摘要

提出了一种用于二值文本图像的数字水印算法。该方法首先对文本图像进行字符切分

然后在乘性变换模型的假设之下

通过翻转字符图像的边界像素点来实现水印嵌入。同时

提出了一种完善的边界点翻转策略

使得嵌入水印的图像很难发现被修改的痕迹。实验表明

该算法可以有效抵抗打印和复印攻击

从而达到对于纸质文本文件的信息隐藏的目的

可以用于纸质文本文件的消息源头追踪。

Abstract

A digital watermarking scheme for binary document image was proposed.First

a binary document image was segmented into individual characters.Then

based on the multiplicative transformation model

watermark was embedded by flipping the boundary points of each character.Moreover

a strategy is proposed for flipping the boundary points to ameliorate the visual imperceptibility of the watermarked image.Extensive experimental results show that the proposed scheme is effective to resist print-and-copy

it can achieve the purpose of hiding information in paper documents and can be used for information tracking.
