Preventing screen capture hot key combinations

[Terry Judd]

Hi Scott - it's for running MCQ tests where the questions and responses need to be protected (medical progress testing). The tests will be run in an invigilated environment but we're looking to minimize the potential for copying as much as possible. There is a commercial solution that uses a customized 'locked down' browser that purports to prevent screen capture but it's pretty expensive.

Hiding the app on suspend works well and I can easily empty the clipboard, but the hot key thing is a definite barrier.
