MY USA TODAY COLUMN: Paper ballots are hack-proof. It’s time to bring them back. “In some ways, paper and ink is a super technology. When you cast a vote on a voting machine, all that’s recorded is who you voted for. But a paper ballot captures lots of other information: Ink color, handwriting, etc. If you have access to a voting machine that’s connected to the Internet, you can change all the votes at once. To change a bunch of paper ballots takes physical access, and unless you’re very careful the changed ballots will show evidence of tampering. Paper ballots aren’t fraud-proof, of course, as a century of Chicago politics demonstrates, but they’re beyond the reach of some guy sitting at a computer in a basement halfway around the world. And there are well-known steps to make Chicago-style fraud harder.”
