RE: Biometric question

Felix,

In short, I'm not sold on ANY biometrics security solutions.  It just seems
that, particularly since the 9/11 attacks in the U.S., that we've tried to
move too fast in implementing these sort of high-tech solutions that we
aren't entirely sure how they work, if indeed they work at all.  I'd heard
something similar about fingerprint scanners, but I just couldn't remember
how they were fooled.  Go figure... we spend hundreds of thousands of
dollars on developing a new technology like that, only to have it fooled by
something you can buy with spare change from a vending machine!  Anyway, I
remember reading not too long ago, that facial recognition scanners could be
fooled something like two-thirds of the time by holding a laptop screen up
to the scanner from a few feet away that produced a low-res image of the
person to be authenticated.  Unfortunately I can't find the article at
present - but I wouldn't think facial recognition's the way to go either.  I
think if you're planning on implementing a biometrics solution, that it
should be supplemented with the conventional password backup, or at least a
secondary biometrics solution.

One of the more memorable things that I have read about fingerprint
scanners is:
http://www.counterpane.com/crypto-gram-0205.html#5

You can basically fake a fingerprint biometric machine with a gummi
bear.  If I remember correctly, the majority of fingerprint scanners
are vulnerable to this type of attack. One of the big things to look
for is one that samples SHAPES not POINTS, and remember the more the
merrier.

As for other types of biometrics, I am not too sure, hopefully
somebody else can shed some light on those.

Hello list!

   I will work in a project where phisical security will be based on
   biometrics, in fact only will be based on fingerprints biometric.

   How secure are fingerprints?, what biometric are more secure?
(voice,
   eye, ??? what else).

   I'm not a security expert :-)

   Thanks a lot,

   Felix
