摘要
提出了一种针对二值图像信息隐藏的攻击方法。该方法利用图像滤波理论,对携带信息的载体图像滤波来预测原始载体图像,通过计算游程统计规律来检测基于修改游程的信息嵌入。该算法不但可以可靠地判定载体图像是否含有隐藏信息,而且还能较为准确地估计出嵌入容量。
Many steganalytic techniques of color images were presented in recent years,but only a few of them can be directly applied in binary images. This paper presents a novel steganalytic scheme that can reliably detect messages hidden in binary image using run_length modification method. The key element of this scheme is estimation of the original image, which is done by filtering the stego_image with low pass filter. This method is able to detect embedding rates.
