Claim 0:
1. A process comprising:
obtaining 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;
concatenating the biometric representation with a key to generate a concatenated biometric representation;
projecting the concatenated biometric representation based on one or more lossy transformation parameters to generate an anonymized vector representation;
receiving a second biometric representation associated with the subject;
generating a second anonymized vector representation based on the second biometric representation;
performing a 1:1 comparison between the anonymized vector representation and the second anonymized vector representation to generate a similarity score;
determining that the similarity score satisfies a similarity threshold; and
in response to determining the similarity score satisfies the similarity threshold, confirming a positive verification of an identity of the subject.
