Fingerprint-Authenticated Blockchain E-Voting: A Secure Digital Election Framework

The increasing need for secure, transparent, and tamper-proof election systems has led to the integration of biometric authentication and blockchain technology in e-voting systems. Traditional voting methods suffer from issues such as fraud, manipulation, and lack of transparency. This proposed e-voting system leverages blockchain’s decentralized and immutable ledger to ensure data integrity and security, while biometric authentication, specifically fingerprint recognition, prevents voter impersonation and ensures eligibility. The system stores encrypted votes on a blockchain, ensuring that records remain secure, transparent, and resistant to tampering. Smart contracts facilitate vote validation and counting, reducing human intervention and potential bias. By combining biometrics with blockchain, the system enhances security, trust, and accessibility, enabling a more efficient and fraud-resistant voting process. Simulation results confirm its effectiveness in ensuring anonymity, integrity, and real-time verification, making it a viable solution for modern democratic elections.
