System and method for selectively initiating biometric authentication for enhanced security of financial transactions
First Claim
1. A method of selectively initiating biometric authentication for financial transactions involving an electronic portable transaction device comprising a smart card, the electronic portable transaction device including a processing module comprising a physical processor and a biometric authentication module comprising a biometric sensor and a controller, the method comprising:
- (a) collecting a first biometric sample from a user using the biometric sensor;
(b) formatting by the controller the user'"'"'s first biometric sample into a template;
(c) storing the template in a memory inside the biometric authentication module;
(d) identifying by the physical processor a transaction amount associated with an electronic transaction involving the electronic portable transaction device;
(e) retrieving by the physical processor a fixed threshold amount associated with the electronic portable transaction device;
(f) comparing by the physical processor the transaction amount and the fixed threshold amount;
(g) determining by the physical processor whether the transaction amount matches or exceeds the fixed threshold amount; and
(h) when the transaction amount matches or exceeds the fixed threshold amount, initiating by the physical processor a biometric authentication process involving the biometric authentication module, wherein the initiating a biometric authentication comprises requesting a user of the electronic portable transaction device to provide a second biometric sample, via the biometric sensor and comparing the second biometric sample to the template stored within the biometric authentication module.

Abstract
A method and system of selectively initiation biometric security based on thresholds is described. The method includes determining a transaction amount of a current transaction involving an electronic portable transaction device, retrieving a threshold amount from a data storage device, comparing the transaction amount and threshold amount, and, if the transaction amount matches or exceeds the threshold amount, initiating a biometric authentication process.
