This document describes an ATM security system that uses steganography to securely transmit files. The system encrypts files using a random bit-shift encryption algorithm and embeds them into audio or video files for transmission. At the receiving end, the encrypted file is extracted from the carrier file after entering the correct password. The system aims to provide stronger security than regular encryption by hiding encrypted files within innocent-looking media during transmission.

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 VideoFile.
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.
9. 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.
10. Connection manager Module
The merged file can send from sender or
server to receiver. The UDP protocol can be use
for that networking process.
11. 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.
