> Some people might want it, but it doesn’t actually work Why do you think they can't prevent on-device screenshots/screen recording can't be prevented when you control the entire stack?

Would it work on Mac?

  Yes. Edit: But yeah, nothing to say why it can't work. So, yeah.

    But MS doesn’t control the whole stack there.

      Apple provides APIs to do it.

      Doesn’t matter. I don’t know why you think stating random things matters.

It's kind of like locks isn't it? It'll deter honest folks, but will it prevent screen capture when Teams is running in a VM? What about over VNC?

  What about a camera? These aren't the use cases that really matters. What matters is the common case, and it's not about deterring honest folks. Honest folks aren't recording. This is really a lesson in security blind spots. The number of people that are trying to "get around this" assuming that's the issue. Edit: I'll make it simple. It will work because honest people aren't trying to get around it. But, they could still expose data they shouldn't. This helps prevent that. Again, a camera is enough to prove it doesn't need to be 100% perfect (and probably more honest considering screenshots can be faked). So, instead of trying to think of how you can exploit, think of all the ways this private information can get out when it shouldn't and the people on the call aren't trying to release it. Work through that, and see where you get.

    > Honest folks aren't recording. Honest folks who want to be able to cover their ass later on are. Honest folks who are working for dishonest people and are planning to be a whistleblower are. Honest folks who have Recall on are. Possibly against their will if they haven't found out how to turn it off, or it's a work machine where they're not allowed to do so. Maybe they're not if Microsoft actually has enough interdepartmental communication for the "no screenies please" signal to make it all the way to Recall. It'll be hilarious if they don't.

      One of the best rules I ever heard of was told to me by a cop here in Australia. She told me every time they unholster their firearm, they have to fill out about 3 pages of paperwork. I think that’s so genius. Think about it - if you’re in a life or death situation, you won’t hesitate. Your gun is right there, and it’s there so you can use it. But if the situation doesn’t feel dangerous, the image of having to fill out 3 pages of paperwork justifying your actions is enough to make you hesitate. It’s weaponised bureaucracy. It’s like - there’s an ideal amount of friction for some actions to have. Pulling your gun out should have some friction to it. The choice should have weight. I see this in just the same way. If the presenter doesn’t want their presentation recorded, there should be some friction to recording it anyway. It shouldn’t be impossible to record. But it shouldn’t be as easy as just taking a screenshot in windows. Just like that cop with a gun, there should be the right amount of friction for recording a meeting against the wishes of the presenter. How many pages did the cop have to fill out? 3 pages. Not zero. Not 100 pages. How hard is it to record a meeting despite this protection? It’s doable - you need an hdmi capture card, or a camera out of shot, or something else. You probably need to set it all up before the meeting. And so on. It’s not impossible. But it’s not trivial either. That sounds just right to me.

They can't control the entire stack because of the analogue hole
