一种基于文本行和对角侧面特性的数字水印方法

针对文本文件的特点，提出一种基于文本的行和对角侧面特性水印方法．该方法利用文本具有行的特征嵌入水印信息，大大增加水印容量，提取水印只需要行对角侧面，可以不用原始文本参照，同时该方法还可以用文本对角侧面特性来检测文本的完整性．实验表明，这种方法对于典型的剪切和噪声干扰具有一定鲁棒性．

Watermarking Method Using Line and Diagonal Profile for Text Documents

A watermarking method for text documents was presented using line and diagonal profile. The watermark is embedded into text documents based on its characteristic, and watermark bits embedded can be very large. The watermark is extracted using line diagonal profile without resorting to original unmarked text document. In addition, the text diagonal profile can be used to detect the integrality of text document. Experimental results show that this method is robust with a certain extent to the typical image processing attacks such as cut and noise addition.
