Method and apparatus for biometric verification with data packet transmission prioritization
First Claim
Patent Images
1. A method of biometric authentication comprising the steps of:
- providing a first biometric information sample;
extracting biometric data from the first biometric information sample, the extracted biometric data relating to features reproducibly extractable from said biometric sample;
determining from the biometric data, feature data having a high likelihood of accurate registration with a template; and
, storing a template including one of data relating to an order of the feature data and feature data stored with an order, the order based on the determination.

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.
