Biometric-based identity authentication

A method of verification via an authentication system, comprising:

• obtaining an encrypted and encoded form of a biometric template vector associated with a user;
• decoding the biometric template vector;
• obtaining biometric data of the user of a same form used to create the biometric template vector;
• determining a similarity score between the decoded biometric template vector and the biometric data;
• and
• performing an action based on the similarity score.

An authentication system, comprising:

• a scanner for accessing computer-scannable media;
• a sensor for obtaining biometric data;
• one or more processor;
• and
• one or more non-transitory computer-readable media containing instructions that, when executed by the one or more processors, are configured to cause the authentication system to perform operations, the operations comprising:
• instructing the scanner to scan the computer-scannable media to obtain an encrypted and encoded form of a biometric template vector associated with a user;
• decoding the biometric template vector;
• reading biometric data of a user as sensed by the sensor, the biometric data of the user of a same form used to create the biometric template vector;
• determining a similarity score between the decoded biometric template vector and the biometric data;
• and
• performing an action based on the similarity score.
