A Novel Technique of Steganalysis in Uncompressed Image through Zipf’s Law
نویسندگان
چکیده
In this paper, we present a Novel method to detect the existence of hidden message in LSB steganography. The key element of the proposed method is the power Law: Zipf’s law.The detection theory is based on statistical analysis of pixel patterns using a Zipfness measure between successive bit planes. The basic idea is that, the correlation between bit planes as well as the binary texture characteristics within the bit planes will differ between a stego image and a cover image. The seventh and eighth bit planes, and possibly others, are used to calculate the Zipf Quality (ZQ) measure. The proposed technique does not need a reference image and it works with spatial transform-domain embedding. The method is similar to steganalysis in [12]; it exploits Binary Similarity measures of images to reveal the presence of steganographic content.

Reconstructive Steganalysis by Source Bytes Lead Digit Distribution Examination
This paper presents a novel method of JPEG image steganalysis. Our approach is driven by the need for a quick and accurate identification of stego-carriers from a collection of files of different formats, where there is no knowledge of the steganography algorithm used, nor previous database of suspect carrier files created. The suspicious image is analysed in order to identify the encoding algo...
متن کاملSteganalysis in Overlapping Images
Steganalysis aims to detect the presence of hidden information, known as steganography, in digital images. Modern detectors rely on machine learning techniques, using features from digital images to classify them as covers or stegos. Often the ability to detect steganography can be improved through a process called calibration. Calibration attempts to establish a reference for cover features in...

In this paper a steganalysis method is proposed for pixel value differencing method. This steganographic method, which has been immune against conventional attacks, performs the embedding in the difference of the values of pixel pairs. Therefore, the histogram of the differences of an embedded image is di_erent as compared with a cover image. A number of characteristics are identified in the di...
متن کاملEigenvalues-based LSB steganalysis
So far, various components of image characteristics have been used for steganalysis, including the histogram characteristic function, adjacent colors distribution, and sample pair analysis. However, some certain steganography methods have been proposed that can thwart some analysis approaches through managing the embedding patterns. In this regard, the present paper is intended to introduce a n...
متن کاملAn extended feature set for blind image steganalysis in contourlet domain
The aim of image steganalysis is to detect the presence of hidden messages in stego images. We propose a blind image steganalysis method in Contourlet domain and then show that the embedding process changes statistics of Contourlet coefficients. The suspicious image is transformed into Contourlet space, and then the statistics of Contourlet subbands coefficients are extracted as features. We us...
