Airport Face Scanners Essentially WorthlessIt’s a boon to scriptwriters who need some phlebotinum, but in the real world face scanner technology isn’t making the grade:
Airport face scanners designed to verify travellers’ identity against their passport photographs are working at such a low level that they would be unable to tell the difference between Osama bin Laden and the actress Winona Ryder, it has been claimed.
In a leaked memo, an official says the machines have been recalibrated to an “unacceptable” level meaning travellers whose faces are shown to have only a 30 per cent likeness to their passport photographs can pass through.
The machines, undergoing trials at Manchester airport, have apparently been questioning so many passengers’ identities that they were creating huge queues.
Rob Jenkins, an expert in facial recognition at Glasgow University’s psychology department, said lowering the match level to 30 per cent would make the system almost worthless.

I don’t know about that guy on the right but the girl on the left is box office poison.
Somehow, in the middle of a war zone, U.S. forces manage to implement a quick and portable biometric scanning system (http://www.usatoday.com/news/world/iraq/2007-07-12-iraq-database_N.htm). Yet, it is apparently impossible to implement anything serious at airports…
Heck, even at Disney World, they use thumbprints to validate their tickets.
Yes, but everyone knows DHS is a Mickey Mouse operation.
It works in the war zone because the much smaller number users of the system have their biometric data collected beforehand. It would work at airports, too, if you first took the step of creating a biometric database on everyone in the US. Good luck with that project. And it wouldn’t work nearly as well because an algorithm distinguishing between 300 million people is much more prone to failure than distinguishing between 1500 people at an embassy.
From that USA today article about how it’s being implemented:
I live in one of the most rednecky areas of florida, and let me tell you, government agents driving around here trying to take eye scans of citizens would be met with, shall we say, a very…energetic…response.
Face scanning and comparing to a photo can’t work, because the number of false positives is guaranteed to be much higher than the number of actual threats. For as scared as we are, the number of terrorists trying to hijack planes is essentially zero. If you’re the TSA employee, and in your 3 years on the job the red flag has gone up 14,789 times, and it’s been not a terrorist 14,789 times, do you even blink when the red flag goes up ten minutes from now? Anyway, we’re spending way too much money on airplane security compared to other potential threats.
I haven’t been to Disney World in decades, so i’m not sure what they’re doing, but I’ll presume that they’re taking a fingerprint one day, matching it with the ticket, and comparing it with the fingerprint of the person using the ticket the next day, so that, say, people don’t buy multi-day tickets, go once, and resell the ticket. This is an easy way of making sure person A on monday is still person A on tuesday, but this has no relevance to airline security. If I fly on monday the airline doesn’t care who I am on tuesday, because I’m off the plane.
Metal detectors are serious, x-raying luggage is serious, the machine they put me through in ATL or RDU which blew puffs of air on me and looked for explosives is serious, and reinforcing cockpit doors is serious. The problem with airline security is that it’s Too serious now. We ask millions of people a year to take off their shoes because one numbnut one time tried, and failed, to use a shoe bomb. We don’t let you take on breast milk or shampoo because you and your three chemist friends might sneak into the bathroom, build a fume hood, run controlled reactions for several hours, build a detonator out of…I don’t know, toilet parts, and blow the plane up. That’s ridiculous.
