About the Voting Technology Project

Established by Caltech President David Baltimore and MIT President Charles Vest in December 2000 to prevent a recurrence of the problems that threatened the 2000 U.S. Presidential Election. Since establishment, members of the VTP have studied all aspects of the election process, both in the United States and abroad. VTP faculty, research affiliates, and students have written many working papers, published scores of academic articles and books, and worked on a great array of specific projects.

This note is a response to, and critique of, recent work by Acemyan, Kortum, Bryne, and Wallach regarding the usability of end-to-end verifiable voting systems, and in particular, to their analysis of the usability of the Scantegrity II voting system. Their work is given in a JETS paper [Ace14] and was presented at EVT/WOTE 2014; it was also described in an associated press release [Rut14]. We find that their study lacked an appropriate control voting system with which to compare effectiveness, and thus their conclusions regarding Scantegrity II are unsupported by the evidence they present. Furthermore, their conclusions are contradicted by the successful deployment experiences of Scantegrity II at Takoma Park.
