摘要
提出了一种基于英文单词属性的文本零水印算法。通过提取文本中各单词字符数量的奇偶性作为文本特征,并与水印信息构建出文本零水印。仿真结果证明算法具较强的隐藏性和鲁棒性,并且能有效地抵制针对文本的编辑操作。
A text zero - watermarking algorithm based on the English words property is proposed. The text features what is determined by the parity of characters in the word, is built text zero - watermarking with watermark information. Simulation resuits show a strong hidden algorithm and robustness, and can effectively resist the text for editing.
