An electronic voting system called iVote has recently been implemented in New South Wales, Australia, to give those with low vision, blindness or a disability an alternative way to vote. It’s currently only available to those who are unable to vote in person on election day: those people living more than 20 km from a polling place or those travelling outside of the electorate.
Quite surprisingly to me, it would be extremely easy for a foreign power to compromise Estonia's system to hack into the system and either alter the results of an election or, short of that, just cause the election to fail and be discredited.
In my view it's going to be perhaps a decade - if ever - before we're able to secure internet voting against these powerful threats. And for now the absolute safest course of action is not to vote online at all or, at least, to limit as much as possible the number of votes that are cast with online systems.To read more from the ABC News Australia interview, reported by Alice Matthews, go to: http://www.abc.net.au/am/content/2015/s4184471.htm
