Abstract
Description
Die Erfindung bezieht sich auf eine Anwendung und ein Verfahren zur Prüfung von Dokumenten.The invention relates to an application and a method for checking documents.
Bisher werden Dokumente mit beugungsoptischen Sicherheitsschichten, insbesondere Hologrammen, mit aufwendiger optischer Prüftechnik kontrolliert. Dabei muß das Prüfobjekt sehr genau positioniert werden. Der gesamte Prüfprozeß dauert dabei so lange, daß diese Prüfverfahren in schnellaufenden Bearbeitungsmaschinen keine Anwendung finden. Ein Test beispielsweise von Banknoten mit Hologrammechtheitsmerkmal ist innerhalb einer Banknotenzählmaschine nicht möglich, da diese mit Geschwindigkeiten zwischen 500 und 1500 Banknoten pro Minute und darüber hinaus arbeitet. Die DE 27 47 156 beschreibt ein Verfahren und ein Prüfgerät zur Echtheitsprüfung holographisch abgesicherter Identitätskarten. Das Hologramm wird reproduziert und eine Sichtkontrolle durchgeführt. Für eine schnelle, effiziente, personenunabhängige Prüfung ist dieses Verfahren nicht geeignet. In der EP 0 042 946 wird eine Vorrichtung zur Erzeugung von Abtastmustern beschrieben, die mittels Laser, Spiegel- und Linsensystem sowie einem Photodetektor geprüft werden. Der ökonomische Aufwand ist auch in diesem Fall sehr hoch. Er würde noch weiter steigen, wenn das Prüfgut unsortiert kontrolliert werden soll. Um eine Vorsortierung zu vermeiden, wäre eine mehrfache Anordnung des Echtheitsprüfsystems notwendig.So far, documents with diffractive security layers, in particular Holograms checked with complex optical testing technology. The test object must be very be positioned exactly. The entire test process takes so long that this Test methods are not used in high-speed processing machines. A test for example, banknotes with hologram authenticity is within one Banknote counting machine is not possible, as it runs at speeds between 500 and 1500 Banknotes per minute and beyond works. DE 27 47 156 describes a method and a test device for checking the authenticity of holographically secured identity cards. The The hologram is reproduced and a visual inspection is carried out. For fast, efficient, This procedure is not suitable for people-independent testing. EP 0 042 946 describes a Device for generating scanning patterns described by means of laser, mirror and Lens system and a photodetector can be checked. The economic effort is also in very high in this case. It would increase even further if the test material checked unsorted shall be. In order to avoid pre-sorting, a multiple arrangement of the Authenticity checking system necessary.
Aufgabe der Erfindung ist es, die Nachteile des Standes der Technik zu beseitigen und eine Anwendung und ein Verfahren zur Prüfung von Dokumenten mit beugungsoptisch wirksamen Sicherheitsschichten, insbesondere Hologrammen, vorzuschlagen, die schnell, personenunabhängig und mit geringem Aufwand zu realisieren sind. Das Verfahren soll sowohl in Dokumentenprüfeinrichtungen und Geldbearbeitungsmaschinen, als auch in Handprüfgeräten zur Prüfung von Dokumenten mit beugungsoptisch wirksamen Sicherheitsschichten Anwendung finden.The object of the invention is to eliminate the disadvantages of the prior art and a Application and method for checking documents with optically diffractive effects To propose security layers, particularly holograms, which are fast, can be implemented independently of people and with little effort. The procedure is said to be both in Document checking devices and money processing machines, as well as in manual checking devices Examination of documents with diffractive optical security layers application Find.
Diese Aufgabenstellung wird durch die im kennzeichnenden Teil des Anspruchs 1 gegebenen Merkmale gelöst.This task is given by the characterizing part of claim 1 Features resolved.
Der Einsatz von Hologrammen und anderen beugungsoptisch wirksamen Sicherheitsschichten zur Sicherung von Urkunden und anderen Wertpapieren sowie Banknoten gegen Fälschungen ist gegenwärtig immer häufiger anzutreffen. Eine schnelle Prüfbarkeit stellt eine weitere Sicherheitsstufe beim Bewerten der beugungsoptisch wirksamen Schichten als Echtheitsmerkmal dar. Beugungsoptisch wirksame Schichten bestehen unter anderem aus einer metallisierten Schicht. Diese Metallisierungsschicht ist elektrisch leitend. Entsprechend der Schichtdicke ändert sich die elektrische Leitfähigkeit. Die beugungsoptisch wirksame Schicht weist eine diskontinuierliche Metallisierungsschicht und/oder partiell metallische Schichten und/oder Zonen metallischer Schichten in unterschiedlichen Ebenen auf. Es sind verschiedene Meßverfahren bekannt, welche eine elektrische Leitfähigkeit nachweisen. In der Praxis hat sich das kontaktlose, kapazitive Meßverfahren als praktikabel erwiesen. Bei diesem Verfahren zur Prüfung von Sicherheitsdokumenten wird die kapazitive Kopplung zwischen Sender und Empfänger und Übertragung von Energie zwischen Sender und Empfänger durch Überbrückung eines elektromagnetischen Feldes durch elektrisch leitende Sicherheitsmaterialien ausgenutzt. Eine nachfolgende Auswerteelektronik vergleicht das Signalbild des Prüflings mit entsprechenden Referenzsignalen. Der Vergleich liefert ein klassifizierendes Signal zur Weiterverarbeitung. Dementsprechend könnte beispielsweise ein als Falsifikat erkanntes Dokument aussortiert werden, indem die Prüfeinrichtung gestoppt wird. Das Signalbild ist abhängig von der Struktur der metallisierten Schicht der beugungsoptisch wirksamen Schicht. Weisen die beugungsoptisch wirksamen Schichten eine diskontinuierliche Metallisierungsschicht auf so besitzen mehrere Segmente der Metallisierungsschicht unterschiedliche elektrische Leitfähigkeiten. Die Praxis hat gezeigt, daß diese unterschiedlichen Leitfähigkeiten sich auf das Signalbild auswirken. The use of holograms and other diffractive optical security layers for Securing documents and other securities as well as banknotes against counterfeiting is becoming increasingly common at the moment. A quick testability is another Security level when evaluating the diffraction-optically effective layers as an authenticity feature Diffraction-optically effective layers consist, inter alia, of a metallized one Layer. This metallization layer is electrically conductive. Changes according to the layer thickness the electrical conductivity. The diffraction-optically effective layer has one discontinuous metallization layer and / or partially metallic layers and / or zones metallic layers in different levels. There are different measuring methods known, which demonstrate electrical conductivity. In practice, the contactless, capacitive measuring methods proved to be practicable. In this procedure for testing The capacitive coupling between sender and receiver and security documents Transmission of energy between transmitter and receiver by bridging one electromagnetic field exploited by electrically conductive safety materials. A The following evaluation electronics compare the signal image of the test object with the corresponding one Reference signals. The comparison provides a classifying signal for further processing. Accordingly, for example, a document recognized as a false certificate could be sorted out, by stopping the test equipment. The signal pattern depends on the structure of the metallized layer of the diffraction-optical layer. Assign the diffraction optically effective layers have a discontinuous metallization layer on so several Segments of the metallization layer have different electrical conductivities. The practice has shown that these different conductivities affect the signal pattern.
Eine weitere Erhöhung der Prüfsicherheit ergibt sich aus der Kombination der Prüfung der elektrischen Leitfähigkeit mit weiteren Echtheitsmerkmalen der beugungsoptisch wirksamen Schicht. Durch Einbringen von zusätzlichen Echtheitsmerkmalen in demetallisierte Segmente innerhalb von diskontinuierlichen Metallisierungsschichten und/oder partiell metallischen Schichten und/oder zwischen Zonen metallischer Schichten in unterschiedlichen Ebenen lassen sich gleichzeitig diese Merkmale sowie die elektrische Leitfähigkeit prüfen. Mittels der Auswerteelektronik wird ein Echtheitssignal eines weiteren Sensors zur Echtheitsbestimmung logisch mit dem Sensor zur Messung der elektrischen Leitfähigkeit verknüpft. Am Ausgang der Auswerteelektronik liegt ein die beugungsoptisch wirksame Schicht klassifizierendes Signal zur weiteren Verarbeitung an. Dieses zusätzliche Echtheitsmerkmal besitzt fluoreszierende, phosphoreszierende oder Licht absorbierende Eigenschaften oder unterscheidet sich durch unterschiedliche magnetische Eigenschaften von dessen Umgebung. Dementsprechend findet ein optischer oder magnetischer Sensor Anwendung. Zur Verminderung von Detektions- und Meßfehlern wird vorzugsweise ein Sensorträger verwendet. Dieser Sensorträger nimmt alle Sensoren zur Detektion von Echtheitsmerkmalen auf. Die Abstände zwischen den Sensoren werden so minimiert und die Sensoren immer in definierter Lage angeordnet. Um Störeinflüsse zu vermeiden, wird der Sensorträger kompakt mit einer Platine verbunden, welche die Auswerteelektronik trägt. Die gesamte Prüfeinrichtung befindet sich innerhalb von Bearbeitungsmaschinen, so daß keine zusätzlichen Aufwendungen zum Transport der Prüfobjekte notwendig sind.A further increase in test reliability results from the combination of testing electrical conductivity with further authenticity features of the diffraction optically effective Layer. By introducing additional authenticity features into demetalized segments within discontinuous metallization layers and / or partially metallic Leave layers and / or between zones of metallic layers in different levels check these features and the electrical conductivity at the same time. By means of the Evaluation electronics become an authenticity signal of another sensor for authenticity determination logically linked to the sensor for measuring the electrical conductivity. At the exit of the The evaluation electronics are provided with a signal that classifies the diffraction-optically effective layer further processing. This additional authenticity feature has fluorescent, phosphorescent or light absorbing properties or differs by different magnetic properties of its environment. Accordingly, a optical or magnetic sensor application. To reduce detection and A sensor carrier is preferably used for measurement errors. This sensor carrier takes them all Sensors for the detection of authenticity features. The distances between the sensors are minimized and the sensors are always arranged in a defined position. To avoid interference avoid, the sensor carrier is compactly connected to a circuit board that the Evaluation electronics carries. The entire test facility is located within Processing machines, so that no additional expenses for the transport of the test objects are necessary.
