Voting security and technology

Voting seems like the perfect application for technology, but actually applying it is harder than it first appears. To ensure that voters can vote honestly, they need anonymity, which requires a secret ballot. Through the centuries, different civilizations have done their best with the available technologies. Stones and pottery shards dropped in Greek vases led to paper ballots dropped in sealed boxes. Mechanical voting booths and punch cards replaced paper ballots for faster counting. Now, new computerized voting machines promise even more efficiency, and remote Internet voting promises even more convenience.
