Implementation of Cryptographic Method for Secure Audio Data Hiding in Digital Image

Information security is a major obstacle in different areas like military, network application, are illegally access the information. So, it is very important to hide the secret data efficiently. By means of steganography we can hide information to be transmitted over network. In this project we have developed the technique to hide the secret short audio file into cover image to form a stego cover image in order to provide the robust security. The proposed system consists of the steganography using the wavelet based LSB technique and the cryptography which uses the BRA algorithm it takes the smallest amount of time and provides the more security. The performance analysis has been done by using the performance parameters like PSNR, MSE, SNR by using the matlab software.
