David Bismark has co-developed an electronic voting system that contains a simple and reliable method of verification.

Why you should listen

One of the main objections to e-voting is that it's difficult for each voter to know that her vote was recorded accurately and counted correctly, while she remains anonymous. In the system designed by David Bismark and his colleagues, each voter gets a takeaway slip that serves as a record of the vote, and allows elections to be independently verified.

Apart from his work on voting systems, Bismark runs Recito Förlag, a publishing company in Sweden.
