In image steganography, least significant bits replacement and pixel-value differencing
methods have been used. In this paper, data hiding methods based on least significant bits …

The combination of pixel value differencing (PVD) and least significant bit (LSB) substitution
gives higher capacity and lesser distortion. However, there are three issues to be taken into …

This article proposes a very high capacity steganography technique using differencing and
substitution mechanisms. It divides the image into non-overlapped 3 * 3 3× 3 pixel blocks …

In this chapter, we propose an improved image steganography method using the concept of
least significant bit (LSB) substitution and pixel value differencing (PVD). The major …

Histogram-based steganalysis methods diagnose abnormalities in the stego histogram.
LSB+ and outguess are two steganography methods which preserve the cover histogram …

In this paper, a new histogram-based approach for digital image steganography is
introduced. It stems from the idea of utilizing the near maximum values in the image …

A novel Steganographic method based on four-pixel differencing and modified least
significant bit (LSB) substitution is used to increase the embedding capacity and to maintain …

To provide higher embedding capacity without sacrificing the imperceptibility, a novel
steganographic technique based on nine-pixel differencing with modified Least Significant …

The Least Significant Bit (LSB) substitution is an old and simple data hiding method that
could almost effortlessly be implemented in spatial or transform domain over any digital …

Several steganographic methods have been proposed based on pixel value differencing
(PVD) attempting to increase the embedding capacity without great loss in the perceived …
