1. A method, comprising:

  • receiving, by a server, an authentication request associated with a first party, the authentication request requesting a third party to authenticate an electronic transaction associated with the first party and associated with an identity claimed by a second party;

    querying, by the server, an electronic database for the identity claimed by the second party, the electronic database electronically associating biometric templates and identities including the identity claimed by the second party;

    identifying, by the server, a biometric template of the biometric templates in the electronic database that is electronically associated with the identity claimed by the second party;

    retrieving, by the server, a randomly selected portion of biometric data associated with the second party to the electronic transaction;

    comparing, by the server, the randomly selected portion of the biometric data associated with the second party to the biometric template electronically associated with the identity claimed by the second party;

    determining, by the server, that the randomly selected portion of the biometric data satisfies a confidence threshold associated with the biometric template that is electronically associated with the identity claimed by the second party; and

    determining, by the server, an authentication response to the authentication request, the authentication response based on the randomly selected portion of the biometric data satisfying the confidence threshold associated with the biometric template.
