There are a lot of comments here, but for anyone who’s looking for a well thought out implementation of publicly verifiable ballots, I suggest taking a look at Scantegrity [1]. Gotta love all the brilliant minds who worked (and implemented in the US!) it (David Chaum, Richard Carback, Jeremy Clark, Aleksander Essex, Stefan Popoveniuc, Ronald L. Rivest, Peter Y. A. Ryan, Emily Shen, and Alan T. Sherman) [1]: http://scantegrity.com/papers/ScantegrityII-EVT.pdf http://scantegrity.com/papers/ScantegrityII-EVT.pdf Note: They published several papers on the implementation and design of the Scantegrity system. I just linked to one of them (the most recent I believe).
