Your Selfies Are Insecure. Here's How to Encrypt Them

It will be interesting to see if cellular users choose security over speed: given that ads are the big profit center for content providers, the efforts to seek lizard-brain keywords for them will continue, but the fact that they are being shown won't change no matter how well they're targeted, so I don't see much of a future for encryption apps.
