A NEW STEGANOGRAPHY DATA HIDING ALGORITHM

Abstract

Steganography is the art or practice of concealing a message, image, or file within another message, image, or file. It serves as a better method of securing message than cryptography which only conceals the content of the message not the existence of the message. This means that, the original message is being hidden within a carrier such that the changes so occurred in the carrier are not observable. In this paper, we proposed a new steganography scheme for hiding a piece of critical information in a host binary image. The proposed scheme presents a new form of weight matrix and a secret key. The weight matrix is dynamic that is it changes its position at every block of the image to increase the security. The performance of the proposed scheme is compared with that of the Chen et al scheme (CPT scheme). The results show that our scheme provides a higher security, and hides a higher amount of data than CPT scheme, and it keeps that same quality level of the host image as the CPT scheme.
