IoT Based Voting System with Fingerprint Verification

Abstract

The use of an IoT-based voting system with fingerprint verification ensures that voting is secure and that malpractice is reduced. The voter's information, including their fingerprint, is saved in a database. If the fingerprint matches one in the database, the system checks the user's data and, if they are authenticated, checks for multiple votes. If the fingerprint match is incorrect, the message "Record doesn't exist" will appear. The controller is an Arduino Uno, and the user is authenticated using a fingerprint sensor. When a misbehaviour occurs, the notice "Currently casted a ballot" will appear. The Arduino IDE is used to programme the device, and the cloud is used to display the voting form card and to collect data.
