摘要
该文基于零水印原理,采用文本中两个多音字之间的汉字以及多音字的读音特性来构造零水印,提出一种基于多音字特征的中文文本篡改检测水印算法。仿真实验表明,该算法产生的水印不仅具有较好的不可见性和鲁棒性,同时还能识别定位出对文本内容的删除、添加和替换等的攻击。
Based on the principle of zero-watermarking,this paper adopts the pronunciation of polyphone characters and the features between two polyphones of Chinese characters to construct the zero-watermarking algorithm,and produces a Chinese text watermarking algorithm for tamper detection based on polyphone.Simulation results show that the algorithm not only meets with better invisibility and robustness,but can identify the attacks of deleting,adding and replacing characters.
