back to article Reverse-engineering artist busts face detection tech

Concerned about the proliferation of face recognition systems in public places, a grad student in New York is developing privacy-enhancing hacks designed to thwart the futuristic surveillance technology. Using off-the-shelf makeup and accessories such as glasses, veils, and artificial hair, Adam Harvey's master's thesis …

    The face of things to come.

    It's all nice and well for industry buffs to ``predict'' face recognition ``will be everywhere'', just like other (or maybe not) industry buffs ``predicted'' RFID would be everywhere, then proceeded to scam their way into passports everywhere by way of ICAO and a good solid terrorist scare, doing clear but often overlooked damage to privacy everywhere. It's still going to be a problem and another reminder we'll need to think about what we want tracked and where we would like to stay uncounted. Not-knowing is becoming harder every day, but will prove necessairy. Thus we will have to conciously choose. And this requires us the people to speak up.

    This sort of thing is why pious jews and muslims both superstitiously prefer to leave things, camels, people uncounted.

    On the gripping hand, good job to the OpenCV people to provide us with an open source implementation that could then be used for Adam Harvey's work, for which kudos also.

    Using the technology against its self

    Most CCTV cameras are highly sensitive to infrared light, which is helpful since you can illuminate scenes covertly with infrared lamps. However, it shouldn't be difficult to develop face paints which look like normal skintones to us, but which reflect or absorb strongly in the near-infrared. It is also quite possible to put infrared LEDs onto spectacles, which emit strongly enough to interfere with the face-recognition systems..

      As with the spray paint on number plates...

      ....That stops you having your number captured on camera. That will only be effective if the cameras are unmanned (in the case of the plates you are fucked as soon as a cop car with a camera sees you as it wont see your plate). It doesn't take a genious to work out that someone who can't be identified should be checked out by a real person on the ground. It also wouldn't be difficult for the camera to alert an operator to a suspicious reading.

      Basing this 'theory' on open source software is all well and good but lets face it, in the real world, the most secure and advanced technology is not given out for free.

        How's that security-by-obscurity working for you? Only at the upper-ends of military tech are the encryption system themselves secret. And even there the main protection is not letting the certificates/pass-keys/whatever fall into the wrong hands.

        The strongest securith (SSH, HTTPS, TrueCrypt etc) is often quite free and open. This is what makes it secure in the first place. Sure you can see how it hashes its bits and what have you - does you sod all good when you don't have the keys.

        Most advances in this area come from sponsored academic research and, with few exceptions, academics publish their research publiclly (they kinda have to). So even if you can't get access to "Code Cypher X", the theory on how it will work is out there. And if "Code Cypher X" has a flaw, a smart person can still figure out how to break it. Just look at how long HDTV security lasted, to pick one example.

        I put it to you that, barring extreme cases in military-style applications, the most secure systems run on open code. With keys held safely.

      Small, bright point sources of light do a lousy job of 'jamming' CCTVs and the like. It'll work if you strap a car headlight to your hat, perhaps... nothing else is going to be really powerful enough to dazzle the camera.

      During daylight hours, an IR-cut filter applied to the camera would defeat any sort of IR-camo-makeup attempt, though perhaps it might work against night-vision type cameras (though I doubt it very much).

        "Small, bright point sources of light do a lousy job of 'jamming' CCTVs and the like. It'll work if you strap a car headlight to your hat, perhaps... nothing else is going to be really powerful enough to dazzle the camera."

        I don't think he's talking about dazzling the camera -- rather he's suggesting that the pattern matching may rely on patches of light and dark not in the visible spectrum, so use of IR masking and/or emission would change the image that the computer sees into "not a face" without affecting the image a man looking you in the eye would see.

    3. dr2chase

      I was about to say...

      if true, the IR-blocking glasses are "dark", then realized that they are merely sensitive to IR, along with everything else. I don't think this is likely to work; if they see well in other bands, they merely install the same IR coating that I get on my glasses on their lens.

      Most likely you are correct, that is what the authorities will think and that is what most normal people will believe as well.

      Personally, I'm amazed that a ban on headgear and sunglasses is not already in place for all banks and places of commerce. YES, it would be inconvienent for some customers.

      However, it's truly maddening how many times security cameras are foiled by con artists, forgers and the like by simply wearing a ballcap and looking down during the transaction. Even if you catch the person, the jury rightly throws out the positive ID because you can't see their face clearly.

    Suspect techno-scam

    Think about a CCTV camera, even an HD version, scanning a crowd entering a stadium. With the wide field of view to cover the entire entrance, each face will only have a limited number of pixels. And in practice, the actual usable resolution will be worse than that. And they claim to measure various distances of features on the face. To what resolution? How many real (intelligence-bearing) bit combinations will they actually end up with? I smell techno-scam.

    Now if the subjects would (one-by-one) helpfully face the camera (filling the frame with their face), then the numbers start to make sense. But even given that, the technology is being oversold, way beyond what makes any sense.

    1. Jimbo 6


      *Last time I went to a sports stadium* you had to access through a narrow turnstile, individually, rather than running through a motorway-width gap with hundreds of others. So not very difficult to have an x-megapixel camera take a pic of me as an individual from very short range.

    ...I don't think that the researcher is saying that you need to do big swathes of black warpaint to fool the cameras -- just enough of make-ups slightly lighter than your normal skin tone on normally shadowed areas and slightly darker on normally highlighted ones to make it hard for the FR software to know where those marker points that it looks for begin and end. If it can't find those, or "sees" them in places where they, physically, aren't, then it won't match the points on, say, your mug shot so that match won't be made.

    Think about all of those tabloid photos of celebs walking around without their make-up on and how different their faces look when they're not making their cheekbones more proinent and their eyes larger/farther apart/closer together.

    Now add in the fact that the patterns shown in the article tend to make the lighter and darker areas that the system looks for less symmetrical than normal and (if the make-up is skillfully-enough applied) you might have a disguise that won't match a previously made FR image AND won't be outré enough to attract the attention of a human watcher. The big black areas in the drawings are simply showing the sorts of asymmetric shapes that can confuse the system and are the equivalent of dyeing specimens on a microscope slide to make them more visible.

    Sorry, but I'm afraid that the glam make-up can go back onto the top shelf of the closet.

      "make it hard for the FR software to know where those marker points that it looks for begin and end."

      I don't think thats what he is saying. Or at least thats not what The Reg's article is saying.

      They were saying that the system is divided up, there is a quick algorithm which scans a complete scene and says these pixels here look generally like a face or a car or something, those face shaped pixels are then passed to proper Face Recognition Software (i.e. recognise individual faces compared to a reference image).

      The article is saying if your face doesn't look enough like a face to be picked up by the fast algorithm then it's never even passed to the FR algorithm.

      So this might work to hide in a crowd where computers are deciding what to scan, but in an enviroment where the image is passed directly to the FR algorithm in higher resolution/low rate of scan environments such as airport security gates where the video is known be a human face I'm not so sure it would work, at least without error codes being flashed up on the operators terminal giving the operator a reason to look at you more closely.

    "reverse engineering" ... it's open source

    Um, as the creator of OpenCV, I thought this was pretty damn funny. By the way, OpenCV is ... open, so you can just look inside, no need to reverse anything.

    The face detector there is a bit dated -- it works fairly well, but we are thinking of vastly improving it. Often it is used for "friendly access control". For example, on our new robot, we are thinking of not allowing the operator of our new telepresence robot to see video from the robot unless the operator's face is also being transmitted to the robot.

    My point was apparently insufficiently clear. For this I apologize and offer this more-verbose version:

    Wiles proof of Fermat's Theorem is so exceedingly complicated and modern that there's little wonder that Mr. Fermat's book margin was "too small" to contain his proof. In other words, the proof by Wiles reveals that Mr. Fermat was either deluded, or joking.

    Similarly, by the time facial recognition (of the general real-time arbitrary terrorist-spotting variety), *actually* works - years hence - it'll become obvious in hind-sight that the present-day claims must have been pure rubbish.

    Facial recognition to pull bad guys out of a crowd..., for the moment at least, rubbish. A way to extract cash from wannabe Big Brothers.

    But for one of its originally intended purposes its not too shabby at all.

    Take single piccy of unknown miscreant from security footage. Compare said piccy to huge database of known miscreants (or even of liscence photos) and extract small subset of close matches. Hand off to a real person to make a final comparison.

    If /when the technology ever advanced to the point where it can name/label every individual in a crowd, defeating it would still be as simple as injecting an irritant such as bee venom into the eyelids/lips/nose to create swelling

    anybody who thinks

    facial recognition s/w doesn't work should take a look at Picasa
