Audio Steganography using Probabilistic Global Search Lausanne Algorithm

Abstract

Audio Steganography is an art of hiding secret information within multimedia objects to prevent unauthorized persons. Information hiding technique using audio sound files is a new kind of secret communication technology. Fast improvement of Internet and digital information revolution caused major changes in the overall culture. Audio data hiding method is one of the most effective ways to protect our privacy. Nowadays, embedding message within audio files is still challenging problems. In this paper, we present one of the problem transformation method, PGSL algorithm is used for secure digital audio Steganography. Message bits are embedded within the best points of audio file through PGSL to have high security as well as robustness.
