In order to protect secret digital documents against vulnerabilities while communicating,
steganography algorithms are applied. It protects a digital file from unauthorized access by …

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 …

In this paper, we have proposed a new data hiding approach using Pixel Value Diference
(PVD) seganography for digital image. PVD steganography, proposed by Wu and Tsai, use …

Steganography is crucial for maintaining integrity, authenticity, copyright protection, illegal
use detection, and distribution of digital media over public networks. In this paper, a new …

Steganography is an important secret information communication technology in which one
may send messages without others having knowledge of their existence. This paper …

Khodaei and Faez proposed a new adaptive data hiding technique based on LSB
substitution and pixel-value differencing. Their algorithm can embed a large amount of …

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

This paper presents two adaptive and non-adaptive data hiding methods for grayscale
images based on modulus function. Our adaptive scheme is based on the concept of human …

Rapid growth in the demand and consumption of digital information in past decade has led
to valid concerns over issues such as content security, authenticity and digital right …

Data hiding is the art of hiding data for various purposes such as; to maintain private data,
