1. A method for authenticating, the method comprising:
acquiring first fingerprint image data from a touch-sensitive surface;
performing a first authentication process based on the first fingerprint image data, wherein the first authentication process is performed by comparing features extracted from the first fingerprint image to a database of known fingerprints;
acquiring second fingerprint image data;
determining a difference between a characteristic of the second fingerprint image data and a characteristic of the first fingerprint image data; and
performing a second authentication process based upon the difference between the characteristic of the second fingerprint image data and the characteristic of the first fingerprint image data wherein the second authentication process is performed upon the second fingerprint image, or a fingerprint image taken thereafter.
