Facebook AI Research alters video to make people invisible to facial recognition

Amazing!. The actual research paper: https://research.fb.com/wp-content/uploads/2019/10/Live-Face...

As super interesting this is I'm not sure yet how this could be deployed for people who are concerned about their privacy in the short term.

If you didn't put pictures on to social networks and only sent stuff end to end encrypted your family and friends can see the images / videos.

This is cool. But I also wonder how deterministic is their process, and whether it may be reversible, especially if you have the original model in hand.
