First Claim
Patent Images
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.

Abstract
An authentication mechanism for use with biometric systems which optimizes data extraction on areas or regions having a high probability of matching a reference biometric template, allows a reduction in both the size and number of data packet transmissions to be made to a biometric matching engine and includes data packet transmission prioritization.

10. A system for biometric data extraction and transmission of biometric feature sample data comprising:
-
a buffer capable of storing prioritized feature sample data extracted from a biometric sample, wherein prioritization of said feature sample data is based on the probability that the feature sample data will lead to an accurate identification of the person providing the biometric sample; a processor that receives higher priority feature sample data before lower priority feature sample data and is capable of 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; and an accumulation value register capable of storing an accumulation of said registration value in a register to create an accumulated registration value; wherein said processor further is capable of comparing the accumulated registration value against a threshold indicative of a successful authentication of said biometric sample with said feature template and if the accumulated registration value exceeds said threshold, said processor is capable of determining that a successful authentication has been conducted;
otherwise, said processor is capable of determining that an unsuccessful authentication has been conducted. - View Dependent Claims (11, 12, 13)
