Colour image steganography through channel transformation approach

Colour Guided Colour Image Steganography

Information security has become a cause of concern because of the electronic eavesdropping. Capacity, robustness and invisibility are important parameters in information hiding and are quite difficult to achieve in a single algorithm. This paper proposes a novel steganography technique for digital color image which achieves the purported targets. The professed methodology employs a complete ran...

Mosaic Image Steganography Based Colour Transformation for Enhanced Security

A new secure image transmission method is proposed, Here it uses the technique of Steganography and Cryptography, Which transforms automatically a given large-volume secret image into a so-called secret-fragment-visible mosaic image of the same size. The mosaic image which looks similar to an arbitrarily selected target image and may be used as a disguise of the secret image is yielded by divid...

A Novel Approach to RGB Channel Based Image Steganography Technique

Steganography in image using discrete wavelet transformation

In this paper, we propose a new algorithm of steganography to allow simultaneous hiding secret message and small-size image into an large-size image. To hide the secret message in small image we use the Least Significant Bit (LSB) substitution, and the method for hiding the image in the image cover use Discrete Wavelet Transformation (DWT). The proposed method results in increasing the secret m...

Object-Based Image Steganography Using Affine Transformation

The typical model of steganography has led the prisoners’ problem, in which two persons attempt to communicate covertly without alerting the warden. The general way to achieve this task is to embed the message in an innocuous-looking medium. In this paper, an object-based geometric embedding technique is proposed for solving the prisoners’ problem. The main idea is to embed secret data through ...
