Semi Random Position Based Steganography for Resisting Statistical Steganalysis
نویسندگان
چکیده
Steganography is the branch of information hiding for secret communication. The simplest and widely used steganography is the LSB based approach due to its visual quality with high embedding capacity. However, LSB based steganography techniques are not secure against statistical steganalysis mainly χ2 attack and Regular Singular (RS) attack. These two staganalysis can easily estimate the hidden message length. This work propose a LSB based steganography technique where first a location is obtained randomly based on the bit pattern (except LSB) of a cover pixel using linear probing and embed a secret bit into LSB. This technique makes the stego-image completely secure against both χ2 attack and RS attack.

Comparison of Two Kinds of Image Scrambling Methods Based on LSB Steganalysis
According to the research of LSB steganalysis, LSB steganography could destroy the distribution of 0 and 1 in the lowest bit planes, and this situation will cause the abnormality of histogram and asymmetry statistical, thereby left an opportunity that could be exploited to the steganalysis. From the view of steganalysis, this paper compared the two typical kinds of image scrambling methods whic...
متن کاملDetection of perturbed quantization (PQ) steganography based on empirical matrix
Perturbed Quantization (PQ) steganography scheme is almost undetectable with the current steganalysis methods. We present a new steganalysis method for detection of this data hiding algorithm. We show that the PQ method distorts the dependencies of DCT coefficient values; especially changes much lower than significant bit planes. For steganalysis of PQ, we propose features extraction from the e...
متن کاملMulti Bit Plane Image Steganography
This paper addresses a novel steganography method for images. Most statistical steganalysis algorithms are strong to defeat previous steganography algorithms. RS steganalysis and pixel difference histogram analysis are two well-known statistical steganalysis algorithms which detect non-random changes caused by embedding a secret message into cover image. In this paper, we first explain how two ...

Recently, the JPEG images are the most common format for storing images. JPEG images are very abundant on the Internet bulletin boards and public Internet sites. So it attracted the attention of researchers as the main steganographic format. There are many new and powerful steganography and steganalysis techniques in JPEG images reported in the literature, in the last few years. In this paper, ...
متن کاملAn Adaptive Steganographic Method Using Additive Noise
This paper proposed an adaptive multi-ary steganographic method based on additive noise to ensure the security of secret information. In order to minimizing the distortion caused by embedding operations, the characteristics of multi-ary steganography by adding removable noise and multi-ary matrix embedding are analyzed, and then a combination-based coding method is proposed for embedding inform...
