鲁棒可逆文本水印算法

针对法律或军事领域在使用文本文件时必须要求真实性的要求,提出一种鲁棒可逆文本水印算法.根据0/1水印序列和同义词替换评价模型,将水印有选择地嵌入到原始文本中.投票原则的使用提高了水印的鲁棒性并降低了误检率,拥有密钥和其他秘密参数的用户才可以完全恢复原始数据.理论分析和仿真结果表明,采用文中算法嵌入的水印具有较好的不可见性和较强的鲁棒性.

Robust Reversible Text Watermarking Algorithm

Targetted at demands in law or military fields where digital media do not allow any losses,we present a robust reversible text watermarking scheme.According to 0/1 watermarking sequence and the synonymy substitution evaluation model,the watermark is selectively embedded in the original text.The majority voting rule improves the watermarking robustness and reduces the probability of false positives.The original data can be recovered losslessly from the unmodified watermarked text by users who own the private...
