The revised version of Ron Rivest's ThreeBallot[0][1][2] has always felt like a decent, albeit complex, solution to me. It's clear, relatively secure, auditable, verifiable, and somewhat anonymous. For those unfamiliar: > The idea is that you xor together 3 ballots when you vote, but one of the three ballots is published.[3] > The trick to the 3-ballot voting protocol is that not everyone can validate their vote. However, when a group of voters band together, they should be able to validate that a subset of their votes (1/3) were registered with high probability. > ... > With a sufficiently large group of voters checking results, the law of large numbers comes into play and they can statistically detect the presence of voting fraud.[4] You would still need to trust that the poll worker is tabulating correctly and working randomly, though that's an assumption that we're already making as it is. Scantegrity[5], Prêt à Voter[6], Helios[7], and Punchscan[8] also seem promising, though I'm not as familiar with them.
