Microsoft Teams developed a feature when if you’re using a background and turn sideways, your nose and the back of your head are automatically cut off.
Bug closed, no longer an issue, overcome by events.
Interesting that you bring that up. The most egregiously invasive student and employee monitoring software requires that the subject always face the camera. That seems most ripe for bypassing with the current state of deepfakes. https://www.wired.com/story/student-monitoring-software-priv...
My bank does a much better system where they ask for a photo of you holding your ID and a bit of paper with a number the support person gave you for authorizing larger transactions. It's still not bullet proof but since you already have to be logged in to the app to do this, I'd say it is sufficient.
This case I was on the bank text support requesting to make a transaction of $100,000 in one go which the app would not let me do. So it was a real person on the other side. Bank was in Australia called Up.
This sounds like a good thing. An extra step in a $100,000 transaction to prevent accidents or crimes definitely feels justified if the accounts not marked as normally moving heaps of money like a billionaire or something.
