1. INTRODUCTION

India is one of the world’s largest democracies with the

community of 1 billion. India has an electorate of around 700

million persons. Voting theory began formally in the 18th

century and proposals for voting system are been made ever

since. The current voting mechanism has many security

problems. The past experience of electoral process enforced

to focus on the use of latest technologies in e-voting process.

The development of voting system can be in the field of

additional security in authentication process. The

improvisation in the current voting system can be made using

biometric technology. Biometric recognition refers to the use

of fingerprint, Iris, face palm and speech characteristics.

These are called Biometric identifiers. Fingerprint matching

play an important role in this project. Today, it is mandatory

for every citizen to have Aadhar card in which fingerprint and

iris of individuals are stored. In this paper, Raspberry pi and

fingerprint scanner which is used to store the images of

fingerprint in a database.

At the time of voting he/she places his/her fingerprint, if it

matches with already stored one in a database then he/she will

proceed for voting. If the same person tries to vote twice, the

buzzer buzzes indicating the bogus voting. So this kind of

practices can be prevented by this system.

1.1 Paper Based Voting

As far as India is concerned, voting system began in the 18th

century itself. There are various voting methods available

according to its development with technologies.

Paper based voting has been used since long time before the

advent of internet. A ballot is a device used to cast votes in an

election. In this method they used a piece of paper for voting

which included the decisions made by the voter.

In simple elections ballot may be a simple scrap of paper on

which each voter writes the name of the candidate. This

method requires of presence of person in the booth to choose

their candidate through paper and put the paper in the ballot

boxes.

Drawbacks

a) It is very difficult to collect the ballot boxes and transport to

main centres.

b) Errors may occur during manual counting.

c) Need more man power for security.

d) Need more time to vote.

e) Chances of invalid voting.

f) Need more time for counting.

1.2 E-Voting

E-voting is the voting process electronically, without the use

of paper and ballot boxes. In this system, election data is

recorded, stored and processed primarily as digital

information. It is defined as any voting process where an

electronic means is used for votes casting and results

counting. E-machine consists of buttons and symbols of

respective candidate which when pressed the count of votes

get stored in the EVM. But still, there is a practice of fake

votes in this system. So, further development should be

implemented to prevent these kinds of activities.

Drawbacks

a) Security problems- One can change the program installed

in the EVM and can change the result after the polling.

b) Illegal voting which is faced in every electoral procedure.

One candidate casts the vote of all members in the electoral

list illegally. This results in loss of votes for other candidates

participating in election.

2. BIOMETRICSYSTEM

The main focus of the proposed system is the use of

fingerprint image of a voter to authenticate him/her and to cast

the vote very securely. A biometric system is a pattern

recognition system that operates by acquiring parametric data

AB ST RACT

This paper proposes the need of authenticated voting system in our election due to the increase in illegal voting or bogus voting in Loksabha and

Rajyasabha election. Here the authentication of an individual is done using biometric and eligibility of the voter is verified using the Aadhar card. In

this project, the database stored in the Aadhar card provides the reference data. Moreover, added tier of security is enforced as biometrics. The key

functions of this paper are enrolment and matching. Initially, the voters’ fingerprints are enrolled and stored. Once the fingerprints are stored it can be

retrieved at any time for authentication. During election, when the voter keeps his/her fingerprint the already stored Aadhar card details will be

displayed from the database. An individual’s details can be deleted from the database if not required. The use of biometric requires less man power,

save much time for voters and personnel, ensures accuracy, transparency and avoids bogus voting.

Keywords: Fingerprint, biometric, Aadhar card and authentication.

of an individual. It can be used either in the verification mode

or identification mode. Identity verification is typically used

for positive recognition, where the aim is to prevent multiple

people from using the same identity. In the identification

mode, the system recognises the individual by searching the

identities in the database for a match. Therefore, the system

conducts one-to-many comparisons to establish an

individual’s identity.

A biometric system is designed using the following four main

modules.

Sensor module: This captures the biometric data of an

individual. An example is a fingerprint sensor that images the

full structure of a user’s finger.

Feature extraction module: Here, the biometric data is

processed to extract a set of salient features.

Matcher module: Here, the feature is extracted during

recognition are compared against the stored templates to

generate matching scores. Example, the fingerprint-based

biometric system.

System database module: It is used by the biometric system

to store the biometric templates of the enrolled users.

3. PROPOSED SYSTEM

The main components of the voting system is listed as

follows,

1. Arduino mega 2560

2. Fingerprint Identification Module

3. PC

4. Power supply

3.1 ARDUINO MEGA 2560

The mega 2560 is a microcontroller board based on the

Atmega 2560. It has 54 digital input/output pins of which 15

can be used as PWM outputs. 16 analog inputs, 4 UART’s

(hardware serial ports), a 16 mega Hertz crystal oscillator.

A) Power-The mega 2560 can be powered via the USB

connection or with an external power supply. The power

source is selected automatically.

B) memory-It has 250 KB of flash memory for storing code, 8

KB of SRAM and 4KB of EEPROM.

3.2 Fingerprint Sensor

Fingerprint processing includes two parts: fingerprint

enrolment and fingerprint matching. When enrolling, user

needs to enter the finger two times. The system will process

the two time finger images, generate a template of the finger

based on processing results and store the template. When

matching, user enters the finger through optical sensor and

system will generate a template of the finger and compare it

with templates of the finger library.

Hardware connection

Via serial interface, the Module may communicate with MCU

of 3.3V or 5V power: TD (pin 3 of P1) connects with RXD

(receiving pin of MCU), RD (pin 4 of P1) connects with TXD

(transferring pin of MCU). Should the upper computer (PC)

be in RS-232 mode, please add level converting circuit, like

MAX232, between the Module and PC.

3.3 Personal Computer

Here the PC is used to store the database of the voters and is

programmed using visual basics. It is also used to display the

details of the voter when the finger print is recognized.

3.4 Power Supply

Power supply is an essential component for the processing of

entire system. Arduino mega 2560 requires a voltage of 5 volt

and minimum current of 700mA to work. In this project we

have decide to use Samsung USB charger with power supply

5V/2A.

Working

The data base is created using visual basic studio which

contains the Aadhar card details of the voter. When the voter

keeps his fingerprint it is checked with the already stored data

base. If the finger print is recognized then the voter is allowed

to vote.

4. CONCLUSION

This project is to develop an authorised voting system. The

Aadhar card detail creates a unique profile of the individual to

avoid bogus voting. So only the eligible candidates can cast

their votes in the election. This project also reduces the man

power and enhances the security.
