You can't let people look up their vote or their employers, spouse, etc, could force them to vote for preferred candidates. Ron Rivest has a system to make it verifiable and deniable (Three ballot system). There are others.
- dandelany 16y agoRivest has the right idea in terms of thinking about this cryptographically... But the Three Ballot system would be an absolute mess :-P Remember hanging chads? Try telling people that to vote against a candidate, they have to mark them on one of three ballots...
- arghnoname 16y agoUsability is a big problem with election systems. Making something anonymous, auditable, fraud resistant, affordable, etc and simultaneously make it usable more or less by everyone is tough. They recently used a system called Scantegrity in Takoma Park, MD (Rivest also collaborated here). I've been meaning to look up the usability conclusions on this one, but I don't remember seeing much in the way of problems at the time.
