一种适合二值图像的安全信息隐藏算法

提出了一种二值图像信息隐藏的水印嵌入算法，他适合包括传真、印章、文本、图表等在内的所有二值图像，具有一定的自适应性，针对具有不同内容的二值图像，根据所计算出来的距离矩阵和象素的可改变程度来选择最佳的水印嵌入位置。此方法可以通过质量因子来调整水印嵌入数量，同时利用一个安全密钥在水印嵌入的时候加密信息的隐藏。实验和分析结果表明，算法具有较高的安全性和人眼不可察觉性。

An Secure Data Hiding Arithmetic Adapting to Binary Images

A watermark embed arithmetic of data hiding for binary images is proposed.This proposed method adapts to all images including faxes,print,text,chart and so on,it having stated adaptability and can select the best watermark embed position according to calculate distance matrix and changeable degree of pels.This method can regulate the quantity of watermark embed through quality gene,while encrypt data using a secure key.Experiment and analysis show this method has more security and vision invisible.
