| They ALL have a known vulnerability. Works like this: Pretend the machine is a person in a secure room only they are in, and only they know the contents of. You approach a window, tell them your vote. They say it back and optionally hand you a piece of paper. Then, in that room, they do whatever they want, and the final tally, winner of the election is determined by whatever they did in the room. Voters have no chain of trust between their expression of intent, and the record used for the final tally. When voters make physical expressions, and those expressions are counted, voters know the election, on a basic level, can be trusted to reflect the collective intent of the people. When they use electronics, they have no idea. They push a button, or mash a screen, and the display will tell them something and that something could be anything. They cannot know. None of us can without forensic level examination of the machine. Even then, we can only verify function and infer a voter intent was correctly recorded and or used for the tally. Secondly, should there be error, or controversy, the enduring record of voter intent both walked out of the building and or is a collection of grease smears on input devices. Useless in a court of law. The only way around this is to make vote records personally identifiable and basically use the systems for banking. (Who gets around this problem with multiple, redundant records created at the time of transaction) |
Or just abandon electronic voting entirely. Ireland tried electronic voting, but scrapped it for just these reasons. You could even keep the ballots in a machine-readable format for sanity checks if necessary.
