Biometric reference template record

A non-transitory computer readable media having computer-executable instructions embodied therein that, when executed by a computing system, causes the computing system to perform operations for updating a biometric reference template, the operations comprising:

• receiving 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 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, 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 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 an update biometric reference template, the update biometric reference template comprising the update biometric reference sample and the previous biometric reference template;
• digitally signing the update biometric reference template to generate a digitally signed message;
• tokenizing the update biometric reference sample using a first tokenization schema;
• binding a first identifier to the digitally signed message via an attribute of the digitally signed message, the first identifier identifying that the update biometric reference template comprises a tokenized biometric reference sample;
• and
• binding a second identifier to the digitally signed message via the attribute of the digitally signed message, the second identifier identifying the first tokenization schema, wherein the attribute comprises a first uniform resource identifier query string, the first uniform resource identifier query string comprising a first uniform resource locator identifying a first tokenization service provider capable of recovering the update biometric reference sample from the tokenized update biometric reference sample.

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 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, 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, the update biometric reference template comprising the update biometric reference sample and the previous biometric reference template;
• digitally sign the update biometric reference template to generate a digitally signed message;
• tokenize the update biometric reference sample using a first tokenization schema;
• bind a first identifier to the digitally signed message via an attribute of the digitally signed message, the first identifier identifying that the update biometric reference template comprises a tokenized biometric reference sample;
• and
• bind a second identifier to the digitally signed message via the attribute of the digitally signed message, the second identifier identifying the first tokenization schema, wherein the attribute comprises a first uniform resource identifier query string, the first uniform resource identifier query string comprising a first uniform resource locator identifying a first tokenization service provider capable of recovering the update biometric reference sample from the tokenized update biometric reference sample.
