| 摘 要： | 提出了一种基于中国剩余定理的数字水印分存算法.将秘密分存的思想引入到数字水印中,实现了基于部分内容提取水印.该算法具有很好的性能:算法隐藏效果好,凭借肉眼无法看出与原图像的差别;恢复水印时不需要原始图像;在图像受到损坏的情况下,仍可以恢复水印信息;具有很好的安全性,水印的提取受到口令限制.

| Abstract: | A digital watermark sharing algorithm based on Chinese remainder theorem is proposed. This algorithm is mainly used for the copyright protection for the static pictures. The idea of the secret sharing to the digital watermark is introduced, and the watermark recovering based on incomplete content is realized. The algorithm has some good properties. It has a good hiding effect. The difference between the original and the watermarked pictures can not be perceived by eyes. The original picture is not needed in the recover process. The watermark can still be recovered even though the image was damaged. The algorithm has a good security. The recover process is protected by password. Anyone who don't know the password can't recover the watermark. |
