Awesome, this was really needed. No, this isn't a "security" feature and it obviously can be easily circumvented. The reason this is useful is to make it extremely clear to participants that the contents should not be shared by them.

I think this would be true if this feature was optional. Then if a particular meeting had it on then you would think twice about capturing the content, but if it's always on even on some team games night then its devalued.

That's quite unfortunate because due to a screen capture through Snipping Tool I got evidence of my org planning to fire me before even making announcements through a shared PowerPoint deck with a slide containing a org chart which shouldn't really be there at the time in the Teams meeting.

So from a employee POV it has its uses.

But people who will get in the same situation like me could simply use the camera on their phone pointed at the screen and be done with it, I guess.

Any security feature that can be totally defeated with a spicy HDMI splitter and a 2nd computer should not exist. This stuff looks much more to me like "fuck the user" than anything else. I am 100% convinced there is a cult of evil bastards at Microsoft, et. al. that is hellbent on making everyone's UI/UX as janky as possible.

No. It is there to protect an organization from itself. It tells the participants that the content should not be shared by them. It is essentially like a watermark in a PDF. It can be trivially defeated, but that isn't the point.

If they wanted something like a watermark, they could have just added a watermark...

I think that it might more have legal implications than practical ones. It wont protect the organization from information exfiltration, but it might legally protect it, in the sense that a court might state that the necessary technical measures were there, so the organization is not responsible for the data leak that happened... or something in that direction.

The workaround that Microsoft is officially supports but isnt mentioning it.....is using microsoft recall.

Yes. Don’t take a screenshot of your teams meeting, you aren’t trustworthy. We will block that while we take a screenshot of everyone’s computer every couple minutes and run an LLM on it.

What's to stop me embedding a pinhole camera in the lamp behind me, zooming it in on the screen, and recording every meeting? These kinds of measures only stop the good guys from doing their jobs. The bad guys put way too much effort into espionage for this to work.

That's the equivalent of sitting in a movie theater with a camcorder. Not important enough to bother crafting a solution for.

I would say it's completely different. A camcorder movie has bad quality, most people would rather pay for a good quality movie than a free camcorder one.

For sensitive data on the other hand quality doesn't matter as long as it's readable.

They could just integrate Web DRM APIs like Google Widevine, Microsoft PlayReady, and Apple FairPlay, as both of them are integrated into the operating system and only work with a supported monitor. An HDMI splitter would likely not pass the test.

Streaming services like Netflix and Disney Plus use these APIs to protect their content as well.
