Fun with Fingerprint Readers.

Fun with Fingerprint Readers. A Japanese cryptoanalyst recently found that he could reliably fool biometric fingerprint scanners using only gelatin like that found in gummy bears. Not only could he create a fake finger using the original, he was also successful in fooling the scanners based on a gelatin mold of a fingerprint lifted from a piece of glass.

I was talking to a security consultant last month and he mentioned that in the light of 9/11 many companies are now revisiting their threat perceptions and many security consultants now take the 'bag of thumbs' scenario into considerations (i.e. there are people who will not be above chopping off the thumbs off people to get into some places). He said that people now think that biometric identifications are still great tools to use but only if they are used ALONGWITH other more traditional authentication devices.

Yeah, Malphigian, you need those special binoculars that read retinal imprints then make you a nice set of contact lenses.

Oh wait, Alias isnt' real? Crap.

gummy bears
'bag of thumbs'

I smell a whole new candy marketing opportunity there, don't you?

i'm just glad someone hacked this dumbass idea before it became a standard and started jeopardizing everyone's security. you can bet i'll be the last one to adopt biometric identification. i don't want to be their beta tester!

That was fascinating. Done with photoshop and 10 bucks worth of household supplies. Great link. Thanks.

This mathematician did us a huge public service.

Meanwhile, that much-vaunted face recognition system doesn't seem to work so good, either.
