| 摘 要： | 提出了一种图像多功能数字水印算法.在图像中同时嵌入一个鲁棒水印和一个脆弱水印,前者用于版权保护,后者用于篡改提示.结果表明,鲁棒水印对各种攻击具有一定的稳健性,而脆弱水印具有一定的易损性,从而实现了版权保护和篡改提示,而且有效实现了原始水印的盲检测.

| Abstract: | Presented a multipurpose image watermarking algorithm.The watermarking algorithm embedded both robust watermark and fragile watermark to achieve the goal of image content authentication and alteration hint simultaneously.The experimental results demonstrated that the robust watermark was robust to many attacks and the fragile watermark was fragile,so it has realized the image copyright protection and alteration hint.It also realized the blind detection of original watermarking effectively. |
