Video Steganography : An Approach To Hide Text And Image Data using sequential coding

Abstract

Steganography refers to data or a file that has been hide within a digital image, video or audio file. If
someone views the article during which the data is hidden within, he or she is going to haven't any indication that there's
any hidden data that the person won't try and decode the data. Steganography is employed to cover the messages within
alternative harmless messages during a means that doesn't permit any enemy to even sense that there's a second secret
message present whereas the aim of computer forensics is that it provides security from covert communication handling
digital information and covert communication channel. In this paper we tend to used video as cover media for
concealment(hide) the secret message or images. Steganography are often divided into Text Steganography, Image
Steganography, Audio/Video Steganography. Need of concealing info from intruders has been around since ancient
times. Today Digital media is obtaining advanced like text, image, audio, video etc. In this paper, we propose a secure
video steganography algorithm using sequential encoding/decoding process. To keep up the secrecy of data, totally
different ways of concealing are evolved. One amongst them is Steganography, which suggests concealing data
underneath another data while not noticeable modification in cover data. The experimental result shows the cover video
and steganography video having no perceptual difference. In this paper, PSNR and MSE of the cover video frame and
stego video frame is compared and histogram is almost identical.
