INTRODUCTION

The File Security System is a software, which tries to alter the originality of the text into some encrypted form.

It is use to store the information in a form that is unreadable.

The Application should have a reversal process as of which should be in a position to decrypt the data to its original format upon the proper request by the user.

OBJECTIVE OF FILE SECURITY SYSTEM

Secure the file from unauthorized user.

If hacker get the encrypted file they can not read to the file.

It give confidentiality to user that information is secure.

TECHNIQUE USED IN FILE SECURITY SYSTEM

Encryption

Decryption

ENCRYPTION

Encryption is the process of encoding messages (or information) in such a way that eavesdroppers or hackers cannot read it, but only authorized parties can access.

In an Encryption scheme, the message or information (referred to as plaintext) is encrypted using an encryption algorithm, turning it into an unreadable cipher text. This is usually done with the use of an encryption key.

This is usually done with the use of an encryption key which specifies how the message is to be encoded.

There are two basic types of encryption

schemes: Symmetric-key encryption

Asymmetric-key(public-key encryption)

DECRYPTION

Decryption should be a reverse process of encryption process.

Decryption is the process of encoding messages (or information) in such a way that it become readable for users.

It convert the cipher text into the plain text after encryption.

SYMMETRIC-KEY ENCRYPTION

In symmetric-key schemes, the encryption and decryption keys are the same.

It involves a single secret key which both the message-sender and the message-recipient must have.

It is used by the sender to encrypt the message and by the recipient to decrypt it.

Fig 1.0- SYMMETRIC-KEY ENCRYPTION

ASYMMETRIC KEY(PUBLIC KEY ENCRYPTION)

The term "asymmetric" stems from the use of different keys to perform these opposite functions.

It requires two separate keys one of which is secret (or private) and one of which is public.

The public key is used to encrypt plaintext and the private key is used to decrypt cipher text.

MODULES

We used three module in the project. (1) Input module. (2) Process module. (3) Output module.

INPUT MODULE In this module we implement attachment of file in the file security system. In this module we select the file type.

PROCESS MODULE

In this module we implement the process for the file security system like as encryption and decryption.

OUTPUT MODULE

In this module we save the encrypted file in memory.

ALGORITHM USE IN ENCRYPTION PROCESS

AES (Advanced Encryption Standard )

AES:-AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data.

The Advanced Encryption Standard (AES) is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001.

FLOW CHART OF AES ALGORITHM

REQUIREMENT OF SOFTWARE

Software:-The Software used in file security system are as follows:-

Operating System Windows NT/2000 (Client/Server) Front-end: Java JDK 1.4, J2Sdk 1.1.4, Swings.

REQUIREMENT OF HARDWARE

Hardware:-The hardware used in iris recognition are as follows:-

Pentium IV Processor with 1.9 GHz Clock Speed 512 MB RAM, 20 GB HDD, 32 Bit PCI Ethernet Card

SNAPSHOTS

SELECT THE FILE LOCATION

AFTER SELECT THE FILE

SELECTED FILE BEFORE ENCRYPTION

MESSAGE OF SUCCESSFUL ENCRYPTION

AFTER ENCRYPTION PROCESS FILE IS

SELECT FILE FOR DECRYPTION

AFTER DECRYPTION

AFTER DECRYPTION PROCESS THE FILE IS

CONCLUSION

A new simple tool has been created, which is targeted for use inside of a small institution such as a small university for lecturers’ daily use of sending exam files and sensitive material such that the material can be encrypted and the file is sent in one e-mail while the encryption key is sent in another e-mail or via any secure communication channel.
