THE AUDIO STEGANALYSIS SYSTEM BASED ON MUTUAL INFORMATION APPROACH

Abstract

Steganography is a technique whereby we put the existence of a message to question by simply covering it up within another file image or video. This system used the input audio signals as hidden message with audio signal which is embedded based on the stenographic tool and pure audio signal. The proposed system tested the steganalysis technique on audio signals embedded with Invisible Secret tools which are available from the Internet. The aim of the system is to develop the steganography detection system using the concept of data analysis approach. To evaluate the performance of proposed system, three types of audio signal are analyzed with different number of bit stream. Overall detection accuracy for various types of music is around 90% and experiments showed that the proposed passive steganalysis is to detect hidden message in audio files.
