This is the cyberpunk future. Finding bodymods and shirts or stuff that hides you from the algorithm is the new pasttime.

Hiding your face is already illegal in the uk.

Everyone will walk around with hoods and glasses to cover their distinguishing characteristics (eye-nose-mouth measurements, ears, etc.).

And shims in their shoes to hide their gait, and enclosed in plastic to hide their scent from artificial noses and to prevent shedding DNA, and they'll sneak around the sewers to hide from satellites, and carrying lead weights to hide their mass from for sensors, and foil suits to hide from mm-wave devices in doorways, and fake irises to hide the iris pattern viewed in non-visible frequencies, ...?

Hoods and glasses only work if everyone is doing it. In certain parts of my town you can tell the drug runners by their "uniform", primarily pulled down hoodies and a hand down their trousers.

I'm not sure I follow your logic. Your experience seems to prove the point that pulling a hoodie down helps conceal your identity, I assume that is why the drug dealers do it.

The focus of the article is facial recognition, which is commercially available today. Your examples all require some type of initial identification to know where to check for someone's mass, scent, DNA, etc.
