Decentralized biometric identification and authentication network

A system comprising:

• a memory;
• and
• a processing device of a first node of a plurality of nodes, the processing device coupled to the memory, the processing device is to:
• receive a measurement unit of a plurality of measurement units, wherein the measurement unit represents a portion of a biometric measurement of a user in response to a request to authenticate the user;
• determine whether the measurement unit corresponds to a template unit of a plurality of template units, wherein the template unit represents a portion of a biometric template, wherein the biometric measurement represents a characteristic of the user that distinguishes the user from other users;
• responsive to determining that the measurement unit corresponds to the template unit, determine a sub-result of a plurality of sub-results based on a comparison between the measurement unit and the template unit, wherein the sub-result indicates a similarity between the measurement unit and the template unit;
• and
• send the sub-result to a second node of the plurality of nodes, wherein the authentication of the user is based at least in part on the sub-result.

A method comprising:

• receiving, by a processing device, a measurement unit of a plurality of measurement units, wherein the measurement unit represents a portion of a biometric measurement of a user in response to a request to authenticate the user;
• determining whether the measurement unit corresponds to a template unit of a plurality of template units, wherein the template unit represents a portion of a biometric template, wherein the biometric measurement represents a characteristic of the user that distinguishes the user from other users;
• responsive to determining that the measurement unit corresponds to the template unit, determining a sub-result of a plurality of sub-results based on a comparison between the measurement unit and the template unit, wherein the sub-result indicates a similarity between the measurement unit and the template unit;
• and
• sending the sub-result to a node of a plurality of nodes, wherein the authentication of the user is based at least in part on the sub-result.

A non-transitory computer-readable medium comprising instructions that, responsive to execution by a processing device, cause the processing device to perform operations comprising:

• receiving, by the processing device, a measurement unit of a plurality of measurement units, wherein the measurement unit represents a portion of a biometric measurement of a user in response to a request to authenticate the user;
• determining whether the measurement unit corresponds to a template unit of a plurality of template units, wherein the template unit represents a portion of a biometric template, wherein the biometric measurement represents a characteristic of the user that distinguishes the user from other users;
• responsive to determining that the measurement unit corresponds to the template unit, determining a sub-result of a plurality of sub-results based on a comparison between the measurement unit and the template unit, wherein the sub-result indicates a similarity between the measurement unit and the template unit;
• and
• sending the sub-result to a node of a plurality of nodes, wherein the authentication of the user is based at least in part on the sub-result.
