Screenshot/screen sharing detection

[BurkusCat]

I had a thought that could potentially be applicable to this plugin. Instead of preventing screenshots/recording, could it be possible to detect when a user has taken such actions? On iOS, preventing screenshots/recording is quite difficult, but is detection comparatively easier? What about Android?

Being able to detect screenshots/recording and issue a warning to users (or notify the backend system if it's a very serious application that users should not be screenshotting) may be more effective. If users are blocked from taking screenshots, there are still ways to bypass the restriction (e.g. using another device to capture the screen). However, if users receive a warning about violating the terms of service, it may discourage them more effectively.

I thought I'd start a discussion on this topic :)
