Title
Verfahren und Vorrichtung zum Erfassen biometrischer Merkmale
Other Title
Living person's biometric characteristic e.g. skin lines, detecting method, involves recording part of fingerprint pattern of finger, and detecting cyclic change of size of part of fingerprint pattern
Abstract
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Erfassen biometrischer Merkmale (z. B. Linien 21-25, Bifurkationen 28, 29 von Fingerabdruecken), wobei zumindest ein Teil eines Fingerabdruck- Musters eines Fingers aufgenommen wird und wobei eine zyklische Groessenaenderung (z. B. Abstand der Linien 22, 23) zumindest eines Teils des Fingerabdruck-Musters detektiert wird.

DE 102005047754 A1 UPAB: 20070615 NOVELTY - The method involves recording a part of a fingerprint pattern of a finger, and detecting a cyclic change in size of the part of the fingerprint pattern. A determination is made to find whether the finger is a part of a living person by evaluating the cyclic change of the size of the part of the fingerprint pattern. The cyclic change of the size of the part of the fingerprint pattern is detected by evaluating the images of the part of the pattern, where the images are recorded at different time points. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for detecting biometric characteristics. USE - Used for detecting biometric characteristics of a part e.g. skin lines and bifurcations of fingerprints, in a living person. ADVANTAGE - The method detects the biometric characteristics of the living person in a reliable and cost-effective manner.
