Fingerprint identification based on dermatological features

Abstract: One of the long-standing problems of practice is the personal identification, namely ascertaining personal identification. Several methods have been adapted for solving this problem during history, from seal ring, through signature to photo. Fingerprint, as a possibility for identification is widely known from the last century. From the sixties when computers became widely used, the possibility of computerizing of identification was brought up.

In this paper we explain a fingerprint identifying system used in automatic personal identifying systems. The identification is based on dermatological characteristics, namely the unique pattern of ridges of fingers. Usually two levels of pattern are distinguished, global and local patterns

In this system we improved both the global and the local characteristics using a identification. We use the direction matrix representing orientation of ridges as global characteristics and the method of identification of bifurcations as local characteristics.
