The user in this case is the presenter who clicks the button to enable screenshot protection on their meeting. This is Microsoft trying to deliver a feature their users want , not laws and regulations making them do something their users don’t…

But it’s literally the dumbest feature ever. There’s absolutely nothing preventing a user from pulling out their phone and taking a picture of any slide they want. Or having a camera recording the whole session out of view of their webcam. It is security theater at its peak.

In a 1:1 format this would be effective in preventing some forms of misuse because it would be obvious if an individual took out their phone and pointed it towards the screen.

I get that it’s basically impossible to enforce but who are all these people that screencap stuff from Teams meetings? Why do you need to do that? Can you not get the actual material you’re capping via somebody emailing/sharing the actual file? If not, why? Are you not allowed to access it? Or are you all just taking candids of your coworkers for your own devious purposes?

I do it just taking notes alongside the slides as the presenter goes through. Most PowerPoints have 1 to 3 actual useful slides.

LOL Another stupid feature (enforced by regulations/law/policies) that has no real world use, besides making us users angry :-( Like Google collecting all of our location history for their own usage, but not allowing us to see it via web anymore (only on mobiles), or having the android dialer not allowing us to record our own phone conversation (easily circumvented), or movie/music/game publishers not allowing us to…

And what is the point? If I want to capture something, I can use my cellphone even if print-screen is not working.

It's not pure security theater, there are a few clear gains for those who care about such things:

* Naive screencaps are much less traceable to the leaker than a naive photo is. Yes, someone can strip out EXIF data, but we've seen over and over again that they generally don't. And even without EXIF a naive framing on the photo is more likely to expose information about the location or identity of the person who took it.

* A photo of a webinar is going to (barring serious postprocessing) look much less official and be less legible than a screenshot, so the use cases for illicit captures are going to be fewer. Few people are going to try to take a phone photo of the top-secret meeting and use the slide in their next team all-hands, but many might forget the rules and than snap a screenshot really quickly for later use.

* Just having the ability to block the easy method of screen captures helps avoid cases where the person doing the capturing isn't actively malicious, just ill-informed. If a normal employee attempts a screenshot and is reminded they're not supposed to do that, they're not going to pull out their phone to take a photo, they're going to say "oops" and move on.

Yeah, there are threat models that won't be stopped here, but most of corporate InfoSec is wrapped up in protecting against pretty lame threat models that would benefit from this—mostly uninformed/ignorant employees screwing up without intending to be a threat.

Easily circumvented: Use two monitors, one positioned out of view. Use a teleprompter mirror with a camera behind the mirror. Use a video capture device, record on a separate computer. I'm sure there's sneakier ways to perform this...

Or… y’know having a HDMI capture box with a trigger pedal.

Doesn’t hdcp take care of that? 720p over component sure but hdmi has protection for this.

You turn your camera off for 10 seconds, take the photo and turn the camera back on. No-one would notice a thing

If you wanted video just have the device positioned outside the field of view. Laptop cameras fov is very narrow.
