| 摘 要： | 基于政府部门或企事业单位发布的电子文档都是不允许被非法恶意的篡改,本文提出了一种基于汉字次序的文本零水印算法.首先统计电子文档中汉字的出现频次,然后提取高频次和低频次汉字出现的次序作为文档特征来构造零水印.仿真实验结果表明该文本水印算法构造的水印具有很好的透明性,在电子文档受到篡改的情况下,不需要原文档就可以有效地检测出.

| Abstract: | Targetted at demands in government or enterprises fields where electronic documents do not be illegal tampering,a zero-watermark algorithm based on Chinese characters order was presented.In this algorithm,the use frequency of Chinese characters in document was calculated,and then extracting high frequency and low frequency sub-characters’ order to construct a zero-watermark.Simulation results show that the watermark algorithm has good imperceptibleness.And the tampering can be effectively detected wihout the original document. |
