National: Voting Machines: A Weak Link | EE Times
In my community, we vote by filling in circles on a paper sheet that goes into a scanner — we have a paper trail. Can such a process still be hacked? Yes, though paperless voting machines can more easily be hacked. Professors Ronald Rivest of MIT and J. Alex Halderman of the University of Michigan explained on Sept. 13 in a session at EmTech MIT on how hackers can alter elections. According to Rivest, about 80% of voting jurisdictions in the U.S. have some sort of paper trail in the event of voting-machine hacks. If, however, you vote in Delaware, Georgia, Louisiana, New Jersey, South Carolina, or Nevada, there is no way to hand-count the votes should the need arise; votes are electronically recorded. The map below reveals that many other states use a mixture of paper and paperless voting systems.
