  Steganography is the art of hiding data, in such a way that it is
undetectable under traffic-pattern analysis and the data hidden is only known
to the receiver and the sender. In this paper new method of text steganography
over the silence interval of audio in a video file, is presented. In the
proposed method first the audio signal is extracted from the video. After doing
audio enhancement, the data on the audio signal is steganographed using new
technique and then audio signal is rewritten in video file again.

  To enhance the security level we apply chaotic maps on arbitrary text.
Furthermore, the algorithm in this paper, gives a technique which states that
undetectable stegotext and cover-text has same probability distribution and no
statistical test can detect the presence of the hidden message.

  Moreover, hidden message does not affect the transmission rate of video file
at all.
