Claim:
A method for detecting biometric fingerprint spoofing, the method comprising: responsive to detecting a plurality of fingers of a user on a scanner plate of a scanner, scanning the plurality of fingers to produce a first scanned image of the plurality of fingers; comparing the first scanned image of the plurality of fingers with a plurality of stored fingerprint images in a storage unit to validate an identity of the user; determining whether a match is found between the first scanned image of the plurality of fingers and one of the plurality of stored fingerprint images in the storage unit; responsive to determining that the match is found, regulating a temperature in the scanner plate to activate sweat glands in the plurality of fingers by increasing the temperature in the scanner plate using a heating element located in the scanner and regulating a temperature around the scanner plate to activate the sweat glands in the plurality of fingers by increasing the temperature around the scanner plate using an air blower associated with the scanner; rescanning the plurality of fingers after a predetermined period of time to produce a second scanned image of the plurality of fingers; determining whether a sweat pattern is found in the second scanned image of the plurality of fingers; responsive to determining that the sweat pattern is found in the second scanned image of the plurality of fingers, authorizing access to a secure object; and displaying a message to the user indicating that access is authorized.
