An approach for enhancing message security in audio steganography

Concealing a message and ensuring its security is inevitable in data transmission. Among various concepts, one approach is steganography that encodes secret message in indiscernible way. In this paper, we present an audio steganographic technique and propose a novel approach to hide data in the least significant bit (LSB) of the stereo-audio samples with CD-quality. Here, on the basis of stego-key and its parity, message bits are encoded into cover audio samples. In terms of security and imperceptibility, this method is a significant improvement of LSB method for hiding information in audio.
