A binary image steganalysis scheme based on the statistic model of local residual pattern (LRP) is proposed in this paper. LRP means the pattern of a local area of the residual map of the binary image, which is calculated with the XOR operation. The XOR operation is sensitive to the difference between adjacent pixels, which leads to the emphasis on edge property of the residual map. The neighbouring LRPs of the modified pixel will be affect, which makes the statistic model of LRPs change. Thus the trace of steganography can be detected according to the difference between the statistic models. Finally, the experiments we conducted show that our proposed scheme is effective on binary image steganalysis.

In recent years, reversible data hiding in binary images has become more and more important in the field of data hiding. For the binary property, hiding information in binary images can only be achieved by flipping pixels. But flipping the pixels randomly in a binary image will cause remarkable distortion. The existing methods are capable of reversible data hiding in binary images but the visual quality is not good. In this paper, we propose a novel reversible data hiding method based on symmetrical flipping degree (SFD) histogram modification. First, we define the SFD of the block, which is a visual score measured the distance between the pixels in the block. The smaller SFD is, the better the visual quality the image has. Then the histogram is generated from the SFD, and it utilizes the zero or the minimum point and modifies the pixels with high SFD for its pre-processing. Finally, the appropriate corresponding pixels are selected adaptively to flip for information embedding. Experimental results demonstrate the feasibility of our proposed method and the visual quality is satisfactory.
