Definition Of ATMATM (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.

How ATM identifies customersThe 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)

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

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

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.

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.

Fingerprint patternLOOPS: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 other5% population

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

Power Supply:Most digital logic circuits and processors need a 5 volt

power supply.we use a LM7805 voltage regulator IC.

Hardware Component

MicrocontrollerA 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.

Key pad:We are using two types of keypadsThe matrix keypad and other is the normal key for selecting the mode of operation.

LCD:Output deviceClearly 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.

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.

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.

Future ScopePerformance 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

ConclusionBiometric 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
