| Abstract: | In this paper,a digital watermarking method in mixed transform embedded with chaos scrambling was proposed.By this way,watermarking can be detected and extracted without the original image,and coding based on chaos keeps secrets better.The experiment results indicate that the proposed method can be realized easily,which keeps and hides the watermarking information better.The proposed method performs well in encountering with overall or local attacks. |
