Executive Summary

Steganography provides security and privacy of information on open environment systems. Audio steganography plays a vital role in hiding information by exploiting the human ear perceptibility. In this paper, the harmonic component that is imperceptible to the human auditory system is manipulated using Fast Fourier Transform to hide data within the samples. The decoder samples the modified song and extracts the hidden message with the key, using an error correcting code to fix any bits altered by the channel.
