If, like a growing number of people, you’re willing to trust the Internet to safeguard your finances, shepherd your love life, and maybe even steer your car, being able to cast your vote online might seem like a logical, perhaps overdue, step. No more taking time out of your workday to travel to a polling place only to stand in a long line. Instead, as easily as hailing a ride, you could pull out your phone, cast your vote, and go along with your day. Sounds great, right? Absolutely not, says Stanford computer science professor David Dill. In fact, online voting is such a dangerous idea that computer scientists and security experts are nearly unanimous in opposition to it. Dill first got involved in the debate around electronic voting in 2003, when he organized a group of computer scientists to voice concerns over the risks associated with the touchscreen voting machines that many districts considered implementing after the 2000 election. Since then, paperless touchscreen voting machines have all but died out, partly as a result of public awareness campaigns by the Verified Voting Foundation, which Dill founded to help safeguard local, state, and federal elections. But a new front has opened around the prospect of Internet voting, as evidenced by recent ballot initiatives proposed in California and other efforts to push toward online voting. Here, Dill discusses the risks of Internet voting, the challenge of educating an increasingly tech-comfortable public, and why paper is still the best way to cast a vote.
