"Diebold GEMS central tabulator contains a stunning security hole"
By entering a 2-digit code in a hidden location, a second set of votes is created. This set of votes can be changed, so that it no longer matches the correct votes. The voting system will then read the totals from the bogus vote set. It takes only seconds to change the votes, and to date not a single location in the U.S. has implemented security measures to fully mitigate the risks.
Whether you vote absentee, on touch-screens, or on paper ballot (fill in the bubble) optical scan machines, all votes are ultimately brought to the "mother ship," the central tabulator at the county which adds them all up and creates the results report. The central tabulator is far more vulnerable than the touch screen terminals. Think about it: If you were going to tamper with an election, would you rather tamper with 4,500 individual voting machines, or with just one machine, the central tabulator which receives votes from all the machines? Of course, the central tabulator is the most desirable target.
Findings: The GEMS central tabulator program is incorrectly designed and highly vulnerable to fraud. Election results can be changed in a matter of seconds. [added emphasis]
What I don't understand is how anyone can argue against a paper trail or tighter electronic security. Yes, some people think this is a vast conspiracy to ensure a Republican vote, but let's try to be reasonable. Why would anyone oppose these protections?
