A CASE STUDY ON SECURED EMBEDDED VOTING SYSTEM USING BIOMETRIC

In the Paper, Embedded Voting System using AT89S52 Microcontroller is an interesting project which uses 89S52 microcontroller as its brain. The paper is designed for three contestants. Voters can pull their vote to any one of the contestant. A polling officer switch is provided to avoid multiple polling of a single voter as a reset button. Every voter should get approval from the polling officer, namely the enrollment. If the polling officer issues approval with his control switch which is the identification process, then only a voter can pull his vote. This issuance of approval is indicated by a 16*2 LED display. A switch is provided to count and display the total number of vote's polled and individual contestant-vise votes polled. If this switch is pressed, the polling process cannot continue. A buzzer is provided for audio effect of switch bounce. Whenever a switch is bounced, the system acknowledges the bounce by a short beep sound, like whenever there arises the issue like re-voting and also if the fingerprint is not recognized properly in a correct way. There is primarily a step-down transformer which converts from 230/5V and supply the voltage evenly across the whole board.
