An RGB colour image steganography scheme using overlapping block-based pixel-value differencing

This paper presents a steganographic scheme based on the RGB colour cover image. The secret message bits are embedded into each colour pixel sequentially by the pixel-value differencing (PVD) technique. PVD basically works on two consecutive non-overlapping components; as a result, the straightforward conventional PVD technique is not applicable to embed the secret message bits into a colour pi...

Steganalysis Method Defeating the Modified Pixel-value Differencing Steganography

Pixel-value differencing (PVD) steganography generates step effects or abnormal high fluctuations in PVD histogram. Since steganalysis exploits these artifacts to defeat the PVD steganography, modified PVD (MPVD) steganography preserving the PVD histogram is recently presented. This paper proposes a novel steganalysis method, in which we embed message one more time into the suspicious image to ...

Exploring LSB Substitution and Pixel-value Differencing for Block-based Adaptive Data Hiding

Khodaei and Faez proposed a new adaptive data hiding technique based on LSB substitution and pixel-value differencing. Their algorithm can embed a large amount of secret data while maintaining acceptable image quality. However, their proposed algorithm only has fixed embedding capacity. In addition, the derivation for three consecutive pixels in the boundary region is poorly manipulated using r...

Steganography Using Adaptive Pixel Value Differencing(APVD) of Gray Images Through Exclusion of Overflow/Underflow

In a gray scale image the pixel value ranges from 0 to 255. But when we use pixel-value differencing (pvd) method as image steganographic scheme, the pixel values in the stego-image may exceed gray scale range. An adaptive steganography based on modified pixel-value differencing through management of pixel values within the range of gray scale has been proposed in this paper. PVD method is used...

Colour Image Steganography Based on Pixel Value Differencing in Spatial Domain

In a color image every pixel value composed of red, green and blue component and each of which ranges from 0 to 255 in case of 8-bit representation. In this paper, we have used pixel value differencing (PVD) method for secret data embedding in each of the component of a pixel in a color image. But when we use pixel-value differencing (PVD) method as image steganographic scheme, the pixel values...
