FINGERPRINT BASED ELECTRONIC VOTING SYSTEM

The main aim of this project is to avoid rigging completely. Electronic voting systems have come

into picture to prevent rigging upto the maximum extent. But even there may be some malfunctions

during elections. Thus, fingerprint based electronic voting system has been designed.

According to ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly

include fingerprint, face, iris, voice, signature, and hand geometry recognition and verification. Many

other modalities are in various stages of development and assessment. Among these available biometric

traits, Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable.

The present scenario to operate a bank locker is with locks which are having keys. By this we can’t say

that we are going to provide good security to our lockers. To provide perfect security and to make our

work easier, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and

BIOMETRICS.

Firstly discussing about Biometrics we are concentrating on Fingerprint scanning. For this, we

are using FIM 3030N high voltage module as a scanner. This module has in-built ROM, DSP and RAM. In

this, we can store the fingerprints of up to 100 users. This module can operate in 2 modes i.e., Master

mode and User mode. We will be using Master mode to register the fingerprints which will be stored in

the ROM present on the scanner with a unique id.

When a person wants to register himself in the voter list, he has to provide his complete details

along with his fingerprint image. Thus, when the same person comes to poll his vote during the

elections, he needs to give his fingerprint image before polling his vote. Thus, the system scans his

fingerprint image, compares the image with the already stored image. If both the images are matched,

the person can enter into the room to poll his vote.

The door will be opened when the switch is pressed by the polling officer. If not, the system

simply alerts the buzzer not allowing the voter to poll his vote. LCD is used to display the related

messages.

This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is

used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary

of 230/12V step down transformer.
