Secure Online Voting System Using Blockchain

Abstract

In large democracy like India with about 83.4 crore voters it is estimated that about 50,000 crore rupees is spent on election and it takes about 6 weeks to conduct election. So the approach of election followed in India is costly both in terms of time and money. In order to reduce the cost of time and money, in last few decades numerous methods have already been developed and one of them is to use online voting system that providers the comfort of voting from remote location. But traditional online system has its own drawbacks like data tampering, privacy breach, etc. Blockchain technology is proposed, that incorporates cryptographic properties. Blockchain technology is simply defined as a decentralized, distributed ledger that maintains the provenance of a digital asset and is considered to be utmost secure. To avoid single point of failure, two step authentication process is used which include OTP verification and Biometric authentication. To ensure the anonymity of the votes, Identity-based ring signature scheme is used.
