Data Security Using Steganography

Security System UsingSteganography

Introduction

While transferring a file from one point to another through Intranet and Internet we need more file secure concepts.

Ordinary, file Encryption-Decryption Concepts, which are readily available in java examples are easily captured by middle way itself.

This project helps to send a file from one place to another in a secured manner

Objective

The main objective of this project is SECURITY during file transmission

from one end to another end both in Internet and private network. The main

concept of Steganography, i.e. Encrypt a file and hide it in another media to

invisible it, is maintained by our project such that our target file will be

encrypted and embedded into an audio or video file then the resultant video

file is send through the network. The front-end screen of this software will be

designed in Java using Swing Concepts.

Steganography is the practice of hiding private or sensitive information within something that appears to be nothing out of the usual.

Steganography is often confused with cryptography because the two are similar in the way that they both are used to protect important information.

Steganography comes from the Greek words Steganós (Covered) and Graptos (Writing).

Steganography

The art of detecting Steganography is referred to as Steganalysis.

Steganalysis does not deal with trying to decrypt the hidden information inside of a file, just discovering it.

To put it simply Steganalysis involves detecting the use of Steganography inside of a file.

The most common use of Steganography is to hide a file inside another file.

There are many methods that can be used to detect Steganography.

Existing System

For Transmitting a file from one point to another many of us are using Encryption only.

This will not give that much of security.

While using Steganography for embedding a source file to an another media they are

using watermark embedding. It is also have its own disadvantages. The resultant file of

this techniques will be change from the source file. Watermark embedding is easily

decrypted by the hackers.

Encryption and Embedding only is not give that much of security to our communication.

Proposed System

In our system we are not following the regular encryption, decryption techniques.

We are Introducing a new algorithm Bit-Shift in Random Cycle Order. I.e. totally 4

different types of Bit-Shift algorithms are used randomly to encrypt the data

This Encryption is embedded into an Audio or Video File.

Again It will be embedded into another media. This double embedding increases the level

of security.

Password Protection of this entire works give an additional security.  

Technologies overview

This project helps to send a file from one place to another in a secured manner.

Firstly the target file is encrypted using an algorithm called Bit Shifting.

The Encrypted file is embedded into an audio file.

The resultant file will be embedded into a video file.

The video file and the whole thing is protected by a password and sent through net.

Modules

Connection manager Module Merger Module Extractor Module Result window Module

Merger Module

This Module is front end module and it is designed using

swing. This module gets the inputs from sender. The inputs are

Audio/ video, Image/Text and secret message file with password.

Then merge the all requirements and then send to receiver.

Connection manager Module

The merged file can send from sender or

server to receiver. The UDP protocol can be use

for that networking process.

Extractor Module

This module gets the merged file after a

password verification. Then extract the merged

file and call the result window module to open

extracted file.

Result window Module

This module displays the original secret file

and covered Audio/Video file .
