This paper presents a novel steganographic method based on Least Significant Bit (LSB)
substitution and 8-neighboring Pixel Value Differencing (8nPVD) for gray scale image in …

Least significant bit (LSB) is a commonly used spatial domain technique which is classified
into LSB replacement, LSB matching and matrix embedding. This paper models an …

Steganography is an art of hiding the existence of data that is it hides the secret message in
the digital cover medium. This paper introduces an improved algorithm that uses pixel value …

The present paper proposes a novel method for grayscale image steganography which
provides minimal distortion. The cover image is first divided into some blocks such that each …

A two layer data hiding method for RGB color image has been proposed in this paper. It is
an enhancement of Wu and Tsai's method (PVD) and JK Mandal's method (Color Image …
