| 摘 要： | 针对目前半脆弱水印算法在篡改定位和篡改恢复性能方面存在的不足,本文提出了一种高精度图像认证的半脆弱双水印算法。该算法利用认证水印对图像进行认证、定位篡改,利用恢复水印重构被篡改图像。实验结果证明,该算法对图像具有很好的篡改定位能力,并能有效地恢复篡改内容。

| Abstract: | Concerning the shortage of the tamper recovery pedormance in the existing semi-fragile watermarking algorithm, the authors propose a precise two-watermarking algorithm. The algorithm uses the authentication watermarking for image authentication and tamper location; the recovery watermark is tampered image reconstruction. The simulation results show that the proposed algorithm has precise tamper localization, and can effectively recover the tampered content. |
