Stego Machine Video Steganography using Modified LSB Algorithm
[attachment=129]
I. INTRODUCTION
STEGANOGRAPHY is an ancient art of conveying
messages in a secret way that only the receiver knows the
existence of message. The subject of steganography has been
brought into the limelight by several intelligence agencies and
the news media in recent times. Apart from using state of the
art, communication technologies and media, the agencies are
using cryptography as well as steganography to aid themselves
with their objectives [1]. So, a fundamental requirement for a
steganographic method is imperceptibility; this means that the
embedded messages should not be discernible to the human
eye.
PROPOSED SYSTEM
The existing systems lack good user interface, nonprovision
of choosing the key and more encode-decode time
consumption. There are lots of steganographic programs
available. A few of them are excellent in every respect;
unfortunately, most of them lack usable interfaces, or contain
too many bugs, or unavailability of a program for other
operating systems. The proposed application will take into
account these shortcomings, and since it will be written in
Java, operability over multiple operating systems and even
over different hardware platforms would not be an issue.
MODULES OF STEGO MACHINE
The video stegomachine performs the process of conceal
and reveal in following modules. The modules of Video
Stegomachine are
Video Header Information
File Handling
Encryption
Steganography Conceal data
DeSteganography - Reveal original data
Decryption
Graphical User Interface
Graphical User Interface (GUI)
This GUI is created as a user friendly wizard and does not
need any previous training to operate it. It helps user to do
steganography without encryption and encryption without
steganography. This will help user with a wizard to
Hide a message in a video file
Retrieve the hidden message in a stego d video
Encrypt a text file
Decrypt an encrypted file
CONCLUSION
The proposed system based on the research findings
developed an application which would be able to hide data
into video images (AVI) that provides a robust and secure way
of data transmission. This Stego system implements
steganography in video image and reveal process without
restarting the application or starting a different application.
Also this system is a Platform-independent application with
high portability and high Consistency.
