摘要
提出了一种隐藏二值图像的方法,它利用游程编码技术实现对二值图像的无损压缩来减少对掩护载体的像素修改。实验结果表明,相对于传统的LSB隐藏方法,本算法在一定程度上能抵抗RS检测攻击,其载密图像在视觉上更不容易被察觉,秘密信息的安全性得到了增强。
This paper puts forward a method to conceal black and white image, which applies runlength code technique to realize non-damage compression to the white and black image in order for decrease the pixel modification to the covering carrier. The experimental results show that the algorithm can resist RS check attack in some degree compared with the traditional LSB concealment method, so the image with secret is not easy to be found in vision, the security of secret information increases.
