Steganography between Silence Intervals of Audio in Video Content Using Chaotic Maps

摘要

Steganography is the art of hiding data, in such a way that it isundetectable under traffic-pattern analysis and the data hidden is only knownto the receiver and the sender. In this paper new method of text steganographyover the silence interval of audio in a video file, is presented. In theproposed method first the audio signal is extracted from the video. After doingaudio enhancement, the data on the audio signal is steganographed using newtechnique and then audio signal is rewritten in video file again.http://www.learnrnd.com/All_latest_research_findings.php To enhance the security level we apply chaotic maps on arbitrary text.Furthermore, the algorithm in this paper, gives a technique which states thatundetectable stegotext and cover-text has same probability distribution and nostatistical test can detect the presence of the hidden message.http://www.learnrnd.com/detail.php?id=Biohack_Eyes_through_Chlorin_e6_eye_drop_:Stanford_University_Research Moreover, hidden message does not affect the transmission rate of video fileat all.
