Enhancement of Information Hiding in Audio Signals with Efficient Lsb Based Methods

In the modern era the easiness in the content alteration and copying in an available digital domain have enriched the security of academic copyrights as well as the anticipation of the illegal inference of data of multimedia have turned into a significant research and technological issue. Steganography is called as an art of secret and secured communication. The basic idea behind this paper is to find the best way to embed text data in audio file using the steganography techniques. Our proposed method uses LSB technique only in specific bit positions which are known only to sender and receiver. Our results have shown that the quality of the audio remains same after embedding the secret text and also very less difference between the original audio and steganographed audio. These results were obtained by the estimation of PSNR, MSE and audio features such as Pitch, Entropy and Flatness etc. The size of the audio signal also remains unaltered.
