The fundamental objectives of image steganographic algorithm are to simultaneously
achieve high payload, good visual imperceptibility, and security. This paper proposes a new …

The goal of image steganographic methods considers three main key issues: high
embedding capacity, good visual symmetry/quality, and security. In this paper, a hybrid data …

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) …

Image steganography is a technique for hiding the secret data in a carrier image. This paper
proposes a novel n-right most bit replacement image steganography technique to hide the …

This paper proposes an image steganography approach based on pixel value differencing
and modulus function (PVDMF) to improve the peak signal-to-noise ratio (PSNR) and hiding …

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 …

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 …

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) …

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 …

Steganography is the only answer for secure and secret communication. Existing methods in
image steganography focus on increasing embedding capacity of secret data. According to …
