Steganalytic Measures for the Steganography Using Pixel-Value Differencing and Modulus Function

The steganalytic measures are proposed to destroy the steganographic method using pixel-value differencing(PVD) and modulus function. The modulus PVD steganography method utilizes the remainder of the two consecutive pixels to embed the secret data, which gains more flexibility and is capable of deriving the optimal remainder of the two pixels at the least distortion. However, there exist unavoidable weaknesses: fluctuation of the histogram, asymmetry of the 1 and -1 histogram values, and abnormal increasing of the 0 histogram value. The steganalytic measures are designed using these weaknesses of the modulus PVD steganography method. Through experiments, we prove that the proposed steganalytic measures successfully defeat the modulus PVD steganography method.
