Maryland tested the new Verifiable Voting System designed by David Chaum and his team. I haven’t see logs and comments about that so far, but I believe everything gone fine. Immediately after the news my guess was, why we don’t try the system in a biggest contest like, for example California ? With respect to the current test, I believe that a wider range of people may prove a higher reliability, and much more test cases ( I know that it is a pretty new system but I also know that it has been studied for a while) to stress the system.
These are the two main laws issues :
13204. (a) “All distinguishing marks or erasures are forbidden and
make the ballot void.”
14287. “No voter shall place any mark upon a ballot that will make
that ballot identifiable.”
For people that don’t know how scantegrity works here a nice graphical summary.
As you see in the figure above, people have to mark the ballot (“Waht Voter Leaves in the Ballot Box”) and people could keep a voting proof (A: “What Voter Takes Home”).
