You could improve (but not solve) the problem of raw access to data. But that does nothing wrt solving the "problem" of recipients storing a permanent copy of received snaps -- all they need is a camera.

It's a little like the old (tv series) adage of don't discuss crime in a car -- it's easy to place a bug in a car, so assume that it's bugged, if you have reason to fear someone's bugging you. Even if you're using encrypted phone/voip-chat -- that won't help squat if there's a microphone in the vicinity that can pick up both ends of the conversation...
