Abstract
A method includes receiving an agreement associated with a signing party by a computing system, receiving a biometric sample captured from the signing party by the computing system, generating a hash of the agreement by the computing system, and receiving a secret knowledge factor by the computing system. The method further includes generating an encryption key using the secret knowledge factor as an input to a password authenticated key exchange protocol by the computing system and generating a biometric-based electronic signature token by encrypting the biometric sample and the hash of the agreement with the encryption key by the computing system. The method further includes generating a smart contract based on the agreement by the computing system. The smart contract includes terms of the agreement and the biometric-based electronic signature token. The biometric-based electronic signature token providing biometric-based pre-authorization to be initiated by the smart contract.
