摘要 LSB matching是一种广泛使用的数字图像隐写方法,但关于其隐写分析的工作目前还不多。详细讨论了最近提出的一种基于图像直方图局部极值点的关于LSB matching的隐写分析方法,指出了该方法的不足,并结合图像采样技术给出了一种新的用于LSB matching的检测子。实验表明,提出的检测子实现简单并且具有更好的检测效率。 LSB matching is a widely-used steganographie scheme for digital images.However,the study on steganalysis of LSB matching is just in the early stage.This paper discusses a recently proposed steganalysis method for LSB matching,which is based on the local extrema of image＇s histogram.Point out the defects of the above scheme, and propose a new one for detecting LSB matching by using the calibration method.Extensive experimental results show that the new discriminator is easy to implement and perform much better than the old one.
