Lie Detectors to be Used for Airline Security
swimgeek writes "A new walk-through airport lie detector being made in Israel may prove to be the toughest challenge yet for potential hijackers or drugs smugglers. The product has been tested in Russia and should be commercialized soon. The software in the detector picks up uncontrollable tremors in the voice that give away liars or those with something to hide, say its designers. Passengers that fail the test are then required to undergo further questioning or even search."
I can't wait until I have to take a lie detector test before boarding a plane. I'm really getting sick of all these invasive security measures. I'm damn glad I won't have to hop on planes for my job.
If only taking a ship was a valid alternative for travelling overseas.
for innocent passengers as well, who, when faced with M-16 toting guys can't avoid an "uncontrollable tremor" in their voice.
No mention of the false positive rate on this. If just 1 in a million passenger is a terrorist, and given the number of passenger flights per year without bombings on US planes it has got to be way up there, the false positive rate it going to need to be way WAY down there.
A "Lie Detector" is a fantasy. Machines can detect physiological clues to nervousness, and that's it. http://en.wikipedia.org/wiki/Aldrich_Ames> Aldrich Ames passed his polygraph exams for years, while he was getting every US agent in Russia killed.
Depending on fantasies like "lie detectors" distracts law enforcement from practicing solid investigation.

Sounds like sufferers of spasmodic dysphonia, such as NPR's Diane Rehm are going to have a hell of a time at airports in the near future...

What about the poor schmuck just excited about going off to visit his mistress? Or his girlfriend, knowing he's about to get his first action in 9 months? Or any member of Congress?
I am pretty sick and tired of these jerkwads coming out with all of this technology that is supposed to protect us from somebody who has nothing better to do all day long than figure out ways to hurt us. And stick me with billions of dollars in expenses for a technology that may or may not catch somebody other than the occasional innocent git or two-bit martyr wanna be. Does it work? "Sorry, for national security reasons we can't tell you how many bad guys we caught or how many innocent guys to whom we gave a cavity probe".
Money isn't the root of all evil anybody who votes for any incumbent is.
If the g'vt kept the data on you that google does you'd better believe you'd be calling it "doing evil"
Voice analyzers and polygraphs (the so-called "lie detector") are frauds. They have both been scientifically proven again and again to be unreliable, with lots of false positives and false negatives, which is why they aren't admissible in court.
The only value to either technology is to scare and threaten. If the person being questioned believes that they work, they are less likely to lie or more likely to admit a lie.
Aldrich Ames, a mole in the CIA, passed a polygraph many, many times, as did lots of others.
Since voice analyzers and polygraph examiners make a shitload of money, and they compete with each other, they are great for pointing out the flaws in each other's devices since the other technology threatens their gravy train.
It's fraud, plain and simple. Flip a coin instead. It's more likely to be accurate than a voice analyzer or polygraph.
Then whomever gets the "glory" of murdering innocent civilians has one additional step in the training camp: learning how to calmly lie into the microphone. We don't pack the explosives in his bag until he can pass 10 times out of 10.
I'd much prefer returning to pre-1972 rules where the airlines could decide if you could bring a loaded firearm onto the plane. Those airlines that allowed it would get my business, and the free market would take care of the problem.

Pistol caliber is like religion: everyone has their favourite, and theirs is the only right choice.
I'm so glad that this new airline security will protect my rights as I surf the 'Net.
If there's a hot female security guard on duty, I'm gonna SO lie so I'll get searched by her.
Of course, while she might be asking the questions, you might get lucky and run into her huge Neanderthal compatriot that is manning the strip search station.So how many people will get searched as terrorists because their voice is shaky because they're cheating on their wife, didn't tell their parents they were going to costa rica with their friends, or told their employer they were going to a family reunion? Not everyone with "something to hide" is a lawbreaker.
Lie detectors are also used in Kansas. I am surprized they don't use the good old medieval torture techniques to find witches.
Even for friggin' nervous.

As me types in 'whimper' as the security word for this post - I wonder.

It's not ever going to happen again in any of our lifetimes. The terrorists burned that plan from ever working again because the pilots and people on the plane know that they're dead either way, so there's no reason not to resist. If they have a bomb, no difference. Dead when the bomb goes off or when the airliner hits whatever they're aiming at. No one on the plane has anything to lose. You can't control people with nothing to lose.
The 10-15 minutes multiplied by the millions of people who fly each day, the money for all the extra security...it's all meaningless. We're wasting millions of man-hours and millions of dollars to try and stop something that's not ever going to happen until a new generation comes along with "don't resist" drilled into their heads so a hundred of them just sit there like sheep and let five guys drive them into a wall.
But you can bet the terrorists know the things we're missing. That's where the next one will come from. Somewhere we're not expecting. And Condi Rice will be on TV going, "Who could have guessed they would use..." whatever it was. A little success for them goes a long way. We'll tie ourselves in knots and exhaust our treasury fighting phantoms. We'll over-react, like usual, and end up making more enemies than we started with while expending billions to little or no effect in the process.
All because of people like you.

The only worse thing I can imagine than the farse that is American airport security, is the possibility that some day they might actually successfully implement true security. I thought society was taking a step forward since you no longer need papers to travel inside Russia, or passports to go between France and Germany. I dread travelling now, because it offends me to have to take off my shoes and belt at the airport to maintain the illusion of security. But how much worse would it be when they confiscate my laptop because I could make an explosive from the battery in about three seconds? Or when I'm detained indefinitely because I'm a 20-something travelling alone, and I happen to be carrying a Quoran for some leisure reading.
In my life, terror doesn't come from desperate fundamentalists. Terror is the government trying to control every aspect of the way I live and the way I think. I can only hope that it's not too late to undo the damage. Vote while you still can! And pray, if you're into that sort of thing.
Ever wonder why we don't see any of these?
- Glasses frames with sharpened ends
- Suitcase handles with sharpened ends (pull them all the way out of the suitcase and you have a gigantic shank)
- A sharp plastic credit-card size object
- Some kind of chemical disguised as a useful medication (e.g. Tylenol) that ignites when it reacts with beer or soda or laptop batteries or something
- A car bomb in the pickup/dropoff area
And the list goes on.I make websites and stuff. Buy one.
The net tightens ...
I hope people keep in mind that terrorism kills fewer people than traffic accidents, lifestyle diseases, or regular crime (one of these alone suffices).
The way I see it, many of the prevention measures that have been taken only increase the effect that terrorism has on American society.
Please correct me if I got my facts wrong.
Great idea. Unfortunately that's not so easy
Great. Them the terrorists don't actually have to enter the plain, they just have to hack into it. However, I guess it's a great way to reduce cost for the airlines, and security would be a great excuse to make the passengers accept it
But the computers must be accessible somehow. After all, it's not uncommon that there are problems either on the plain or on the destination airport, and the plane must be redirected to another airport. And as long as there's an interface for that, there's a possibility that terrorists will be able to use it, some way or another.
And in case of an emergency (or just bad weather), you cannot redirect it to another airport, or even just tell it to wait until the runway is clear. Well, bad luck for the passengers
At that point you won't have any terrorist attack anymore because no sane person would fly in such a plane. Ok, that would probably be good for the environment
Which means that you would still need security checks anyway. Unless you think blowing up a plane is not much of a problem.
Unless they manage to change the programming before the plane even starts (in which case, after the plane took off, your scenario means there's no way to stop that program, except by shooting the plane).
See above. And as I already said, this also means you can't get it somewhere to safely land when there's a problem.
Of course. Which means, they'll just instead threaten to blow up the plane if they don't get what they want. Or maybe just kill all passengers (shooting a hole into one window after sabotaging the oxygen mask system should be enough for that, or they just use some poison gas; OTOH killing the passengers one-by-one might be more effective from the terrorist's view).
But again, even if that would make the airplanes completely terror-safe, I wouldn't get onto such a plane. The probability of a plane having problems is much higher than the probability of a plane being highjacked. Therefore I'd prefer a plane where I have a good chance to survive simple problems than a plane where I'm completely safe from terror attacks, but every unforseen problem will cause a likely desaster.
Unless you manage to build an AI which is at least as reliable as a normal pilot even in unexpected situations, I'm not going to fly on a plane which cannot be controlled by humans in any way. And even if you manage to build such an AI, it will have to rely on outside information for even such simple things as avoiding a thunderstorm or waiting for the runway to be clear.
The Tao of math: The numbers you can count are not the real numbers.
What a stupid concept, for a number of reasons.
Firstly, this kind of thing is based on the assumption that even a 'bad guy' will somehow feel bad about what their are about to do, and there will feel under emotional stress. Two of the most dangerous kinds of persons, psychopaths and suicide terrorists, are not likely to to fall into this category. Psychopaths don't care, simply, they will lie or contemplate atrocities like normal people would think about buying a bottle of milk. And a person who has decided to die has overcome the fear; it is a wellknown phenomenon that a person who wants to commit suicide often enters a phase of perfect calm and contentment when the decision has been made.
Secondly, as others point out, a lot of people feel very bad about small transgressions. I remember one lady who felt very nervous because she had bought 1 small bottle of alcohol over the limit and was afraid to get caught. So are we now going to catch all those who are under a bit of strain, but let through the really dangerous ones?
Thridly, wouldn't it perfectly possible to subvert the equipment - perhaps simply by eating Valium or similar?
Very interesting post, thank you.
Just a few comments:
I said in my post, I would not want the US to try to implement a security process similar to that used in Israel. I have a few reasons for that, which I didn't get into in my (already long) post.
First, as you said, there's no way it could be done without someone screaming "abuse" and filing a lawsuit claiming their civil rights were violated. As irritating as such things often are (and they are often crap), I think that is one of the best things the US has going for it, and I wouldn't want there to be any incentive to stop citizens from screaming about their rights and suing the government. Too much has already been taken away in the name of the Wars on Drugs and Terror.
Second, it's not necessary. There is a lot of anger at the US, but nothing like the scale of the anger at Israel, and most of the anger directed our way is actually earned. We can defuse it with time and rational foreign policy. IMO, Israel could defuse some of its troubles, also, but certainly not all, not without just handing over the Holy Land. The scale of the attacks directed against Israel dwarfs the scale of the attacks against the US, even on an absolute basis (though the 9/11 attackers managed to find a huge force multiplier, making that attack much more effective). When compared against the sizes of the countries/populations/economies, the only reasonable conclusion is that the US is equipped to absorb vastly more damage than Israel is. It would take a terrorist effort 1000 times more powerful to match the effect of anti-Israeli terrorism. Therefore, measures which make sense for Israel don't make sense for us.
Another reason it's unnecessary (I know lots of people won't like my first, "we can take it" reason) is because airports are no longer a good target. The post-9/11 security measures that *mattered* were: barring the cockpit door and increasing the number of air marshals. And the effect of those pales almost to insignificance next to another anti-hijacking development: Passengers now know that they should not be passive, because being passive will get them killed. That knowledge on the part of the passengers changes everything. Prior to 9/11, the nature of hijackings was different, and the smartest thing the passengers could do was sit still and obey orders. Now, the best thing to do is to rush the hijackers en masse. The 9/11 hijackers (or the planners, anyway) knew that the same attack would probably not work again, which was one reason they tried to make their four-plane attack simultaneous. Flight 93 was in the air long enough for the information about the new reality of hijacking to get to the passengers, and that's why those hijackers did not succeed. The passengers on Flight 93 couldn't save themselves, but they could make sure no one else was killed, and they did. Had they been a little luckier, they might have saved themselves, too.
Your points about the scale issues in the US are good, and ones I hadn't considered as clearly as you spelled them out.
Regarding the motivations of terrorists, I think you overplay the role of sex. There are plenty of perfectly normal western boys and girls who don't fool around as teenagers, and many even who don't have sex before marriage. Some because they're just too shy and awkward, but many because they believe it's better to wait, for religious or other reasons. This isn't to say that it doesn't have a role, but the point it that it's completely inadequate to motivate suicide bombers.
I think it's important to put that into proper perspective because I think it's too convenient a motivation, especially from people who would like to belittle the bombers and their motives. It's a motivation that both the religious westerners and the anti-religious westerners can grab onto, for different reasons, to look down on the bombers, considering them to be inferior people. Religious people can look down on them for being too weak to control their own urges, wh
