Uhh, I have no clue. But I would assume that every major store that has cameras (all!) probably feed their video output to a ML classifier for facial recog and dwell times/locations in aisles. And if I were constructing such a system (I'M NOT!), I'd also tie it to the cash registers for complete path history and item purchase history, whether you use a 'shopper card' or not. The only way I think you would have legal standing with a full shorud over your face is if you're a female Muslim adherent. In that case, I think you'd be defended by the 1st amendment protections. Then again, that also sounds like a 2-5 year legal battle assuming SCOTUS would even get involved. But you being in SF, the 9th circuit would likely go in favor of 1st amendment. Long story short, our freedoms and relative anonymity are probably completely fucked. And those that demand privacy/anonymity are few and far enough between that we would be easily profiled in other ways.
