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。In this paper it puts forward a new algorithm of fragile text watermarking based on the feature change of the characters＇ underlining 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 demonstrate that the algorithm is good at the imperceptibility and is sensitive to various watermark attacks, and can position the tamper accurately in most eases as well.
