Abstract
A method for performing biometric authentication is disclosed. In one example, the method includes obtaining first and second biometric templates and comparing them to determine if they match. The method also includes determining if a biometric certification token is valid. A computing device or other device may communicate with a verification system to determine the validity of the biometric certification token.
Claims21
1-20. (canceled)
A method comprising:
- receiving, as part of a transaction, by a computing device, a first biometric template of a user and a biometric certification token that is a hash of a second biometric template and is signed by a verification system comprising a blockchain system;
- sending, by the computing device to a portable device, the first biometric template, wherein the portable device verifies that the first biometric template matches the second biometric template, the second biometric template being stored on the portable device;
- sending, by the computing device to the verification system, the biometric certification token, wherein the verification system verifies that the biometric certification token is stored within the blockchain system;
- and
- allowing, by the computing device, the transaction to proceed based on receiving an indication from the portable device that the first biometric template matches the second biometric template, and receiving an indication from the verification system that the biometric certification token is stored within the blockchain system.

A computing device comprising:
- a processor;
- and
- a computer readable medium, the computer readable medium comprising code, executable by the processor, to implement a method comprising:
- receiving, as part of a transaction a first biometric template of a user and a biometric certification token that is a hash of a second biometric template and is signed by a verification system comprising a blockchain system;
- sending, to a portable device, the first biometric template, wherein the portable device verifies that the first biometric template matches the second biometric template, the second biometric template being stored on the portable device;
- sending, to the verification system, the biometric certification token, wherein the verification system verifies that the biometric certification token is stored within the blockchain system;
- and
- allowing the transaction to proceed based on receiving an indication from the portable device that the first biometric template matches the second biometric template, and receiving an indication from the verification system that the biometric certification token is stored within the blockchain system.
5 more elements
A method comprising:
- sending, by a portable device to a computing device, a biometric certification token that is a hash of a first biometric template stored by the portable device and signed by a verification system comprising a blockchain system;
- receiving, by the portable device from the computing device, a second biometric template of a user;
- verifying, by the portable device that the first biometric template matches the second biometric template;
- and
- sending, by the portable device to the computing device, an indication that the first biometric template matches the second biometric template, wherein the computing device allows a transaction to proceed after the computing device receives the indication and verifies that the biometric certification token is stored on the blockchain system.
