Protecting Code Voting Against Vote Selling

Abstract

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.
