摘要

本文提出一种新的安全水印嵌入技术:同时对两帧数字图像嵌入两种不同水印

对任意提取一幅图像的水印

无法恢复两个水印的任何信息.在获得双密钥情况下

方可恢复两幅图像的水印.从数学上证明了我们提出的新技术的有效性

并对算法安全性给予了分析.在变换域上给出了实现了双盲水印的算法

采用StirMark水印测试软件进行了一系列攻击性试验

其测试结果表明此技术提供了一种新的数字版权保护的方法.

Abstract

A novel and secure watermark embedding technology is given

which embeds two different watermarks into two digital images. Any information of the two watermarks from any one of the two images can not be obtained. Any information of two water-marks can not be recovered without any one of the two keys or one extracted information of two Stego-images.The validity of the technology is proved with mathematical theory

and the security of the algorithm is also discussed in the paper. The embedding algoritlun of two blind watermarks is given based on transformation domain.Then a series of attacking tests are performed with StirMark software. The test results verify that the validity of the technology.Therefore

the technology provides a new method of copyright protection.
