摘　　要：针对中文文本的内容认证问题,结合汉字自身的特点,提出一种基于汉字结构知识的文本零水印认证方案.该方案将认证信息嵌入在被构造的二进制模式中,而不是载体文本本身中,适用于长短文本文档,认证过程不需要第三方参与,方案实用性较强.该方案在水印构造与文本认证过程中,采用汉字结构知识和混沌加密算法共同构造二进制模式,安全性较好.Aiming at the problem of content authentication for Chinese text document,combined with the characteristics of Chinese characters,we proposed an authentication scheme of text zerowatermarking based on structure knowledge of Chinese characters.In this scheme,the authentication information was embedded in the constructed binary pattern,but not in the host itself,so it was applicable to short or long text documents simultaneously.The certification process did not need to participate in the third party,the scheme was practical.The binary pattern was constructed by using the structure knowledge of Chinese characters and chaotic encrypting algorithm in the process of watermarking construction and text authentication,and the security of this scheme was better.
