Federated ID Secure Virtual Terminal Emulation Smartcard

Abstract

A smartcard using a combination of secure virtual terminal emulation implemented by the smartcard and Federated ID information stored on the smartcard (and optionally on a transaction processor server) to provide secure verification of the personal identity of the cardholder. The Federated ID information provides a high level personal identity verification for the cardholder while secure virtual terminal emulation by the smartcard prevents the Federated ID information from being exposed to the microprocessor and memory resources of a host computer station when the smartcard is used with the host computer station to engage in transactions. The Federated ID smartcard provides a flexible, dynamically adjustable, highly efficient and secure system for personal identity verification for online commerce and a wide range of other application involving personal identity verification.

1 . A smartcard configured for secure personal identification of an associated cardholder authorized to use the smartcard, comprising:
 a portable substrate carrying a machine-readable magnetic memory strip, a microprocessor, a microprocessor interface, and a read-only memory;   wherein the microprocessor interface is configured for engaging in functional communications with a smartcard reader associated with a host computer having user input-output resources, network interface resources, microprocessor resources, and memory resources;   wherein the read-only memory residing on the smartcard stores Federated ID information for the associated cardholder;   wherein the microprocessor residing on the smartcard is configured to validate a personal identity associated with the cardholder and transmit at least a portion of the Federated ID information to a back-end transaction processor via the network interface resources of the host computer; and   wherein the microprocessor residing on the smartcard is configured to emulate a secure virtual terminal in which the smartcard controls the network interface resources of the host computer while excluding the Federated ID information from the microprocessor and memory resources of the host computer.   
   
   
       2 . The smartcard of  claim 1 , wherein the smartcard is configured to receive user-supplied personal identification information from the cardholder via the user input-output resources of the host computer while excluding the user-supplied personal identification information from the microprocessor and memory resources of the host computer. 
   
   
       3 . The smartcard of  claim 2 , wherein the smartcard is configured to validate the personal identity of the cardholder by comparing the user-supplied personal identification information to corresponding predefined personal identification information stored on the read-only memory of the smartcard. 
   
   
       4 . The smartcard of  claim 3 , wherein the user-supplied personal identification information comprises a PIN and the predefined item of identification information stored on the read-only memory residing on the smartcard comprises a predefined PIN. 
   
   
       5 . The smartcard of  claim 3 , wherein the user-supplied personal identification information comprises an electronically received handwritten signature and the predefined item of identification information stored on the read-only memory residing on the smartcard comprises a predefined handwritten signature. 
   
   
       6 . The smartcard of  claim 3 , wherein the user-supplied personal identification information comprises an electronically received biometric signature and the predefined item of identification information stored on the read-only memory residing on the smartcard comprises a predefined biometric signature.
