Parallel Testing

The testing of randomly selected voting machin es during an election. A “process designed to detect the potential presence of malicious code in the software of a voting machine. It requires a specific number of voting machines to be removed from random poll sites before voting begins. These machines are then test-voted throughout election day.” Wash. Admin. Code §434-335-510. This method was proposed by Mich ael Shamos in 2003 to detect systems programmed to behave differently while the polls are open, thus defying pre- and post-election LOGIC AND ACCURACY TESTING.
