| 摘 要： | 根据特征编码的思想,首次提出了一种基于文字下划线特征变化的脆弱型文本水印算法.该算法利用字符的内码特征信息生成水印,然后按照特定的顺序插入水印或检测水印.理论分析和实验表明,算法具有良好的不可感知性,能准确地检测各类水印攻击,在大部分情况下能对篡改进行精确定位.

| Abstract: | In this paper it puts forward a new algorithm of fragile text watermarking based on the feature change of the characters' underlin- ing by applying the thoughts of feature coding.The algorithm abstracts characters' Unicode code to generate the watermarking information, then in accordance with a specific sequence embeds or detects the watermarking.The theoretical analysis and the experimental results demon- strate that the algorithm is good at the imperceptibility and is sensitive to various watermark attack... |
