modified to embed the watermark. The proposed embedding and extracting method was employed to accelerate the genetic watermarking and to avoid the leak of watermark. GA was used to optimize both the fundamentally conflicting requirements: robustness and invisibility. The experimental results show both the good robustness under attacks and the high fidelity. The time needed to perform the program is greatly decreased. About 1/3 time has been saved
