I'm planning to implement token based DRM solution for media contents as described here.
I don't understand though, how I could limit the use of the tokens to certain media assets.
Let's assume my users have these files:
User A -> happy_movie.mp4
User B -> sad_movie.mp4
If I issue a token to user A, how can I prevent him from accessing files of other users? Obviously I wouldn't give him the streaming URL of those files, but is this supposed to be enough?
