Voting systems designed to be tamper-resistant may be missing lots of votes. New research shows that only 58 percent of ballots using new end-to-end technology were successfully cast. The systems are designed to give voters the option to both verify the system is working properly and to check that their votes have been recorded after leaving the polling place. Voting concerns such as accuracy, privacy, and bribery/coercion have prompted research and development of ways to make voting tamper-resistant and verifiable by voters. While the three systems evaluated solved many of the security problems surrounding voting with traditional methods—such as voters being able to independently confirm that a vote was counted correctly—the systems’ added complexity appeared to negatively impact their usability. “Overall, the tested systems were exceptionally difficult to use,” says Claudia Acemyan, a postdoctoral fellow at Rice University and lead author of the study that is published online in the Journal of Election Technology and Systems.
