Enhancing Electoral Integrity: A Fingerprint-Verified Voting System for Fair and Secure Elections

Abstract

Voting is a significant method through which citizens in democratic nations like India can express their opinions. Voters often use polling booths to cast their ballots. Voting is now done via an electronic voting machine thanks to advancements in technology. This essay discusses a fingerprint-verified voting machine that is Internet of Things based. The primary goals of this project are to decrease voting malpractices and make voting safer with fingerprint verification. Voter information is kept in a database along with their fingerprint. The system verifies the user's Aadhaar number and, if verified, determines whether more than one vote has been cast if the fingerprint matches the stored fingerprint. A "Matching failed" message will appear if the fingerprint matching is incorrect, and an "Aadhar not match" message will appear if the Aadhaar number is incorrect. The controller used in this project is an Arduino Uno. The user's fingerprint is used for authentication. Everybody's fingerprints differ from one another, if not slightly. A notification stating "Already voted" will appear in the event of malpractice. The ballot card is displayed and the result is stored on the cloud using the Arduino IDE for board programming. Only authorized voters may cast ballots, and the system alerts users to instances of fraud. This project ensures fair elections and protects citizens' right to vote.
