Temper proof data distribution for universal verifiability and accuracy in electoral process using blockchain

Abstract

In this article, a secure and verifiable electronic voting scheme is proposed. Encrypted votes are accumulated and prepared in the form of block on each electronic polling booth at the end of polling time. The resultant block from each electronic polling booth is distributed to the authorized nodes of group for temper proof block chaining that assures the internal verifiability. The external verifiability is attained through the redistribution of temper proof Blockchain ledger to the validated and authorized nodes of auditing group. The temper proof property of electoral data is achieved using an emerging Blockchain Technology. Whereas the secure data distribution in the form of temper proof blocks and ledger amongst the authenticated group members is accomplished through the cryptographically secure group oriented scenario. The individual and universal verifiability features in our proposed scheme make the electoral process transparent, reliable and verifiable.
