I am a computer scientist and have been working on voting integrity issues for well over a decade, including co-authoring Broken Ballots, a book on voting technology.  While I am also a member of the Board of Advisors of the U.S. Election Assistance Commission, I am speaking for myself only and not on behalf of any organization with which I am associated.

Given the prevalence of software bugs and the risk of hidden malware, there is no way to verify that the results produced by a paperless voting machine are correct.  Furthermore, we have known for some time that the WinVote machines are especially insecure and unreliable, as Jeremy Epstein documents in his excellent posting.  Therefore, I urge the Board of Elections to replace the WinVote machines with a more modern paper-based voting system that also allows for recounts and post-election ballot audits.
