Unfortunately biometrics are near to useless for remote authentication. The only context in which biometrics work is when the whole authentication chain (reader, cable, computer, network) is tamper-proof. When one of these elements can be tampered with (e.g. unplugging the fingerprint reader and sniffing to the USB traffic), it becomes &quot;something you know, that anyone can collect, that you can reproduce with an HD picture, and that you cannot revoke without losing your physical integrity&quot;.<p>I think biometrics may have a place in tamper-proof devices like iphones (infamous error 53) or biometric smartcards (need fingerprint to unlock secrets).
