Fingerprint security defeated by gummy bear

OK weve recnetly had the latest CD antipiracy defeated by felt tip pens and sticky tape now to cap it all we`ve got Gummi bears defeating fingerprint sensors :

Qoute:
"Tsutomu Matsumoto used gelatine and a plastic mould to create a fake finger, which he found fooled fingerprint detectors four times out of five.

He took latent fingerprints from a glass, which he enhanced with a cyanoacrylate adhesive (super-glue fumes) and photographed with a digital camera. Using PhotoShop, he improved the contrast of the image and printed the fingerprint onto a transparency sheet.

Matsumoto took a photo-sensitive printed-circuit board (which can be found in many electronic hobby shops) and used the fingerprint transparency to etch the fingerprint into the copper.

From this he made a gelatine finger using the print on the PCB, using the same process as before. Again this fooled fingerprint detectors about 80 per cent of the time. "

If human ingenuity can create it, human ingenuity can defeat it - as long as you have enough time, money and knowledge.

I'm just surprised fingerprinting could be so "easily" foiled! <img border="0" title="" alt="[Eek!]" src="eek.gif" />

It didn't seem real easy, still...it's a vicious cycle.

Retinal scans won't be defeated so easily. You can't make an exact copy of your eye!

The one thought that does comes to mind is that if you cant access the machine then you simply hack the refference date it uses.

<a href="http://www.heise.de/ct/english/02/11/114/" target="_blank">Biometric Access Protection Devices and their Programs Put to the Test</a> gives an excellent rundown of these biometric devices and their shortfalls.

Long read, but very informative. <img border="0" title="" alt="[Wink]" src="wink.gif" />

Nice link,just shows how far a little bit of tinkering with basic ingredients can get you.
Even the USB snooping link seems to show what a security hazard it is on all new systems.
I did read of a similar device that fitted between the keyboard and its port enabling the logging of all input.
Seems no win situation for an admin against a detrmined intruder.

...unless you're dealing with a l337 scumbag. <img border="0" title="" alt="[Wink]" src="wink.gif" />
