Fingerprint Scanners Fooled By Play-Doh
* * Beatles-Beatles writes to tell us YubaNet is reporting that in recent tests by Stephanie C Schuckers, an associate professor of electrical and computer engineering at Clarkston University, she has shown that, among other things, biometric security measures were fooled 90% of the time by simple attacks like Play-Doh molds. From the article: "Schuckers' biometric research is funded by the National Science Foundation (NSF), the Office of Homeland Security and the Department of Defense. She is currently assessing spoofing vulnerability in fingerprint scanners and designing methods to correct for these as part of a $3.1 million interdisciplinary research project funded through the NSF."
It's one thing to fool fingerprint scanners. The ones described in the article use a photo system that takes a picture of the full print and detects similarities with prints on file. It does sound pretty easy to fool. However, what about swipe-based scanners? Or retinal scanners? Surely Play-Doh isn't durable enough to drag over a fingerprint swipe-scanner and it's probably difficult to make a good replica of an eye with the stuff.
But the real security comes with a Marine standing guard. If you can get passed that guy, the biggest problem is already solved.
Jesus saved me from my past. He can save you as well.
There are three flavors of a security pass:
1. Something you have, like badge or actual key.
2. Something you know, like a password or pass phrase.
3. Something you are, like a General, Doctor, or American citizen.
Two-form authentication (where you use two of the three above forms) is quickly becoming regconized as being much more secure. Numerous security professionals were hoping biometrics would fit into the "something you are" category, but increasingly that category is being replaced by "something you have". You can have a General's uniform or forged passport... or a playdough impression from an authenticated finger. All this study does is confirm that migration.
The road to tyranny has always been paved with claims of necessity.
I may be using the wrong term here, but why not have some sort of capicitance measuring device on the fingerprint scanner? Something a bit less sensitive than your iPod wheel or a normal laptop touchpad so it has to detect a current on the persons finger before it will even begin to scan?
Not that I've tried it, but I'm pretty sure you can use Playdoh to navigate around your iPod.
I for one have a problem logging on via the scanner after a longer bath. The damned thing won't recongize the fingerprint and won't let me logon until the skin dries and the wrinkles on the fingers go away.

It is not bad, as I give up on the computer in the evening, just don't wash your hands before a presentation
Today's submissions that were rejected include a new digital imaging chip from the folks at Univ of Rochester and the Gnope.Org release (PHP GTK Toolkit).
Out in the open and blatant only in that they're not trying to hide it. On the other hand, they're certainly not telling us, despite numerous comments asking what's going on attached to every **BB story.
Mind you, it's not like we should be surprised - they acted in exactly the same way about the Roland Piquepaille(sp?) stories, and have acted the same in the past too (anyone else remember the troll report thread and related mod bombing and moderation blacklisting? I *still* can't moderate). The bottom line is that for all slashdot seems to rail against poor customer service, they're quick to ignore their own customers.
It's official. Most of you are morons.
I got a laptop with fingerprint identification and thought it was ultra-cool to just stick my index finger on there to log in (this was to XP tablet edition).
Then I wondered if you could trick it, so I looked at my index finger, and saw that it was a loop, and then had someone else in the office try with one of their fingers that also was a loop. Nothing just by pressing down.
But, because the login software takes continuous readings (which they display!), my buddy was able to keep sliding and mashing and rotating his finger around until after 4 or 5 seconds, Bong, logged in!! We were laughing, so we tried with with three other guys here, and they all logged on. Some of them had to rotate their hand all the way around, but *everyone* got on. THIS SOFTWARE DOES NOT WORK! DO NOT TRUST IT!
I reported this to the fingerprint software people (sorry, don't remember their name), but they never responded. I just turned it off completely - it's a joke.
