摘要
The invention relates to a fingerprint sensing system and a method of the fingerprint sensing system of enabling authentication of a user based on fingerprint data captured by a fingerprint sensor of the fingerprint sensing system. The method comprises capturing at least one image of a fingerprint of a user's finger contacting the fingerprint sensor, acquiring a stored image comprising impairment data caused by impairments that the fingerprint sensor is subjected to, extracting fingerprint feature data from the captured at least one image, extracting impairment feature data from the acquired image, and comparing at least a subset of the extracted fingerprint feature data to at least a subset of the extracted impairment feature data of the acquired image, and if there is a match the user is not authenticated.
