Gotta say, I don't think most peoples' threat models make worrying about IRL privacy a concern, but that's obviously not the point.

For the record, I don't use any of these techniques myself, it's just stuff I've read.

For facial recognition, a lot of CCTV cameras don't have IR filters, and can be blinded with Infrared LEDs, so there have been some promising experiments with shoving a bunch of them into hats. You'll glow real bright in any footage, but they won't be able to see your face.

Beyond that, there's always prosthetics (think like what is used in movies) to alter your facial characteristics.

All that said, I believe the main way of identifying individuals in camera footage now is by gait analysis. Supposedly a rock in your shoe can change it enough to not match up between different footage.

You'd also want to ditch your phone or put it in a signal blocking bag, as it can be uniquely identified by the saved wifi SSIDs that it tries to connect to, and by its bluetooth unique identifier (might just be the MAC address), that can be tracked by low energy bluetooth beacons (how stores track customer movement within and how most places did covid exposure tracing with the apps).

As far as fingerprints go, maybe a light layer of superglue on your fingertips to disrupt the print patterns? That's a complete guess though.
