Reversible Data Hiding Methods Based on Audio and Video Synchronization

Abstract

Steganography is the technique for concealing any mystery data like secret key, content, and picture, sound
behind unique spread record. In this paper we proposed the sound feature crypto-steganography which is the blend of
picture steganography and sound steganography utilizing PC crime scene investigation method as an instrument for
confirmation. Our point is to shroud mystery data behind picture and sound of feature document. As feature is the use of
numerous still edges of pictures and sound, we can choose any casing of feature and sound for concealing our mystery
information. Suitable calculation, for example, 4LSB is utilized for picture steganography and stage coding calculation
for sound steganography. Suitable parameter of security and verification like PSNR, histogram is acquired at collector
and transmitter side which are precisely indistinguishable, and subsequently information security can be expanded. This
paper center the thought of PC criminology method and its utilization of feature steganography in both investigative and
security way.
