Conference Discussion Topic: Ballot Marking Devices Cannot Assure the Will of the Voters
Two competing election systems purport to be auditable and software independent: hand-marked paper ballots and paper ballots printed by machines called Ballot Marking Devices (BMDs). In this talk, I will discuss recent work with Andrew Appel and Philip Stark, arguing that BMDs are neither software independent nor meaningfully auditable by Risk Limiting Audits (RLAs). We also introduce two new conditions called contestability and defensibility that are necessary for an audit to confirm election results.
