A Multilayered Secure Scheme for Transmission of Sensitive Information based on Steganalysis

We propose a multilayered secure scheme to transfer sensitive text over an unreliable network. The secret text is first encrypted using the AES algorithm. The cipher text produced is hidden in an audio file. The audio file is in turn encrypted in parallel using the concept of Shamir's technique based on CRT to maximize resource utilization. These, audio shares are sent over different channels in the network for security. Experimental results show that, even if certain shares got lost over network, audio files could be recovered at the receiver with the remaining shares without sender needing to resend the file.
