SYSTEM AND METHOD FOR SELECTIVELY INITIATING BIOMETRIC AUTHENTICATION FOR ENHANCED SECURITY OF ACCESS CONTROL TRANSACTIONS

摘要

A method and system of selectively initiation biometric security based on thresholds is described. The method includes retrieving an access security level associated with an access domain and an access permission level associated with an electronic portable transaction device, comparing the access security level and access permission level, and, if the access security level exceeds the access permission level, initiating a biometric authentication process.

1. A method of selectively initiating biometric authentication in an access control system, comprising:
(a) digitally collecting a user's fingerprint as a template in a program within a portable access control device; (b) comparing an access permission level associated with the portable access control device to an access security level associated with an access domain; and (c) initiating a biometric authentication process using the fingerprint template if the access security level associated with the access domain is higher than the access permission level associated with the electronic portable transaction device.
