Abstract: The invention relates to a method and system of securing forgery in biometrical identification of persons, wherein at least one biological characteristic of a person is recorded and transformed into personal data, and the personal data are compared with reference data in order to identify the person. The person is caused to carry out a controllable motion before, after, or during the identification and this motion is recorded. In particular, objects are displayed successively at different positions on screen, and it is verified whether the person's line of sight follows the object so as to find out whether indeed a living person rather than a copy is located in front of the identification system.

Abstract: The invention relates to a face finding method and system in a binarized image by comparing the dot group of the binarized image with the dot group of a face model, wherein the dot groups of the binarized image and of the face model are compared on the basis of the Hausdorff spacing between the dots of the dot groups and a face is recognized in the binarized image when a measure derived from the Hausdorff spacing fails to reach a limit value.
