Electronic voting is clearly here to stay, but it's been plagued with accusations of fraud and insecurity at nearly every election since it was introduced. But voting systems designer David Bismark may have a solution.
His new system, which he described in a talk at TEDGlobal 2010, uses multiple steps to ensure security and make tampering next to impossible.
In his system, everyone gets a ballot with an encrypted barcode on it. On one side of the ballot is the list of candidates in a random order, and on the other are the checkboxes. When you vote, you rip it in half and keep the ordered list of candidates and turn in the half with the checkboxes and your barcode. You turn in that half and election workers scan it into the system.
You can then take your half home and verify your votes online. And once the election is complete, the votes are decrypted in several steps, spread among different organisations, and the plain-text, countable votes can then be tallied.
This system makes it impossible for any one person or group to tamper with votes, instead requiring all of them to work together, something very improbable. It makes a lot of sense! Whether or not something that makes so much sense will actually be implemented, well, we'll have to wait and see. [Bismark.se via Wired.co.uk]
