Many existing steganographic methods hide more secret data into edged areas than smooth
areas in the host image, which does not differentiate textures from edges and causes …

Data hiding called steganography is a security technique to protect secret data throughout
the transmission from malicious attackers. The purposes of steganography are to obtain …

In order to improve the capacity of the hidden secret data and to provide an imperceptible
stego-image quality, a novel steganographic method based on least-significant-bit (LSB) …

The proposed scheme groups three pixels as an embedding unit to conceal three bits of
secret data in which the possible modification for each pixel is at most+ 1 or− 1. With our …

This paper proposes a new adaptive least-significant-bit (LSB) steganographic method
using pixel-value differencing (PVD) that provides a larger embedding capacity and …

Steganography is the art and practice of communication using hidden messages. The least
significant bits (LSB) based method is the well-known type of steganography in the spatial …

To enhance the embedding capacity of image steganography and provide an imperceptible
stego-image for human vision, a novel adaptive number of least significant bits substitution …

This study presents a new adaptive data-hiding method based on least-significant-bit (LSB)
substitution and pixel-value differencing (PVD) for grey-scale images. The proposed method …

Several problems arise among the existing LSB-based image steganographic schemes due
to distortion in a stegoimage and limited payload capacity. Thus, a proposed scheme has …
