Facebook Will Soon Be Able To ID You In Any Photo 153

sciencehabit writes Appear in a photo taken at a protest march, a gay bar, or an abortion clinic, and your friends might recognize you. But a machine probably won't — at least for now. Unless a computer has been tasked to look for you, has trained on dozens of photos of your face, and has high-quality images to examine, your anonymity is safe. Nor is it yet possible for a computer to scour the Internet and find you in random, uncaptioned photos. But within the walled garden of Facebook, which contains by far the largest collection of personal photographs in the world, the technology for doing all that is beginning to blossom.

    You uploaded all the photos and did all the tagging they needed for this yourself, didn't you?

      • Not on Facebook, but on Google+ one of the first things I did was to disallow tagging of me in photos. It's just a really really stupid thing to tag yourself or someone else in a photo, or from my view anyway (it's been too long that I can't put myself into the mindset of a kid).

      • If I could burn down every data center facebook owned I'd do it in a second, no hesitation.

        Hm, I wouldn't. I'd auction off the hardware, then I would invest half of the proceeds in low risk mutual funds and then take the other half over to my friend Asadulah who works in securities...

        • correction you can't UN TAG yourself if you don't have an account.

          the problem is facebook has a great number of "phantom" accounts for folks that do not have an actual account.

          If your friends/coworkers/enemies ect tag your face (or anything else) with your name FB records this and if you someday do sign up for an account you will by way of your friends and such be linked to the data in your "phantom account".

        No, I didn't.

        Other people have been uploading and tagging me whether I like it or not, despite my not having an account.

        So fuck you it's not been my decision, but I'll be copping the consequences. If I could burn down every data center facebook owned I'd do it in a second, no hesitation.

        It may be more practical to lynch anyone holding a mobile phone in the air with the deliberate intention of photographing you for said sites.

      No problem. You see that nice girl in the street, take pic and immediately FB gives you her address and phone number. Cool. The next day you step on the foot of this unsympathetic guy in the train. He takes a pic of you and during the week-end your house is burned to the ground. Everybody knows everyone, that's great!
      • So you have a woman's name and phone number. Good for you. I have a large book full of them. It still gets dropped on my porch now and then.

        So some guy has your address. Good for him. He could have just as easily followed you home, and there's a very good chance that you never would have noticed.

        Now, both of you have a choice to make. What will you do with that information? Will you get on with your life peacefully, as a law-abiding member of society, or will you jump the line over to being a criminal stalk

    Postgrad students at our faculty were developing face-recognition stuff that can easily and percisely tag almost all photos we were able to stuff in it. In microseconds. I guess it would be really weird if facebook didn't have this technology available long time ago (it isn't really that hard either).

    • Were these rather generous photographs or partially obscured faces wearing hats in a crowd? Was the database of potential people in the billions? Identifying the subject of a selfie at your university might not be the most difficult task, but identifying everyone in an arbitrary crowd [google.com.au] is going to be a lot more involved. The process could probably benefit from being able to map relationships to narrow partial matches down, hence Facebook.

      • Also very hard if there is not a set of reference photographs.

            All shot from almost exactly the same angle, which makes them a terrible source of reference data. To do facial recognition well, you need multiple shots of each person, taken from multiple angles... like Facebook already has.

        • Also very hard if there is not a set of reference photographs.

          Fortunately your friends, relative, and coworkers are willing to help out with that. Each photo uploaded to Facebook with your face tagged in it is a reference photo. Setting your privacy settings to not display those tags doesn't mean the data point wasn't saved.

        I've got facial recognition software running on my netbook. It really is not that difficult to get hold of some very sophisticated shit. It even has the capability of reducing any face to a photofit string.

        If you're thinking "Bullshit!", let me throw some titles past you that a: I use for facial recognition features and b: I consider worth mentioning because they actually work (for some metric of "work" which for me is "enough to differentiate between 60 million individuals").

        Windows Live Photo Gallery
        Google Picasa
        DigiKam
        Adobe Photoshop Elements
        Sony Picture Motion Browser
        AmCap
        IrfanView
        OpenCV
        EvoFIT
        E-FIT
        Faces LE (Law Enforcement edition)

        (those last three are compositors, I do use them to reduce found faces to photofit strings - they're much easier to index that way).

        • by eexaa ( 1252378 )

          Whoa, good list. There are also very good methods to recognize people by non-facial features (especially the ears are something that computers can "fingerprint" very easily and reliably), but I haven't seen that in any software package yet.

      EvoFIT, pretty much the best photofit software there is, has a 70% naming rate (automatic and correct naming of individuals based on a reference set of file photos such as passport database), it's one of the systems the Metropolitan Police use purely for the fact that it can run a photofit against a reference set.

    Sometimes Zuckerberg doesn't understand the boundary between "being able to do something" and "whether you should do it." I wonder if he will be pleased if I stood outside his house and recorded his activities and followed him everywhere to post his whereabouts online? What if I went through his bin and post pictures of that?

      There is already a third party app on Facebook that does that.

      No, because NSA didn't have all the photos. Perhaps some which match those in official documents, in a good light, at some angles, but even they're not going to be able to compete with the billions of photos of people on facebook. Also, their "match or no match" is not as useful as "this person is known to these people"; there's a whole network of people they can hit up/monitor to find where someone is.

    You should NEVER post pictures of your face on the internet, not even "just for" restricted groups of friends. Because someone is ALWAYS there selling you out.

    but Google have also recently taken to autotagging faces in photos you upload to G+.

    • Facebook already had ass recognition up and running.

      I have to retract that claim. I converted the image to .png and it uploaded fine. Turns out Facebook already has their advanced file name recognition technology up and running instead.

    Facebook consists of the single largest privacy invasion ever invented. And they offer nothing that is not free elsewhere on the Internet, if not linked up under one password.

    If the government asked people to do what Facebook asks, there'd be another revolution. But offer them minor services that they could do themselves and they willingly throw away everything Thomas Jefferson fought so hard to give them.

      Not universally or objectively bad, but they are examples of things that a certain number of people might want discretion about. Other people would have different things that they would feel that way about but the underlying anonymity concerns would be the same.

      But of course you already knew that.

    A while back, I read an article about this. Someone suggested "database poisoning".
    It sounds illegal but I am not so sure. All that everyone needs to do is to tag other people as you and vice versa. If enough people did that, it would mess up such a system.

    • When I still had my FB account, I did something similar. I began uploading random images of different people, mythological creatures and inanimate objects and tagging myself in them.
  • I resolved many years ago that I would never be myself on the net. Several years ago I added to that never to post pictures of my face to the net. I guess the next step is to never go out in public without my randomly-generated mask.
