Traditional voting systems suffer from several challenges, including voter impersonation, ballot tampering, multiple voting, and lack of transparency, which compromise electoral integrity. To address these issues, this paper proposes a Blockchain-Based Biometric Voting System that integrates fingerprint authentication with blockchain technology to enhance the security, transparency, and reliability of elections. Biometric authentication ensures that only registered voters and administrators can access the system, eliminating impersonation and fraudulent voting. The R307 fingerprint module is used for real-time voter authentication, preventing unauthorized access. Once verified, votes are recorded on a blockchain ledger, ensuring data immutability and decentralization. Unlike conventional databases, blockchain technology eliminates single points of failure, preventing vote manipulation and unauthorized modifications. The system also incorporates a web-based interface that allows voters to register, authenticate, and securely cast their votes, while administrators can manage the election process with full transparency. Blockchain’s decentralized nature ensures that all transactions, including candidate registration, vote counting, and election results, are securely stored and verifiable, preventing tampering and external interference. Initial testing demonstrates high accuracy in biometric verification and efficient blockchain-based vote storage, making the system scalable for local, state, and national elections. By integrating biometric security with blockchain’s trustless nature, this system provides a fraud-resistant, transparent, and tamper-proof voting solution, fostering greater public confidence in electoral processes.
