A practical voting scheme with receipts

Abstract

David Chaum introduced Visual Voting scheme in which a voter obtains a paper receipt from a voting machine. This receipt can be used to verify that his vote was counted in the final tally, but cannot be used for vote selling. The Chaum's system requires sophisticated printers and application of randomized partial checking (RPC) method. We propose a complete design of a voting system that preserves advantages of the Chaum's scheme, but eliminates the use of special printers and RPC. © Springer-Verlag Berlin Heidelberg 2005.
