Text zero-watermarking algorithm based on chaotic mapping
一种新的基于混沌映射的文本零水印算法

A novel text zero-watermarking algorithm based on chaotic mapping was brought forward.The features of presented method are as follows: First,there are no modifications to the text document among the process of watermarking embedding,thus the watermarking is perceptually invisible.Second,the watermarking is robust against copying,cutting and formatted modifying.Third,the watermarking can be detected only by using a secret key and doesn't need the original text.
