I should have been more clear what I meant here. “It’s possible with more than just locations” means that, just like you can uniquely identify any location on the planet if you can extract enough bits of information out of a picture, one can uniquely identify people if they can find log2(human population) ≈ 33 unique bits of information on them. Gender, for instance, is one bit of information

EDIT: Whistleblowers should probably mask their writing, on second thought. Thanks—I’ll add this.
