1. Introduction

1.1. Purpose This System is based on FINGERPRINTING to carry out transaction process.

It aims at removal of ATM’s, user directly carries out transaction in need and there

is no need of hand cash.

BANK creates Database of every user’s fingerprint and therby every user can carry

out transaction whenever needed.

It also ensures safety as well as security to the USER.

1.2. Document Conventions

The following are the list of conventions and acronyms used in this document and the

project as well:

TRANSACTION SYSTEM: DATABASE of every user including his/her fingerprint as well as

bank records.

User: Person who carries out transaction.

SCANNER: Machine to carry out transaction.

1.3. Scope Scope of this project is very broad in terms of other security of user.

Few of them are:-

_ HandCash is not required by the user.

_ Easy and safe transaction everytime for the user.

_ E-shopping and every other mean where transaction need to be done will be carried

out by FingerPrint based Transaction.

1.4. References

This web application has been prepared on the basis of discussion with Team

Members and also taken information from website.

2. Overall Description 2.1. Technology Perspective The proposed FingerPrint based Transaction is one of the transaction method.

FingerPrint based Transaction has following attributes:

Database of bank

User’s fingerprints

Transaction Authentication

DATABASE OF BANK:-

Database of bank means it has all records and information about the user. It consist of

user’s info such as name, bank id, bank accounts, account type and so on. This

technology is addition to past technology with addition of user’s fingerprint which

makes this technology so efficient and secure.

USER’S FINGERPRINT:

User’s fingerprint is also a part of database. This fingerprints are required when there is

need to carry out transaction. Every transaction is validated by fingerprints of the

corresponding user. While carrying out transaction every user need to SCAN his/her

fingerprint on the machine.

4

TRANSACTION AUTHENTICATION:-

This is the step which authenticates the transaction i.e whether valid or invalid user is

carrying out the transaction through his/her fingerprint’s and this step makes

transaction process secure and safe.

2.2. Need of this Transaction System

These are following reasons why this technology is needed.

To carry out safe and secure transaction.

Safe transaction along with the validation

Hand cash is not needed by the user.

It indirectly removes need of ATM and ATM card.

3. System Features

3.1. TECHNICAL FIELD

The present invention relates to a fingerprint identification system using a fingerprint for

identification of persons and more particularly to a fingerprint identification system in

which a fingerprint identifying function is added to an operating system (“OS”) of an

electronic money transfer system, or the fingerprint is used as a key for a door or the

like, or the fingerprint is encoded into a cipher key.

3.2. CLAIMS:

What is claimed is: 1. An electronic money transaction systems terminal for communication with like terminals utilizing an encoded message encoded with a first identification code of characteristic fingerprint points including minutiae comprising: a computer located at a site of the transaction, a money conversion module located at the site of the transaction for converting monetary values to and from electric values to permit authorization of the transaction, a connection between the money conversion module and the computer at the site of the transaction and, a fingerprint identifying apparatus including a fingerprint input data panel connected to said money conversion module at the site of the transaction the money conversion module having: an input through the connection to the computer located at the site of the transaction for permitting the reception of the encoded messages encoded with the first identification code of characteristic fingerprint points including minutiae a microprocessor unit connected to be operable at a read only memory (ROM) system, and through the ROM operating system adapted to convert received fingerprint data to an identification code of characteristic fingerprint points including minutiae and to encode and decode messages with a code including the first identification code from the fingerprint input data panel and the characteristic fingerprint points including the minutiae and an output through the connection to the computer located at the site of the transaction for permitting the transmission of encoded messages with the first identification code of characteristic fingerprint points including minutiae the fingerprint identifying apparatus including a fingerprint input data panel having a read and write memory to a database of fingerprint data of at least one human fingerprint for generating the first identification code of characteristic fingerprint points including minutiae and, the fingerprint input data panel for obtaining fingerprint input data from a finger impressed on the fingerprint input data panel and inputting the fingerprint data to the read and write memory for receiving fingerprint input and data.

4. Software Interface

The FINGERPRINT based scanner network has to provide software interface to

• The software used by different banks • Different network software

The exact, detailed specification of the software interface is not part of the document.

4.1. Communication Interface There is no restriction of the Fingerprint based scanner network to a specific network

protocol as long as the performance requirement are satisfied.

4.2. Performance Requirements Performance requirement 1

• Description Error message should be displayed atleast for 30sec.

Performance requirement 2

• Description If there is no response from the bank computer after within 2minutes the card is rejected with an error message

Performance requirement 3

• Description Each bank may be processing transactions from several FINGERPRINT based scanner at the same time.

4.3. Other Requirements The FingerPrintbased transaction scanner must be able to use several data formats according to the data formats that are provided by the data bases of different banks. A transaction should have all the properties of a Data base transaction (Atomicity, Consistency, Isolation, Durability)
