This document discusses using fingerprint biometrics for authentication in ATM machines. It defines ATMs and outlines issues with current identification methods like stolen cards and shared PINs. Fingerprint biometrics could solve these issues through multi-factor authentication combining cards, PINs, and fingerprints. The document then covers fingerprint patterns, how fingerprint scanners work to enroll and verify prints, and the system design of a biometric ATM including hardware and software components. Potential advantages are discussed like increased security over shared passwords, with disadvantages including higher costs.

3. Definition Of ATM
ATM (Automated Teller Machine) the three
letters themselves from quite a convenient term.
Now that these three letters have become an
inseparable part of modern economics.
ATM is an electronic device that
enables customers of financial instructions to
perform certain basic financial transactions like
cash withdrawal without the aid of a cashier or
clerk.
when customers use their ATM cards
for any financial transactions, they can access
their bank deposits or credit accounts to perform
the same. Through an ATM card, a customer
can perform transaction like cash withdrawal,
mobile recharge, online shopping etc.

4. How ATM identifies customers
The most important tool required to
operate an ATM is a debit card or credit
card from the respective banks. These debit
or credit cards have magnetic stripes, card
verification value (CVV) code and unique
card number specific to each customer.
With the help of theses three factors ATM
can identify each customer. However, the
authentication to perform any transaction
is to be given by the customer with his or
her Personal Identification Number(PIN)

5. Issues In Current ATM Networks
• ATM Card frauds
• Use of ATM card duplicators
• Card sharing by family and friends
• Inability to trace the wrongful users
• ATM PINs can be shared on phone or recorded using secret cameras

6. Biometric ATM Solve These Issues
• Single/Multi factor Biometric Authentication: Fingerprint, Iris, Face, Pal vein
• Multifactor Authentication: Card + PIN + Biometrics
• Online or offline Authentication using smart cards
• Card less Authentication
• Biometrics is combination of card or PIN

7. What is Biometrics ?
• The meaning of Biometrics comes from the Greeks.
Biometry = bio(life) + metry(to measure).
• Biometrics is the science and technology of measuring and analyzing biological data.
• The first known example of biometrics in practice was a form of finger printing being
used in China in the 14th century.
• Biometrics refers to technologies that measure and analyze human body
characteristics such as DNA, fingerprints, eye retinas and irises, voice patterns, facial
patterns and hand measurements for authentication pur5poses.

9. How Biometrics Works ?
• Biometrics systems work by recording and comparing biometric characteristics.
• When an individual first uses a biometric system, their identifying features are
enrolled as a reference for future comparison. This reference may be stored in a
central database or on a card (or both) depending on the needs of the
application.

10. Why Fingerprint Biometric
High Universality
High Distinctiveness
High Permanence
High Performance
High Acceptability

11. Fingerprint pattern
LOOPS:
Ridge lines enter from one side and curve around to exit from the same side.
60-65%of population.
WHORLS:
Rounded and circular ridge pattern.
30-35% of population.
ARCHES:
Ridge lines enter from one side print and exit out the other
5% population

12. Intro-fingerprint Authentication
Enrollment and verification process of fingerprint

13. Fingerprint Scanner
A fingerprint sensor is an electronic device used to capture a digital image of the
fingerprint pattern.

15. Power Supply:
Most digital logic circuits and processors need a 5 volt power supply.
we use a LM7805 voltage regulator IC.
Hardware Component

16. Microcontroller
A Micro controller consists of a powerful CPU tightly coupled with memory RAM, ROM or
EPROM),
various I / O features such as Serial ports, Parallel Ports, Timer/Counters, Interrupt Controller, Data
Acquisition interfaces-Analog to Digital Converter (ADC), Digital to Analog Converter (ADC),
everything integrated onto a single Silicon Chip.
 To connect any RS-232 to a microcontroller converters such as MAX232 is used.

17. Key pad:
We are using two types of keypads
The matrix keypad and
 other is the normal key for selecting the mode of operation.
LCD:
Output device
Clearly displayed on the LCD.
Locker system:
 DC motor as the Locker for the authorized persons in the Locker system mode.
EEPROM:
 This is the additional memory which we are using for the storage of the data for a particular person.

20. Advantage
• While a criminal might be able to obtain a password illegally, getting a user's
fingerprints would be much more complicated.
• In addition, contrary to traditional id cards or badges, you can't actually lose
physical features, making maintenance more cost efficient for the business or
organization, and the technology more convenient for users.

21. Disadvantage
• Biometric identification machines are traditionally more expensive to buy than
traditional ones.
• Biometric identification machines are not always entirely accurate. For example,
an individual with a cold may not be able to identify himself using a voice
identification device.

22. Future Scope
Performance can be increased in terms of speed and memory.
A speaking voice alarm can be used to indicate unauthorized person
accessing the ATM.
The system can be made to communicate with modems or mobile
phones

23. Conclusion
Biometric tokens are the safest means of preventing ATM frauds.
• The main reason for introducing biometric systems is to increase overall security.
• Biometrics offers greater security and convenience than traditional methods of
personal recognition.
• In some applications, biometrics can replace or supplement the existing technology. In
others, it is the only viable approach.
• The biometric system is only one part of an overall identification or authentication
process, and the other parts of that process will play an equal role in determining its
effectiveness
