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 …

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

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 …

Embedding a secret message into the pixels of a cover image yields a visual distortion if
these pixels belong to smooth regions. Thus, this prompted the development of some edge …

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 …

with the rapid advance in digital network, information technology, digital libraries, and
particularly World Wide Web services, many kinds of information could be retrieved any time …

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 …

To provide higher embedding capacity without sacrificing the imperceptibility, a novel
steganographic technique based on nine-pixel differencing with modified Least Significant …

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 …

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) …
