ABSTRACT

The aim of this project is that it is used for ATM access cash withdrawal with more security. we use

biometric system for highly secure transaction. We use fingerprint system and One Time Password

(OTP) is send to the user registration mobile number through GSM Module system. After that, user

will be able to complete the transaction securely.

KEYWORDS: Fingerprint Scanner, GSM Module, AT89S52 Controller, Motor.

INTRODUCTION:

The aim of this project is to used for ATM access cash withdrawal with more security. In this system,

Bankers will collect the customer finger print and mobile number while opening the account then

customer can access ATM machine.

The working of system will start when a customer goes at ATM center. First there is switch for entry

after getting entry customer has to place his finger on the finger print module then system will check

for user identity and checks validity of finger if it find as a valid then system will automatically

generates another different 4 digit code i.e. OTP and that code will be message to the customer

registered mobile number through GSM module which is connected to AT89S52 Controller.

Here customer has to enter this code again after entering OTP system will checks whether enter code

is valid or not and if it is valid the customer allow for further accessing. If OTP is not valid then user

will get message like “Location of the ATM”. If users want to enquiry then he or she will go to the

located ATM and get information about the last transaction.

HARDWARE DESIGN:

The design of entire system consisted of two part which are hardware and software. The hardware are

designed by the rules of embedded system, and the steps of software consisted of three parts. The

more details are shown as follows. A. Hardware Design The S3C2440 chip is used as the core of

entire hardware. Furthermore, the modules of LCD, keyboard, alarm, fingerprint recognition are

connected with the main chip (S3C2440).The SRAM and FLASH are also embodied in the system.

There are some modules consisted of the system as,

1. LCD module: The OMAP5910 is used in this module as a LCD controller, it supported

1024*1024 images of 15 gray-scale or 3375 colors.

2. Keyboard module: It can be used for inputting passwords.

3. SRAM and FLASH: The 16-bit 29LV160BB- 70REC of FLASH chip and the 32-bit

HY57V561620CT-6 of SRAM chip are connected with the main chip. Their functions are

storing the running code, the information of fingerprint and the algorithm.

4. Fingerprint recognition module: Atmel Company's AT77CI04B be used as fingerprint

recognition. It has a 500dpi resolution, anti-press, anti-static, anticorrosion.

5. Ethernet switch controller: RTL8308B can provides eight 10/100 Mbps RMII Ethernet ports,

which can connect police network and remote fingerprint data server.

Before using the ATM terminal, the client's fingerprint feature will be connected to the remote

fingerprint data server to match fingerprint data with the master's, if the result isn't correct, the system

will call police automatically and send alarm to the credit card owner. The block diagram of hardware

design is shown in figure.

SOFTWARE DESIGN:

The design was component of three parts included the design of main program flow chart, the

initializing ones, and the algorithm of fingerprint recognition flow chart. This system of software is

implemented by the steps as follows: first of all, the Linux kernel and the File system are loaded into

the main chip. The next, the system is initialized to implement specific task, such as checking ATM

system, GSM communication and so on, and then each module reset for ready to run commands.

Before using ATM terminal, the mobile number and fingerprint of the customer is required.

Figure-2 Flow chart 1

First the system is required the owner's fingerprint. If all the recognition is right, the system would

send password to the Account holder and he will enter the same password in touch screen for

accessing the ATM Terminal. If Authentication Failure then it send the alert message to the Account

holder and Bank. The overall flow chart of software is shown in figure 2.

In the process of inputting fingerprint, the AT77CI04B which is a linear sensor that captures

fingerprint images by sweeping the finger over the sensing area, will used for acquiring the image of

fingerprint. This product embed true hardware based 8- way navigation and click functions. The

fingerprint information will be temporarily stored in SRAM and upload to the remote finger data

server to compare through bank network. The result of process will be controlled by main chip.

The flow chart of fingerprint recognition the initializing process means that set the hardware and

software and then start the multiple mission modules, each module will be started according to the

priority processes. At first, initialize the system clock, and execute the codes of open interrupt and the

open interrupt task. Then, the system would judge and enter process of module. Finally, the system

would start to attempt multiple tasks.

ADVANTAGES:

1. The GSM technology is cellular network, which means that mobile phones connect to it by

searching for cells in the in the immediate vicinity it will make the authentication fast.

2. The fingerprint recognition will make the system so secure.

3. The nominee user also used so instead of the main user the nominee will access the account in

case of emergency.

4. The one time password sends by GSM modem to the main user changes every time so it provide

good security.

5. Other advantage of the system validation functions. Pin validation, fingerprint validation and one

time password are made it is one of advantage of the system.

RESULTS & CONCLUSIONS:

The Implementation of ATM security by using fingerprint recognition and GSM MODEM took

advantages of the stability and reliability of fingerprint characteristics. Additional, the system also

contains the original verifying methods which was inputting owner's password which is send by the

controller. The security features were enhanced largely for the stability and reliability of owner

recognition. The whole system was built on the technology of embedded system which makes the

system more safe, reliable and easy to use.
