Introduction

An automated teller machine (ATM), also known as a cash point (which is a

trademark ofLloyds TSB), cash machine or sometimes a hole in the wall in

British English, is a computerized telecommunications device that provides the

clientsof afinancial institutionwith access tofinancial transactionsin a public

space without the need for a cashier, human clerk orbank teller. ATMs are known

by various other names includingATM machine, automated banking machine, and

various regional variants derived fromtrademarkson ATM systems held by

particular banks.

need

Security of money, data is the most important issue in the world today. Our

project is based on security of ATM.

In this project we will simulate an ATM machine where dynamic computer

generated password are provided to user transaction.

As soon as user enters account number a new dynamic computer generated

password will be sent to users mobile phone on the number which is registered

at bank.

Using that auto generated password user will b able to login into the account.

After completing transaction when user logs out of the account, the password

will be automatically destroyed.

This way we can have a secure ATM transaction.

Existing System

The current existing atm system is based on a four pin static password process.

When the user inserts his/her atm card, in the machine,

he/she needs to enter his/her permanent four pin password registered at the bank.

After the password is been accepted, the user logs in and can make transactions.

Once the transaction process is over the user can login again any number of times

using the same static four pin password registered at the bank.

A detailed process is required to change the current static password in case of any

uneven circumstances.

Recently, new features are being introduced by certain banks to allow additional

privileges such as payments of bills, mobile recharges etc. with the use of atm

card.


12/30

Problem statement

Since the existing system consists of a static four pin password, its confidentiality

being confined only to its authenticated user, is at bay.

5.1 Eavesdropping:-

Password of a user can be spied upon and can be accessed easily by obtaining the

card by faulty means.

5.2 Spoofing:-

There is a possibility that, when a user enters its password during a transaction

process, a hacker fakes as the authorized site and prompts the user to re-enter the

password due to a system error.

When the user complies with the instruction the hacker stores the data and uses it

for his future peccadilloes intentions.

This leads to a man-in-the-middle attack.

5.3 Brute-force attack:-

Using the brute force if we try to crack the current static four pin password it can

be done in 9999 attempts, thus weakening the security.


13/30

Proposed system

In the proposed system we will simulate an ATM machine where an 8-pin

dynamic computer password is being generated and provided to user for every

single transaction process.

As soon as user enters account number a new dynamic computer generated

password will be sent to users mobile phone on the number which is registered at

bank.

Using that auto generated password user will b able to login into the account.

After completing transaction when user logs out of the account, the password will

be automatically destroyed.

This way we can have a secure ATM transaction.

6.2 Advantages of the proposed system over the old existing system:-

Since the old system consists of four pin static password eavesdropping is

a major issue there.

This issue is very efficiently solved in the new system since it uses dynamic

generation of passwords

Problem of spoofing is eradicated since the dynamic passwords are valid

only for a single transaction process.


14/30

In simple systems, using brute force we can crack the password in 9999

attempts whereas in the proposed system the same will required 99999999

attempts which is extremely difficult.

7. Scope of system

We have to implement both ATM client and server and simulate the basic

transactions of the Automated teller machine.

- ATM simulator and server project will be divide into two phases. Firstphase will concentrate on develop the back-end server, the centralizationof all of the transactions. Second phase will be developed the front-end

ATM. In addition, we have to simulate both the interface and hardware of

an ATM.

- To use ATM, customer place their card into card reader and the customer

only need to input the PIN number. The session is started when customer

place their cart into card reader and finish when customer press reject

button on ATM to get the ATM card back.

- ATM Client should be able to support both console and graphical

interface. In order work, the project should have the reusability, follow the

OO principal and keep in mind: close for modification but open forextension.

7.2 The client side consists of following module:-

7.2.1

Starts Session To start using an ATM, the customer inserts their card. They

only need to enter a Personal Identification Number (PIN) for verification afterreceiving the dynamic password on the registered mobile number.

7.2.2

Check BalanceGet the balance of an account. The user can also get a balance

of all accounts linked to the card.

-

7.2.3

Withdraw CashA customer can withdraw cash from an account. An exchange

is required if the currency withdrawn isnt the same as the account

being withdrawn from. If the customer has multiple accounts, the customer is ableto choose which account to withdraw from.

7.2.4

Issue Demand Draft The customer can issue a demand draft from with help ofatm machine.

to finish their session. The ATM will return their card.


17/30

7.3 The admin side consists of the following module

7.3.1

Register accounta new acc/user is being registered by the admin at the backend.

7.3.2

Update accountall the transactions of the user are being updated and saved

by the admin.

7.2.3

Delete accountaccount can be deleted on request.

7.3.4

View fixed deposit logthe admin keeps the track of the fixed deposit account

and on request create new fixed deposit for the user.

7.3.5

View cheque book request - checks any new requests for cheque book.

7.3.6

View Cheque statuschecks the current status of an issued check.

7.3.7

Bill detailsprocesses the payments of bills requested by the user.

Methodology

We are implementing a classical waterfall model to to model our atm simulator


19/30

8.2 overview of a waterfall model:

The waterfall model usually includes the following processes:

Problem definatin

Feaseability study

Requirenments anaysis

Design

Programming and module testing

Integration and system testing

Delivery

Maintainance

8.3 system development

Preliminary investigation

Feasibility study

Main aim : to understand the problem and determine the

issues involved and how to tackle them.

Technical feasibility: to investigate whether thetechnology exists to implement the proposed system, or

wether it is a practical proposition.


20/30

Economic feasibility: if the prosposed system is cost

effective or not. that is if benefits do not outweight

costs,tis not worth going ahead.

Opeartional feasibility: determines if current work practices and

procedures are adequately supported by the new supported by the

new system; how change affects the working life of workers.

Requirements specification

A requirement may range from high-level abstract statement of a

service or a system constrain to a detailed mathematical function.

In this module the basic requirements of the system must be

understood such as information domain, function, behavioral

requirements of the system.

Functional requirements

Describe functionality or system services.

Depend on the type of software, expected users and type of

system where the software is used.

The maybe high-level statements on what the system

should do.

Functional system requirements should describe the system

in detail.

Non functional requirements

These define system properties and constrains.


21/30

Maybe more critical then functional requirements as in if

they are not met, renders the system useless.

Functional

- Transfer money from one account to another

- Deposit money into specific account

- Withdraw money from an account

- Exchange money as an extra step to deal with foreign currency.

- Check account balance

Non-Functional

- Graphic user interface friendly- Database system management
