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…

It may be because you are simply stating that it is being done without any references to actual projects which might back up and add some value to your statement.

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…

The thing is, under a certain age everyone is doing it. When this current teenage generation grows up and gets into leadership positions - especially politics, they are all going to have their entire upbringing exposed for the whole nation to see.

The few that haven't will be viewed with cynicism and will most likely not be accepted by the population.

The population will be voting for their leaders based on how they were brought up.

It is going to be quite an interesting social phenomenon to witness.

I wonder how effective systems like https://cvdazzle.com/ are against this. Will we all be putting on masks or face-paint in the future when we go outside?

You would need to somehow convince the population that looks are no longer important, or that somehow looking like you were a member of the band Kiss is now a popular look. It's not impossible, fashion changes all the time.

This is an unbelievably ridiculous argument, the government has data on almost entire population thanks to all sort of identification cards and other innumerable sources of data. Why should corporations and other people be denied the same access & privilege.

You are spreading pure FUD, out of ignorance and misplaced sense of paternalism. The reality is that most people correctly understand the trade-off between privacy and utility. That's why they share information on social networks. They are not paranoid running around fearing government conspiracy theories. They just want to enjoy their short lives.

It sounds that this would be a great tool for street scammers. At least the performance of the malevolent fortune tellers should be improved considerably. Find a gullible mark, research their life a bit and then perform the act.

Earlier quoted context omitted.

Do you expect police to come every time you see a stranger?

I can imagine things getting to the stage where someone not being findable on the face register is considered suspicious enough for police attention.

Being recognized by police and being recognized by random John Doe are different things.

>> “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?

The Google FaceNet and other similar system typically perform an approximate nearest neighbor search in a ~128 dimensional embedding of faces.

Here is the paper for the reference: http://arxiv.org/pdf/1503.03832v3.pdf

Also 70% accuracy is like really really bad.

Here are results from MegaFace Challenge, which involved identifying face in presence of Million distractors:

So what you're saying is, just because our governments collect everything, everybody else should be allowed to do it too, or stop worrying?

The fight for privacy is not for us, it's for generations to come.
