Classification: CPC H  G | IPC G  H

Claim 13:
14. A system, comprising:
a storage location comprising a plurality of biometric reference templates containing biometric reference samples;
a server system, the server system comprising a processor and instructions stored in non-transitory machine-readable media, the instructions configured to cause the server system to:
receive an update biometric reference sample and a user identifier, the user identifier uniquely identifying a user from whom the update biometric reference sample was captured,
retrieve a previous biometric reference template record in the storage location based on the user identifier, the previous biometric reference template record comprising:
a template record identifier uniquely identifying the previous biometric reference template record being associated with the user identifier, and
a previous biometric reference template generated using a previous biometric reference sample;

compare the update biometric reference sample to the previous biometric reference template,
responsive to determining that a biometric data type of the update biometric reference sample is different than that of the previous biometric reference template, generate an update biometric reference template comprising the update biometric reference sample and the previous biometric reference template,
generate an update biometric reference template record comprising:
an update biometric reference template record identifier uniquely identifying the update biometric reference template record being associated with the user identifier, and
the update biometric reference template;

receive a biometric authentication sample and the user identifier,
compare the update biometric reference sample to the biometric authentication sample,
generate a verification value related to the comparison of the update biometric reference sample to the biometric authentication sample, and
distribute the update biometric reference template record to a plurality of users.
