Centralized biometric authentication

A communications system includes a receiver and at least one transmitter. The receiver receives, from different intermediate systems, biometric samples from parties attempting to obtain services from the intermediate systems and information characterizing the expected identifies of the parties. The at least one transmitter transmits, to the intermediate systems, verification that the biometric samples match pre-registered biometric information obtained from a storage device such that the expected identities of the parties is verified as the identities of the parties.
