Assignee: WELLS FARGO BANK, N.A.
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A method, comprising:
receiving, by a computing system, 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;
retrieving, by the computing system, a previous biometric reference template record in a 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;

comparing, by the computing system, 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, generating, by the computing system, an update biometric reference template comprising the update biometric reference sample and the previous biometric reference template;
generating, by the computing system, 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;

receiving, by the computing system, a biometric authentication sample and the user identifier;
comparing, by the computing system, the update biometric reference sample to the biometric authentication sample;
generating, by the computing system, a verification value related to the comparison of the update biometric reference sample to the biometric authentication sample; and
distributing the update biometric reference template record to a plurality of users.
