摘要

首先介绍了数字水印的基本原理并对图像数字水印技术进行了总结

然后提出了一种改进的基于离散Haar小波变换和量化编码的敏感数字水印技术.针对原技术的缺陷

在改进技术中

离散Haar小波变换没有进行归一化处理;此外

对量化函数和水印嵌入公式进行了修改.理论和实验证明

这些改进使得该敏感数字水印技术可以更容易地实现

消除了原有的缺陷.最后

结合纠错编码技术提出了一种在验证水印时无需原水印信息的方法.

Abstract

This paper firstly introduces the principle of watermark and summarizes the techniques of image watermark. Then an improved fragile watermark technique is presented

where Haar wavelet transform does not involve normalization

and quantization function is mended

watermark embedding equation is also improved. With these improvements

the watermark technique does work precisely. Using the error control code

fragile watermark detection can be done without original watermark.
