Detecting LSB Steganography in Images
نویسندگان
چکیده
In this paper, we present techniques to detect Least Significant Bit (LSB) steganography for images. Here, images can be hidden inside lower bits of the pixels of the cover image. We use image statistics to detect two cases when hidden image is stored as one big chunk (Simple Mode) or spread out(Shuffle Mode). The results are presented on a synthetically generated database of around 350 steganographic images. We also analyze the detection rate of a popular steganography tool, StegDetect against a hiding tool, JPHide. Based on this analysis, we present intuitions about what types of images can act as good cover images for this tool.

Eigenvalues-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 کاملStegExpose - A Tool for Detecting LSB Steganography
Steganalysis tools play an important part in saving time and providing new angles of attack for forensic analysts. StegExpose is a solution designed for use in the real world, and is able to analyse images for LSB steganography in bulk using proven attacks in a time efficient manner. When steganalytic methods are combined intelligently, they are able generate even more accurate results. This is...

Abstract In this paper, we propose a comprehensive steganalysis scheme for JPEG images. In this method, the optimized features which can interpret high distinction between cover and stego images are extracted from images. These features have been selected after a careful study on modifications caused by different steganography algorithms on statistical characteristics of images. Furthermore, us...
متن کاملDetection of LSB Steganography via Sample Pair Analysis
This paper introduces a new, principled approach to detecting LSB steganography in digital signals such as images and audio. It is shown that the length of hidden message embedded in the least significant bits of signal samples can be estimated with relatively high precision. The new steganalytic approach is based on some statistical measures of sample pairs that are highly sensitive to LSB emb...
متن کاملSteganalysis: Detecting LSB Steganographic Techniques
Steganalysis means analysis of stego images. Like cryptanalysis, steganalysis is used to detect messages often encrypted using secret key from stego images produced by steganography techniques. Recently lots of new and improved steganography techniques are developed and proposed by researchers which require robust steganalysis techniques to detect the stego images having minimum false alarm rat...
