Definitions
- the invention relates to a method for the biometric identification or verification of persons according to the features specified in the preamble of claim 1. Furthermore, the invention relates to a system for carrying out the method.
- biometric comparison methods can be used both for the identification and for the verification of persons.
- identification the identification of the identity takes place without prior knowledge (1: n comparison), wherein the characteristics of a person recorded biometrically with a method and / or system suitable for this purpose are compared with data records of a plurality of previously recorded persons in order to determine the identity.
- records of the person in particular stored centrally in the biometric system.
- verification the verification of a default (1: 1 comparison) takes place, wherein the biometrically recorded characteristics of a person are compared with the characteristics of a previously detected person for agreement.
- the data set to be compared can be stored centrally in the biometric system or it is also possible to save the data record on a medium, such as a Chip card, with the person to be verified, the said medium provides the system.
- a medium such as a Chip card
- the biometric features from the captured image data are calculated. It is a fundamental problem of biometric methods that an image of the biometric object, such as fingertip, face or iris, may not be distinguishable from images or copies of the object, thus deceiving the biometric system and not ensuring the security of identification or verification can be.
- biometric methods such as fingerprint, face, iris or speech
- the biometric object is "freely" accessible. Since fingerprints are left everywhere, fingerprint systems can easily be outsmarted by copies.
- iris scanner systems can be overcome relatively easily, for example by specially prepared and / or printed contact lenses or simply with photographs of the iris in the correct size ratio. It is relatively easy to make suitable copies of a biometrically measured identification object. It is a big problem of such biometric systems that it is usually not possible to decide whether the object presented for identification or verification is an original body part or just an image of it. Furthermore, any existing life detection, such as thermal, capacitive and the like, can be overcome by relatively simple technical measures.
- the quality of biometric methods and / or systems for identification using pattern recognition algorithms is usually indicated by two characteristics, False Rejection Rate (FRR) and False Acceptance Rate (FAR).
- the FRR indicates the percentage of persons or individuals mistakenly rejected by the system, although the two biometric data sets to be compared, although derived from the same individual, are not assessed consistently by the system. Ideally, this value is 0%.
- the FAR indicates the percentage of individuals falsely verified by the system, where the two biometric characteristics datasets to be compared are not from the same individual, but are considered by the system to be consistent. This value is ideally also at 0%.
- a device for scanning an object with a beam in two substantially orthogonal directions is known.
- This is a diagnostic laser scanning system by means of which a continuous laser scanning formation of the retina with different wavelengths is feasible.
- the device contains a first and a second scanner, each with a mirror whose axes of rotation extend in mutually orthogonal planes.
- the mirror of the first scanner is deflected at a predetermined distance from its axis of rotation.
- the center of the mirror of the second scanner is arranged in the middle of said distance between the axis of rotation and the mirror of the first scanner, wherein the beam from the mirror of the first scanner extends directly to the mirror of the second scanner.
- an additional optical system is present in the beam path between said mirrors.
- This laser scanning system which is also called Retinascanner allows a continuous imaging of the retina with different wavelengths, even without mydriasis or drug dilation of the pupil.
- the object of the invention is to design the method and the system in such a way that overcoming security is decisively improved in a simple and reliable manner.
- Manipulations, such as presentation of an image of the object intended for identification should be reliably detected, and furthermore the handling and / or the mode of operation should be simplified.

- This communication is tap-proof in the sense that an outside observer can not determine what information is exchanged. It is based on the finding that the human retina is difficult to access, especially as it can only be imaged with imaging systems and / or ophthalmological devices, in particular fundus cameras or laser scanning systems.
- the object to be identified or the person to be checked records visual information about the retina during the identification and / or authentication process and at the same time also forwards selectively information to the system via predefinable movements and / or fixations of the eye.
- This communication is secret, so that, for example, an outside observer can not determine what information is exchanged between the person and the system.
- light stimuli can be projected onto the retina during image acquisition, the system, in particular by means of its biometric retina laser scanner, detecting the eye movements and / or fixations, in particular in real time.
- the point to which the measured person fixes the eye is transmitted as information to the biometric system.
- the projection of stationary targets can be provided for the projection of light stimuli onto the retina.
- one of a plurality of stationary internal LED targets is randomly selected and projected onto the retina at short time intervals, preferably in the order of one second each. If the ocular fundus matches the stored biometric features and further the detected eye movements follow the faded in LEDs for a predetermined time, for example 2 to 3 seconds, the person is identified.
- any pattern can be carried out, wherein preferably a second laser is modulated by means of a synchronous output unit in addition to the laser used for image recording or a display or a monitor or targets are used for the insertion.
- the wavelength of the second laser is hidden by a filter, in particular in front of the detector, so that the superimposed pattern does not appear on the recorded image of the retina.
- a visible laser can be used and modulated for the image acquisition, wherein the insertion takes place, in particular, alternately with the image acquisition or an inverse insertion takes place.
- a check is carried out as to whether the eye follows or follows the predetermined movement and / or fixation and / or corresponding to the predetermined movement and / or fixation of the eye, an image shift, in particular by Image comparison with the or the stored original images, can be determined. If a movement of the eye from a position in which, in particular, the original image or a captured image of the eye is located in a certain direction, for example, top right, and given at a certain distance, it is checked whether the eye is the same has moved accordingly and / or fixed to the predetermined position and / or whether the detected image is displaced corresponding to the said direction and the distance.
- the insertion of a continuously moving target can be provided, wherein the eye movement has to follow the movement of the target.
- an additional display of a predetermined range such as an "alarm” and / or "silent alarm” may be provided and, depending thereon, for example a siren or a silent, in particular telephone, alarm be triggered.
