Classification: CPC G | IPC G

Claim 14:
15. An anti-spoofing apparatus comprising:
a processor configured to:
extract an input embedding vector from input biometric information;
select, based on the input embedding vector, a fake embedding vector from among a plurality of fake embedding vectors of a predetermined fake model based on fake biometric information;
obtain either one or both of a real embedding vector of a real model and an enrolled embedding vector of an enrollment model the enrollment model being generated based on biometric information of an enrolled user;
determine a confidence value of the input embedding vector based on a comparison between the input embedding vector and the selected fake embedding vector and one or more other comparisons between the input embedding vector and either one or both of the real embedding vector and the enrolled embedding vector; and
determine whether the input biometric information is forged, based on the confidence value.
