Abstract

In many end-to-end voting systems there is a single entity that produces each ballot. This entity can be the printer in the case of paper ballots, or the voting machine in the case of an electronic interface. While not able to change election results, this powerful entity has access to confidential information and can reveal selections made by the voters which, along with the voter's identities, can compromise the secrecy of the ballot. We propose ClearVote, a new end-to-end voting system that has no single entity that can reveal ballot selections. The ClearVote ballot has three sheets of transparent plastic, each sheet coming from a different printer. Assuming no two printers collude, there is no single entity with enough knowledge to reveal ballot selections.
