Claim 0:
1. A computer-implemented method, comprising:
receiving, by a server computer and from a first registrar computer system in a first federated network of computing devices, an authentication request to authenticate a first computing device being utilized to conduct a transaction in the first federated network of computing devices, the authentication request including a token, the token including biometric information of a user for the transaction;
identifying, by the server computer, that the token is signed by an entity residing in a second federated network of computing devices, wherein the token includes a canonical address formatting scheme for communicating with the second federated network of computing devices;
identifying, by the server computer, a network address for communicating with a second registrar computer system associated with the second federated network of computing devices based on the canonical address formatting scheme of the token;
transmitting, by the server computer, the authentication request from the first registrar computer system to the second registrar computer system using the network address;
receiving, by the server computer and from the second registrar computer system, a confirmation of the authentication request, the confirmation determined by the second registrar computer system based in part on the biometric information of the user and a signature of the token by the entity residing in the second federated network of computing devices; and
transmitting, by the server computer and to the first registrar computer system, the confirmation of the authentication request including the token, the token further signed by the first registrar computer system and provided to the first computing device for use in subsequent transactions in the first federated network of computing devices by allowing communications between the first computing device residing in the second federated network of computing devices with devices of the first federated network of computing devices without requiring additional authentication.
