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 …

To protect from pixel difference histogram (PDH) analysis and RS analysis, two hybrid image
steganography techniques by appropriate combination of LSB substitution, pixel value …

In the recent past some steganography techniques by combining least significant bit (LSB)
substitution and pixel value differencing (PVD) have been proposed to improve upon the …

The least significant bit (LSB) substitution techniques are detected by RS analysis and the
traditional pixel value differencing (PVD) approaches are detected by pixel difference …

This paper proposes an image steganography technique based on the principle of pixel
overlapping to improve the embedding capacity (EC) and peak signal-to-noise ratio (PSNR) …

This paper proposes two pixel value differencing (PVD) steganography techniques by
considering adaptive ranges to improve the security. In the first technique, the image is …

Pixel value differencing (PVD) and least significant bit substitution (LSB) are two widely used
schemes in image steganography. These two methods do not consider different content in a …

Since the inception of pixel value differencing (PVD) image steganography, it has drawn
considerable interest among the researchers of this field. However, most of the PVD based …

Pixel value differencing steganography (PVDS) technique efficiently identifies the edge and
smooth regions from an image, therefore, the PVDS technique is more suitable for …
