摘　　要：计算机互联网技术的飞速发展促使数字信息在网络信息系统上的分发、复制和处理变得很容易。然而,这同样使得拷贝那些版权保护的信息也变得相当容易,而且几乎不用支付任何费用。作为信息隐藏技术的一个重要分支,数字水印技术将成为保护数字作品版权的重要手段。本文对多媒体数字水印技术的原理及其基本特征、现有方法作了详细的论述,重点分析了几种数字水印算法方案和攻击手段,指出了应用中存在的问题,并展望了未来研究方向。With the advances in computer technology and the development of the Web, digital date facilitates efficient distri- bution,reproduction and manipulation over networked information systems. However, these efficiencies also enable the per- fect copying and distribution of copyrighted material to almost anywhere in the world at almost no cost. As a important branch of information hiding, digital watermarking has become an essential way to protect digital copyright. This paper pre- sents details of the principle, fundamental characteristics, existing algorithms and application fields of digital watermarking, makes emphasis on the analysis on several digital watermarking algorithms and its attack way, points out some problems in application, and foresights the future research prospect.
