UK airports to trial face scan passport checks The UK Border Agency hopes to conduct trials of automated passport-check gates at UK airports this summer. The gates would use computer software to compare a traveller's face with the information stored in new biometric passports, removing the need for human staff. "Britain's border security is now amongst the toughest in the …
There's a class of computer that's especially good at face recognition, it has a massively parallel recognition engine and can match faces even despite differing expressions, lighting conditions and many other real world variables.
It's call a human brain.
Lets be honest about these biometric things, they don't recognise faces they recognize stuff like the estimated distance between the pupils of the eyes, or the ration of tip of nose to eye line to ear separation. All are rough estimates from a photo that a computer has no way of really 'seeing' and all are less able to cope with real world things than one of those massive super computers we call a borders officer.
It's a sales trick to call it 'face' recognition, same with fingerprints, retinas etc. all estimates and subsets.
At the rate things are going, illegal people-traffickers are going to be a viable alternative. Sure, you might spend 12 hours crammed into an uncomfortable position, get fleeced for all your money and be pushed around and threatened by the thugs who run the scam.
But if you go by air, you've got the flight to contend with on top of all that.
Yeah, it's so great that it gets bored if you ask it to spend its entire working life looking at faces. FAR better to let a dumb machine whittle the dataset down to manageable proportions and then let the human spend more time on those. Of course, you don't actually reduce your staffing requirements that way, but you probably do produce a better system.
For a country under constant threat from Bad Guys trying to sneak in with false passports, the improved security might justify the cost of the system. Does anyone know of such a country?
Reading this simply reinforces that people who make the rules don't have to live by them.
If any of the UKBA people who are thinking about this were to regularly travel into either Heathrow or Gatwick from outside the UK, they would know that Iris (the predecessor to any face recognition systems) is useless - often it is not working and when it does its slower than the normal passport control.
In comparison to the Privium system in Holland - Iris is very bad and Iris is not by any stretch of the imagination cost effective. At least for Privium you pay and get something worthwhile - includes express security screening.
So would not the money on a face recognition scheme be better put to improving Iris or its next version?
Another point comes to mind, enrolling people on the new face systems will be a huge task (new passports, enrolment... the list goes on) given how often most people regularly travel and renew passports.
So at what point would there be enough people enrolled to make it financially viable/cost effective, relative to border officers?
Someone's having a Toffee Crisp, at tax payers expense!
ps I have a fun rule for Iris: One person through Iris is equivalent to five people in the normal passport queue. So when walking towards it, I do the maths quickly and I always get through quicker in the passport queue! And I am enrolled on Iris - sad but true.
That's a concern for me as well. I trust a person to recognise me as the same guy as in the photo but with a shaved head - or who has changed his beard a bit (fun to play with sometimes). But a machine? It's bad enough that passport or any ID photos always make me look like a thug or a probable terrorist. I would certainly be more comfortable with a person who can recognise my innate charm (ok harmlessness).
I assume that a person would always review a machine decision but this might not mean much if that person is poorly trained or inexperienced and has decided that relying on (blaming) the machine is a safer bet re job security.
If the machines (as in RoTM) wore pants they would be wetting them with excitement over the possibility of taking control of travel chokepoints.
The (unmanned) black helicopter because that's an airline I don't want to fly.

Reminds me of a story I read many years ago of experiments with a tank recognition system for the army ... basically they "taught" a neural net to distinguish between photos taken of salisbury plain during some tank exercises with the same views taken the next day when the tanks were gone .... results were impressive and duly demonstrated ... however subsequent sets of photos were much less successfull. Eventually after lots of head scratching the designers came to the conclusion that the neural net hadn't learnt to detect tanks but instead coudl distinguish between Salisbury plain on a sunny day and Salisbury plain on a cloudy day!
""All new UK passports issued since 2006 contain facial biometric data."
A photo then?"
You may joke, but yes. The facial biometric is otherwise known as a photograph, digitally stored. More seriously this is one of the mis-truths (ie: Out and out lies) that ministers have been getting away with about ID cards. Several times on Radio 4 news I have heard government ministers saying that we may as well have ID cards because we're going to have to have biometric passports soon anyway. They somehow forget to mention that the biometric is a photo on a chip, which we already have.
Iris is useless, and slower than normal passport control?
B*lls. I've been using it for ages at various airports and it's always worked fine - the only glitch I've had is that I sometimes have to bend over. As noone else seems to use it it means you can bypass all of the queues - but of course this advantage would be lost if everyone had to use it.
The only reason passport control (without the queues) is so quick is because there is so little checking of UK passports happening, just a cursory glance at the picture. If we can take the same or a little more time to have a true identity check then surely that's a good thing.
My boss had his passport and driving licence stolen while abroad recently. He got a temporary passport from the British embassy where he was and flew back to UK. When he got back, he had no other ID than the temporary passport and was stopped by immigration. Luckily for him when he flew abroad last year he decided just for fun to register on the Iris system, and so they were able to use that to confirm his identity.
Since returning my boss has applied for a replacement photo driving licence and a new passport. The first set of photos he had taken were accepted for the licence but rejected for the passport, as were 3 subsequent sets, the 5th set finally being accepted.
I don't know if the people at the passport agency have shares in these photo-me booth companies but it took 3 sets of photos for my niece to get hers accepted for her passport.
