Blockchain and SDN-IoT based secured voting system

Voting is a democratic rights of every citizen of a democratic country. In recent years, voting techniques such as paper ballot, postal ballot, etc., were used to collect votes from the people. These techniques have many drawbacks as the chances of getting invalid votes are much higher, and are less secured and time-consuming. Researchers have also introduced a new blockchain-based e-voting system in order to tackle these issues. This technique has the potential to solve most of the issues of a traditional voting system by enhancing the security, transparency and trust and reduced the chances of fraudulent votes. This method solved the security and reliability of the voting system technologically. However, the prevention of coerced votes from the people is still a major issue, which cannot be handled from a technical point of view. In this paper, a voting system is proposed which can address this issue by using booth voting system along with the convergence of various technologies like blockchain and SDN-IoT platforms. Each voting booth would be considered as an IoT node to collect votes which is controlled by the controller of the SDN. The voting records of the voters are stored on the blockchain. The Voting booth would be protected by the physical security to prevent forced votes. By this technique, the chances of getting untrusted votes from the voters are greatly reduced.
