"Ten years ago, the replacement of pencils and ballot papers by machines was seen as a badge of modernity. But technology was not sufficiently advanced to guarantee security of the new system."
I disagree with this assertion. I think the technology is /too/ advanced to guarantee security of the system. I'm reminded of Clarke's 3rd law: "Any sufficiently advanced technology is indistinguishable from magic." We cannot have a trusted system of democracy if voting works by magic. Voting needs to work in a way that everyone can fully understand.
