A Novel DWT & Correlation Based Audio Steganography

Abstract

This paper presents a method of hiding the text message into audio. Data hiding, a form of steganography, is one of the emerging techniques that embeds secret data into a digital media and thus ensures secured data transfer. In this paper, the steganographic method used, is based on audio steganography which is concerned with embedding secret data in an audio file. The proposed method offers high quality of steganography process in terms of Peak Signal–to-Noise Ratio (PSNR).The technique is implemented in matlab since it is a language for data analysis and numerical computation. This proposed scheme includes dynamic coding approach for hiding the secret text. In this scheme no audible distortion after message insertion in audio signal.
