Tyler Hamilton reports on electronic voting systems including David Chaum’s SureVote.
Under Chaum’s system, a person selects candidates on a touch-screen terminal and presses “finish” when complete. The machine prints out an anonymous receipt on a double-layer of translucent plastic, which displays the names of candidates the voter selected. If the receipt appears accurate, the voter peels the two layers of plastic apart, and in doing so, the text printed on top of the receipt disappears. This keeps the vote secret.
