In this paper we consider a hypothesis testing approach for detection of hiding in the least significant bit (LSB). This steganalysis problem is a composite hypothesis testing problem. We state a regularity condition on the image histogram, which reduces this problem to a simple hypothesis testing problem. We then develop a number of simple practical tests based on the estimation of the optimal...

This paper presents a technique of staganography where hiding of secret image done by LSB substitution and N-Queen matrix act as key. Key used to indicate pixel position of Cover image where substitution will take place.Memomy complex (Memory strand and DNA stickers) used to represent N-Queen matrix so that key isn’t understandable to unauthorized user. Size of NQueen matrix relate with no. of ...

In this paper, a novel data hiding technique is proposed, as an improvement over the Fibonacci LSB data-hiding technique proposed by Battisti et al. [1] based on decomposition of a number (pixel-value) in sum of natural numbers. This particular representation again generates a different set of (virtual) bit-planes altogether, suitable for embedding purposes. We get more bitplanes than that we g...

The eventual goal of steganalytic forensic is to extract the hidden messages embedded in steganographic images. A promising technique that addresses this problem partially is steganographic payload location, an approach to reveal the message bits, but not their logical order. It works by finding modified pixels, or residuals, as an artifact of the embedding process. This technique is successful...

Since the rise of the Internet, security of information is one of the most important factors of information technology. This paper represents a new approach for data hiding by combining art image creation and tree based parity check method. First, a cubism-like art image which is an abstraction by prominent lines and regions is generated using source image. Then text message is embedded using t...

Quantitative steganalysis aims to estimate the amount of payload in a stego object, and such estimators seem to arise naturally in steganalysis of Least Significant Bit (LSB) replacement in digital images. However, as with all steganalysis, the estimators are subject to errors, and their magnitude seems heavily dependent on properties of the cover. In very recent work we have given the first de...

Non-restoring division involves shifting and add/subtract operations. This paper proposes method to reduce the number of bits in shift operation during non restoring operations. The upper half of the dividend is shifted instead of whole dividend. The least significant bit of the shifted number is set to the value in lower half of the dividend depending on the iteration. The design is synthesize...
