Abstract

Pret a Voter and Punchscan are two electronic voting schemes that both use paper based ballot forms, part of which is detached and destroyed, to provide receipt-free voter verifiability. However, both schemes share the chain voting problem and the part destruction problem. The first is where anyone who can see the ballot form before it is used can coerce a voter who uses it and the latter where a voter who can leave with the complete form can prove to a coercer the contents of the vote. In this paper we provide a comparison of the schemes from a systems perspective. We also introduce a visual encryption solution to both the above problems.
