Abstract: A process for reproducing hand and/or finger lines with a camera works without skin contact with the recording device. By using linearly or circularly polarized light in the paths of the illuminating and the reproducing light rays, it is possible to obtain separate representations of the patterns of the epidermis and the hypodermis. An image of the relief of the skin that is rich in contrast is obtained in this way, and it is possible to acquire information from the deeper disposed layers of the skin already supplied with blood. An algorithm searches the skin patterns of the palm of the hand for line elements of different strengths and directions (vectors). The computed numerical identification contains overall frequencies of vectors as well as amplitudes and phases of frequency components of projections of the vector image of both patterns. The process permits placing the person to be identified in a separate location from the measuring device, thereby offering complete protection of the system and enhanced security against fraud.

Abstract: The invention relates to a method for imaging hand and/or finger lines with a camera which functions without contacting the skin with the recording device. By using linear or circular polarized light in the illuminating and imaging beam path, a separate representation of the upper and lower skin pattern is made possible. In doing this, an image of the skin relief which is rich in contrast is obtained. In addition, the information regarding the deeper lying skin layers through which blood flows can be obtained. An algorithm searches the skin pattern of the hand surface for line elements of different thicknesses and direction (vectors). The calculated numeric identification contains total frequencies of occurrence of vectors, amplitudes and phases of harmonic components of projections of vector images of both patterns. The method makes it possible to identify people from a distance, to completely protect the measuring device and to provide an improved security against deception.
