| <h3>Abstract:</h3> | ||
|
|
||
| Online voting is attractive for convenience and accessibility, but is more | ||
| susceptible to voter coercion and vote buying than in-person voting. One | ||
| mitigation is to give voters fake voting credentials that they can yield to a | ||
| coercer. Fake credentials appear identical to real ones, but cast votes that | ||
| are silently omitted from the final tally. An important unanswered question is | ||
| how ordinary voters perceive such a mitigation: whether they could understand | ||
| and use fake credentials, and whether the coercion risks justify the costs of | ||
| mitigation. We present the first systematic study of these questions, involving | ||
| 150 diverse individuals in the U.S. northeast. All participants “registered” | ||
| and “voted” in a mock election: 120 were exposed to coercion resistance via | ||
| fake credentials, the rest forming a control group. Of the 120 participants | ||
| exposed to fake credentials, 96% understood their use. 53% reported that they | ||
| would create fake credentials in a real-world voting scenario, given the | ||
| opportunity. 10% mistakenly voted with a fake credential, however. 22% reported | ||
| either personal experience with or direct knowledge of coercion or vote-buying | ||
| incidents. These latter participants rated the coercion-resistant system | ||
| essentially as trustworthy as in-person voting via hand-marked paper ballots. | ||
| Of the 150 total participants to use the system, 87% successfully created their | ||
| credentials without assistance. Therefore, 83% successfully created and | ||
| properly used their credentials. Participants give a System Usability Scale | ||
| score of 70.4 — 58th percentile across diverse system studies. Our findings | ||
| appear to support the importance of the coercion problem in general, and the | ||
| promise of fake credentials as a possible mitigation, but user error rates | ||
| remain an important usability challenge for future work. | ||
