The iconoclastic Tim Worstall starts the ball rolling here, and refers us to Ben Goldacre’s Guardian column here: “But it’s not. The leak last week wasn’t because of unauthorised access, it couldn’t have been stopped with biometrics; it happened because of authorised access which was managed with a contemptible, cavalier incompetence. The damaging repercussions for 25 million people will not be ameliorated by biometrics.

So will biometrics prevent ID theft? Well, it might make it more difficult for you to prove your innocence. And once your fingerprints are stolen, they are harder to replace than your pin number. But here’s the final nail in the coffin. Your fingerprint data will be stored in your passport or ID card as a series of numbers, called the “minutiae template”. In the new biometric passport with its wireless chip, remember, all your data can be read and decrypted with a device near you, but not touching you.”

Ben Goldacre also has a piece here that refers to an academic paper enchantingly titled “Impact of Artificial “Gummy” Fingers on Fingerprint Systems” by Tsutomu Matsumoto, Hiroyuki Matsumoto, Koji Yamada, and Satoshi Hoshino of the University of Yokohama. “This paper reports that gummy fingers, namely artificial fingers that are easily made of cheap and readily available gelatin, were accepted by extremely high rates by 11 particular fingerprint devices with optical or capacitive sensors. We have used the molds, which we made by pressing our live fingers against them or by processing fingerprint images from prints on glass surfaces, etc. We describe how to make the molds, and then show that the gummy fingers, which are made with these molds, can fool the fingerprint devices.”
