Well in plain sunlight it should work OK. The problem is the plate numbers are limited, you are not injecting random data, just repetitive data.

If you got two different shirts displaying two different plates, you could flip a coin each morning to decide which one to wear before starting your daily jog down the freeway. Guaranteed randomly sampled data

  I think the parent wanted to point out that it’s fairly trivial to blacklist the plates on these shirts and thus remove the injected data. The number of available plates on the shirts is limited, likely they’re not valid plates either.

    This would imply the ability to get your own plate blacklisted.

      That would only really work for the distributor of these shirts, as it would add enough random/inaccurate data to make the real data meaningless. If you made your own with your plate on it, it'd just help the cops identify where you were even when not in your car. It's very unlikely, unless you mass distributed a shirt with your plate, that you could inject enough junk data for your plate to make distinguishing the real data impossible. And while junk plates may add a tiny bit of additional data storage, it's unlikely to actually disadvantage the cops in any way pulling up the data they want on real cars. They have no real reason to blacklist a plate just because someone put it on a shirt.

    It would likely be more expensive, but it seems plausible that it would be possible to manufacture shirts that each have a random license plate number. That would at least make it so that they would have to make the blacklisting local to the area where a given shirt owner regularly travels.

      individually would be prohibitive, but specifying a different set of plates on each order from the supplier shouldn't be too hard. The printing is done digitally anyway, as long as the cuts don't change it should be trivial to specify a new pattern. disclaimer: I have very little idea about the details, I've just advised startups that got clothing manufactured offshore.

    it is still random, it just samples from a slightly different distribution to the uniform distribution over coin-sides. for purposes of jogging down the freeway tagged like a car, the lack of perfectly uniform sampling probably ain't at the top of the list of issues
