Electronic Voting's Fundamental Flaws

phil reed writes "Given the latest fiasco in Florida's continuing attempts to implement a decent voting system, I thought it would be appropriate to alert Slashdot readers to the work of Dr. Rebecca Mercuri. She's been studying voting systems for many years, and has developed well-considered positions on what makes a good electronic voting system (and what makes a bad one). Her comments on the Florida 2002 election can be found in the current Risks Digest. And, if you think that creating a computer-based voting system is easy, she provides a suggested list of questions that should be answered by any developer." Mercuri's statement in Risks is well worth reading. With all due respect, she is wrong in some respects: it is possible to create a fully-verified electronic system. Start with completely open code and thoroughly examined hardware, create an audited system for installing the code on the hardware, and make it tamper-evident so that you know the same code is still there when the machine reaches the voting booths. Bootable, hologrammed, serial-numbered CD-ROMs with individual private keys would do the trick. Mercuri is thinking in terms of vendors selling proprietary "solutions", where she's absolutely right: there's no way to verify that what people punch in is what is actually recorded.

      • we voted every few days on some micro-issues like what the tax on gas should be for the coming month

      Of course it isn't, but the idea is that it might actually be viable to prevent fraud with electronic voting... although I suspect that, as geeks, we can't poke as many holes in an electronic system as you can in a paper system.

      With proper security, however, the bar gets raised a lot higher.

      I think the best system is still a card system

      Well, perhaps... except that even with arrow systems you wind up with cards that are invalid because someone mismarked them, didn't mark hard enough, the graphite wears off with enough recounts, etc. And even with these systems the recounts never produce the same numbers, and they take a considerable amount of time.

      Electronic systems have the potential of eliminating all of these issues (note trolls - I said potential, not absolute). The system will prevent you from entering a ballot that is invalid. You won't accidentilly vote for two different candidates in the same race - just not possible. And barring fraud (see above), the vote won't be questionable, it won't decay with recounts, and the recount will be nearly instantaneous (depending on how long system verification takes) and will add up the same every time (if it doesn't, you're in the land of fraud again).

      Eventually we might be able to do online voting, which would be pretty nice if done properly (big if). Sure as hell won't get that with a paper ballot. Of course, 80% of the reason to go to Internet voting could be solved just by getting into the 20th Century (yes, 20th) and allowing voting for more than 12 hours on a single workday. Come on -- week long voting shouldn't be an issue. If it's a cost problem, then a Saturday would still be better than Tuesday.

      Hear, hear. Paper and ink has huge advantages when it comes to ballots. Everyone can see exactly who they voted for, the votes can be recounted at will and, maybe most importantly, we know how to secure and audit the management of lockboxes of paper votes. Been doing it for a long time.

      The one downside of hand-marked paper ballots is that they're hard to count electronically. If electronic counting is important, I think a hybrid system is the way to go: use a nice, easy-to-use touch screen to make your selections and then have a printer mark your votes on the paper ballot in both human and machine-readable formats. Then, at tally time, you can rapidly and accurately generate a file containing all of the numbered ballots (grouped by voting district) and the votes cast. This file can then be published and anyone who wants to can tally up the votes for themselves.

      Further, you can take a random sample of the paper ballots and manually verify that the human-readable portion, the computer-readable portion and the tally file's summary of this ballot are all in perfect agreement. A relatively small sample can provide an extremely high level of confidence that the system is functioning correctly.

      With this kind of method, there is no question about the correctness of the software, whether open or closed, because if it prints the wrong selections on the human-readable portion, the voter will catch it. If it prints the wrong selections in the computer-only portion or if the counting system makes errors, the random verification will catch it. If there are errors, you can always fall back on purely manual counting.

      Electronic ballot-counting does have some advantages over manual counting: it's cheaper, faster, apolitical and the notion of a published "tally file" makes it more open and more widely verifiable.

      But, given a choice between a purely paper-based system and a purely electronic system, I'll take paper. And I'll take just about anything over those punched cards.

    Briefly, Jones disassembled an example of the votomatic machines in question. He found that there was a structural bar behind the slots through which the chads were to be poked. Jones's investigation proved that candidates whose holes were to be punched over those bars were practically guaranteed to jam. Whoever designed the ballots laid them out so Gore's chads were directly over that bar.

If you were going to implement such a system, wouldn't you try it out or test it in a wide scale first?

    Dade and Broward counties, where most of the problems occurred, are also two of the most populated counties in Florida with the highest numbers of elderly and poor people. Imagine implementing a whole new voting system without doing a wide scale dry run. The kind of massive problems that we witnessed here where to be expected. What also wasn't addressed where the kind of organizational details like having enough poll workers of both political parties at each polling place. That meant that some polling places could not open. We still had the usual record keeping problems, registered voters not appearing in the voter rolls and poorly trained poll workers.

They didn't even have a good way to communicate to all polling places to stay open an extra 2 hours.

What kind of moron would take brand new untested technology and put it out to be managed by poorly trained technophobes and expect less that a complete disaster?

    Before you start giving the poll workers a hard time consider the fact that they had to be at the polling place by 6:00 AM and that they would have to stay till poll closing time. There is only one set of people working the polling sites. There is no second watch. You go home after the polls close. After the last person votes you get to break down the machines and collect the votes and so forth. So conservatively, if the polling window is not extended like it was, the earliest you'd get out would be 8:00 PM. Thats 14 hours minimum. Then you add an extra 2 hours and you have to stay around till 10:00 PM. All this and you only had lunch around noon sometime. By 11:00 PM some of these old folks must have been hypoglycemic!

Their main purpose in life seems to be making other "more progressive" states like Alabama, Arkansas and Mississippi look good in comparison. The only thing more screwed up than our voting systems is our child foster care system, which is also managed and organized by the same group of geniuses in Tallahassee.

Even if the code and hardware (if one can examine the microcode) appears to be entirely pristine, Ken Thompson explained in his classic 1984 essay "Reflections on Trusting Trust" (available online, do a Google search) that the compiler that compiled all of that code can be rigged such that malicious code can be concealed. For example: Since the dates of US National Elections are fixed to infinity (they are always the 1st Tuesday in November) and since many voting systems (as well as computer systems) rely on real-time clocks, it is certainly plausible to create a hardware trap that only goes off on election day. And that trap doesn't have to be in the voting system either, there's tallying devices, reporting software, and so on. It's a nightmare. The only sane solution is to rely on a voter-verified physical audit trail that can be READ BY HUMANS in case of the necessity for a recount.
