Can BBB hosts detect screen recording?

[Günter]

Hello everyone,

I have a technical question regarding BigBlueButton's monitoring capabilities.

In a recent lecture, an IT professor repeatedly removed a student from the session, claiming he could see "digital footprints" indicating that the student was recording the screen.

From a purely technical perspective (browser sandboxing), external recording programs (like OBS or Wondershare) should actually be invisible to the web application.

My question: Does BBB truly have a feature that displays such local recordings to the host/moderator?

Thank you for your insights!
