An On-Site Electronic Voting System Using Blockchain and Biometrics

Abstract

Electronic voting (e-voting) improves the convenience of voting and the efficiency of vote counting. With the rise of blockchain technology, many studies have proposed e-voting systems using blockchain technology. Most of them consider the usage scenario of remote voting and pay less attention to that of voting conducted at polling stations. In view of this research gap, this study proposed a blockchain-based system for e-voting at polling stations. We designed a system process integrating blockchain technology and voter’s biometrics to prevent data tampering and imposter voting. In addition, the blockchain platform adopted in our proposed system is Hyperledger Fabric (HF). Therefore, based on the HF framework, we specified how to deploy a blockchain network customized for this study. Finally, this study provided a property analysis of the proposed system and implemented a simulation system. In conclusion, the proposed system meets the requirements e-voting from two aspects. First, in terms of technology, our system adopted blockchain, digital signature, and biometric identification to achieve eligibility and immutability. Second, in terms of system process, the roles of government agencies and inspectors are incorporated to achieve transparency, receipt-freeness and accessibility
