Replacing Metal Detectors With Brain Scans
Zordak writes "CNN has up a story about several Israeli firms that want to replace metal detectors at airports with biometric readings. For example, with funding from TSA and DHS, 'WeCU ([creepily] pronounced "We See You") Technologies, employs a combination of infra-red technology, remote sensors and imagers, and flashing of subliminal images, such as a photo of Osama bin Laden. Developers say the combination of these technologies can detect a person's reaction to certain stimuli by reading body temperature, heart rate and respiration — signals a terrorist unwittingly emits before he plans to commit an attack.' Sensors may be embedded in the carpet, seats, and check-in screens. The stated goal is to read a passenger's 'intention' in a manner that is 'more fair, more effective and less expensive' than traditional profiling. But not to worry! WeCU's CEO says, 'We don't want you to feel that you are being interrogated.' And you may get through security in 20 to 30 seconds."
wonderful piece of technology known as the polygraph before..... don't polygraphs also rely (in part) on body temperature, heart rate and respiration?
I want peace on earth and goodwill toward man.
We are the United States Government! We don't do that sort of thing.
I have to wonder how they tested this to draw their conclusions about "how terrorists feel before boarding a plane." Grabbed a couple off the streets and offered them 80 virgins to take a survey or something?
I'm pretty sure the airport can generate anger,fear, and frustration in most people.
How good can this really be?
What about someone who is carrying a weapon without their knowledge? That won't show up on the scans. I could see the supplement current screening technologies if it ever is deployed, but not replace them.
Let's not even start about false positives....
Can it also detect replicants?

'We don't want you to feel that you are being interrogated.' Yeah that might interfere with your interrogation.
I can see it now...someone hacks the system and substitutes subliminal porn images for the bin Laden pictures. Talk about provoking a physiological reaction...
The NSA: The only part of the US government that actually listens.
Right now it is used to find terrorists, but this technology can be used in reverse. Flashing images of the president and the national flag, anyone don't respond positively get singled out... Such uses are very disturbing.

"It is possible today to hijack an aircraft using only five or six able-bodied passengers who are well-trained in Kung Fu fighting," he says. "There is no technology in place in airports to detect a threat like that."
Well, no. Not unless you start putting Ninjas on every plane. Everyone knows that Ninjas > Kung Fu fighting.
Apparently, Everybody was Kung Fu Fighting...
tl;dr WTF?
And how did they devise a control for this?
AFAIK, there's no biometric scans of the 9/11 terrorists, so it's just like the company is guessing anyway. For all we know, terrorists could be the only completely calm people going through security, as they're the only ones not worried about arriving at their destination late.
At some point, people will get so pissed off at getting poked, prodded, searched, scanned, monitored and tracked to see if they are terrorists, that they will wind up deciding that it is actually easier to become terrorists themselves.
This is my sig.
*Packs tinfoil hat*
Unless they couple this technology with the ability to read people's minds, then it's completely worthless.
What if random traveler A is thinking about terrorist activities in Mumbai and is afraid for their family right when they happen to walk through the little flashy thing (even if they don't know it)? The system would flag them as TERRORIST PROBABLY and they'll get arrested and cavity searched for no reason. Meanwhile the terrorist who focuses on bunnies and happy flowers and goes about his business will get through security just fine.
Even if I see it I wouldn't believe it... Just like The Riddler's machine in Batman Beyond - it just raises too many questions.
I think that's how they brain scan the TSA employees.
If I know I'm nothing but an elevated heartbeat away from being branded a suspected terrorist by airport security, well guess what? I'd probably have an elevated heartbeat.
Murphey's fighting Occam, and we're in the stands.
(1) This technology will not be reliable enough within the near future to prevent many false positives (as someone mentioned above). Which is unacceptable. Our legal standards abhor "fishing expeditions" by the authorities.
(2) We musn't just look at the potential good. There is also enormous potential for abuse. Probably enough to outweigh any good it might do.
My intention may be harmless but those who hid a bomb in my bag may have other ideas. How does scanning my brain help then?

Even presuming that one could reliably detect stress or heightened emotional states via this technology, what is rate of correlation between that and committing terrorist acts? I don't know about anybody else but I know alot of people who are terrified of flying and exhibit alot of stress in the airport. Enough false positives and this technology is not only ineffective but also a tremendous burden in price, personnel, and inconvenience.
I have no ill intentions, but I hate going anywhere unarmed. Maybe I could finally fly without having to give up my knife and sidearm.

..the plumber isn't worried, because he's going to be with his 70 virgins. I think it would be an ok addition, however - it is no replacement for the current security checks.
It's all fun and games till someone divides by 0. Then it's hilarious.
Is there a chance I might actually see an image of Goatse Guy while being tested? I wonder what kind of "stimulation" that would bring up.
Would these things detect that you're attempting to fart silently? Esp when you know that it will in all likelihood cause the person next to you chock to death? It could be considered a biological attack.
How do you know someone's normal heart and breathing rates? They're not seriously going to take an avg are they? Also, increased heart rate & breathing are common for people with high blood pressure, and/or overweight. So does than mean every American is a terrorist? Good job, people! Also, if people are stressing about generating a false positive, they will generate a false positive. Just a few thoughts.
and any one how shows any smarts does not get the job.
And someone will think, this guy... :-)
(The subconscious mind works in strange ways.)
It must have been something you assimilated. . . .
Airport security is a sham as is anyway. It's all just a show to make you feel safe. They'll, of course, have to detain, torture, and execute the odd innocent as a sign that the invisible force of knowing is working. Kind of like playing a "death lottery" every time you fly.
I am the penguin that codes in the night.
Seems to me that they'd be catching people that were carrying only legal items. It wouldn't be a stretch for an evildoer to put their toothpaste and mouthwash in someone else's carryon luggage intending to get it back later if the innocent got through security.
Of course, I don't know who you'd plant it on. The families with screaming babies and old ladies seem to be the only people who get randomly selected to get the truly invasive screenings.

Oh the tyranny of average... Just wait until they start singling out people for not fitting profile American 2.0, because they didn't recognize the last American Idol contestant on the subliminal. Think it's far fetched? Think again. In other, unrelated news, cattle mutilations are up.
#fuckbeta #iamslashdot #dicemustdie
Here's my question. How do they know about the biological responses of a terrorist about to commit an act? Surely they are just making educated guesses (therefore can lead to false positives). They can't really measure someone who's about to commit an act, right? Or whoever doing the experiment would have been blown off.
The only possible interpretation of any research whatever in the 'social sciences' is: some do, some don't
Frankly, about the only sinister thing about this is that there are people in officialdom who are so fundamentally brain-dead they actually believe the claims of whatever idiot is trying to sell this.
Even when interrogators have the time and money to hook people up to the most sensitive equipment available there is no technology that can determine to reasonable accuracy whether a person is lying in answer to a given question, nevermind their exact mindset or intentions in the next few hours.
Now we are supposed to believe that some gadget can automagically determine whether or not somebody wants to blow up a plane when they walk past it and are flashed a "subliminal image" of osama bin-laden?
I could go on about the sheer idiocy of assuming that somebody's reaction to a popular hate figure defines their politics or intentions. I could start about how peoples wildly varying mental states and physiologies make such simplistic measurements useless. But frankly it's not even worth deconstructing an idea this stupid in detail. Anybody dumb enough to believe in this fairy story clearly either suffers from paranoid psychosis or is so mentally deficient as to be beyond any form of rational argument.
EVERYBODY KNOWS that if some asshole tries ANYTHING on a plane, the only thing to do is for the passengers to immediately stomp the life out of the motherfucker, no ifs, no ands, no buts. Just take him apart.
EVERYBODY KNOWS that, including the terrorists. As a consequence, there is really no point to screening people at airports.
If people want to blow up a plane, it's a lot easier to book a flight, check your bags full of bombs that are hooked up to timers, and then let it rip. The security at the checkpoint is ludicrous, and the security for checked baggage is even worse. So, if you want to blow up a plane, it's not hard.
If you want to commadeer the plane a la 9/11, the passengers will take you out before you even get to the cabin. They know they have nothing to lose.
So, as a consequence, there is NO point in this idiotic security theatre. None whatsoever. And the smiling jackasses who come up with this Orwellian technology are vampiric leeches with their fingers up the butt of the reactionary militarists and an invertebrate Congress.
And all it means is that flying on an airplane is just that much more insulting and that much more irritating, and that much less worth the trouble.
RS
Shoes for Industry. Shoes for the Dead.
Crap. I seem to be exhibiting all the known signs of a terrorist.
Where do I turn myself in?
Seriously though, the security theatre in place does a great job of herding people into crowded areas where the air temp rises, and people get stressed out, resulting in all three of these so called terrorist signs. Without a slightly more relaxed general attitude, people have every reason to be stressed when they might be refused boarding due to some random TSA regulation, or have their property seized for no good reason (including that the screener feels like taking a nice new laptop home)...
[All Your Fish Are Belong To Us]
Are there really people out there who think we can achieve a perfectly safe world? Spending more and more money for ever smaller incremental gains in safety? Is the cost really worth it? Is giving up your rights really worth it?
At some point you have to stop and say look, there's an inherent danger in life. Your own body can turn against you. Are you willing to give up all your money and all your rights to feel safe? But what's left to be worth living if you've given everything up?
I cringe every time I hear about somebody dying in some unique way, because I know there are going to be laws that follow to ensure that never happens again. Unfortunately, those laws tend to be far more overreaching and subject to abuse in ways that are far beyond what incident initiated them.
People die. Dying is a part of life.

I think Kylie's 'Can't Get You Out Of My Head' would work pretty well today.
They say its only 20-30 seconds in security, until you realize that Bin Laden reminds you of you buddy's Moses costume last from Halloween when he kept drunkenly telling all the women to "part their legs like the Red Sea". Suddenly your subliminal responses swing the wrong direction and you end up being held in more traditional interrogation for hours to months in some dark hole halfway to Hell.
Common Sense isn't as Common as people think...
So, what if my reaction to an image of George W. Bush is worse than my reaction to Osama? I mean Bin Laden is indeed a leading terrorist etc, but he is hiding far away in Afghanistan, years after his deplorable act. At the same time George has been right here screwing with our lives every day...
Would I still pass security in 20-30 seconds?

You counter with Ninjas, then they counter with Pirates. You think the Ninja's will stand a chance against Kung-Fu Pirates? I shudder at the thought of what they will be stopped with.
Even if it were foolproof, what about a passenger who has some remotely controlled bomb for example planted on them? They would not even know. I don't think it so wise to eliminate the metal detector yet.
www.Migrainesoft.com - Computer giving you a headache? We can fix that!
Actually, let's do...
What many people don't realize is that detection procedures with very impressive-sounding statistical properties generally do horribly at catching rare events.
Imagine some very impressive numbers. Suppose that this procedure has 99.999% sensitivity -- it catches nearly every wannabe terrorist who tries to board a plane intending to do harm. And suppose it also has 99.999% specificity -- out of 100,000 innocent passengers, 99,999 will be correctly identified as innocent, and only 1 will be a false alarm. Sounds good, right?
Not really. In a given year, only a very small number of passengers are wannabe terrorists -- say, 10 per year. (That's probably high.) On the other hand, there are 1.6 billion air passengers per year (that may be a low estimate, since it's a 2000 number). So if this were implemented worldwide, then in a given year, we can assume that this profiling procedure will flag 160,010 people as terrorists. Only 6 x 10^-5 of those will be actual terrorists.
Of course, those hypothetical sensitivity and specificity numbers are unrealistically, ridiculously good. With more realistic numbers, the problem gets much worse. Even if the detection procedure is very sensitive and very specific -- and I doubt that it is -- the low base-rate of terrorism means that an enormous number of people will be falsely accused of being terrorists.

I'm pretty sure I could trigger a false positive almost every time. I have such a general dislike for humanity that even if I'm getting on a plane, I'd still love to see it plough into a building. Okay... So maybe that's not precisely a "false" positive, but just because I want the plane to turn into a ball of fire doesn't mean I intend to do it myself. I'm far too lazy for anything like that.

From the submitted story text... ...detect a person's reaction to certain stimuli by reading body temperature, heart rate and respiration â" signals a terrorist unwittingly emits before he plans to commit an attack...
And nervous ordinary folk who have fear of flying, but must fly to somewhere anyway because of job/family/whatever, don't exhibit these very same kinds of physiological responses???
Especially when these days we add fear of terrorist hijackings and security gestapos in airports on top of their already being afraid to fly in the first place.
With economies of scale, this will make CAT scan cheaper. So, instead of paying $1000 for a scan you can spend much less for a round trip ticket and get the scan from DHS!
That's it... if there was any question about where that "too far" mark may be, we can be sure they have gone well beyond that point.
Now they can screen for all sorts of things... "gay"? "pedophile"? Who else can we decide to hate and persecute?
If all this stuff could potentially save my son's life, I still say NO!!
Pause for a moment to let the gravity of that sink in. Now go back and realize that there is more chance of a drunk driver killing him than a "terrorist." Regardless of which may happen, it will always feel tragic and there is no way to effectively protect ourselves from everything. This crap has got to stop.

Do you believe that your average flyer today has the courage and determination to go up against a determined person wanting to damage or bring down the aircraft?
They would if everyone who boarded an airliner was issued a Louisville Slugger baseball bat as they entered the front door of the airplane and by law had to hold it for the entire duration of the flight. This would work as a wonderful deterrent for anyone who otherwise would be an obnoxious passenger. Everyone would be very polite to one another.
Yup, I'm sure they will have no shortage of test subjects and whenever they need more, they can go and round them up. However, no amount of test subjects can make a bad machine work.

"And you may get through security in 20 to 30 seconds."
Either that, or you get shot in 20 to 30 seconds.
But I think you will no be going anywhere since you can't function while on meth.
However, if properly run, is a better method of getting real terrorist or criminals.
Metal detectors may stop some people but Richard Reid has shown that they will use other methods that device detection will miss. However a criminal mind will be hard to mask so no matter what the criminal uses (ie 3-ring binder).
You can look at prisons and they banned virtually everything yet they have created interesting weapons from what we call "safe" things. It is not the device that makes the weapon but the mind of the criminal.

I really wonder how this or similar systems will respond to people who are living their own nerdy/geeky lives, or people from remote places of this planet, who are not proficient in the mainstream culture.
How will this system respond to people who have never seen the stimuli thrown at them?
A nerd/geek occupied with ham radio or assembly programming may have only accidentally seen images of Osama bin Ladin while rarely browsing non-technology sites or maybe while looking at newspapers at a kiosk while trying to find the magazine with the most recent GNU/Linux DVD. And bin Ladin may really mean nothing to a person from Zimbabwe, Madagascar, Siberia, Nunavut, Amazonia, Patagonia, or Antarctica.
The .45 Auto and .357 SIG are both good, but I'm sticking with the 10mm -- 180 grains at 1300 fps beats anything short or a .41 Magnum ballistics.
How did you come up with that figure of 1 in 1,000,000,000?
In Soviet Washington the swamp drains you.
The more fanatical Moslems don't believe images of the human form are that great an idea. So how is some bomb-carrying lack-wit from a village so far in the hinterlands that the town prostitute is a goat going to know what Osama looks like? And how is he going to react to a picture of him, except to think that the damned infidels are mocking his religion again?
Just wondering.
I've calculated my velocity with such exquisite precision that I have no idea where I am.
These things keep coming up, therefore I must keep repeating myself. Every time any sort of "screening" for terrorists comes up, I point out the problem of overfitting. This comes into play in two ways:
1) It's a simple mathematical fact that if you do not have a suitably large training set (i.e. *actual terrorists*) to study while developing your model, then your model is 100% horse crap, no matter how many anecdotes or pet theories you put behind it.
2) Even if you do have enough *actual terrorists* to study, there is no guarantee that your model actually predicts terrorists when applied to new subjects. It is more likely that your model is latching on to some coincidental pattern in your training data, then actually predicting anything. The problem gets worse as you add more parameters to your model. To reduce overfitting, you need a very large sample, and you need more samples to test your model after the fact. Even then, overfitting can still occur.
Fact: We *do not* have a large sample of actual terrorists that we can freely study for developing a model for predicting terrorist behavior.
Inescapable conclusion: This will result in a *huge number of false positives*.
Additional problem: The *actual terrorists* can learn your (flawed) model by performing their own tests on your system, and by choosing people who routinely get through your system, they can *increase their success rate*. This was proven in a paper a few years ago.
Oh well, here's to tons of wasteful spending that will inconvenience (and sometimes physically harm) honest people and increase the likelihood of successful terrorism!
Music speeds up when you yawn, but does not change pitch.
The test hinges on potential terrorists showing signs of stress and apprehension, and responding to subliminal visual queues. The test doesn't detect "intent", it detects "apprehension" and "emotional response".
So for the dedicated terrorist organization the remedy is simple: find people who are calm and collected before they commit an act of violence by nature or by indoctrination. People who are naturally relaxed before lapsing into violence exist and in a civillian environment they are called psychopaths. In a military environment they are often highly respected members of the special forces.
People can also be trained up to be calm before going into action, and religion is an especially good way of doing this. As is combat experience. When people are totally at peace with what they are going to do and what will happen to them as a result, they don't show up as anxious.
In addition you can train people to pass the test by first sending them through security without weapons, but with the firm intent to deceive. Those who are successful can be sent through with (allowed) plastic knives (or whatever) to see if they pass again. Then you send them through with a sealed bag and a phone and instructions that they will receive an signal on their mobile phone when they are to act (after passing through security of course so it doesn't necessarily show up). Everything risk-free and above-board, but as a terrorist organization you *do* get to find out the sort of fatalistic dupe who would be suitable for an operation. And when you finally mount your terror attack, it will work fabulously because all airport scanners have been replaced by "apprehension scans", which the people you are sending in can successfully negate.
Used alongside conventional scanners, the proposed scheme might, just might, be able to increase the detection rate. Which will produce generous amounts of false positives anyway since the number of terrorists amongst the thousands of passengers who fly each day is extremely low (how many hijackings do we get per week, eh?).
Sorry, but this scheme sounds idiotic to me.
Israel has determined that the best way to spy on the world is to be the country that produces all the spy equipment used by the rest of the world.
They've been involved in developing the CALEA wiretapping equipment used by the FBI - until the FBI shit a brick when they found Israelis selling wiretap info to drug gangs in Los Angeles. Factions of the FBI also have complained that Israeli employees of the companies involved had too much access to the systems. So I believe the Israeli companies were cut out of the loop. However, you also don't know who is involved in what - many US companies deploying this sort of thing, if you look close, have an Israeli on their Board of Directors or executive staff, or are subsidiaries of Israeli companies, or funded by Israeli investment companies.
Many of these Israeli companies in turn are funded by either the Mossad or the Israeli Defense Force under specific programs designed to finance high-tech startups with intelligence or military value. Do a Google on this subject and see for yourself.
This sort of tech would be just what Israel needs to basically spy on every human being going through an airport anywhere in the world. Depending on the software - which you can bloody well bet is NOT open source! - they will be able to identify and track specific people everywhere - whether they are "terrorists" or not.
As for the basic uses for which it is supposed to be designed, this is on a par with lie detection equipment - it's pseudoscience. The number of false positives will head to infinity.
And you thought metal detectors were bad!

doesn't a person who's nervous about flying emit the same bodily signals?
couldn't this technology also be misappropriated to force a person to unwittingly give up their sexual orientation?
Sounds like biometric discrimination to me.
They're using their grammar skills there.

Well, one day they should start to check whether travellers have genuine patriotic feelings towards the USA, if not, make them disappear. I'd say the unimaginable drop in travellers could persuade them finally that it isn't a good idea to produce ever increasingly humiliating checks.
As to the test at hand, I have a somewhat elevated blood pressure - always had -, I always am nervous when in contact with every kind of security people - I can't help it, I was a kid in a strongly communist country, some feelings can't be easily eradicated -, also on 9/10 times when flying I have to really hurry on airports - since I prefer quick connections to waiting many hours at airport lounges. Combine all of these and I'll be an easy target.
As always, it's not the false positives in themselves that bother me - although I know pretty well how most of the biometric systems work and fail - but the delays and inconveniences such false picks can cause you, from lost flights and luggages to time spent explaining things you shouldn't need to, and so on.
And, at the same time, most of the terrorists will just as easily pass security as they've always have. From the top of my head, let's just say there could be 1 terrorist out of 1million passangers. Knowing the average true positive recognition rates, around 10000 passangers could easily be falsely picked out, while that one terrorist could easily slip through.
I am putting myself to the fullest possible use, which is all I can think that any conscious entity can ever hope to do.
So wait... you want me to trust the TSA employee (who gets suspicious about the fact that I have two cellphones with me) to accurately read a machine that picks up biometrics? Give me a fucking break.
"We don't want you to feel like you are being interrogated." Yea and the nazi's didn't want the jews to feel prosecuted either.

They don't have "every right". In fact, they don't have "rights" at all. What they have is authority, and that authority is questionable.
TSA was given too much arbitrary authority that is arguably unconstitutional.
