Future Cell Phone Knows You By Your Walk

jangobongo writes "Researchers at the VTT Technical Research Centre of Finland have come up with a unique way to secure your cell phone if it should get lost or stolen: 'Gait code'. Motion sensors in the phone would monitor the walking pattern (or gait) of whoever is in possession of the phone, and if the 'gait' doesn't match a pre-established biometric the phone would require a password to operate. The prototype cell phone correctly identified when it was being carried by someone other than its owner 98% of the time. The research team points out (powerpoint document) that this method could also work for PDAs, laptops, USB tokens, smart cards, wallets, suitcases, and guns."

Better biometric than fingerprints?

[ThinkingInBinary]

This seems like a better choice of biometric than most, because unlike a finger, it can't be cut off or "cloned" using gelatin or another way of transferring the fingerprint. Now, it might be possible to invent a "bug" that records someone's gait and feeds it to a set of servo motors that convince the phone you're them, but that's beyond what most people's resources and significantly harder than picking up a latent fingerprint.
