World is now considered as global village because of interconnected networks. Smart
phones and large computing devices exchange millions of information each day. Information …

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

This article proposes a very high capacity steganography technique using differencing and
substitution mechanisms. It divides the image into non-overlapped 3 * 3 3× 3 pixel blocks …

The main challenges of image steganography are imperceptibility of the cover image and no
recoverability of the secret data. To deal with these challenges, a modified digital image …

Steganography is one of the approaches used in data hiding. Image steganography, is a
type of steganography that the image is used as a covering object. Data hiding capacity and …

This paper presents a novel approach for Image steganography based on Integer Wavelet
Transform. In this method, the cover image is mapped to a specific frequency domain. Then …

Background: Encrypting plain images into noise-like cipher images is a common method in
image encryption. However, when noise-like images appear in public networks, they are …

This paper proposes an adaptive fuzzy inference approach for color image steganography,
taking into account the influence of image complexity such as pixel similarity, pixel …

Steganography is the science of hiding secret message in an appropriate digital multimedia
in such a way that the existence of the embedded message should be invisible to anyone …

A new steganography algorithm based on five protection layers has been suggested in this
paper for embedding a large amount of secret messaging in a color image, as represented …
