The Computer Security Group at the University of California Santa Barbara (UCSB) has released a short, chilling video demonstrating how a single person can hack an election on a touch-screen voting system -- even one with a so-called "Voter Verifiable Paper Trail" (VVPAT) added to it -- in such a way that it is highly unlikely that the manipulation would ever be detected by either the public or election officials.
The video, which shows "just examples of the different ways in which the system can be compromised" is the latest in a similar string of such demonstrations that have been released over the last two years, all showing how easily electronic voting systems can be tampered with, often undetectably.
