Abstract:
1. A method of biometric authentication comprising: a) extracting feature sample data from a biometric sample; b) prioritizing feature sample data based on the probability that the feature sample data will lead to an accurate identification of the person providing the biometric sample; c) receiving higher priority feature sample data before lower priority feature sample data and correlating a value of said prioritized feature sample data with a feature template value to determine a registration value representative of a mathematical correlation between said value of said prioritized feature sample data and said feature template value; d) accumulating said registration value in a register to create an accumulated registration value; e) comparing the accumulated registration value against a threshold indicative of a successful authentication of said biometric sample with said feature template; and f) if the accumulated registration value exceeds said threshold, determining that a successful authentication has been conducted; otherwise, determining that an unsuccessful authentication has been conducted.
