This paper proposes a voting scheme that protects voters privacy even when the Central Tabulating Facility reveals individual responses. The basic idea is to add random noise to the true opinion by randomizing in a way such that the true vote is chosen with higher probability than the other alternatives. A major part of this paper is to outline the statistical propeties of our proposed protocol. A commitment protocol is also proposed to cope with dishonest voters who do not randomize their votes. The primary result is that the accuracy of the voting result improves as the number of voters increases.
