Patent ID: 7512807

Claim:
A method of biometric authentication from a biometric sample received by a local client, the method comprising: defining a plurality of regions within the biometric sample; identifying which of the plurality of regions includes biometric feature data having at least a predetermined probability of matching a pre-established reference; extracting the biometric feature data from the identified regions; incorporating the extracted biometric feature data into a plurality of data packets; arranging the plurality of data packets in a hierarchy from highest probability to lowest probability based, at least in part, on the probability of matching the pre-established reference; transmitting a data packet of the plurality of data packets having a highest known probability of the plurality of data packets of matching the pre-established reference to a biometric matching engine; and iteratively transmitting another data packet of the plurality of data packets having a highest known probability of the remaining data packets of matching the pre-established reference, if previously transmitted data packets did not result in a match at the biometric matching engine.
