Security Checkpoints Predict What You Will Do
An anonymous reader writes "New security check points in 2020 will look just like something out of the futuristic movie, The Minority Report. The idea of the new checkpoints will allow high traffic to pass through just as you were walking at a normal pace. No more waving a wand to get through checkpoints — the new checkpoint can detect if you have plans to set off a bomb before you even enter the building."
Trials will be deemed unnecessary in 2025.

In other words, anyone who looks Islamic will be stopped and searched as will a few others chosen at random.

78% accurate in a controlled setting is nothing to be proud of. I'll grant the fact that they're still in the early research stages, as they say, but I'd need to see an accuracy rate of over 99% in a real world application for me to consider it a valid option. Otherwise there will be far too many false positives for it to be useful in a high-traffic situation.
I'll leave it to other people to point out everything else wrong with this kind of system.
Murphey's fighting Occam, and we're in the stands.
So, when I walk into the airport, in December, at minus twenty, in shorts, nad my skin temperature is about ten degrees colder than the average, and my heart rate is about 20 points higher than the average, and I'm not sweating, and there's snow in my boot, I'm going to be intercepted every time -- for being different. Great.
But really, this time I read the article, and welcome to the same stupid problems for the same stupid solutions. The system is basically a remote polygraph. So you can walk at full speed while it assesses you. So we'll have longer corridors, but the exercise will be nice.
Of course the tests get to measure people's personal intents. Great. So anwser two questions. . .
- do you think trained criminals can learn to pass polygraphs? C.E.O.'s don't seem to have much trouble. Frame of mind and all that.
- so crime will once again shift back to the days of slipping something into someone else's bags. that someone else has no idea that they're carrying a bomb. The criminal may set off the system, but he's got no evidence on him anymore. So what exactly are you going to find? And which plane are you going to check? Even the criminal may not know which random passenger was marked.
This is why security never learns. Criminals have an arsenal of techniques from thousands of years of history. And those criminals get to pick what they want to use today. And those criminals have a darn good reward for picking the correct one. On the other hand, security personnel, and I include this system's designers, try to solve the current problem, and ofter forget the old problems. The criminals know exactly which systems are presently in place, as well as any routines being used by personnel.
So once again, we've managed to stop the dumb criminal with nothing to gain, and amused, or worse challenged, the intelligent criminal with lots to gain.
Sounds pretty hokey to me... As a frequent air traveler, give me the old fashioned pat down search with full baggage inspection - in fact I felt safest after 9/11 when they did random searches at the gate too - I have seen more than one person lead away from a gate in handcuffs after a random gate search turned up illegal drugs or other such nonsense. So the fact that they made it through the gate in the first place points out the fallibility of the current process. IMHO we need MORE hands on security not less, more sniffers and x-ray machines - I can easily factor in a longer wait at the airport, the peace of mind is worth it to me...
The FAST system detects physiological signs of stress. In testing it detected "hostile intent" in volunteers. The obvious question is how can volunteers have valid hostile intent? You can't test deception with fake deception. The generalizability of physiological response to stressors is a basic tenet of physiological psychology (the folks who brought you FAST's grand dad, the polygraph).
The volunteers knew they were volunteers in a study and in no danger. In practice, this device will trigger on every person who is nervous about flying, because the physiological markers for stress are the same regardless of the reason. There will be many, many more of those than with 'hostile intent'. The test study was unable to have adequate control (real, naive persons) to prove its claim.
Most people can learn simple biofeedback techniques to control physiological reactions to some degree. Those with hostile intent don't need to get very good at it, they just need to be able to control it better than an untrained person with a fear of flying.
FAST isn't supposed to work. Its owners know it can't. It's just supposed to be believable enough to convince the public that it could catch bad guys to increase public confidence, and to convince the government that further funding is warranted.
Stick the designers in it and ask them if it can tell hostile intent from fear of flying (and base GAO investigation of the program upon the result, to make it more salient). They'll say yes. Either it'll trigger and show them to be lying, or it won't and so it doesn't work.

Firstly, they don't say the false positive rate , they only say the true positive rate. By now many poster here will have picked that up. Even at 1% false positive , pass 10000 person thru the check point, 100 false positive, yada yada law of great number etc...
Secondly It only does detect external signs of nervousness at best and nothing else. Such sign of nervousness MIGHT be displayed by people with malevolent intent, but certainly not only by them. Consider where such detector might be implanted : courtroom, IRS, FBI buildings, airports before boarding. A lot of place where people WILL be more often than not nervous. And what will happens ? Terrorist or any other mal intended smart persons will get an additional training : 1) meditate to lower all sign of nervousness 2) take a nyquil or whatever calm you down.
Thirdly, as the various western governments seem to go toward more and more security of that type, TV camera, drone and whatnot, I have long stopped fearing terrorist (and I barely missed getting in a bomb blast in Paris metro by a few dozen minutes...). Nowadays I fear the police and the governement and their big-brotherisation more than not. I fear that the time for the third box (the munition one) will come way sooner than I ever expected in my dystopian nightmare.

No, we'll only know what they think they want.

So basically what this article is really saying is, that by 2020 the West's gradual transition to total fascism will be near completion.
i would assume accuracy of mal intent detection only refers to false negatives and true positives (so 22% would be the fraction of false negatives, rather than false positives), it says nothing of the false positives (or true negatives, but they are not of much interest) which could be anything if no numbers are otherwise provided
Suppose I have to go to the bathroom and look nervous like I won't make it time? I'll probably set off the scanner as a suspected terrorist.
I'm afraid so. Wanting to get to a smoking area for a long overdue cigarette would be another good example (from my last encounter with DHS on entry to the US).
We all seem to have figured out that this system is a joke, so I won't address that.
The bigger problem is that the DHS really thinks something like this kind of system will work. We've seen several different screening systems, fingerprinting systems, etc, and they all share the same "whiz-bang technology" attribute. That is that somewhere, there's some great piece of hardware, software, or black box that's going to save us from "the terrorists" Real Soon Now. I guess I'm more than a little skeptical of this approach to the problem.
I don't know enough about the problem to know what the solution is (maybe just human operatives). But I do know enough about "whiz-bang" technology to know that it's snake oil.

(a) You can't put a bomb into anyones bag that can drive a plane into a building.
(b) I dare you to even try approaching another persons bag in an airport. People are paranoid about their luggage, and if anything it would be far harder to do this than to get something through security today!
Who says a terrorist has to want to fly a plane into a building? I imagine you could spread terror pretty effectively if you started salting baggages with bombs...
They want to have a lot of attention. If that means sleeping with you to get it, they do that. If you're willing to give them the attention they want without them having to sleep with you, they're all about that, too. That's why the friendzone sucks.
What fraction of the remaining 22% can we expect to be false positives?
Those can be justified away. It's the false negatives that folks will (ahem) have a hard time living with.
Seriously now, isn't todays smart terrorist working on "projects" that don't involve airports, airlines, airplanes, and going through an airport security checkpoint?

> For those who slept through Modern History class, I'll tell: religion. Specifically Muslims.
> They are the most likely group to set off a bomb on an airplane or hijack it. We can pretend that's not the case (and continue with the current "security theatre" at airports) in order to protect the delicate sensibilities of the PC crowd, but that doesn't change facts.
Let's assume for the sake of argument that you are more than correct and ONLY muslims will ever hijack or blow up an airplane. How do you propose we do this security checkpoint thing? "Hello good sir, what is your religion? If you are a muslim you have to go to that checkpoint there but the good god-fearing christians can skip it." I doubt having to lie to airport personel is going to stop someone who plans to kill dozens of people. Are you seriously suggesting that all muslims can be recognized on sight and that it is impossible for, let's say, a white woman to be a muslim?
What about people who have Autism or other disorders that cause them to express emotion differently? Are you going to lock me up just because I don't seem like a regular Joe Sixpack?
It looks like we need to update Pastor Niemoeller's famous poem. First they came from the Muslims...
Here are a few other conclusions from a non-PC but apparently somewhat more objective observer.
Probably the most violent recent religion looking over its history is Christianity. Should we detain all Christians? I bet that'll go down well in the US.
Actually, speaking of the US, they are the only nation ever to have actually used a weapon of mass destruction at a cost of numerous civilian lives, and they have repeatedly demonstrated their willingness to go to war other than to protect themselves from an immediate physical threat. Maybe the rest of the world should just nuke the whole US and be done with them?
Then again, the administration of any country that had WMDs could lose the plot and use them based on such dubious arguments, and any administration that has been in power for more than a short time and retains the option apparently has a willingness to consider using WMDs. Maybe it would be better for all of us if they just turned on each other to remove the threat against everyone else?
I'll stop there, because I've pretty much killed the entire world in only three steps by applying the kind of tragic, fear-driven thinking exhibited by the parent post. But I truly hope that 2009 offers us more than a binary choice between PC security theatre and the kind of indiscriminate fear-mongering we see here.
If you disagree, post your argument. (-1, Overrated) isn't your personal censorship tool for views you don't like.
I take it you've never been the guy they stopped by mistake. Being questioned and searched under such circumstances is not a trivial experience. It can be deeply unpleasant, and for some people it can leave mental scars that take a very long time to heal.

If she wanted a fat cock in her pussy, would she tell you? Yeah. Your anecdote excludes families that aren't into inbreeding.
Actually, she did tell him that, but in a typical fashion she said it in a round-about way, and he plain old didn't get it.
From his own post:
My sister says her favorite objects are [...] anatomy labs
Exactly what do you think is IN an "anatomy lab"? I'll give you a clue- the term "lab" doesn't necessarily mean a building & most likely is not an abbreviation of "Laboratory". If you conduct an "Anatomy Lab" it could mean doing anything related to examining, or performing experiments involving, anatomy.
"Lab" could also be an abbrevation for "Labia".
Dude, your sister is a Lesbian Slut.
According to the article all the much vaunted device does is measure heart-rate, blink rate, direction of gaze, perspiration level. All somatic quantities linked to anxiety levels. Nothing else.
And there's the rub. You can't catch someone who's calm and at peace with what he's about to do. Now that is a state of mind. Does "religious fanatic on a righteous mission" ring a bell? They have high levels of anxiety do they?
Or someone with naturally low anxiety levels who has been trained to commit violence and is at ease with that? Or someone who is able to take his mind off something? Or even someone who has been sedated?
This sort of monitoring might get an 80% success rate on ordinary Americans who are asked to carry an incriminating device through a checkpoint, but it was never tested with professional criminals. Like pick-pockets. Or fraudsters. Or even politicians for that matter.
That's why this scanner seems to be a bit useless against pre-meditated acts of terrorism committed by dedicated terrorists. It may have some success against people who are planning to spray grafitti on the wall of the office loo though. Nice going to counter a high-impact threat.
How about everyone comes through quickly - person by person - enters a bomb-proof enclosure, and is subjected to measures that would set off about 99% of bombs for premature detonation.
Maybe every 1 in 1,000,000 times you might get a *whoomph* followed by the need for a clean-up crew and a dust-bin, while renders the room unavailable for a time and everyone else has to go through the other enclosures, but it'd still be faster and more effective than the current methods :-)
