Digital steganography has a long history, starting to be developed in the 90s until now. The
main aspects of early steganography are security, imperceptibility, and payload. Security is …

Peak signal to noise ratio (PSNR) and structural index similarity (SSIM) are two measuring
tools that are widely used in image quality assessment. Especially in the steganography …

Various image steganography methods have been developed to improve the stego image
quality, ie imperceptibility, capacity, and security. This research proposes an adaptive …

With the development of Internet and multimedia development, digital image steganography
is becoming more extensive in transmitting data with high capacity and security. Although …

The aim of designing self-embedding fragile watermarking is copy-right protection, tamper
localization and image recovery. This paper proposes a self-embedding fragile …

This paper introduces an edge-based image Steganography scheme in which the pixels of
the cover images are categorized into two classes: edge and non-edge. In general, the edge …

Today's information technology tools allow people to share personal data and information
through online media. Data security techniques are also developed to protect confidential …

Conventional steganography methods fabricate the secret information into the cover pixels
without analyzing the pixel intensities of an image. As a result, some minor pixel level …

Steganography surpasses other mechanisms of securing data from potential threats. The
modern digital arena calls for robust information hiding techniques and, thus, it has always …

In digital image processing and steganography, images are often described using edges
and local binary pattern (LBP) codes. By combining these two properties, a novel hybrid …
