27. A method of acquiring finger movement velocity and direction information, the method comprising the acts of:
-
(a) acquiring a first digital image of a fingerprint;
(b) acquiring a second digital image of a fingerprint at a specific time after acquiring the first digital image; and
(c) comparing the first and second digital images for differences to calculate velocity and direction between the first and second digital images. - View Dependent Claims (28, 29)
