    CAPTCHA-based Code Voting
    (Electronic Voting 2008 (EVOTE08). 3rd International Conference on Electronic Voting 2008, Co-organized by Council of Europe, Gesellschaft für Informatik and EVoting.CC, 2008) Oppliger, Rolf; Schwenk, Jörg; Löhr, Christoph
    Code voting provides an appropriate technology to address the secure platform problem of remote Internet voting, but it is not particularly user-friendly. In this paper, we propose the use of CAPTCHA- an acronym standing for Completely Automated Public Turing tests to tell Computers and Humans Apart - to improve the user-friendliness of code voting, discuss the security of CAPTCHA- based code voting, and elaborate on a possible implementation.

    Protecting Code Voting Against Vote Selling
    (SICHERHEIT 2008 – Sicherheit, Schutz und Zuverlässigkeit. Beiträge der 4. Jahrestagung des Fachbereichs Sicherheit der Gesellschaft für Informatik e.V. (GI), 2008) Oppliger, Rolf; Schwenk, Jörg; Helbach, Jörg
    Code voting is an appropriate technology to address the secure platform problem of remote Internet voting. In this paper, we elaborate on the susceptibility of code voting to vote selling, argue that the situation is comparable to all-postal voting, and overview and put up for discussion some organizational and procedural protection measures—recast ballots, multiple code sheets, and powerful voting credentials. The measures are to sap the incentive to sell (or buy) votes and hence to protect code voting against vote selling. We also argue in favor of a clear separation of voter authorization and vote casting and discuss possibilities to do so.
