I think they just picked the two most striking examples for that article. Look at the rest here: https://birdinflight.com/ru/vdohnovenie/fotoproect/06042016-... Most of them are clearly the same person.

I dunno. Some of them clearly are because you can see they have moles in the same place and stuff like that, but a bunch leave me dubious. For example, that woman with the dyed white hair: the hair looks much frizzier/curlier in one than the other. And some I wonder how the face algorithm could possibly have matched them up - the guy in the parka vs the soldier don't even have the same facial hair, never mind how the…

Did it have to match those exact photos? I think he took a photo (or a few), used that (or those) to find the social media account(s). Then he could use whatever photos of that person he wanted to match up with a photo he had teken.

Oh yeah I think it was clearly manual. He uses this app to find their VKontakte account, and then he picks a good picture from their page. It's an art project, not a study.

How long before anti-facial recognition makeup, hair, and accessories becomes fashionable? https://cvdazzle.com

I'm reminded of the comic book/graphic novel Private Eye [1]. [1] http://panelsyndicate.com/comics/tpeye

I don't see why this can't be done in real time. Point your phone towards a person in a cafe and immediately figure out her name, age, maybe relationship status, social class, augmented reality style. 5 minutes later accidentally bump into her .. and start a conversation, armed with lots of private info about the person. Or even more basic - thieves picking their targets - is this woman's purse likely to contain a lo…

It's just a matter of time. With implications we can barely imagine today.

Think about it in reverse. Think about every photo in existence anywhere that has you in it, or has your stuff in it. Imagine all of that being tagged and cataloged as being tied to you. A selfie your friend took in your house with your kitchen in the background. Somewhere somehow the data is crunched, algorithms are leveraged, and these things are figured out. A lot of this isn't even a particularly hard problem, your social graph is already known, your address is known, people share their locations all the time, the people you hang out with is known, it's a simple problem of deduction to figure out all this info. And then there's an amazing degree of data that can be extracted. Imagine a database containing a list of everything you are known to have in your house, and when, and changes to that. Imagine tracking your whereabouts and who knows what else by the presence, or absence, of your self or your accouterments or your car or what-have-you in various locations in the backgrounds of other images.

We really don't have a good sense for the implications of this level of data becoming available to anyone and everyone.

That doesn't seem like it would work at all. The makeup and hair styles suggested would make you stand out even more! Sure, 1990s-style facial recognition won't work as reliably, but surely today's systems would flag you right away!

Note this is designed to fool facial detection, not recognition. Detection generally uses much simpler algorithms because in most cases it needs to be orders of magnitude faster.

I was working on a project with OpenCV a few years ago. After a few embarrassing incidents I had to add a kludge whereby if it detected a small face directly above a big face, it was to discard the big one.

It turns out that the torsos of portly women with large breasts make ideal face candidates.

No need for the images to be public. A police state could match images taken by street CCTV to e.g. the drivers license database and track the citizenry in real time. You could easily reduce the search space to match a face taken by a CCTV camera by using cell phone location data to limit it to people in the general area...

A police state has always been able to do this. Of course it gets easier by automatic face recognition and the possibility of sharing databases over long distances etc. The difference from before I guess, is that it's less in your face, and can thereby happen without people noticing as easily.

>A police state has always been able to do this.

Not for everybody all the time, though...

Holy moly, that's a very curious side effect of technology on culture. Crazy cyberpunk look necessary to avoid computerized detection. I can see this being the norm or strictly banned in the future.

my bet is on such looks being banned.

What do you have to hide? /s
