Casinos take ~80 photos per minute on the Las Vegas Strip. Street
cameras, red light cameras and such, too.

But those don't bind a unique identifier to the photo. My fingerprints
exist on thousands of "public" (i.e., freely accessible without a warrant)
items every day. But, even if someone wanted to "lift" them, they still
have to be tied to my name, address, etc.


Casinos have had sophisticated facial recognition software and they
may know a lot more about you than you think.
My sister was a power player at the Sands in AC and they would meet
her in the lobby with a gift box of personalized stuff, a few minutes
after she walked in and before she had actually checked in or swiped
her betting card anywhere.
They knew what brand of scotch my BIL drank, what cigarettes they
smoked and what kind of bath oil she liked.
This all came from a hit on the lobby camera.
