RGB Frequency Based Image Steganography

A Novel Approach to RGB Channel Based Image Steganography Technique

Dynamic Approach of Frequency Based Image Steganography

In this paper, we propose a dynamic approach to image steganography in the frequency domain in order to increase the hiding potential of the cover image. Concealing a secret file in another file for the sake of its safe transmission via the communication channel is the main aim of a steganography technique. Embedding small size messages in a cover image has less possibilities of hampering the q...

A Dynamic RGB Intensity Based Steganography Scheme

Steganography meaning covered writing. Steganography includes the concealment of information within computer files [1]. In other words, it is the Secret communication by hiding the existence of message. In this paper, we will refer to cover image, to indicate the images that do not yet contain a secret message, while we will refer to stego images, to indicate an image with an embedded secret me...

Location-Based Image Steganography

The objective of steganography is to conceal the presence of a secret communication. Nevertheless, with the development of steganalytic attack, also known as steganalysis, there are many statistical methods to estimate the presence and ratio of secret messages. The chi square (χ 2 ) attack and regular-singular (RS) attack are two well recognized and widely applied statistical steganalysis schem...

Edge-based image steganography

This paper proposes a novel steganography technique, where edges in the cover image have been used to embed messages. Amount of data to be embedded plays an important role on the selection of edges, i.e., the more the amount of data to be embedded, larger the use of weaker edges for embedding. Experimental results have shown that the proposed technique performs better or at least at par with th...
