We present a novel technique for effective steganalysis of high-color-depth digital images
that have been subjected to embedding by LSB steganographic algorithms. The detection …

Steganography is define as the process of hiding information in a multimedia carrier. Its
ultimate objectives are undetectability and robustness of the hidden data. Least significant …

This paper presents a steganographic scheme based on the RGB colour cover image. The
secret message bits are embedded into each colour pixel sequentially by the pixel-value …

This letter presents a novel image steganography method that utilizes a two-way block-
matching procedure to search for the highest similarity block for each block of the important …

Steganography is a method of secret communication wherein the very existence of
communication is hidden. During the last few decades there have been a tremendous …

This paper introduces a high capacity image hiding scheme with enhanced stego image
quality. This new hiding scheme utilizes a multiscale Laplacian pyramid of the cover image …

Given the increased popularity of the internet, the exchange of sensitive information leads to
concerns about privacy and security. Techniques such as steganography and cryptography …

Steganographic techniques accomplish covert communication by embedding secret
messages into innocuous digital images in ways that are imperceptible to the human eye …

Some steganography methods for gray‐scale image can be extended to true RGB color
image by treating each of its three color channels as a gray‐scale image. In modern popular …

Steganography has been emerged as a prominent technique for communicating secret
information in a proper multimedia career. In image steganography, least significant bit …
