INTRODUCTION

• This project is designed for electronic voting machine by using the

fingerprint identification method.

• Here voters thumb impressions are used for identifying the voters.

• During voting when the voter keeps his/her thumb in the scanner,

the system will check whether it matches with pre stored

impressions in the database.

• If it matches then system will allow the voter to poll his vote and

otherwise prevent the voter from polling.

Why only Fingerprint ?

• Every person in this universe has unique fingerprint.

• Fingerprints are unique i.e. everyone is born with one, which states that fingerprints can be used for unique identification.

• Fingerprint scanner is a device for computer Security featuring superior performance, accuracy, durability based on unique NITGEN Fingerprint Biometric Technology.

• Fingerprints tech is widely used in banking, authentication etc…

• Reliable and trusted

Hence we opted for fingerprint technology in our project.

Microcontroller (AT89S52)

• A Micro controller development of reduces PCB size & cost of design .

• If a system is developed with a microprocessor, the designer has to go for external memory such as RAM, ROM, EPROM and peripherals.

• Which is Because it has 8 Kb on chip flash memory use sufficient for our application.

• Moreover ATMEL is the leader in flash technology in today’s market place and hence using AT 89S52 is the optimal solution.

MAX 232

• It is 16-Pin IC known as Voltage Converter or Line Converter.

• It converts the RS-232 levels of the Fingerprint Scanner to the TTL voltage levels of µC 8051.

• MAX Maxim Company232 Series number

• RS Recommended Standard was set by the Electronic Industries Association (EIA) in 1960.

• Using DB-9 (Data Bit) Pin connector, we’ll connect the MAX-232 to the Fingerprint Scanner.

• We can connect two devices at a time to the MAX-232.

Sub-Units of EVM

Features of AT89S52 :

• The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller.

• 4.0V to 5.5V Operating Range

• Fully Static Operation: 0 Hz to 33 MHz

• 256 x 8-bit Internal RAM

• 32 Programmable I/O Lines

• Three 16-bit Timer/Counters

• Eight Interrupt Sources

• Low-power Idle and Power-down Modes

• Fast Programming Time

Pin Description :

Fingerprint Scanner (NITGEN FIM 3030)

• The fingerprint scanner used here is NITGEN company based which is

the leading manufacturer of FIM(Finger identification Module)

• The methodology involves of storing the fingerprint images as

database and during voting the input image is matched using the

database

LIQUID CRYSTAL DISPLAY(LCD)

• The LCD display is used to display the messages during

the action.

• Here a 16x2 display is used, each character is made of

5x7 dot matrix.

• Displays have built in backlight(blue or green diodes)

ADVANTAGES

• Low power consumption

• It is economical

• Less manpower required

• Time conscious, as less time required for voting and

counting

• Avoids invalid voting.

• Saves transportation cost due to its compact size.

• Convenient on the part of voter.

• EVM are no different than websites or software; they can be

penetrated and altered by a hacker.

• Overall cost is high, physical tampering could be possible.

• Computer software and systems can have problems that may

delay or even halt voting.

DISADVANTAGES OF EVM

LIMITATIONS

• The limitations of this projects are:

• The collection of fingerprints of all the voters is little difficult.

• Only fingerprints of the voters is identified instead of

identifying the persons

Conclusion

• The project “ELECTRONIC VOTING MACHINE USING

FINGERPRINT Tech” has been successfully designed and tested.

• This can bring a revolutionary change in the election procedures.

• It provide additional security.

• System completely reduces the chance of invalid votes.

• The system can be manufactured simply as well as cheap.
