Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 7:
8. A system comprising:
at least one processor; and
a non-transitory, machine-readable memory device comprising instructions stored thereon that, when executed by the at least one processor, cause the at least one processor to:
obtain a biometric representation of a subject, wherein the biometric representation was encoded from a biometric sample and, prior to encoding, the biometric sample was modified according to at least a rotation parameter;
concatenate the biometric representation with a key to generate a concatenated biometric representation;
project the concatenated biometric representation based on one or more lossy transformation parameters to generate an anonymized vector representation;
receive a second biometric representation associated with the subject;
generate a second anonymized vector representation based on the second biometric representation;
perform a 1:1 comparison between the anonymized vector representation and the second anonymized vector representation to generate a similarity score;
determine that the similarity score satisfies a similarity threshold; and
in response to determining the similarity score satisfies the similarity threshold, confirm a positive verification of an identity of the subject.
