Managing Secure Elections: Fingerprint Authenticated Voting System Design

Abstract

This study presents the design and development of a fingerprint-authenticated voting system aimed at ensuring a robust and secure election process. The proposed system integrates hardware components such as a microcontroller, fingerprint sensor, push-button switches, and an LCD display to facilitate efficient voter authentication and vote casting. An R350 fingerprint sensor is employed to capture and store voters’ fingerprint data in its internal memory. These biometric inputs are subsequently processed and verified using an integrated controller to ensure accurate identification. The human-machine interface (HMI) is implemented through a 16×2 LCD module, which provides real-time instructions and system status to the user, enhancing usability and interaction. Once authenticated, the voter is allowed to cast their vote through a simple interface, ensuring both security and ease of operation. The system effectively minimizes electoral fraud, such as duplicate voting and impersonation, by leveraging biometric verification. Overall, the proposed design offers a cost-effective, reliable, and user-friendly solution for secure electronic voting, making it suitable for deployment in modern electoral systems.
