Abstract
A system and method for authenticating a smart card user at a reader device makes use of an application on a smart card microprocessor on which information fields relating to biometric information for the user and a table of pre-defined probability of occurrence values for user authentication is stored. The smart card and a biometric sample for the user is presented to the reader device, and an application associated with the reader device automatically authenticates the user based on a match level between the stored biometric information and the presented biometric sample according to a desired probability of occurrence value from the stored table. Alternatively, the user is automatically authenticated by an application on the smart card microprocessor. The reader device reads the presented biometric sample, automatically presents what is read to the smart card application, and the smart card application then authenticates the user according to the threshold match score from the stored table that corresponds to the desired probability of occurrence value.
