I wrote this paper with Arthur Keller, Alan Dechert, and Karl Auerbach.
This paper details design principles of the Open Voting Consortium voting
system. We contrast our design with other voting technologies, with my
contribution being in the analysis of the need for a paper ballot, in contrast
with a paper "receipt" or mere "paper trail". I also critique Rebecca
Mercuri's "ballot-under-glass" design as adding complications and security
threats while actually failing to provide as much integrity assurance as OVC's
physically inspectible ballot.
