US Patent 11444773 Biometric reference template record

Systems and methods provide for secure and efficient token generation, management, transfer, and authentication services in a biometric data environment. Various embodiments relate to a method performed by a processor of an authentication computing system. An example method includes receiving an update biometric reference sample and a user identifier, retrieving a previous biometric reference template record in a storage location based on the user identifier. The previous biometric reference template record includes a template record identifier uniquely identifying the previous biometric reference template record and a previous biometric reference template generated using a previous biometric reference sample. The method further includes comparing the update biometric reference sample to the previous biometric reference template and, if a biometric data type of the update biometric reference sample is different than that of the previous biometric reference template, generating an update biometric reference template.
