Hitachi Develops Boarding Gate With Built-In Explosives Detector

An anonymous reader writes "Hitachi, in collaboration with Nippon Signal and the University of Yamanashi, have successfully prototyped a boarding gate with built-in explosives detection equipment as part of efforts to increase safety in public facilities such as airports. The prototype boarding gate efficiently collects minute particles which have affixed themselves to IC cards or portable devices used as boarding passes, and can detect within 1-2 seconds the presence of explosive compounds using internalized equipment. With this method, it is possible to inspect 1,200 passengers per hour."

    I skimmed the link, looked like typical marketting pitch stuff. I didn't see any error rates on this marvelous new device. I'm curious as to how many false positives it's going to generate, and how often it will miss carry-on explosives. I'm also wondering how many days I'll need to stay away from the rifle range before I won't show any particulate explosives at one of these checkpoints.

      Relevant comment. Contrary to what most people think, the false positive rate is far more important than the false negative rate. If it has a false negative (i.e. missing real bombs) rate, it will still succeed in its main task, of deterring would be bombers, because they will not take a 95% chance of detection. (Assuming, of course, the false negatives are random). On the other hand, if it has a false positive rate of 0.1%, that is a false alarm for about one in four aircraft boardings, which it totally unacceptable, And, as you say, a recent visit to a rifle range would be highly likely to trigger a false positive. They need to tune the false positives down to less than 0.001% while still keeping false negatives to just a few percent. Which may not be easy.

      Interestingly, one can significantly increase the false positive number if one goes to an airport an sprays around these tiny particles (one only needs little of them).
      Therefore I hope they close the airport if the false positive rate goes up, instead of assuming the equipment is at fault.

      Because, rather than "more metal than expected", which is nearly always innocuous, it say "EXPLOSIVES!". If your X-Ray showed something explicitly gun shaped, as opposed to something just not understood, I bet the grope would be a lot less friendly. If there are explosives, the security staff would be in reasonable fear that they themselves are at risk if a suicide bomber blows himself up on detection, whereas a gun strapped to the back is not yet a danger.

      Yes. On the assumption that the goal of a trrrist is not to blow stuff up, but to create an environment of fear, then anything that makes it easier to create false positives is simply playing into their hands.

      The only effect this would have would be to create an "OMG, there are several baddies a day trying to blow up aircraft" which would increase the demand for security and restrictions. That in turn makes it easier for the bad guys (and the security companies - sometimes it's difficult to tell who's benefiting most) to pursue their goals.

      Well, it looks like something bugged and it stripped out the middle part of my comment.
      What happens when a metal detector has a false positve? You step back, take off your belt, and try again. less than 10s

      When this device has a false positive, you don't KNOW it's a false positive, it just says "I DETECTED EXPLOSIVES ON THIS GUY". Where are the explosives? Well, it doesn't tell you that, so now you have to check everything about this guy, including his luggage, which is probably already on the plane. You are probably going to want to check the luggage of his travel companions because that might be how it got on him. So you are probably going to have to dig out his luggage at a minimum, pull him to the side and do a full invasive search because chemical 'smells' aren't really localized and it could be in his shoe, his undergarments, maybe it was his hair that set off the sensor... etc. Wasted time greater than 10 minutes possibly even up to an aborted flight.

      In other words, a false positive, if you actually believe the sensor, is going to require a real thorough search.

      If you don't believe the sensor, then you won't perform the full search, but then that raises the question: If you aren't going to treat your sensor as if you believe what it reports, what is the use of the sensor?

      Simple: just don't carry your BOARDING PASS to the RIFLE RANGE.

      Oh yeah, and don't touch your boarding pass with your hands.

      The whole point of this type of thing is to be sensitive enough so that it can detect the person who assembled a bomb and put it into his luggage and then picked up his boarding pass from the ticket agent, walked across the airport and handed that boarding pass to the gate attendant. It needs to be able to work even if the bad-guy took a shower after packing the bomb away and before touching the boarding pass.

    You've been though the perv-scan or the finger-rape, your carry on baggage has already been nuked, and you're at the boarding gate with only Sally Swipe-n-Smile between you and the 'plane.

    Then the machine goes "ping" and the siren goes off. What now? How does that play out?

    If it's a false positive (and it will be) then Sally asks you politely to step aside, and it's just another piece of minor inconvenience for the airline, and probably a missed flight and some more TSA probing for the traveller.

    But let's pretend for a second that it's a true positive - which is surely the only scenario that we're actually interested in. What then?

    Does Sally throw herself onto the passenger in slow motion, screaming "Nooooooo!" in order to save everyone else? And how does she know that this is the one time that it's a real threat, rather than the false ones that she's become used to, day after day?

    Really, how does Sally react to the real threat, and what will be the results of that reaction?

    Unsurprisingly, the ACLU did not want to take the case, seeing as how they are a staunch opponent of gun rights, and numerous civil rights attorneys I called said it would be pointless to sue, since apparently the courts have adopted the stance that you give implied cosent to both searches AND interrogations when you purchase a plane ticket.
