I am looking for an App for my students. It will primarily host recorded lectures which the students can watch after they log-in. The most important feature must be that it shouldn't be possible to download, screen record, or take the lectures offline since they are copyrighted and are paid for by the students. Let me know if you need more details. Please send me a reasonable quote since I am a budding teacher. Thank you!
I would have applied to this cause I love projects like these. But I am not going to due to your requirements. I will boldly tell you that it is not entirely possible to prevent users from recording an offline version. First of all, Users like me will certainly be able to download videos from such an App (Just the same way even the great Google cannot prevent Youtube video downloads). But assuming we could come up with some "state-of-the-art" security solution that actually makes it impossible to do that, You really cannot prevent recordings. This is the unwritten rule: As long as the video plays, it can be recorded. There's just no way around it. If u really do not want it recorded, then you will end up with something that doesn't play in the first place.
