The need for audit-capable E-voting systems

In order for an election system to be trusted, it needs to be verifiable. Methods must exist to check that the votes are cast as intended by the voters. There must be strong evidence that the machines function as they are supposed to function. Voters should feel confident that the election is conducted fairly and accurately. This paper first outlines the major concerns about election technologies. It then describes the existing technologies used in emergent election systems and discusses the potential election audit processes. We then describe four systems used in research: Helios, Scantegrity II, Prêt à Voter and the WAVE systems. Finally, we discuss our recommendations and intended future work
