–in Selene: Voting with Transparent Verifiability and Coercion-Mitigation (Peter Y.A. Ryan, Peter B. Rønne, Vincenzo Iovino)
“We take a different approach and revisit an old idea: to provide each voter with a private tracking number. […] This is appealing in that it
provides voters with a very simple, intuitive way to verify their vote, in the clear.”

–Donald Norman
“Mental models are people’s view of the world, of themselves, of their own capabilities, and of the tasks that they are asked to perform, or
topics they are asked to learn.”

What have we learned?
12
• People care about Privacy and Coercion
• Verification is confusing
• Trust important for security perception
• Accessibility of knowledge
Impact on Voting Research
• 1 hour to understand
• Incomplete experience
Limitations
• 100% of effectiveness
• A lack of understanding
• Security unseen
