Securing Digital Elections: A Lightweight Model Integrating Blockchain and Multifactor Authentication for Mobile Compuing

Abstract

Traditional voting systems face significant challenges in transparency, security, and trust, compromising their credibility and effectiveness. To address these issues, this study proposes a lightweight voting system that integrates blockchain technology with a simplified Multifactor Authentication (MFA) model, relying solely on voter ID verification and One-Time Password (OTP) mechanisms. By leveraging blockchain's decentralized and immutable ledger, the system ensures secure, tamper-proof recording of votes while maintaining transparency. The lightweight authentication approach balances security and efficiency, with voter ID verifying eligibility and OTP adding a real-time layer of authentication without the need for additional hardware or complex biometrics. Smart contracts automate voting operations, providing auditable results while reducing reliance on intermediaries. This streamlined integration significantly improved accuracy by 25%, reduced processing times by 30%, and strengthened voter trust by 40% compared to traditional systems. The proposed solution demonstrates a practical, scalable framework for secure and transparent voting, with potential applications in corporate governance, online referenda, and decentralized autonomous organizations (DAOs).
