Secured image transmission with GA based Audio Steganography

Abstract

Audio Steganography is a method that ensures secured data transfer between parties normally in internet community. In this paper, we present a novel, principled approach to resolve the remained problems of substitution technique of Audio Steganography. In the first level, here we first extract image data from an image file. In the second level, we use a powerful GA (Genetic Algorithm) based LSB (Least Significant Bit) Algorithm to embed t h e image data into audio data. Here image data bits are embedded into random and higher LSB layers, resulting in increased robustness against noise addition. On the other hand, GA operators are used to reduce the distortion.
