摘    要:在分析现有文本数字水印方法缺陷的基础上,提出了一种新的基于混沌映射的文本零水印算法。实验结果证明算法具有以下性能:加载水印时对文档信息不作任何修改,水印完全不可见;可以有效地抵制针对文本文档的复制、剪切、格式调整等编辑操作,水印具有较强的鲁棒性;检测水印受口令限制且实现了盲检测。

关 键 词:数字水印    零水印    混沌映射

Abstract: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.
Keywords:digit watermarking  zero-watermarking  chaotic mapping
