E-Voting System Using Blockchain and Homomorphic Encryption

Abstract

Only about half of the elections are deemed to be free and fair, according to a study. Electoral fraud not just mutilates the nature of portrayal, but also has an impact on political, social, and monetary outcomes. Homomorphic encryption and blockchain technologies can be utilized to secure free and fair elections. In this paper, we aim to allow only the eligible citizens to vote by automatically checking their eligibility status from a federally approved application and then securing the voter’s data using homomorphic encryption rather than encrypting the vote cast by the voter. By doing this, statistical analysis can be performed on the data which results in a unique set of insights that may otherwise remain unknown. We have developed a system using the ganache as the local blockchain and the voter data and vote cast is stored in the blockchain.
