Abstract

The invention relates to a method of authenticating a user by means of a fingerprint authentication system comprising a fingerprint sensing arrangement and authentication circuitry. The method comprises the steps of acquiring a first candidate fingerprint image; acquiring a second candidate fingerprint image; processing, while acquiring the second candidate fingerprint image, the first candidate fingerprint image by the authentication circuitry; and evaluating a result of the processing. When the evaluation indicates that successful authentication is not likely based on the first candidate fingerprint image, the user is authenticated based on the second candidate fingerprint image.
