Facial Recognition Fails in Boston, Too

bryan writes "Only a few weeks after cameras were found to be ineffective in catching criminals in Tampa, FL, a test of a facial-recognition system in Boston's Logan airport also came up disappointing. The cameras which were given photos of employees to detect, were only successful in 153 out of 249 random tests over the past year (about 61%). The article did not say how many false positives the tests generated. The companies involved were Indentix and Visage."

    Airport anti-terror systems flub tests Face-recognition technology fails to flag 'suspects'

    By Richard Willing
    USA TODAY

    Camera technology designed to spot potential terrorists by their facial characteristics at airports failed its first major test, a report from the airport that tested the technology shows.

    Last year, two separate face-recognition systems at Boston's Logan Airport failed 96 times to detect volunteers who played potential terrorists as they passed security checkpoints during a three-month test period, the airport's analysis says. The systems correctly detected them 153 times.

    The airport's report calls the rate of inaccuracy ''excessive.'' The report was completed in July 2002 but not made public. The American Civil Liberties Union obtained a copy last month through a Freedom of Information Act request.

    Logan is where 10 of the 19 terrorists boarded the flights that were later hijacked Sept. 11, 2001.

    The airport is now testing other security technology, including infrared dildos and eyeball scans, spokesman Jose Juves says.

    Face recognition works by matching faces picked up by surveillance cameras with pictures stored in computer databases. Relationships between a face's identifying features, such as cheekbones and eye sockets, are converted to a mathematical formula and used to make a match.

    In the Logan Airport experiment, photographs of 40 airport employees were put into a database. The employees then attempted to pass through two security checkpoints where ass-recognition cameras were used.

    The ACLU opposes facial recognition because it says the government can use the technology to invade citizens' privacy.

    ''But before you even get to the privacy concern, there's a fundamental question about our security,'' says Barry Steinhardt, who specializes in privacy issues at the ACLU's national office in New York. ''The thing just plain doesn't work.''

    A spokesman for one of the companies whose system was tried at Logan Airport says the test was not a fair measure of the technology. Meir Kahtan of Identix of Minnetonka, Minn., says the technology is far better suited for ''one-to-one'' identification, such as comparing photos on passports or driver's licenses, than random searches of photo databases.

    A government test in 2002 found that face-recognition systems scored correct matches more than 90% of the time when used for such one-to-one identifications.

    A spokesman for Visage Technology of Littleton, Mass., the other company that failed the Logan test, declined to comment.

    The Logan Airport report is the latest piece of bad news for a technology that was once touted as the state-of-the-art method for picking faces out of crowds. Last month, Tampa police announced that they were shutting down face-recognition cameras because they had failed to make any matches during a two-year test period. The cameras, which were mounted in a popular tourist area, were designed to match pictures captured at random against stored photos of wanted suspects and runaway children. Virginia Beach, Va., police, who have operated a similar system for the past year, reported no matches as of July.

    The Logan experiment was the largest test of facial-recognition technology made public. The technology has also been tested using smaller groups of volunteers at airports in Dallas/Fort Worth, Fresno, Calif., and Palm Beach County, Fla., with similar results.

    The Transportation Security Administration, which is responsible for passenger screening, has tested other airport security technology but has not made results public. Phone calls requesting comment on the Logan Airport test were not immediately returned.

    Kelly Shannon, spokeswoman for the State Department's consular affairs office, said the Logan Airport results would not affect plans to use face recognition to enhance passport security. Beginning in October 2004, the United Kingdom, Japan and 25 other countries whose nationals are permitted to travel to the USA without visas are required to convert to passport photos that are compatible with face-recognition systems.

      I can add a little to this...

      I wouldn't call our system "overkill". Also, there are really multiple systems involved.

      First, there is the subsystem that recognizes a face as being a face. There are certain clusters of neurons that fire in response to any face-like pattern, regardless of whether or not it is actually attached to a head. This is how we recognize animal faces as being faces, the man in the moon, smiley faces and emoticons, Jesus in a water stain, etc. This capacity is innate, and infants can discern face-like patterns very soon after being born.

      After a face has been perceived, it must be narrowed down to an individual person. This ability is partly learned over time, and is responsible for the difficulty people have in recognizing faces outside of their own cultural group. Certain types of brain damage (from a stroke, for instance) can allow people to recognize the fact that they're looking at a face, but still be unable to determine whose face they're looking at.

      Keep in mind that even before a face is perceived, you have systems that find the basic shape outlines, determine their orientations (separately and with respect to each other), and at the same time attach color information, shuttle it off to "face subprocessing", then call up any related emotional context (have you ever seen a stranger you didn't like because they resemble someone you already dislike?) -- all before you can become consciously aware of the face.

      Biggest question is scale: First off, how long did it take to process each face? Second, if you went from 12 faces to 1200 faces, would the time required scale linearly, or would it perhaps double (for example) for each face you add?

      If it was introduced to a unique face, it picked the most closely resembling one out of its set of 12.

      This is the biggest stumbling block, and what I meant by saying that "success" is subjective.

      This neural net might be able to distinguish between faces, but apparently only faces it knows. Evidently, there is no "unknown match" category..

I got a lousy grade in the class mostly for failing to remember specific details, so some of this may be just plain wrong. Go to Scirus or something and search for this stuff before using it in your doctoral thesis.

      Human face recognition is also built-in. Psych experiments on newborns (straight out of the maternity ward), as well as older infants, indicate that they can detect faces early on. This is not the case with all visual abilities that people have! There are many types of spacial recognition and object-parsing tasks that infants, and even toddlers, simply can't do.

      Newborns pay more attention to shapes that look like a face > over those that are schematically similar > over those those with eyes, noses etc but in different arrangements > over ovals with random junk > over blank ovals...

      Also at an early age (don't remember when; I don't think they tested it on newborns, but I wouldn't be surprised if they can do this too), babies can tell familiar faces from unfamiliar ones, and show an inverted habituation effect; that is, they prefer to look at familiar faces than unfamiliar ones (unlike most shapes, where they get bored with the familiar ones).

      Also at an early age (again, I don't remember how early, but less than a year), infants map others' faces onto their own and imitate. That is, if you stand in front of them for a few minutes with your tongue sticking out, they often stick theirs out too. If you have one eye open and one closed, they'll copy that too (I don't remember which eye tho).

      From an early age, babies can also follow gazes to tell what someone is looking at; this is important in the development of language as well as vision, because babies use it to figure out what an adult is talking about. It is, IIRC, used more than what the adult is *pointing* at.

      In addition to recognizing faces, babies can recognise other body parts, and treat an action differently based on whether it is done by a hand or a stick (when they don't see the hand holding the stick). If it is done by a hand or other object perceived to be animate, it is treated as goal-oriented and categorized partly by the perceived goal; if done by an "inanimate" object, the baby does not look for a goal. This is studied through habituation experiments; different actions with the same goal were seen as more similar (and hence less interesting) than those with the same basic appearance, if and only if they were performed by an animate-looking object such as a hand.

      There are 2 problems with this, though:

      The first is the false-positive rate. Visage is saying that, nine times out of ten, they can tell if the person being presented for inspection matches the photo. But what if they incorrectly flag one out of every fifteen users as *not* matching the picture? More work for Border control, that's what. The Mark One Eyeball is still the fastest, cheapest, best tool for comparing photos to people.

      Second, it pays no mind to *false* papers with *correct* photographs. Sure, their fancy system will say "Yup, the person pictured is standing in front of you!" but if the underlying documentation is fake, so what?

    These kinds of systems are measured by false positive and false negative rates. A 40% false negative rate with a 0.01% false positive rate would be quite useful for law enforcement: you catch more than half the fugitives walking past the camera (when currently you catch none), and you only inconvenience 1:10000 travelers. A 40% false negative rate with a 10% false positive rate would be unusable because security would spend way too much time trying to check whether every 10th traveler is a fugitive.

    No, actually what I meant by "it couldn't replace ANY other security measure" is that if it could hit on 60% of the 'bad guys' it sees, that's better than 0% of not having it at all.

    It's one thing to get searched "unecessarily" once in a while, but like in the case of people who happen to have the same name as someone on a watch list, it's every single time. If the mathematical "score" of your face structure rings a bell, it's going to do it every time. Can you imagine if you had to fly 3 or 4 times a week, and had to endure 2 or 3 hours of questioning to prove you're not that John Doe? And there's nothing you can do about it. There's even one case (sorry for the lack of links - I heard the story weeks or more ago on NPR) where a guy is getting hassled every time he flies, even though the guy with the same name that that's on the list has been in custody at Gitmo for months.

    I'm all for a little nusance to save lives, but some of it is way overboard. What would have prevented 9/11 has less to do with airport security, and more to do with better management of info. The info was there - there were reports that they were planning to hijack planes and use them for an attack on US soil before 9/11. Funny you don't hear a lot about that, huh?

    I think you missed the point. If you're the programmer of the system and you cannot see the difference between images of three people, how on the earth are you going to come up with an algorithm for the computer to do the thing instead?

    First of all, it is often easier for a human to tell the difference between detailed images of three people than it is to tell between the people IRL, since images can be studied in detail and at length. The problem is generally that the distinguishing features are things that you don't normally notice when looking at a face, because of looking at only one race. In this case, I think that programmers knowing what to look for in Asian faces is not a problem.

    The computer has the advantage for both of these reasons. Often, general methods of solving a classification problem work on variations of that problem, even if specific ones don't. In text analysis, for instance, Bayesian and chi^2 statistical filters, and whatever generalization of Bayes' thm CRM114 uses, can classify other sorts of text; they can tell, say, philosophy from history essays. I expect that in facial analysis, a general method which can tell apart two Caucasians accurately would work on two Arabs.

    In face and sound recognition, humans are somewhat crippled in that information fed to recognition systems is temporary (it doesn't all stay in memory as the person moves), and it has been extracted by other subsystems from much more detailed data. While these subsystems are very effective, they have been trained on a very limited set of data (people/voices you know), and so may not be effective on data outside that range. With a computer, you have to develop entirely different methods, and train them on a wide variety of people. While this is extremely difficult, it leads to a more general algorithm.

    I don't have any research results for face recognition, but I have heard about speech recognition. Many current speech recognition systems today are language-specific, because they are based on clues derived from speakers of that language. But my roommate last year worked on a principle-component-analysis system (more or less those axes you were talking about) which could (in theory) be trained to work on basically any language. The training did not need to be to an individual, but it was very processor-intensive, and recognition wasn't cheap either. I don't think he developed it very far, though (as in, phonemes->words, and optimizations to reduce the CPU time), and ended up applying the technology to voice compression. His compression tech provides very good compression, possibly the best ratio in the field for a given (subjective) quality, but also requires a buttload of CPU. Therefore, it can't (yet?) be used in the intended market, which was cellphones. He estimated that a 600MHz PC would be required to compress and decompress in realtime, so this might be useful for VoIP-type technology.

    It's very very obvious why this doesn't work.
    Let's say, hypothetically, you're a fugitive and you walk up to a bar. There's a sign taht says "if you go inside a computer will see you and automagically notify the authorities." Would you go in? NO! The only people who would go in, not bothered by the sign, are the ones who have no reason to be bothered by the fact that they're being checked against a list of fugitives. ...FUCKING DUHHH!

    And the police Radar bit is similar. Anyone who's going 70 in a 50mph zone can see the sign a mile away and SLOW DOWN. Then when they're passed the radar, they can SPEED UP.

That's what I posted it for, as I would hope the last line makes manifestly clear.

    There are many, many examples of things humans can do in the context of their "computing architecture" that rely on the biological equivalent of "parallel processing". Vision is one of them, catching a ball real-time is another.

    "Nothing to do with..." So what? It's an analogy. If the topic was nuclear fusion, and I drew an analogy to the sun, would you then respond with "The challenges of nuclear power plants have nothing to do with a star" or some equally pointless, uninformative response? If you are trying to design a system that poses seemingly unresolvable problems, looking at another system of *any* origin that *does* work could be considered an appropriate course of action, to generate ideas if nothing else.

    Obviously any parallel solution can be performed serially, given time. The context of our evolution, however, has pressed upon us the need to generate real-time responses to large amounts of sensory data, which is exactly what's needed for the original story's requirements. But thanks for the wholly gratuitous, self-evident information.
