Why use a salted hash at all? Why not just randomly generated unique tokens?
That said, even with randomly generated unique tokens, I suspect knowing where someone was at two or three specific times would be enough to deanonymize them.
- jacquesm 11y agoYou don't even have to know where. Given enough samples all you need to know is that they weren't in certain places (for instance, at home). Eventually the constraints will line up in such a way that only one car matches the pattern, and then you know all the other places and times too. A sort of reverse sodoku.
