Design and Implementation of a Secure Electronic Voting System Using Fingerprint Identification and Real-Time SMS Notifications

Abstract

This project presents the design and implementation of an electronic voting system that enhances security, efficiency, and reliability through the integration of several key technologies. The system incorporates an LCD display for user interaction, a fingerprint module for secure voter identification, and a GSM module for sending real-time SMS notifications. The primary objectives are to ensure that only registered voters can cast their votes, prevent multiple voting by the same individual, and provide timely updates on voting results. The hardware setup includes an Arduino microcontroller connected to an LCD display, a fingerprint module, a GSM module, buttons for voter input, a buzzer for feedback, and a shifter for controlling the GSM module’s power state. The software is designed to manage the enrolment of voter fingerprints, validate RFID cards, identify voters, and record votes. Votes can be cast for one of three parties, with the system maintaining and displaying vote counts. Additionally, the system sends periodic updates of the vote counts via SMS. This project achieves significant milestones in securing the voting process through fingerprint recognition, providing user-friendly interaction via the LCD, and ensuring transparency with real-time SMS updates. The system effectively prevents voting fraud by ensuring each voter can vote only once. Future enhancements could include scaling the system to accommodate more voters and candidates, improving error handling, refining the user interface, and integrating with broader voting systems. This electronic voting system demonstrates the practical application of embedded systems and communication technologies to improve election integrity and management.
