What is Biometrics?• The study of automated identification, by use of

physical or behavioral traits.

Physical and Behavioral:

Advantages:

Biometrics has no risk of Forgetting itGetting in stolenGetting it copiedBeing used by anyone else

Biometric system process flow:

Why fingerprint biometric:

High UniversalityHigh DistinctivenessHigh PermanenceHigh PerformanceHigh Acceptability

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

other5% population

Power Supply:

Most digital logic circuits and processors need a 5 volt power supply.

we use a LM7805 voltage regulator IC.

Fingerprint scanner:

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

MAX 232

To connect any RS-232 to a microcontroller converters such as MAX232 is used.

Bit 1 for -3v to -25vBit 0 for +3v to +25v

Buzzer: Informs when any unauthorized

person.

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.

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 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.

 

Working process:

If a person enters in an ATM/Bank,he has to scan his fingerprint. If it matches ,he goes for transactions.

Otherwise if any unauthorized

person enters then alarm sound will be

Heard from buzzer.

Software Components:

KEIL IDEEXPRESS SCHEmbedded C

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

Conclusion:

The microcontroller based system for securing the transactions of the user and providing the security for the locker system and even more for the PASSPORT verification using a finger print scanner has been followed.
