Fingerprints spoofed with conductive ink

(0 comments)

I am guessing that the FBI wishes this research had come out just a bit eerlier.  Researchers at Michigan State University have figured out how to use conductive ink to create fingerprint spoofs

Biometric identifiers are the new hotness in information security, but have significant deficits as authentication tokens, including the fact that biometrics are intrinsically leaky (you reveal your retinas by looking at things and your gait by walking, and shed DNA and leave fingerprints behind everywhere you go) and they can't be revoked once they leak (you can't get new fingerprints when griefers dump your existing ones on the Internet).

We have long recognized the problems with biometrics as a form of authetication. They are the same for all shared secrets, but as noted 'very leaky'. PINs remain a more secure solution for two-factor authentication.
