数字水印是数字产品产权保护的技术，是当前国际学术界研究的热点问题之一，它包
括算法设计和攻击技术两方面，作为矛和盾的双方，既互相对立又相互促进，而当前的水印方案大都采用传统的攻击手段检验其鲁棒性，对攻击的研究较少。本文从理论上提出了一种基于盲信号分离技术的水印攻击方法，描述了其技术特点，并建立了相应的应用模型，可以推断，新方法的使用会对改进水印算法和水印检测的研究起到良好的作用。

Abstract:Much attention has been paid to digital watermark which is used to protect the property f data products .Technically, algorithm model and attack pattern are necessary in watermark esigning,these two parts restrain and promot each other.Generally,conventional attack patterns re chosen to test watermark,however,it is turely helpful for watermark to experience with more ttacks to gain the real robustness.This paper proposed a new approach to watermark attack which s based on the blind signal separation,we described its characteristics and put up a applicable odel ,all these may have a good effect on the watermark studies henceforth .
