Facial Recognition Fails in Boston, Too
bryan writes "Only a few weeks after cameras were found to be ineffective in catching criminals in Tampa, FL, a test of a facial-recognition system in Boston's Logan airport also came up disappointing. The cameras which were given photos of employees to detect, were only successful in 153 out of 249 random tests over the past year (about 61%). The article did not say how many false positives the tests generated. The companies involved were Indentix and Visage."
As super-duper as high-tech is, I think even /.'ers would admit that its not a panacea (yet) for all our security ills. The very idea of having a computer capable of accurately identifying one face in thousands -- scanning from afar -- is far fetched. Despite billions in research we've yet to master voice recognition which is, comparatively, much easier to do.
Ah well, what's another few hundred million of tax payer's money shot. I'm sure it made some contractor rich.

I'm not sure I would call the failure of big-brother tech "disappointing".
They aren't at the stage yet where machines can recognize people based on gait and mannerism. Facial recognition is a best guess and still requires a human to be sure of the fact just like fingerprint systems.
Trolling is a art,
As with most biometric systems, this is only ever works reliably in a lab.
Remeber the fingerprint system that got fooled by gelatine-gummi's ?
I wonder when these dot-bomb ideas will stop popping back up, and more credible research will get the much needed funds.
There is only one thing that has ever been able to recognize the human face; other humans. (And we do a rather poor job of it too after 10 million years of evolution!!!)
Proof: Take your average ignorant North American, (like myself) and ask him to tell the difference between 3 different Asian individuals. There is a good chance that we would fail that test because we are not used to (or mentally trained to) spot the difference.

"The price good men pay for indifference to public affairs is to be ruled by evil men." ~Plato (427-347 BC)
A government test in 2002 found that face-recognition systems scored correct matches more than 90% of the time when used for such one-to-one identifications.
Once again, the false positives are not given. That is the number that really matters in a society where you can be held in prison indefinitely without a trial or access to a lawyer.
Oddly, I read the article (unusual for a Slashdotter) here and it seems to imply that these companies were marketing their products for the limited use of trying to catch people with forged identity documents. Rather than just having a Customs officer compare the photograph to the face next to that photograph, the software could chime in with "Yeah, that's her alright." It looks like the security people at Logan Airport deployed these products in bulk. I wonder whose bright idea it was to try and use these at randumb? Perhaps a zealous salesperson or an overenthusiastic security manager? I also noticed the company spokesperson sounded a bit "hedged" like the company is trying to state that "Gosh, this product was never meant to be USED the way this customer is using it." The part left unsaid by the spokesperson was, "We told them this wouldn't work..." On a side note, let's not even consider how abysmal this software must perform when terrorists are deliberately disguising their faces.
In principio erat Verbum.
They said 10 of the 19 hijackers went through Logan - so this system theorhetically would have caught 6 of them? Better than none
The 9/11 hijackers used their real names and real ID. If they'd been placed on a simple watch list of names then strcmp would have found them, not some highfalutin' face recognition system. It's not the technology here, but coordination between the three letter agencies that's needed.
John.
Okay, I admit it. I single-handedly foiled big brother's plan by marching around Logan with novelty glasses and a giant foam cowboy hat.
It quotes the Logan report saying, "the number of system-generated false positives was excessive."
May I direct you to the following quote, from a highly notable artificial intelligence program: Proof!
Computers hate us to their very bones. My computer has only crashed when I've been doing something important, like writing a term paper or surfing for porn. They're out to get us, all right.
