Blockchain and Internet of Things (IoT) Enabled Smart E-Voting System

In the present situation, most people are not satisfied with the final result of the voting system. This is because the current system for voting is centralized and fully controlled by the election commission. So, there is a chance that the central body can be compromised or hacked and the final result can be tempered. In this direction, a decentralized, Blockchain and IoT based methodology for voting system is devised and presented in this paper. Blockchain is totally transparent, secured and immutable technique because it uses concept like encryption, decryption, hash function, consensus and Merkle tree etc. which make Blockchain Technology an appropriate platform for storing and sharing the data in a secured and anonymous manner. IoT makes use of biometric sensors using which people can cast their votes in not only physical mode but also in digital mode. As a response, a message is received to the owner for casting his vote to ensure the authentication. In this way, the present voting system is more secure and trust-worthy by using the properties of both Blockchain and IoT, and therefore, election process in the democratic countries is valued more. The proposed method ensures security as well as reduces the computational time as compared to the existing approaches.
