| 摘 要： | 本文提出了一种基于混沌加密和Arnold置乱的数字水印算法,将含有版权标志信息的二值图像作为水印,用双混沌序列对其进行加密,用改进的Arnold变换对其进行置乱。在小波信号的低频处嵌入水印,提高了水印的鲁棒性。实验证明该算法是十分有效的。

| Abstract: | This paper discussed the digital watermark algorithm based on chaotic system-encrypting and Arnold scrambling.In the algorithm,it took the meaningful binary image with the copyright information as the watermark and encrypted the watermark with the chaotic sequences and scrambled the watermark with improved Arnold transform method.It embeded the watermark in the wavelet domain and had better robust.In the experiment,it was proved that the algorithm was better. |
