Abstract-In this paper biometric finger-vein recognition
(FVR) system for authentication on ATM network is
proposed. The system is implemented on the basis on
embedded platform and equipped with a novel finger-vein
recognition algorithm and implemented in MATLAB
platform .The proposed system consists of three hardware
modules: image acquisition module, embedded main board,
& human machine Communication module. The structure
diagram of the system, the image acquisition module is used
to collect finger-vein images. The Embedded main board
including the LPC2148 Microcontroller chip, memory
(flash), and communication port is used to execute the
finger-vein recognition algorithm and communicate with the
peripheral device. The human machine communication
module is used to display recognition results and receive
inputs from users. Here we developed ATM security concept.
If finger vein matched, means transaction successful
displayed on pc screen. GSM technology is used and one time
password is generated.

So only we designed a system which helps us to use the
ATM machine without the ATM card.

INTRODUCTION
The Biometric is defined as the automated recognition of
individuals based on their biological or behavioral
characteristics. The finger-vein detection has been
proved to fully comply with this definition and it
provides many important biometric features:
Uniqueness and permanence of the pattern
Almost impossible to forge or copy.
The biometric parameter is hidden from general view.
ATMs have become very popular with the general
public for their availability and general user friendliness.
Here we introducing the concept of ATMs network
security by using biometric finger-vein pattern.

EXISTING SYSTEM
Today, security is very much important concept in all
kind of activities. Illegal activities are happening in
every place today. So government and corporate sections
are concentrating mainly on the security levels with their
every invention. Existing ATMs are convenient and easy
to use for most consumers. Existing ATMs typically
provide instructions on an ATM display screen that are
read by a user to provide for interactive operation of the
ATM. Having read the display screen instructions, a user
is able to use and operate the ATM via data and
information entered on a keypad. However the drawback

algorithm
According to this flow chart the input finger vein images
are matched with database images and displayed person
is authorized or unauthorized on pc screen. Only when
the image matches it asks the pin number and further
processing starts. Otherwise the process is terminated.
So by using this system need of ATM card is completely
eliminated we can operate the ATM machine.

Finger vein recognition is very effective when compared
with pattern recognition, pin number security the other
type of Biometric security methods like finger print
security, palm print security, image scanning and some
recognition techniques. In this FVR system, we are
focusing on high security with RFID technology. In
FVR system, the RFID module is used to collect the user
data base. This RFID will reduce the complexity of the
image acquisition module.
performance and very low power consumption. The
ARM architecture is based on Reduced Instruction Set
Computer (RISC) principles, and the instruction set and
related decode mechanism are much simpler than those
of micro-programmed Complex Instruction Set
Computers.

Fig.3. Receiver Unit
In this section, RF receiver module is attached with the
embedded control unit. This unit receives the secret
digital data from the transmitter unit and it will be given
to the controller. In the FVRS recognition unit, vein
images will be stored in the image acquisition module. If
RF receiver receives any digital code, then automatically
code verification will be done inside the embedded
control unit. If the code is matched then an asynchronous
command will be given to the image acquisition module.
Then the vein image comparison will be done inside the
processor. If the image is matched then automatically the
device will go to its working state. In this ECU is
interfaced with a GSM module. With this module we can
develop the one time password (OTP) system. It will
make a very effective security to the user. It will play an
effective authentication process. This mobile GSM
communication module will not only send the intimation
for authorize but also for unauthorized.

Radio Frequency, any frequency within the
electromagnetic spectrum associated with radio wave
propagation. When an RF current is supplied to an
antenna, an electromagnetic field is created that then is
able to propagate through space. Many wireless
technologies are based on RF field propagation.
Transmitter: The TWS-434 extremely small, and are
excellent for applications requiring short-range RF
remote controls. The TWS-434 modules do not
incorporate internal encoding. The transmitter output is
up to 8mW at 433.92MHz with a range of approximately
400 foot (open area) outdoors.
HARDWARE REQUIREMENTS
A. ARM Processor
The LPC2141/2/4/6/8 microcontrollers are based on a
32/16 bit ARM7TDMI-S CPU with real-time emulation
and embedded trace support, that combines the
microcontroller with embedded high speed flash
memory ranging from 32 kB to 512 kB. 128-bit wide
memory interface and unique accelerator architecture
enable 32-bit code execution at the maximum clock rate.
For critical code size applications, the alternative 16-bit
Thumb mode reduces code by more than 30 % with
minimal performance penalty. Due to their tiny size and
low power consumption, LPC2141/2/4/6/8 are ideal for
applications. The ARM7TDMI-S offers high

Receiver: RWS-434: The receiver also operates at
433.92MHz, and has a sensitivity of 3uV. The WS-434
receiver operates from 4.5 to 5.5 volts-DC, and has both
linear and digital outputs. A 0 volt to Vcc data output is
available on pins. The receiver’s output will only
transition when valid data is present. In instances, when
no carrier is present the output will remain low.

Step4: Matching
After authentication the main part of transaction is
comes which is important part of this work. When
person is authorized the PIN No. is send to mobile no.
By using that no. person can easily access ATM in
secure way.
