<p>The method involves regrouping 3 minutiae for forming triangles (ABC, CDE, FGH), where each triangle has three top distribution points. Information about diameters of circumscribed circles (CCABC, CCCDE, CCFGH) is associated to the triangles. Information respectively representative of two ratios implying three angles are defined for the selected triangle, where the triangle is selected based on Delaunay triangulation method. An independent claim is also included for a device for authentication of characteristic points.</p> |
