| Abstract: | The relation between the digital watermarking and spread-spectrum is analyzed at first, the character of chaotic sequence spread spectrum is discussed, and a chaotic sequence spread-spectrum digital watermarking based on the adaptive wavelet transform is proposed. With this scheme computer simulation experimental result has shown that watermarking is invisible, robustness and have blind checking probability. |
