How is it any different to supermarkets who use facial recognition technology to keep track of prolific shoplifters? With ChatGPT these days you can actually upload a photo of someone, a screengrab from CCTV for example, and get it to scan through public LinkedIn and Facebook posts, as well as the Internet in general, to see if it can match the image to the person. So the old defence of saying "a photo of a face isn't personally identifiable" isn't even valid anymore. I think all of us would be surprised how much information about us is held by companies.
