Comment on Transportation Hack 2.0: Flaw Found Calif.'s FasTrak Systemparent

Comments

They already take photos of, at the very least, those who slip through without paying or with a missing/faulty/dead transponder.

So step one is just to take a sample: for X thousand FasTrak transactions, for how many did the license plate and transponder disagree? If it's trivial, there's no economic rationale for fixing the system. Just make a note that transponder logs have a Y% fraud/error rate, for when disputes arise.

If still concerned about the other aspects, save the photo log for exactly as long as the transponder log. That reduces all the issues to the same as those with using counterfeit plates, which we've lived with for over a century, without major problems.

(In fact, I suspect they're already keeping the photo logs, but time will tell.)

It's an interesting point. Obviously, if they had you working for the toll system, they'd be able to come up with some interesting countermeasures. Of course, they don't have anyone like you or I working there.
