一种基于文字下划线特征变化的完全脆弱型文本水印

A Fragile Text Watermarking based on Changing the Underlining Feature of Character

根据特征编码的思想,提出了一种基于文字下划线特征变化的完全脆弱型文本水印算法.使用特定的数列对文档字符进行分组,提取每组字符的Unicode码生成水印信息,然后按照一定的顺序插入水印或读取水印进行比较.

Based on feature coding idea, this paper puts forward a new algorithm of fragile text watermarking based on changing the underlining feature of character. The algorithm divides the character into many groups. The quantity of the group is decided by specific sequence, and abstracts the characters＇ Unicode of each group to obtain the watermarking information, then, according to a special order, embeds the watermarking or takes the watermarking to detect.
