Claim 9:
10. The method for registering a computing device of claim 1 wherein the method further register a user and their biometric identifiers with the remote authentication system, the method further comprising:
obtaining a unique user identity token from the remote authentication system;
obtaining values detected by trusted sensor mechanism(s) associated with the computing device to acquire biometric minutiae corresponding to each individual character of a secret password or passwords known to the user;
storing the biometric minutiae in a machine readable data storage mechanism associated with the computing device;
performing cryptographic operations on the biometric minutiae associated with each secret password character entered by the user in order to generate biometric digital-signatures for each of said password characters, whereby a combination of password characters and their associated biometric identifiers comprising the second and third factors in a multi-factor authentication method are created;
storing the unique user identity token and biometric minutiae with their corresponding biometric digital-signatures in a machine readable data storage mechanism associated with the computing device;
encrypting at least the user's biometric digital-signatures on the computing device using a portion of the high-entropy one-time-pad encryption key;
transmitting at least the unique user identity token and the user's encrypted biometric digital-signatures from the computing device to the remote authentication system over a network communicatively coupled to the computing device; and
storing the received user's unique identity token and the plurality of the user's biometric digital-signatures in a user registration database associated with the remote authentication system containing a plurality of records associated with (i.e., keyed with) each user's unique identity token where the association between the user and their biometric data is registered with at least one remote authentication system, whereby the user's biometric digital-signatures corresponding to their password characters facilitating their utilization as two user identity factors in future multi-factor authentication transactions with the remote authentication system is provided.
