Analysis of secured video steganography using computer forensics technique for enhance data security

Steganography is used to hide the messages inside other harmless messages in a way that does not allow any enemy to even sense that there is a second secret message present while the purpose of computer forensics is that it provides security from covert communication dealing with digital data and covert communication channel. In this paper we used video as cover media for hiding the secret message and used computer forensics as tool for authentication. Our aim is to hide an image and text behind a video file. Suitable algorithm such as 1LSB, 2LSB, 4LSB is used and 4LSB method found to be good for hiding more secret information data. This paper deals with the idea of video steganography, cryptography and the use of computer forensic techniques in both investigative and security manner.
