基于矢量图形的中文文本零水印算法

为了实现中文电子文本的版权保护及防止未经授权的文本信息的扩散,构造了一种基于矢量图形的中文文本零水印方案,并对该方案进行了算法的设计实现.算法以文本主题特征为前提,通过对文本主题特征进行矢量化处理为基础,最终来完成中文文本的零水印构造.最后通过仿真实验对算法进行了验证,结果表明该算法能有效抵抗文本常规编辑、同义替换等操作,在一定程度上改善了水印的鲁棒性、安全性、抗攻击能力.

A Chinese Texts Zero-Watermarking Algorithm Based on Vector Graphics

In order to protect the copyright of electronic Chinese texts and prevent the information spreading without authorization,the authors of this paper present a Chinese texts zero-watermarking algorithm based on vector graphics.This algorithm is based on a premise that the text has the characteristics of the subject,and constructs the zero-watermark of the Chinese text after the process of the vectorization .The result of the experiment shows that the algorithm can effectively resist conventional editing and synonymous replacement,and improve the robustness,security and anti-attack capability of the watermark to a certain extent.
