Follow up to previous postings on e-voting, via Wired: “On Tuesday voters in Takoma Park, Maryland, got to try out a new, transparent voting system that lets voters go online to verify that their ballots got counted in the final tally. The system also lets anyone independently audit election results to verify the votes went to the correct candidates. The open source, optical-scan system, called Scantegrity, was developed by cryptographer David Chaum, with researchers from MIT, the University of Maryland in Baltimore, George Washington University, the University of Ottawa and the University of Waterloo…Although the system is highly technical, the experience for voters is the same as with any other optical-scan system. Voters make their selections on a paper ballot using special pens with ink designed by Chaum. When a voter fills in an oval on the ballot, the ink in the pen, which is similar to the yellow ink in highlighter pens, reacts with invisible ink in the oval and turns most of the oval black. At the same time, a unique three-letter code pre-printed on the ballot inside each oval is revealed to the voter.”
