First Claim
Patent Images
1. At a smart card reader, a method of making secure use of authentication data stored on a smart card read by said smart card reader, said method comprising:
- receiving a response Application Protocol Data Unit (APDU) from said smart card, said response APDU including authentication data from said smart card, said response APDU indicating a destination;
extracting said authentication data from said smart card from said response APDU;
storing said authentication data from said smart card;
generating a filtered response APDU, wherein said filtered response APDU does not include said authentication data from said smart card; and
transmitting said filtered response APDU toward said destination.

Abstract
A smart card reader is adapted to extract and store authentication data from a response APDU received from a smart card before generating a filtered response APDU, wherein the filtered response APDU does not include the authentication data. Beneficially, when the smart card reader transmits the filtered response APDU toward a destination, the biometric template data is less susceptible to interception, thereby providing a more secure solution.
