  • Method for comparison of a test fingerprint, which is in the form of an image strip sequence, with a stored reference fingerprint, and a suitable apparatus for carrying out the method
    Patent number: 7729521
    Abstract: Method of comparing a test fingerprint with a stored reference fingerprint. The stored reference fingerprint and an image strip sequence of the test fingerprint are produced, wherein image strips of the image strip sequence represent different areas of the test fingerprint. Individual distance values between each image strip of the test fingerprint and at least one section of the reference fingerprint using a distance function are determined. An overall distance value from the individual distance values are determined, the overall distance value being a measure of similarity between the test fingerprint and the reference fingerprint.

  • Method for forgery recognition in fingerprint recognition by using a texture classification of gray scale differential images
    Patent number: 7215798
    Abstract: In a method for forgery recognition in the fingerprint recognition, at first an image sequence is captured, which comprises a plurality of images of the fingerprint to be recognized. From at least two images capturing a texture captures a differential image. The texture will be compared with a predetermined texture in order to determine whether the captured image sequence comes from a real finger or from an imitation.

  • Method for detecting the relative movement of a finger in relation to a sensor surface
    Publication number: 20050271259
    Abstract: A method and system for detecting the relative movement of a finger in relation to a sensor surface. The method includes the steps of: (a) taking and temporarily storing a first partial image of the finger in a first subarea of the sensor surface, (b) tracking the movement of the finger using a movement of the first partial image of the finger by monitoring adjacent areas of the sensor surface for occurrence of partial images correlating with the temporarily stored first partial image, and (c) repeating step (b) until the tracked section of the finger has left a predetermined area of the sensor surface.
