Assignee: GEORGIA TECH RESEARCH CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A system for biometric-based user identification, comprising:
a client device comprising a processor; and
an authentication application executed by the processor, wherein the application causes the client device to at least:
capture biometric data from the client device for a generation of an embedding;
generate a locality-sensitive hash (LSH) from the embedding;
determine that a set of measurements of the LSH meet a distance threshold;
generate a personal mask to identify a plurality of reliable bits based at least in part on the set of measurements of the locality sensitive hash meeting the threshold;
generate a secret that includes a cryptographic key, the cryptographic key being configured for authentication of the client device with an authentication service;
generate a masked locality-sensitive hash using a reusable fuzzy extractor based at least in part on the secret; and
send metadata to the authorization service, the metadata comprising the masked locality-sensitive hash.
