Hey, Biometrics Guys!  Get Provoked!

Hey, Biometrics Guys! Get Provoked!

Over several years we have repeatedly made clear that biometrics brings down security to the level lower than a password-only authentication where it is used together with a password in a ‘multi-entrance’ deployment, as against a...
