Definitions
- the present invention relates to a device for personal identification by means of at least one fingerprint with at least one light source for illuminating and / or for illuminating the front region of a finger and with at least one fiber-optic finger support surface for removing an optical image of the fingerprint, through which finger support surface the optical image is at least a sensor unit can be transported, in which the optical image can be converted into electrical signals.
- Devices of this generic type serve to record and process fingerprints and can be used in any areas in which personal identification is necessary.
- Exemplary in this context are the fields of computer technology, entry systems, forensics, medicine, protection systems in general, as well as banking and finance to be named.
- Such systems have at least one light source, which is arranged above the finger to be x-rayed, so that the finger is located on the finger support surface between the light source and the finger support surface. After passing through the front region of the finger and recording the information relating to the fingerprint, the light emitted by the light source passes through the fibers of the finger support surface into the sensor unit arranged below the finger support surface, in which the optical image can be converted into electrical signals.
- the present invention is based on the object of developing a generic device for person identification in a manner which, on the one hand, enables adequate and reliable results in lighting and / or fluoroscopy of the front area of the finger, but on the other hand both the device for person identification completely is visible as well as the process of person identification is understandable and transparent for the person to be identified.
- ambient light includes both the light that comes from natural light sources, such as daylight or sunlight, and the light that comes from artificial light sources that are not specifically assigned to the device according to the present invention, such as room lighting or street lighting.
- the front area of the finger according to a preferred embodiment of the device according to the present invention, from that of the finger rest area opposite side can be illuminated and / or x-rayed; the present invention is therefore based to a certain extent on the transmitted light technology, that is to say the optical image of the fingerprint is processed as a transmitted light image.
- the skin strips or papillary lines In that, during the process of personal identification, the surface of the front area of the finger bearing the skin strips or papillary lines rests on the finger support surface, the skin strips or papillary lines "close” in places the entrances of the fibers of the finger support surface, so that in these areas of the areas closed by the skin strips or papillary lines fiber-optic finger rest surface, so-called passage light that is scattered in the interior of the front region of the finger, or only very little, reaches the finger rest surface.
- the recorded optical image of the fingerprint thus passes through the fibers of the finger support surface into the sensor unit downstream of the finger support surface, in which the optical image can be converted into electrical signals.
- both the device according to the present invention is completely visible and the process of person identification is comprehensible and transparent for the person to be identified, since this person only psychologically expediently places the front area of his finger on the finger support surface must place, but does not have to put the finger in a cavity or in an opening, as is required in the devices according to the prior art (cf. PCT / WO 98/27509).
- the design for life detection (so-called "life support”) is to be mentioned, that is to say with the present invention because of the differences in brightness between the areas of the skin strips or papillary lines and the areas between the skin strips or papillary lines it is possible to observe or examine whether the illuminated object, for example the front area of the finger, is alive, that is to say, for example, blood is flowing through it and / or has a pulse.
- a person could only be identified as authenticated or authorized if their current pulse rate deviates up or down from the stored pulse rate by no more than ten percent; the pulse frequency thus becomes a further criterion for personal identification.
- additional biometric data for example relating to the pulse rate, reduce the likelihood of errors in the identification process because they make it possible to distinguish the living finger of the person to be identified from an earlier impression of this finger.
- the existing data on the changes in the transparency of the front area of the finger allow the pulse rate of the person to be identified to be determined mathematically and the transparency curve obtained in this way analogously to
- EKG electrocardiogram
- At least one artificial light source can be switched on as a secondary light source, which is preferably arranged laterally next to the finger support surface and / or whose light is expediently directed in the direction of that facing away from the sensor unit , intended for placing the front area of the finger side of the finger support surface can be emitted.
- a secondary light source which is preferably arranged laterally next to the finger support surface and / or whose light is expediently directed in the direction of that facing away from the sensor unit , intended for placing the front area of the finger side of the finger support surface can be emitted.
- the secondary light incident on the front area of the finger occurs essentially from the side, at least some of the light penetrating into the interior of the front area of the finger and being scattered there, the scattering essentially in all directions, including in particular in The direction of the fiber-optic finger support surface takes place (so-called transmitted light technology, i.e. the optical image of the fingerprint is processed as a transmitted light image; see above).
- the secondary light source is arranged on the side of the finger support surface facing the sensor unit. This is a sufficient prerequisite for the light from the secondary light source to be able to be emitted in the direction of the side of the finger support surface facing away from the sensor unit and intended for placing the front area of the finger, i.e. the front area of the finger of the one to be identified
- the person is illuminated from below from the side.
- the secondary light source can advantageously be arranged laterally spaced from the sensor unit.
- the light from the secondary light source can be laterally irradiated onto the side of the finger support surface facing away from the sensor unit and intended for placing the front area of the finger.
- This development is particularly considered when the secondary light source is preferably arranged laterally next to or already just on the side of the finger support surface facing away from the sensor unit; in this development, the secondary light source can also be arranged to lie horizontally and emit the light "flat" on the front area of the finger.

- the secondary light source is a light-emitting diode (LED), the advantage of such light-emitting diodes being in particular that they are very small and consequently can also be used in devices according to the present invention, in which little space is available in the course of miniaturization.
- the low weight, the robust design, the low operating voltage and the long service life of the light-emitting diodes are further plus points.
- the secondary light source emits infrared light, wherein the infrared light can have a wavelength of approximately 950 nanometers, for example.
- the secondary light source itself should have an output of about 25 milliwatts to avoid disproportionately high heating of the device.
