Blockchain Based Secure Voting System

Abstract

Due to the ever-increasing demand to use safe and reliable electronic votes, a blockchain-based secure voting system has been developed to enhance transparency, trustfulness, and voter recognition.  This system eliminates such issues as voting fraud, impersonation, and manipulating the results by means of biometric verification and decentralized blockchain ledger.  The voters are matched to a facial-recognition database containing previously registered voters before voting.  It is authenticated by a K-Nearest Neighbors (KNN) approach as it works well on classifying facial features and is not very laborious.  After the vote is successfully authenticated, it is stored and signed on a blockchain network where it cannot be altered by another party.  The features of smart contracts ensure the safety of voting, the correct counting of votes, and the awareness of each network node of what is happening.  The cryptography of hashing and decentralized make certain that the votes are immutable, due to the decentralized structure of blockchain and consensus mechanisms. The face-matching module ensures that only the qualified individuals are allowed to vote.  The system also supports mass elections and guarantees the ease of interaction among the voters. It was designed in such a way that it is scalable and user friendly.  Trust, security, and efficiency are enhanced in the system through biometrical authentication, distributed ledger technology, encryption, and classification through machine-learning. It is highly dependable in how to conduct the current digital elections.
