Taking inspiration from the security devices issued by some banks, Gurchetan Grewal and colleagues from the University of Birmingham have developed a system that allows people to vote by employing independent hardware devices in conjunction with their personal computers.

"This is currently the only piece of work that addresses a core problem of e-voting - namely, that someone may have viruses or other malware on their computer," noted Grewal, who is part of the project team and recently completed his doctorate in online voting at Birmingham.

The new technique offers a fresh contribution to the debate surrounding e-voting and could be ready for use in time for the 2020 or 2025 general election, the study noted.

"This system works by employing a credit card-sized device similar to those used in online banking," said lead researcher professor Mark Ryan.
