Abstract

System for biometric authentication based on magnetic resonance image of a part of the body, particularly the skull. According to the method the head needs only to be brought close to the imaging apparatus. Independent claims are made for: a recording unit with special micro-coils for detection of magnetic resonance in a very short time, together with an ADC and a computer; a computer unit with special evaluation software; evaluation software; and an authentication system.

Description

Bestreben der biometrischen Authentisierung ist es, möglichst schnell und absolut zuverlässig eine Person zu erkennen und zweifelslos zu authentifizieren. Der Stand der Technik ist jedoch von diesem Ideal weit entfernt. So gibt es Heute in der biometrischen Authentisierung einige bekannte Verfahren diese sind Fingerabdruck sowie Handleser, Gesichtsfeldscanner, Retinaleser und Irisleser. Alle haben den Nachteil, das diese manipulationsanfällig sind. So kann der Fingerabdruckleser durch ein Modell simuliert werden. Der Gesichtsfeldscanner mit einem Foto überlistet werden usw. The aim of biometric authentication is to be as quick and absolutely reliable as possible to recognize a person and to authenticate without a doubt. However, the state of the art is far from this ideal. So there are some in biometric authentication today known methods these are fingerprint as well as hand readers, visual field scanners, Retinal readers and iris readers. All have the disadvantage that they are susceptible to manipulation. So the fingerprint reader can be simulated by a model. The visual field scanner with be tricked into a photo, etc.

Erst die Authentisierung mittels der Erfassung eines 3D Bildes z. B. des Schädelinnerem schützt vor Manipulationen. Only the authentication by capturing a 3D image e.g. B. the inside of the skull protects against manipulation.

Es ist bekannt, das jedes Gehirn andere Strukturen aufweist. So kann eine zuverlässige Authentisierung durchgeführt werden. It is known that every brain has different structures. So a reliable one Authentication.

Durch ein Cluster bestehend aus speziellen Mircospulen, ist es möglich die Aufnahme in kürzester Zeit zu machen. Die Person muß den Kopf lediglich in die Nähe der Aufnahmeeinheit bringen. Ähnlich wie bei einer Kamera. Through a cluster consisting of special micro coils, it is possible to be included in to make in the shortest possible time. The person only has to keep the head close to the recording unit bring. Similar to a camera.

Wie im Kernspin-Tomographen wird dann mittels eines Rechenverfahrens anhand der Resonanz das 3D Bild des z. B. Schädels berechnet und mit dem Original verglichen. Besteht Übereinstimmung, ist die Person authentifiziert. As in a nuclear spin tomograph, a calculation method is then used to determine the Resonate the 3D image of the z. B. skull calculated and compared with the original. Consists Match, the person is authenticated.

Das System eignet sich besonders als authentifizierung von Personen sowie zur Zutrittskontrolle zu Hochsicherheitstrakts oder z. B. an Geldautomaten. The system is particularly suitable for the authentication of people and for Access control to high security wings or e.g. B. at ATMs.
