脆弱性数字文档水印技术

On Fragile Document Watermarking Technique

网络和信息技术的发展,使得大量的纸质文档可以以数字文档形式进行保存和传输,于是如何保证数字文档的真实性和完整性成为一个急需解决的问题.脆弱性文档水印技术的发展,为解决这一问题提供了重要途径.该文介绍脆弱性数字文档水印的基本概念和研究现状,重点分析脆弱性文档水印各种算法,比较其优缺点;最后指出了脆弱性数字文档水印技术今后的发展方向.

With the development of the network and information technologies, many paper documents can be saved and transformed in digital form. So how to protect the truth and the integrity of the digital documents is in dire need. The development of the fragile text watermarking technique provides an important method to resolve this issue. In this paper, the concept of the fragile document watermarking is introduced and the curium research states are studied, with emphasis on the existing algorithms and the comparisons of their advantages and disadvantages. Finally the authors point out the future research directions for fragile document watermarking techniques.
