A comparative study of combination with different LSB techniques in MP3 steganography

Abstract

Steganography hides the existence of the data inside any cover file. There are different file formats used in steganography like text, image, audio and video. Out of these file formats audio steganography is followed in this paper.One of the major objective of hiding data using audio steganography is to hide the data in an audio file, so that the changes in the intensity of the bits of host must not be detect by human auditory system. The focus of this paper is on time domain technique i.e. LSB technique of audio steganography. Method used in the paper hides the data in combination of LSBs instead of hiding the data in least significant bit. Results are compared by using parameters PSNR, BER and correlation.
