What about those people whose biometric data is being stored but don't have accounts of Facebook?
Our research group recently looked into how to hide from Facebook's face detector. If you're uploading photos, adding white bars around the eyes of the subjects in the photo is the best way to prevent Facebook from finding the face. However, if you're out and about in the real world, even scarves and masks aren't enough--facebook sometimes finds these occluded faces too. There aren't very many easy answers. https://arxiv.org/abs/1602.04504

I really don't like having my picture taken anymore. You don't where it's going to end up. I also do wonder how much infrastructure would need to be added in a country that already has a lot of video surveillance (like the UK) to implement a "find this person" feature, where you could just feed it a photo and it would go looking at all camera feeds.
I kind of assume they have that already. Or have tried to build it and failed due to the usual IT project management issues.
It's far easier to judge who's in your picture among your 20 closest friends than it is to find that face among all two billion Facebook users.
State of the art recognition systems still have a few orders of magnitude of accuracy improvements to go before they can solve that problem.
See the Iarpa Janus project for some recent government+academic-sponsored work on this front: http://www.nist.gov/itl/iad/ig/facechallenges.cfm The task is to recognize terrorists in airport surveillance pictures and such.

Scary, but inevitable, no? As technology improves, it's hard to imagine regulations keeping pace with preventing this sort of thing ... And even if they did, then it would only be used by criminals and governments (while I may call it criminal, they would likely exclude themselves from any such regulation), and I'm not sure that situation (criminals and governments being the only users of the technology) is a better…
And that, in turn, could eventually be countered by the technology that allows anyone to easily modify their appearance any way they want, however many times they want. But then..of course, all such services will be required by governments to keep a complete record of a person's "appearance history." Enter the black market, a la Minority Report.
And then there are other ways to identify a person. Like how they move.
I attended a talk by Stallman last year and he implored anyone who took a picture of him not to post it on Facebook. Now I can see why.

Facial recognition is really scary. This was recently demonstrated for Russia's Facebook, VKontakte, when a service appeared that let you look up people on that site by photo. So people started looking up the profiles of random subway passengers, outing sex workers to their families and friends, etc.

The alternative would be to not go out and enjoy life, which is the worse of the two options.

The scary part is that people are feeding the facebook DB with pictures, and many more data. They did it, they are doing it, and will keep it up, despite everything we told them.
The scary part is that nobody cares.
