A push to allow Internet voting in elections is growing stronger along with advances in the underlying technology, but systems are not yet secure enough to use with relative certainty that the vote counts will be accurate, according to a new report. Still, while “no existing system guarantees voter privacy or the correct election outcomes,” election officials could take several steps to significantly improve the security and transparency of Internet voting systems, said the report, commissioned by the U.S. Vote Foundation, an organization that helps U.S. residents vote. Election officials considering Internet voting must embrace an end-to-end verifiable Internet voting system, or E2E-VIV, said the report, released Friday. An E2E-VIV would be difficult to build, but it would allow voters to check that the system recorded their votes correctly, to check that it included their votes in the final tally and to double-check the announced outcome of the election, the report said. An Internet voting system must be transparent, useable and secure, said the report, echoing some recommendations security groups have made about other electronic voting systems. “An Internet voting system must guarantee the integrity of election data and keep voters’ personal information safe,” the report said. “The system must resist large-scale coordinated attacks, both on its own infrastructure and on individual voters’ computers. It must also guarantee vote privacy and allow only eligible voters to vote.”
