Description

The invention relates to a device and a method for optically examining a security document, in particular a passbook. The device is particularly suitable for multiple, location-identical inspection of security documents.

In the prior art, security documents such as e.g. Passports are known which have so-called security features or characteristic features for protection against misuse, falsification and / or total counterfeiting. By means of such security features, it is possible to verify the authenticity of the security document, since the security features of counterfeiters can not be reproduced in part or in insufficient quality.

Also during production or processing, security documents must be inspected, e.g. visually checked for their security features. Thus, e.g. Production errors are identified, which can lead to erroneous results, especially in the authenticity test.

Current examination methods for security documents are inflexible and are not integrated in the line production of the security documents, that is to say for each checking operation, in particular after each processing step, a separate checking device is required in the prior art.

Therefore, it is the object of the present invention to provide a cost-effective and space-saving device as well as a corresponding method and system for the optical examination of a security document, which allow a flexible examination of documents.

This object is solved by the subject matter of independent apparatus claim 1, independent method claim 8 and independent system claim 15. Advantageous embodiments of the device are specified in the dependent claims 2 to 7 and advantageous embodiments of the method are specified in the subclaims 9 to 14. These and other embodiments will be described below.

• mindestens eine zweite optische Erfassungseinrichtung, insbesondere eine Kamera, zur Erfassung optisch wahrnehmbarer Informationen aufweist, die dazu eingerichtet ist, das Sicherheitsdokument in einer von der ersten Richtung abweichenden zweiten Richtung oder in der ersten Richtung von einer anderen Seite als die erste optische Erfassungseinrichtung optisch zu prüfen.

A first aspect of the invention relates to a device for optically examining a security document, in particular a passbook, wherein the device for optical testing

• a first optical detection device, in particular a camera, for detecting optically perceptible information, in particular one or more optically perceptible features, preferably security features, wherein the first optical detection device is adapted to visually inspect a security document in a first direction, that is optical To capture information, and
• at least one second optical detection device, in particular a camera, for detecting optically perceptible information which is adapted to visually check the security document in a second direction deviating from the first direction or in the first direction from a side other than the first optical detection device ,

In this case, a security document is to be understood as meaning a document that is designed such that the authenticity of the document can be verified. In other words, the security document has at least one security feature by means of which the authenticity of the document can be verified. Such security features are designed such that it is difficult for counterfeiters in particular to faithfully reproduce the security features.

Security documents may e.g. Passports (such as travel or diplomatic passports), identity cards, driver's licenses, credit cards or banknotes.

In particular, the security features are surface features or printed indicia. The printed features may be, in particular, one, in particular multi-colored, guilloche, a microfilm, a print luminescent under UV illumination, a printed feature with an optically variable color, a hologram, in particular a holographic portrait, a kinegram, a machine-readable zone or a watermark. A surface structure may e.g. an engraving, in particular a laser engraving, a tactile feature, a surface embossing, a window or a perforation, in particular a laser perforation be. Furthermore, the optically detectable feature may be e.g. to act, in particular luminescent, mottled or a security thread.

In particular, the security document may have the following security features (such as on the front page and / or the data page of the German passport): multi-colored guilloches (eg of the federal eagle), positive and negative microfilm elements in various sizes, luminescent imprints under UV illumination, optically variable colors , holographic portraits (eg holographic photographs of the owner), holographic 3D symbols (eg a 3D federal eagle), kinematic motion structures, color integrations in a plastic card, laser engraving, tactile features (especially applied by laser engraving), invisible under visible light Melierfasern that luminesce under UV illumination, raised or recessed surface embossing, machine-readable zones, windows, personalized security threads (especially metallized, machine-checkable security threads, which are provided with a serial number and / or name of a holder of the security document, in particular with additional optically variable Elements), watermarks and / or perforated, in particular laser perforated serial numbers (preferably wherein the serial number is laser perforated in the paper pages and in the back cover / book cover and the diameter of the holes decreases towards the back cover).

In this case, guilloches are called protective patterns of fine, intertwined lines, the line structures being resolved in reproductions of the original in dotted raster structures.

In the context of the present invention, holograms are taken to mean holographic techniques, in particular photographic images, which reproduce a true three-dimensional image of the original subject when illuminated with coherent light.

A kinegram, also referred to as a kinematic motion structure, optically variable feature or optically variable element, in the context of this specification is a two-dimensional image that varies depending on the viewing angle. Such elements may e.g. be perceptible only at a certain viewing angle or have a different color depending on the viewing angle.

As a tactile feature in the context of the invention, a tactile font is referred to.

The printed features may e.g. Fonts with such a small font size that they can only be faithfully reproduced with high-precision printing processes.

An optical test is, in particular, to be understood as the detection of visible or invisible (eg UV and / or IR radiation) light which is scattered, reflected or emitted by the security document, or transmitted or transmitted by it. For this purpose, the security document is illuminated, for example, by a suitable light source and, for example, the intensity and / or the wavelength of the scattered, reflected, emitted or transmitted light is detected or measured by means of the respective optical detection device or detection devices. In particular, at least one image of the security document is recorded by means of the optical detection device, for example when the respective detection device is designed as a camera.

In particular, an image of the security document is recorded or recorded in the optical inspection. It will be appreciated that the optical inspection after taking the image may comprise further steps, in particular data processing and / or image processing steps, which are e.g. can be performed with a computer connected to the optical detection means.

The optical detection devices are configured to visually inspect the security document in a first or second direction. In this context, the "one-way visual check" means that the security document is visually checked from a viewing position, the respective direction running along a connecting line between the viewing position and the security document or feature to be detected of the security document.

In this case, e.g. a camera lens of the optical detection device are located at the viewing position. In particular, in this case, the direction is a viewing direction of the detection device. Alternatively, however, it is also possible to position the optical detection device at a distance from the viewing position, the light scattered, reflected, emitted or transmitted by the security document being e.g. is deflected by a mirror or a light guide (optical fiber) such that it meets the optical detection means. In the latter case, the mirror or an end of the light guide facing the security document is defined as the observation position, so that the corresponding direction runs from the mirror or end of the light guide to the security document.

The second direction in which the second detection device performs the optical check deviates, in particular, from the first direction in which the first detection device checks the security document. That is, the first direction is not parallel to the second direction, but the first and second directions are at an angle to each other greater than 0 ° and smaller than 180 °.

In the case where the second detecting means also performs the optical inspection in the first direction, the optical inspection by the second detecting means is performed from a side other than the optical inspection by the first detecting means. That is, a connecting line between the viewing position of the first detecting device and the security document and a connecting line between the second viewing position and the security document are antiparallel to each other, that is, have an angle of 180 °. In other words, the viewing position of the second detection device is opposite to the viewing position of the first detection device, and the security document is between the viewing position of the first detection device Positioning device and the viewing position of the second detection device positioned.

In particular, the optical inspection device is set up to visually check the security document in a checking step by means of the first optical detection device and the second optical detection device. In this case, a simultaneous optical examination by means of the first and second optical detection device can take place in the test step, or the optical examination by means of the first and second optical detection device can take place shortly one after the other.

The device according to the invention allows an inspection of the security document at a physical position, wherein the execution of the inspection is configurable.

By means of the device, the complexity of the system and the space required for processing and / or testing stations and automation effort can be advantageously reduced. The invention therefore makes possible a variable, customer-oriented inspection concept for security documents.

The inventively provided at least two optical detection devices can advantageously be saved space for additional devices with only one detection device.

In particular, the first area does not overlap with the second area. Preferably, the first and the second area are spaced from each other. In this case, e.g. the first region of the security document may be positioned in a plane perpendicular to the first direction and / or the second region of the security document may be positioned in a plane perpendicular to the second direction.

The areas may be e.g. to trade pages or book covers of a passport or sections of a page or book cover of the passport book.

By means of the device according to the invention, it is advantageously possible to have several regions of a security document in a single module, in particular in only one Test step, visually check. As a result, further test modules can be saved, and there is a space, Prüfzeit- and cost savings.

A further embodiment provides that the apparatus further comprises a third optical detection device for detecting optically perceptible information, which is set up, in addition to the optical examination of the security document by means of the first optical detection device and the optical examination of the security document by means of the second optical detection device, the security document in particular a third region of the security document to be optically checked in a third direction deviating from the first direction and the second direction or in the first or second direction from a side other than the first or second optical detection device.

This has the advantage that in particular a further area of the security document in a module, in particular simultaneously with the other areas, can be visually checked. This results in a further space, Prüfzeit- and cost savings.

According to a further embodiment, the first direction extends at an angle, in particular perpendicular, to the second direction, that is, the first direction extends at an angle of 90 ° to the second direction.

In particular, the first direction is angled, in particular perpendicular, to the third direction. Furthermore, the second direction may extend at an angle, in particular perpendicular, to the third direction.

A vertical arrangement of the directions can e.g. be advantageous if it is the passport to be tested security document that is exfoliated so that the book cover of the passport are arranged perpendicular to each other. In this case, e.g. two different pages of the passport, in particular at the same time, are checked visually.

According to a further embodiment, the device for optical testing is set up to optically test the security document simultaneously by means of the first optical detection device and the second optical detection device. In this case, in particular, a simultaneous examination by means of the first, second and / or third optical detection device takes place. Alternatively, of course, the test by means of the first and second optical detection device can be made shortly after each other.

A simultaneous or almost simultaneous check advantageously saves time in the examination of the security document.

According to a further embodiment, the first, second and / or third detection device is set up by means of the security document emitted light to detect an optically perceptible feature, in particular a security feature of the security document.

In this case, an optically perceptible feature is any feature of the security document that can be detected by a suitable sensor or detector by means of light reflected, scattered, emitted or transmitted by the security document, in particular visible light, ultraviolet radiation or ultraviolet light and / or infrared radiation or infrared light is.

In this case, in particular, 'transmitted' means that the light passes through at least one opening or a transparent region of the security document.

In the context of the present specification, visible light or white light is electromagnetic radiation having a wavelength between 380 nm and 780 nm.

According to a further embodiment, the first optical detection device, the second optical detection device and / or the third optical detection device is / are adapted to detect the optically perceptible feature by means of an infrared radiation emitted by the security document, so that the security document by means of the emitted infrared radiation optically can be tested. In this case, the device for optical testing in particular an infrared radiation source, which is designed or adapted to irradiate the security document with infrared radiation, so that heats the security document.

The term infrared radiation or infrared light (also referred to as IR light or IR radiation) is to be understood in the context of the present specification electromagnetic radiation having a wavelength of 780 nm to 1 mm inclusive.

In this case, a radiation source for irradiating the security document with infrared radiation or infrared light can be provided, wherein different areas of the security document differ by the irradiation with the infrared radiation strongly, especially due to the different material composition of these areas. The various regions of the heated security document then emit infrared radiation of different wavelengths and / or different intensities, the infrared radiation being detected by the first, second and / or third optical detection device and used for the optical examination of the security document. In this case, the irradiation with the infrared light is used in particular to produce a thermal imbalance between the different areas of the security document.

Alternatively, the thermal imbalance can also be generated in another way, e.g. by direct heating (via heat conduction) or by transferring the security document from a warmer environment to a colder environment.

In particular, a processing step of the security document, e.g. a print or a perforation, cause different areas of the security document to be heated to different degrees. In particular, if the security document is checked immediately after such a processing step by means of the optical testing device according to the invention, the infrared radiation emitted by the different regions of the security document having different wavelengths and / or different intensities can be used for optical testing of the security document.

Further, e.g. also an RFID transponder of the security document by the action of an electromagnetic alternating field, e.g. a suitable reader to be energized so that heats the RFID transponder. The thermal radiation of the RFID transponder, which is warmer compared to the rest of the security document, can then be detected by means of the correspondingly configured optical detection device.

In the case of optical detection by means of infrared radiation, the optical detection device is, in particular, a thermal imaging camera.

In particular, the light source for illuminating the security document with infrared light is also set up to illuminate the security document with the visible light, that is, the same light source is used for generating the visible light and the infrared light. In this case, a switching device is preferably provided for switching between the generation of the visible light and the infrared light. Alternatively, of course, the optical inspection apparatus may also include a white light source for illuminating the security document with the visible light and a separate infrared light source for illuminating the security document with the infrared light.

In the context of the present specification, ultraviolet light or ultraviolet radiation (UV light or UV radiation) is to be understood as meaning electromagnetic radiation having a wavelength of 1 nm to 380 nm inclusive.

From the security document here preferably visible light is emitted. Alternatively, UV light can also be emitted from the security document. The emitted UV light may be e.g. to act on the security document scattered, reflected and / or transmitted UV light.

In this case, e.g. the security document, in particular at certain positions (for example in the form of luminescent letters or mottled fibers), contains a luminescent substance which, when irradiated with UV light, emits visible light which is detected by the first, second and / or third detection means. A luminescent substance may e.g. a fluorescent or phosphorescent substance.

In particular, the light source for illuminating the security document with the ultraviolet light is also set up to illuminate the security document with the visible light, that is, the same light source is used to generate the visible light and the UV light. Likewise, the light source for illuminating the security document with the ultraviolet light may also be set up to illuminate the security document with the infrared light. Of course, it is also possible that the light source for illuminating the security document with the UV light is set up both for illuminating the security document with the visible light and for illuminating the security document with the infrared light. In this case, a switching device is preferably provided for switching between the generation of the visible light, the UV light and / or the infrared light.
