An anonymous distributed electronic voting system using Zerocoin

Abstract

Existing e-voting systems rely on a database managed by an administrator, and hence the administrator may possibly counterfeits a vote. To solve this problem, there have been proposed utilization of Bitcoin, which we can use as a public database. However, the Bitcoin system has pseudonymity and does not have anonymity that is needed in systems like e-voting. We propose utilization of Zerocoin that gives anonymity to Bitcoin. In addition, our system fixes the group of voters before the voting, and our system makes an administrator’s fraudulent voting difficult.
