Abstract: The method and system disclosed herein decreases the rejection rate in fingerprint capturing and authentication by a pressure actuated fingerprint sensing module. The biometric device for fingerprint recognition of a user comprises a fingerprint sensing module for capturing the fingerprint image of the user at a pre-specified pressure, or a pre-specified pressure range. The fingerprint sensing module comprises a fingerprint capturing module, a pressure sensing module, a sensor memory and a sensor controlling module. The fingerprint capturing module captures the fingerprint when the pressure applied by the finger reaches the pre-specified pressure, or when the applied pressure falls within the pre-specified pressure range. The pressure sensing module measures the pressure applied on the fingerprint capturing module. The sensor memory stores a pre-defined set of pressures or pressure ranges.

Abstract: A method and system of increasing the acceptance rate in fingerprint scans by the application of cascaded selective, plural and sequenced fingerprint recognition rules using a plurality of sensors. The finger is swiped over multiple sensors. A whole fingerprint sample is constructed from the scan of each of the multiple sensors, thereby generating a multiplicity of whole fingerprint samples. Predetermined selective, plural and sequenced fingerprint recognition rules are set for each of the whole fingerprint samples. The sequence of application of the rules is set for the fingerprint recognition. The accuracy level for fingerprint recognition is set. The selective, plural and sequenced fingerprint recognition rules are sequentially applied to match the captured fingerprint image with stored fingerprint templates. The stored fingerprint templates are sequentially filtered until the set accuracy level is achieved.
