Abstract
The class of problems of biometrical identification using fingerprints taken by an optical scanner is studied. A new approach to developing highly efficient identification algorithms based on preliminary indexing of the reference fingerprint database using Delaunay triangulation is proposed. Analysis of numerical experiments proved the proposed method to have high generalization ability and be stable to small perturbations of the original fingerprints.
