摘要

数字图像处理技术对图像信息的安全性提出了新的挑战，使得图像认证成为一个亟待解决的问题。数字水印在多媒体信息安全中起着重要的作用。本文提出了一种双重水印定位篡改和自恢复的方法，利用自嵌入技术将特征面隐藏到低频子带LL中以恢复篡改区域。实验结果表明了该算法的有效性。

Dual Watermarking for Image Tamper Detection and Self-Recovery

Digital image processing technology presents new challenges for the security of the image information, which makes image authentication as a problem to be addressed. Digital watermarking plays an important role in multimedia information security. This paper proposed a dual watermarking method to do tamper location and self-recovery, which utilizes self-embedding technology to hide eigenface into the low frequence sub band LL to restore the tamper region. Experimental results show the availability of the proposed algorithm.
