Abstract
The main objective idea of the proposed technique is that the matrix of wave audio file reshape by using Mat lab program tools in order to change sound format (matrix in one dimension) to image format (matrix in two dimension), the result audio color image become the cover or host signal in which the data can be securely hidden within its components (Red, Green, Blue).The secret message (image, sound, text) hide by using traditional method for steganography art in spatial domain called least significant-bit (LSB). the benefit of this technique in our work is to hide secret color image within audio color image, to increase security degree in this technique the cover sound converted to image and secret message converted to sound (from image 8 bit format to sound 8 bit format), the result sound has been encrypted by using secret Chaotic key generation (CKG) and then the result numbers convert to binary numbers the one dimension logistic maps are used as chaotic key generation, the first three bits of each number have been hiding inside red component of audio color image, the second three bits of each number have been hiding inside green component of audio color image and the last two bits have been hiding inside blue component of audio color image. The proposed methods offer high quality of steganography process in terms of SNR (signal to noise ratio), MSE (mean square error) and correlation measure (Correlation). Only minor changes in the contents of the audio file occur, which are undetectable to human auditory system (HAS).
