A BIOMETRIC SECURITY METHOD, SYSTEM AND COMPUTER PROGRAM

摘要

A biometric security method comprising the steps of: generating a plurality of test keyboard metrics from a received identity verification request; comparing a typing pattern expressed in the test keyboard metrics with those expressed in a one or more stored keyboard metrics from a plurality of registered users; refusing access to a controlled resource in the event the typing pattern expressed in the test keyboard metrics does not substantially match any of those expressed in the stored keyboard metrics; and, otherwise, determining a closest matching registered user whose typing pattern most closely matches that expressed in the test keyboard metrics; comparing the test keyboard metrics with a one or more stored keyboard metrics associated with a normally stressed state of the closest matching registered user; and allowing access to the controlled resource in the event the typing pattern expressed in the test keyboard metrics substantially matches that associated with a normally stressed state of the closest matching registered user.
