Statistical feature-based steganalysis for pixel-value differencing steganography

Abstract

Pixel-value differencing (PVD) steganography is a popular spatial domain technology. Several PVD-based studies have proposed extended PVD steganography methods. The majority of these studies have verified their security against the regular-singular (RS) analysis. However, RS analysis is aimed at the feature of the least significant bit substitution method, which is relatively less significant for PVD steganography. The pixel difference histogram (PDH) is generally utilized to attack PVD steganography. If the embedding capacity is high, then the features on the PDH are evident; otherwise, the features are less obvious. In this paper, we propose a statistical feature-based steganalysis technique for the original PVD steganography. Experimental results demonstrate that, compared with existing steganalysis technique with weighted stego-image (WS) method, the proposed method effectively detects PVD steganography at low embedding ratios, such that there is no need of using the original embedding parameters. Furthermore, the accuracy and precision of the method are better than those of existing PVD steganalysis techniques. Therefore, the proposed method contributes to the security analysis of the original PVD steganography as an alternative to the commonly used RS, PDH and WS attack techniques.

An Improved Steganographic Scheme Using the Contour Principle to Ensure the Privacy of Medical Data on Digital Images

“…The researchers Patel et al [14] presented a full review of the inquiry of video steganography in the uncompressed and compressed domains, in which several compressed and uncompressed mediums with their advantages and disadvantages in terms of information concealing were presented. The authors Lin et al [15] demonstrated feature-based steganalysis for Pixel-Value Differencing Steganography, and the model demonstrates the significance of statistical features-oriented embodiment and detection techniques. Authors Kordov et al [16] have proposed another implementation of the steganography principle based on color photos medium images with random order pixel selection and encrypted text message embedding.…”
