>Both the EU and the US have introduced face scanning at airports to "increase security".
Totally fine with me. Imagine all the cameras you walked by even getting to the new cameras you seemingly have problems with? If you're at an airport, people have their phones out recording all the time. It's public. I want the CBSA to be recording, databasing, post-analyzing including the ability to feed a photo into their database and know who that is. That's the border.
The big question, I'm not sure. Should the data be freedom of information act accessible? I think we side on privacy here; ban the government from sharing the ID information.
>EU rules are currently stricter and US rules allow some opt-outs for people that are uncomfortable with it.
Here in Canada, no significant rules. You can ride on an international flight fully covered except eyes to see where you're going. We recently increased privacy having everyone ride with a mask.
You can opt out of the radiation/xray scans for health and religious reasons.
