title: How to use php and s3 to share private video that can't be downloaded?
body: <p>I have a (php) website where teachers upload recordings of their class, and the students can log in and then play back the recording.</p>
  
  <p>I want to make these videos more secure. Currently, the videos are stored on my server, and anyone with the url can download them. So, (1) I want to store them somewhere that can't be downloaded just using a url. And second, I need to stop them from right-clicking and saving the video as it is being played.
  I'm trying to work this out with s3 but not getting it...</p>
  
  <p>Is this possible? Does it need to use a special player? Does streaming the video help (can any video be streamed)?</p>
  
  <p>I appreciate the help, I've spent many hours researching this and just getting more confused as I go along!</p>
