%X A watermarking technique based on the frequency domain is presented in this paper. The one of the basic demands for the robustness in the watermarking mechanism should be able to dispute the JPEG attack since the JPEG is a usually file format for transmitting the digital content on the network. Thus, the proposed algorithm can used to resist the JPEG attach and avoid the some weaknesses of JPEG quantification. And, the information of the original host image and watermark are not needed in the extracting process. In addition, two important but conflicting parameters are adopted to trade-off the qualities between the watermarked image and the retrieve watermark. The experimental results have demonstrated that the proposed scheme has satisfied the basic requirements of watermarking such as robustness and imperceptible.
