Abstract

The microcircuit identifies and authenticates fingerprints, combining in a single chip the image gathering functions and the image processing functions needed to apply fingerprint authentication techniques. To reduce the risk of the image gatherer being deceived, the microcircuit includes sensors that indicate the presence of a living human, for example a pulse detector or temperature sensor. The image gathering part of the microcircuit operates with electromagnetic radiation beyond the visible spectrum, using infra-red or ultraviolet light. The image processing can be carried out using a programmable logic circuit or a microprocessor, or a combination of the two.

Description

La présente invention concerne un micro-circuit intégrant (sur le même microcircuit et à la fois), d'une part, les fonctions de traitements des informations spécifiques à l'identification et/ou à l'authentification, par reconnaissance de l'imagez d'empreintes digitales et, d'autre part, le capteur d'image associé. The present invention relates to a micro-circuit integrating (on the same microcircuit and at the same time), on the one hand, the functions for processing information specific to identification and / or authentication, by image recognition fingerprint and, on the other hand, the associated image sensor.

On entend par micro-circuit tout type de circuit électronique miniaturisé. En particulier, une puce micro-électronique de circuit intégré en silicium est un micro-circuit. Micro-circuit means any type of miniaturized electronic circuit. In particular, a micro-electronic chip of integrated silicon circuit is a micro-circuit.

On entend par imageur tout type de capteur permettant de produire une image. En particulier, un ensemble d'éléments silicium photosensibles constitue un imageur. By imager is meant any type of sensor making it possible to produce an image. In particular, a set of photosensitive silicon elements constitutes an imager.

Les traitements spécifiques consistent, très grossièrement, à repérer les positions de certains points de la zone la plus caractéristique de l'empreinte. The specific treatments consist, very roughly, in locating the positions of certain points of the most characteristic area of the imprint.

Les applications sont nombreuses et concerne tout particulièrement l'identification. The applications are numerous and particularly concerns identification.

L'identification par empreinte digitale offre de nombreux avantages (protection contre la copie, le vol, I'oubli et la perte) par rapport aux autres moyens d'identification et/ou d'authentification (clef, badge, code et dérivés). Un marché privilégié concerne les systèmes portables (téléphones mobiles ou ordinateurs par exemple). Mais, partout où l'on doit garantir l'individualité, I'invention peut être utilisée.Fingerprint identification offers many advantages (protection against copying, theft, forgetting and loss) compared to other means of identification and / or authentication (key, badge, code and derivatives). A privileged market concerns portable systems (mobile phones or computers for example). But, wherever individuality must be guaranteed, the invention can be used.

La Figure 1 présente un schéma d'ensemble possible d'un mode de réalisation de la présente invention. On peut y distinguer différents éléments:
L'élément (1), noté imageur, correspond au dispositif permettant de produire une image de l'empreinte digitale.Figure 1 shows a possible overall diagram of an embodiment of the present invention. We can distinguish different elements:
Element (1), denoted imager, corresponds to the device making it possible to produce an image of the fingerprint.

L'élément (3) correspond au micro-circuit regroupant les deux éléments précédents ((i) et (2)). Element (3) corresponds to the micro-circuit grouping the two previous elements ((i) and (2)).

Ce micro-circuit peut disposer d'une interface (4) vers un microprocesseur ou vers un ordinateur. This micro-circuit can have an interface (4) to a microprocessor or to a computer.

Les informations échangées par le circuit (3) pouvant âtre soit brutes (comme c'est illustré par l'exemple d'image (5)), soit codées et/ou encryptées (au moyen d'algorithmes de cryptographie).  The information exchanged by the circuit (3) can be either raw (as illustrated by the example image (5)), or coded and / or encrypted (by means of cryptography algorithms).
