Etude d'un système complet de reconnaissance d'empreintes digitales pour un capteur microsystème à balayage

Abstract : Nowadays accurate personal identification is becoming more and more important. Usual means (smart cards, passwords...) have shown their limits (falsification, loss...). Biometrics (i.e. analysis of personal biological characteristics) can bring a satisfying answer to those latter problems. Currently fingerprint recognition is the most widely used technique for personal identification. Fingerprints are made up of locally parallel ridges with singular points (minutiae), and they constitute a unique permanent universal pattern. The use of ink and paper to get an image from a finger was used for a long time, but technological advances have enabled to automate the acquisition stage by means of solid state sensors. These sensors exploit different techniques to acquire the image (pressure, electrical field, temperature...) and require a static (matrix sensor) or mobile finger position (sweeping mode sensor). This work consisted in studying a full fingerprint recognition system for a sweeping mode sensor which was designed in our laboratory. The set of image processing algorithms was implemented according to sensor characteristics (pressure measurement, one line sweeping mode) and the produced fingerprint images.
