Is a fake detection test necessary for all applications?
No. In practice, forgers must overcome further hurdles beyond the biometric authentication. The following examples should illustrate: • At home, one uses fingerprint authentication for access to the internet, so remembering or writing down a password is not necessary. A burglar will not have enough time to copy the appropriate finger. Naturally, he could take the entire PC including the authentication setting mode, and at his leisure make copies of the collected fingerprints (although searching for passwords would be much easier).
