Where else is this technology being used to screen large crowds? Airports? Government buildings? The subway system? On streets?

Yes, yes, yes, and yes. Why this is not a bigger story and concern is beyond me.

Facial tech. use is rapidly expanding in both the private and public sector.

For instance, here in NYC there are over 15,000 cameras that feed into facial recognition tech. and Mayor Adams is bullish on expanding it.

Everywhere. And it has some real problems, too - like racial bias.

Yup. People tend not to believe it, but a lot of facial recognition algorithms are trained on biased data sets, mostly the faces of the young white men who do most of the development of those algorithms. Because of this, they'll often match people of color with the wrong face in the database. People of color have been hauled in by the police under suspicion of having committed a crime because a facial recognition algorithm decided they look too much like a wanted criminal who also happens to be a PoC. It's fucked up.

Yep. You have to be extremely careful in your curation of the training sets for ai algorithms and companies often aren't because it costs more. And there's very little transparency about it.

Example one company basically just uploaded pictures labeled from the Internet to a predictive ai to help find criminals. The problem being guess which group of people is massively overrepresented with online pictures labeled 'criminal'.

I'm gonna take a wild guess and say... black men?

Bingo. There were others that had like 100% accuracy with white people but couldn't differentiate between black people causing multiple false arrests.

And all of this is assuming a perfect facial recognition system would even be considered a good idea in a free society, something a lot of people would dispute I think.

Yeah at the airport if you're flying internationally CBP takes pictures at the gate. Deletes after 15 hrs iirc for US Citizens.
