1. A method, comprising:
generating a tokenized biometric sample by tokenizing, by a computing system, a biometric sample associated with a user, the tokenized biometric sample having a common value shared with the biometric sample, the common value comprising at least one of a length or a character set;
generating a digitally-signed tokenized biometric sample by digitally signing, by the computing system, the tokenized biometric sample with a private key associated with the user;
responsive to a biometric reference template, based on biometric data extracted from the biometric sample, matching a signing party biometric sample associated with a signing party and a record, determining, by the computing system, that the user matches the signing party; and
generating, by the computing system, a confirmation verification, the confirmation verification comprising a match value for the user and the signing party,
wherein authenticity and data integrity of the record is determined based on each of the record, the tokenized biometric sample, and a public key of a public/private key pair comprising the private key.
