Linux On Brazilian Voting Machines, the Video 252

Augusto writes "Just 10 days ago, 130M Brazilian voters were turned into users of one of the largest Linux deployments worldwide: the 400,000 electoral sections in all of the 5,563 Brazilian municipalities were running electronic voting machines, and the Linux kernel was running in all of them. These voting machines have been used in Brazil since 1996, and are rugged, self-contained, low-spec PCs. We've discussed the technical details of this Linux deployment and implementation elsewhere, but I thought it would be interesting to show some pictures (and a movie) of Linux booting on these voting machines. So I asked for official permission and thus was helped by a technician while I took some quick pictures and made a small movie showing the boot process, where you can actually read the kernel messages."

        An election process has to provide the following characteristics (in some countries these are taken serious):

              1. Access: Only people allowed for voting may place their vote
              2. Equality: Each person may only be counted once and with the same weight of vote.
              3. Privacy: Noone can find out for whom a person voted.
              4. Secure against forgery:
                          1. Valid votes can not be changed/forged.
                          2. Valid votes may not be destroyed.
                          3. Invalid votes may not be added
              5. Checkable: Each voter has the possibility, independent from any other person, to check the correctness of an election including all previous points.
        ( I didn't find this in the English Wikipedia, this is a quick translation from the German Wikipedia [wikipedia.org] )**.

        You cannot ensure these with voting machines without the use of paper*. It is not a matter of code, just a fact of information and physics.

        With voting machines, you get a bunch of places where candidates happen to win by a 16384 vote margin -- is that deliberate tampering, machine error, or maybe just plain luck? You'll never know, and therefore you'll probably never catch the criminals.

      My main question is who can modify the source of the software they're using, and how are they verifying that the binaries are unmodified. Generally, I agree that Linux doesn't belong there, but I don't think it's unreasonable to say that any software used in voting machines must be open source.

      Here in the states, state law clearly defines how votes should be cast and counted. Without the source code to the program responsible for counting the votes, these laws will quite literally read something along the lines of:

      1.Voters enter votes into machines.
      2. ???
      3. Voters receive election results.

      The procedures for voting are a matter of public law. That must extend to procedures within the voting machines.

      If you think that's putting too large a technical burden on the lawmakers, look at building codes, patent law, etc. It's a little too late to call for law that is perfectly accessible to non-technical citizens.

      • If you think that's putting too large a technical burden on the lawmakers, look at building codes, patent law, etc.

        Should also note that because voting is mostly a state (non-federal) affair, minimum standards should first be set the federal government.

      If banks can transfer billions of dollars every day safely and securely (in many cases without even a paper trail), there is no reason why a decent electronic voting system can't be made. Compared to an ATM, a voting machine should be a piece of cake, you don't have to worry about verifying the user's identity. You don't need to check the balances and rights. All you need to do is accept and record the current user's vote, them reset for the next user.

      Do give us open source so there are 50,000 coders doing Q&A on it. Do give us a paper trail so that if there is any suspision then the vote can be verified. Do involve election officials in at least the requirements process.

      Don't give us a function that clears all votes made on the system so that polling officers can 'adjust' the vote. Don't give us hardware which uses the same exact key to unlock every case. Most important, Don't try to cover it up if you screw the pooch; let us know so the recount can be performed by hand.

        Wow, that's a pretty terrible non-sequitur. The requirements for banking and voting are completely different. An ATM does not have to make sure that you cannot prove to anybody what you did when you used it. It does not have to prevent other people from tracing any action back to you. And if something goes wrong or someone tampers with the machine, you will know it sooner or later and can complain to your bank.
