A study of ballot anomaly detection with a transparent voting machine

Gilbert et al said that many components contribute to a safe and secure election, but several experts agree that the most important one is to include risk-limiting audits on voter-verified paper ballots. Ballot-marking devices (BMDs) allow voters to select candidates on a machine and print a physical ballot summary that can be tallied and used for a later audit. The paper ballots must be voter-verified before being cast to ensure that if their vote has been tampered with, or if they have made an error, it can be rectified. The voter, after all, is the only one who knows their intention and whom they meant to vote for. The fundamental idea of the transparent voting machine is to enable users to vote on an accessible BMD and view their printed ballot at the same time. The touchscreen interface of the BMD is transparent and located above where the ballot summary is printed.
