3. What is Biometrics?
• The study of automated identification, by use of
physical or behavioral traits.

4. Physical and Behavioral:

5. Advantages:
Biometrics has no risk of
 Forgetting it
 Getting in stolen
 Getting it copied
 Being used by anyone else

6. Biometric system process flow:

7. Why fingerprint biometric:
 High Universality
 High Distinctiveness
 High Permanence
 High Performance
 High Acceptability

8. 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

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

12. Fingerprint scanner:
 A fingerprint sensor is an electronic device used to
capture a digital image of the fingerprint pattern.

13. MAX 232
 To connect any RS-232 to a microcontroller
converters such as MAX232 is used.
 Bit 1 for -3v to -25v
 Bit 0 for +3v to +25v
Buzzer:
 Informs when any unauthorized
person.

14. 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.

15. 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.

16. 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.

17. 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.

18. Software Components:
 KEIL IDE
 EXPRESS SCH
 Embedded C

19. 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

20. 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.
