The document describes a security system utilizing steganography for secure file transmission over networks by embedding encrypted files within audio or video files. It proposes a novel algorithm called bit-shift for encryption and aims to enhance security with double embedding and password protection. The system's architecture comprises various modules for file merging, transmission, extraction, and displaying results, ensuring greater security than traditional encryption methods.

1. Security System Using
Steganography

2. 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

3. 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.

4. 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

5.  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.

6. 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.

7. 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.

8. 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.

9. Modules
 Connection manager Module
 Merger Module
 Extractor Module
 Result window Module

10. 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.

11. Connection manager Module
The merged file can send from sender or
server to receiver. The UDP protocol can be use
for that networking process.

12. 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.

13. Result window Module
This module displays the original secret file
and covered Audio/Video file .
