Paper Abstract

This paper presents a private and lossless digital image watermarking system. First, to ensure the security of the watermark, the watermark image is scrambled before embedding. And then, Human Visual System (HVS) is employed to further enhance the transparence and the robustness of the watermarking system. Thirdly, the watermark image is compressed as watermarking information and is embedded in the DCT domain of the original image. Finally, We save the decimal fractions of the image-signed as a data file as a key during embedding and the data file can avoid the decimal fractions data loss caused by saving the image-signed. The experimental results show that it can embed the image as the watermark with strong robustness.
