Biometric electronic signature tokens

A non-transitory computer readable media having computer-executable instructions embodied therein that, when executed by a computing system, cause the computing system to perform operations for verifying a Best Electronic Signature Token (BEST), the operations comprising:

• generating a tokenized biometric sample by tokenizing 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 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 that the user matches the signing party;
• and
• generating 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.

A system, comprising:

• a storage location comprising a plurality of Biometric Electronic Signature Tokens (BESTs);
• and
• a server system comprising a processor and instructions stored in non-transitory machine-readable media, the instructions configured to cause the server system to:
• generate a tokenized biometric sample by tokenizing 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,
• generate a digitally-signed tokenized biometric sample by digitally signing 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 record, determine that the user matches the signing party, and
• generate 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.
