But only if you published your photos in public. If you dont spread your photos around the web you still safe in crowd.

What if retail stores take your picture and then match it against your credit card at POS and then automatically identify you in the future as well? I can't imagine this is too far off, if it's not already happening.

That's the thing with personal pictures online. Most people can't imagine what is going to happen in the future. People on Hacker News well understand this issue, but ask your non-computer friends and family. If you'd tell them, that you can take a picture of a random person and search that picture out of a pool of people and get their contact info (as a private company / random programmer with enough data), they won…

So true. And even if you're careful with your own data...some other person might not and upload and tag photos with your name.

It honestly may be more productive to operate under the mindset of "My private information that is acquirable by a cursory examination of me (this includes face, which is obviously publicly visible) will inevitably find its way online in a way outside my control. What do I do given this reality?"

>> “With this algorithm, you can search through a billion photographs in less than a second from a normal computer,” With Intel Core i7 5960X (238,310 MIPS at 3.0 GHz), it only takes 238 instructions for a photo?

It's likely using a nearest neighbor or tree search; it might take a billion instructions to process a single photo and another billion to do the nearest neighbor search.

That's a really hard battle to fight, even for those of us who understand the full implications. The entire population is not going to drop facebook overnight, it does deliver some sort of value to them despite it's heavy privacy price. I'm beginning to believe that the answer is to simply devalue all that information. We can do it in some contexts on the technical side, for example, rotating passwords devalues stole…

I have hope that this will change. Because more and more people live a fake life on social media. Some people go crazy and share everything, but more and more people share less[^1] and if they share something, it's only something that holds together their "clean image". 1: http://www.theverge.com/2016/4/7/11387604/facebook-personal-...

Sure, that's a good sign, but it's still undone by someone else who posts a photo or recording of you. If I recall correctly, facebook used to (maybe still does) solicit users to "report" anybody who is not using their real name on the site. When will facebook start soliciting/rewarding users for uploading photos of others? How much does that guy in your class value your personal privacy?

Now aggressively poll the new images with GPS location from Instagram/Twitter/Facebook, identify every face in sight, and build a realtime map of everyone everywhere! (Actually for a lot of shots you could probably get by without the GPS location by recognizing some landmarks in the background)

>> "Actually for a lot of shots you could probably get by without the GPS location by recognizing some landmarks in the background" Yes, this is already being done. EDIT: Curious, why this is getting downvotes, any thought on why? EDIT-2: Here's an example, though the general gist is you grab millions of photos with geo-location meta data, then train against this to ID the location of photos without the location meta…

Because the comment suggests, without offering any evidence, that there is a coordinated or automated large-scale effort underway to carry out the previous comment's plan.

Honestly, this evolution became obvious more than 10 years ago. Btw, Snowden is about illegal mass surveillance by the government (in collaboration with tech corporations). The app mentioned in the article however only connects publicly and legally available data (the consumer's fault).

> (the consumer's fault). I doubt that. No one prevents someone tagging me on Facebook even if I don't have a Facebook account. Now Facebook knows my name and the corresponding face without me ever using Facebook.

Well you can't do that. You can only tag someone with an account.

From a purely technical point of view: Does anyone knows what they are using for face matching? their results sounds excellent.

There was an article recently on that, light on actual technical content though.

technology is a double edge sword. We'd better adopt a Snowden mindset.

Agreed with everything except "The consumer's fault." It's the data age now; information about you will make its way into the global repository without any direct action on your part.

- If you're a professional, someone is providing a way for your customers to audit interactions with you

- If you're a driver, someone is tracking your car's movements

- If you buy products, someone is tracking you bought them

- If you ever communicate online, someone has logged that communication

- If you're ever seen in public, someone can tag your face

... and after all this, if you piss an individual off enough, that individual can create a pastebin and drop as much of your personal info on there as they care to.

We're already past the event horizon of private (easily-gleaned) information staying private; it's time to re-organize the solution space around the assumption that the information is public.

Exactly. We cannot have any expectation of privacy in public and likewise, we cannot have any expectation of privacy in online social media.
