Iowa: Caucus Voting App Stirs Security Concerns | Alexa Corse/Wall Street Journal
Democrats will record the votes from the Iowa presidential caucuses in just over a week using a smartphone app, a procedure that has stirred questions about security. Party leaders said that the mobile app would make it easier and faster to report results from some 1,700 caucus sites. But critics expressed concern about the reliability of the app amid warnings that cyber adversaries could seek to disrupt the 2020 elections. Douglas Jones, an associate professor of computer science at the University of Iowa, who has studied election security, called the idea a “security nightmare,” and said that cellphones were difficult to protect against the range of possible threats. The caucus workers will use the app on their personal smartphones, which Mr. Jones said could be vulnerable, depending on how well the workers take care of their devices.
