Human Ear Could Be Next Biometric System

narramissic writes "A team of researchers at the University of Southampton, UK, has received funding from the UK's Engineering and Physical Sciences Research Council to learn whether otoacoustic emissions (OAE), the ear-generated sounds that emanate from within the spiral-shaped cochlea in the inner ear, can be used as a viable biometric technology like fingerprints and IRIS recognition. According to a report in New Scientist, someday instead of asking for passwords or pin numbers, a call center or bank would simply use a device on their telephone to produce a brief series of clicks in the recipient's ear to confirm the person is who they say they are." Try faking that with gummy bears.

Biometrics are great

You're exactly missing the point - any self-respecting system must expect fraudulent impersonation.

We can all present ourselves to Slashdot as Cmdr Taco, but come password time most of us would be thwarted. If the password went away in favor of a fingerprint (or earprint), as soon as somebody lifts it and posts it, we can all be Cmdr Taco. Until he changes his fingerprints.

But if his fingerprints were just a substitute nickname/login id, even after they are posted online we'd still have to crack the secret to convince the system we're the real enchilada.

FFS.

So, let me get this straight:

We are poised to make the same idiotic "Hey guys! Let's use biometrics for authentication!" mistake that we've made all the other times.

So, you can test the structure of somebody's ear by clicking at it and recording the result. Does this mean that you can infer the structure of someone's ear just by clicking at them and recording the result, thus allowing you to, with a dash of DSP, fake their ear structure on future tests? I'd want to be Very sure that that wasn't possible. A system where you can get somebody's Super Secret Biometric Secure Security ID just by calling them up and making funny noises would be even worse than the issues with fingerprints as authentication methods.

Re:Gummy bear in my ear!

[Red Flayer]

It won't come out! STICKY!!! Thanks timothy.

Use a straightened fishhook, the barb will make the gummy bear easy to remove. Just be sure to wait until the gummy bear is warm and soft. And insert the hook very gently. And stick the hook through a cork first, to limit the depth it can penetrate -- measure by sticking the hook into the ear until it hits the gummy bear, then add 1/4 inch (about 1/2 cm). THIS IS VERY IMPORTANT. The length of hook sticking out of the cork should be distance to gummy bear in ear canal + 1/4 inch.

If the hook pulls out of the gummy bear, put a piece of ice in the ear, wait until it melts, then try again.

Or so I've heard (muffled, of course).

When I was there they were interested in gait recognition,

urine analysis

I would prefer a urine analysis test to this. I have to pee all the time and the ability to pee right at my wortstation would be welcome. My screensaver kicks in every 15 minutes though so it would keep me healthy by forcing me to drink my 8 glasses of water per day so I could stay logged in.
