Abstract
Description
Die Erfindung betrifft eine Chipkarte nach dem Oberbegriff des Patentanspruches 1. The invention relates to a chip card according to the preamble of patent claim 1.
Chipkarten, die allgemein auch als Datenkarten oder häufig als Smart-Cards bezeichnet werden, sind für unterschiedlichste Anwendungsbereiche im Einsatz. Dabei sind passive Chipkarten, das heißt Chipkarten mit einem Lesespeicher (ROM, EPROM oder ähnliche Speicher), und auch aktive Chipkarten in Form einer Prozessorkarte, die beispielsweise kartenintern Daten verarbeitet, bekannt. Die Informationsübertragung erfolgt bei den bislang bekannten Chipkarten durch Berührungskontakt entsprechender Kontaktoberflächen auf der Chipkarte mit zugeordneten Lesegeräten oder durch berührungslose Datenübertragung. Häufig sind auch Kombinationen aus berührungslos und kontaktbehafteten Systemen innerhalb einer Chipkarte im Einsatz. Chip cards, which are also generally referred to as data cards or frequently as smart cards are used for a wide variety of applications. Thereby are passive Chip cards, i.e. chip cards with a read memory (ROM, EPROM or similar) Memory), and also active chip cards in the form of a processor card, for example Data processed within the card, known. The information is transferred to the previously known chip cards by corresponding contact Contact surfaces on the chip card with assigned readers or through non-contact data transmission. Combinations of non-contact are often also and contact systems within a chip card in use.
Aus der DE 196 01 391 A1 ist bereits eine Chipkarte bekannt, die einen Chipkartenkörper aufweist, in den wenigstens eine Leiterbahn integriert ist. Die Leiterbahn stellt dabei ein im wesentlichen flächenartiges Gebilde dar und bildet eine Spule oder Antenne. Bei den bekannten Chipkarten verläuft die Leiterbahn zumeist innerhalb einer Ebene. Durch einen mehrfachen Umlauf der Leiterbahn lassen sich Spulenwindungen innerhalb dieser Ebene erzeugen, sodass insgesamt ein spiralenartiges Spulenmuster entsteht. Dabei kann die Leiterbahnverlegung innerhalb des Chipkartenkörpers oder auf dem Chipkartenkörper in beliebiger Anordnung erfolgen. Die Verlegungsmöglichkeiten werden maßgeblich durch die auf der Chipkarte vorzusehenden Speicherchips beziehungsweise Anschlüsse, Schaltelemente oder Datenträger bestimmt. A chip card is known from DE 196 01 391 A1, which has a chip card body has, in which at least one conductor track is integrated. The conductor track sets in represents essential sheet-like structures and forms a coil or antenna. Both known chip cards, the conductor path usually runs within one level. Through a Multiple turns of the conductor track can be coil turns within this level generate so that overall a spiral-like coil pattern is created. The Routing inside the chip card body or on the chip card body in any order. The laying options are largely determined by the memory chips or connections to be provided on the chip card, Switching elements or data carriers determined.
Da sich Chipkarten mehr und mehr auch im bargeldlosen Zahlungsverkehr durchzusetzen beginnen, stellt der Verlust einer Chipkarte ein besonderes Risiko dar. Because chip cards are increasingly being used in cashless payments start, the loss of a chip card poses a particular risk.
Um dem zu begegnen, ist es bekannt, einen PIN-Code vorzusehen, der vom Nutzer der Chipkarte an einem entsprechenden Chipkartenlesegerät eingegeben werden muss. Dieser PIN-Code bringt zwar eine erhebliche Erhöhung der Sicherheit, hat jedoch den Nachteil, dass er häufig vergessen wird. Darüber hinaus sind bislang bekannte Chipkarten nicht absolut fälschungssicher. In order to counter this, it is known to provide a PIN code that is used by the user of the Chip card must be entered on an appropriate chip card reader. This PIN code brings a significant increase in security, but it does Disadvantage that it is often forgotten. In addition, previously known chip cards not absolutely forgery-proof.
Der Erfindung liegt die Aufgabe zu Grunde, die Fälschungssicherheit einer Chipkarte zu erhöhen. The invention is based on the object of preventing counterfeiting of a chip card increase.
Die Erfindung löst diese Aufgabenstellung mit den Merkmalen des Patentanspruches 1. The invention solves this problem with the features of claim 1.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Further embodiments of the invention are the subject of the dependent claims.
Eine erfindungsgemäße Chipkarte, die aus einem Chipkartenkörper besteht, in den eine Leiterbahn integriert ist, wird zu einer fälschungssicheren Unikat-Chipkarte, in dem die Leiterbahnen innerhalb des Chipkartenkörpers zumindest abschnittsweise eine Lagekodierung aufweisen. A chip card according to the invention, which consists of a chip card body, in one Conductor is integrated, becomes a forgery-proof unique chip card in which the Conductor tracks within the chip card body at least in sections Have position coding.
Unter einer Lagekodierung der Leiterbahn ist dabei eine universelle, karteneigene Verlegung der Leiterbahn insgesamt oder zumindest in einem lokal begrenzten Abschnitt zu verstehen. Under a position coding of the conductor track is a universal, card-specific Laying of the conductor track as a whole or at least in a locally limited section understand.
Diese erfindungsgemäße Besonderheit erschwert es oder macht es gänzlich unmöglich, eine derartige Chipkarte zu fälschen. Damit wird eine Erhöhung der Chipkartensicherheit gewährleistet. This special feature according to the invention makes it difficult or completely impossible to to forge such a chip card. This will increase chip card security guaranteed.
Diese alleinig oder als redundante Sicherheitsvorkehrung zu weiteren Systemen (bspw. PIN-Code) einsetzbare erfindungsgemäße Lösung ist einfach und kostengünstig herstellbar und erfordert bei einer erheblichen Erhöhung der Fälschungssicherheit der mit derartigen Sicherheitseinrichtungen ausgestatteten Chipkarten eine nur geringfügige Änderung der Fertigung. This alone or as a redundant safety precaution to other systems (e.g. PIN code) usable solution according to the invention is simple and inexpensive producible and requires a significant increase in counterfeit security Smart cards equipped with such security devices make only a minor change manufacturing.
Die Lagekodierung einer erfindungsgemäßen Chipkarte kann durch den Verlauf der Leiterbahn im Chipkartenkörper bestimmt sein. Dieser Verlauf weist dementsprechend eine Musterung auf, die mittels eines Lesegerätes erfassbar ist. Somit kann die Lagekodierung einer erfindungsgemäßen Chipkarte als zusätzliches Sicherheitssystem beispielsweise im bargeldlosen Zahlungsverkehr zum Einsatz kommen, wo neben der üblichen Codierung über einen PIN-Code das Lesegerät die spezielle Lagekodierung, also den Verlauf, der Leiterbahn im Chipkartenkörper erfasst und beispielsweise einen entsprechenden Vergleich mit vordefinierten Parametern durchführt. The position coding of a chip card according to the invention can be determined by the course of the Conductor in the chip card body must be determined. This course points accordingly a pattern that can be detected by means of a reading device. Thus, the Position coding of a chip card according to the invention as an additional security system for example in cashless payment transactions, where in addition to the usual coding via a PIN code the reader the special position coding, that is, the course of the conductor track in the chip card body and, for example, one corresponding comparison with predefined parameters.
Gemäß einem weiteren Vorschlag der vorliegenden Erfindung ist es möglich, die Leiterbahn der Chipkarte nicht nur innerhalb einer Ebene der Chipkarte anzuordnen. Vielmehr wird eine räumliche, also über mehrere Ebenen der Chipkarte, verlaufende Anordnung vorgesehen. Damit lässt sich die Variantenvielfalt für die Lagekodierung der erfindungsgemäßen Chipkarte in entscheidendem Maße erhöhen. Jede Änderung des Verlaufes der Leiterbahn im Chipkartenkörper wirkt individualisierend für die entsprechende Chipkarte. Dabei sind auch kleine Änderungen beziehungsweise Abweichungen von Chipkarte zu Chipkarte durch das Lesegerät in einfacher Weise, also auch aus technischer Sicht unproblematisch, zu erfassen und umzusetzen. Sie wirken sich jedoch hinsichtlich der damit erreichten Sicherheitsmöglichkeiten entscheidend aus. According to a further proposal of the present invention, it is possible to Arrange the conductor track of the chip card not only within one level of the chip card. Much more becomes a spatial arrangement, that is to say over several levels of the chip card intended. This allows the variety of variants for the position coding of the Increase the chip card according to the invention to a decisive extent. Any change in the course of the The conductor track in the chip card body has an individualizing effect for the corresponding chip card. There are also small changes or deviations from the chip card Chip card through the reader in a simple manner, including from a technical point of view unproblematic to grasp and implement. However, they affect the security options thus achieved decisively.
Eine weitere Möglichkeit der erfindungsgemäßen Lösung kann ferner darin gesehen werden, dass die Lagecodierung in einem chipkarteneigenen Informationsträger gespeichert wird. Als Informationsträger können der Mikrochip, ein Magnetstreifen, ein Barcode, optische Speicher, wie beispielweise holografische Speicher oder ähnliche Speichermedien zum Einsatz kommen. Natürlich ist auch eine Kombination dieser Speicher möglich. Another possibility of the solution according to the invention can also be seen therein be that the location coding in a chip card's own information carrier is saved. The microchip, a magnetic stripe, a barcode, optical memories, such as holographic memories or the like Storage media are used. Of course there is also a combination of these memories possible.
Von Vorteil ist es darüber hinaus, wenn die durch die Leiterbahn realisierte Lagekodierung mittels eines geeigneten Messwertsaufnehmers ermittelt wird. Dieser könnte Bestandteil eines Chipkartenlesegerätes sein. It is also advantageous if the position coding implemented by the conductor track is determined by means of a suitable measurement sensor. This could be part of it a smart card reader.
Die Messwerterfassung und Speicherung im Informationsträger kann jedoch erfindungsgemäß ebenso schon während der Herstellung der Chipkarte erfolgen. Somit lässt sich die erfasste und zu speichernde verschlüsselte oder unverschlüsselte Information beispielsweise auch als eine Zusatzinformation auf der Chipkarte selbst ablegen und später in einem entsprechenden Chipkartenlesegerät ablesen. However, data acquisition and storage in the information carrier can according to the invention also take place during the manufacture of the chip card. So you can the encrypted or unencrypted information recorded and to be stored for example as additional information on the chip card itself and read off later in an appropriate chip card reader.
Zu Unterscheiden sind hier absolute und relative Messwerte. Ein absoluter Messwert ist dabei ein Wert, der einmalig gemessen und gespeichert wird. Dies kann zum Beispiel die Lage oder Impedanz der Spule sein. Der gespeicherte Wert wird bei Verwendung der Chipkarte durch den Nutzer gemessen und mit dem gespeichertem Messwert verglichen. A distinction must be made here between absolute and relative measured values. An absolute measurement is a value that is measured and saved once. For example, the Position or impedance of the coil. The stored value is saved when using the Chip card measured by the user and compared with the stored measured value.
Hingegen bezieht sich die Erfassung eines relativen Messwertes auf die Ermittlung zweier unterschiedlicher Werte eines oder zweier Sicherheitsfeatures, die zum Beispiel einerseits in der Lage der Antenne innerhalb der Chipkarte, jedoch an unterschiedlichen Stellen und/oder beispielsweise in der Lageerfassung der Spule oder eines Hologrammes bestehen können. Diese verschiedenen Werte ändern sich nicht oder in gleichem Umfang, sodass ihre Messung und die Abspeicherung des Verhältniswertes dieser Messwerte als relativer Wert auf der Chipkarte möglich ist. Die Meßwerte werden bei Einsatz der Chipkarte durch den Nutzer erneut gemessen, wobei ein Vergleich der abgespeicherten relativen Werte mit den aus den Meßwerten ermittelten relativen Werten erfolgt. Vorteilhaft ist hierbei, dass dieses Verfahren unabhängig von Alterungsprozessen ist und zudem eine erhöhte Sicherheit gegen Fälschungen besteht. In contrast, the acquisition of a relative measured value refers to the determination of two different values of one or two security features, for example on the one hand in the position of the antenna within the chip card, but at different locations and / or for example in the position detection of the coil or a hologram can exist. These different values do not change or change in the same way Scope, so that their measurement and storage of the ratio of these Measured values as a relative value on the chip card is possible. The measured values are at Use of the chip card measured again by the user, with a comparison of the stored relative values with the relative values determined from the measured values he follows. It is advantageous here that this method is independent of aging processes and there is also increased security against counterfeiting.
Als Messwertaufnehmer zur Erfassung der Lagekodierung der Leiterbahn kann ein induktiver Messwertaufnehmer eingesetzt werden oder es ist ebenfalls möglich, mittels einer Lichtquelle im Durchlichtverfahren die gesuchten Werte zu erfassen. A can be used as a measurement sensor for recording the position coding of the conductor track inductive sensors are used or it is also possible to use a Light source using the transmitted light method to record the values sought.
Eine vorteilhafte Weiterbildung der Erfindung ist ferner darin zu sehen, dass die Chipkarte in Planquadrate aufgeteilt wird. Diese Planquadrate weisen jeweils eine Divergenz in der Lage und in der Anordnung der Leiterbahnen auf. An advantageous development of the invention is also to be seen in the fact that the chip card is divided into grid squares. These grid squares each show a divergence in the Location and in the arrangement of the conductor tracks.
Auch durch eine derartige Umsetzung der erfindungsgemäßen Lösung ist es möglich, eine universelle Lagekodierung der Chipkarte zu bilden, sodass jede Chipkarte ein Unikat ist. By implementing the solution according to the invention in this way, it is also possible to to form a universal position coding of the chip card, so that each chip card is unique is.
Ferner ist es im Sinne der Erfindung ebenso möglich, die Anordnung der Leiterbahnen im Chipkörper nach Art eines Bare-Codes vorzunehmen. Dieser ist leicht lesbar und erfordert nur eine geringfügige Veränderung der Wandstärke der Leiterbahnen in einer Ebene, was auch lokal begrenzt erfolgen kann. Furthermore, it is also possible in the sense of the invention to arrange the conductor tracks in the To carry out chip body in the manner of a bare code. This is easy to read and requires just a slight change in the wall thickness of the conductor tracks in one plane what can also take place locally.
Die Leiterbahn einer erfindungsgemäßen Chipkarte kann aus diversen elektrisch leitfähigen Werkstoffen, z. B. aus Polymeren, aus metallischen Werkstoffen, z. B. Kupfer, Aluminium, aus elektrisch leitfähigen Pasten oder aus einer Kombination verschiedener Werkstoffe bestehen. The conductor track of a chip card according to the invention can be made electrically from various conductive materials, e.g. B. from polymers, from metallic materials, for. B. copper, Aluminum, from electrically conductive pastes or from a combination of different Materials exist.
Zur Verlegung der Leiterbahn und damit zur Herstellung der Spule oder Antenne sind Siebdruckverfahren, Wicklungen, Heißprägeverfahren, Ätz- oder andere Verfahren einsetzbar. Die eine Spule oder Antenne bildende Leiterbahn ist vorzugsweise auf eine elektrisch isolierende Schichtebene aufgebracht, welche beispielsweise eine Kunststofffolie sein kann. Bekannt sind weiterhin isolierende Schichten, die als Pasten aufgebracht werden können oder aufdruckbar sind. For laying the conductor track and thus for producing the coil or antenna Screen printing processes, windings, hot stamping processes, etching or other processes used. The conductor track forming a coil or antenna is preferably on a electrically insulating layer level applied, which, for example, a Plastic film can be. Insulating layers known as pastes are also known can be applied or are printable.
Durch eine erfindungsgemäße Chipkarte wird insgesamt eine fälschungssichere Lösung zur Verfügung gestellt, die einzeln oder als redundantes System zu weiteren Sicherheitsvorkehrungen von Chipkarten oder Smart-Cards eingesetzt werden kann und die darüber hinaus kostengünstig und einfach umzusetzen ist. A chip card according to the invention provides an overall forgery-proof solution provided individually or as a redundant system to others Security measures from smart cards or smart cards can be used and the above is inexpensive and easy to implement.
Eine bevorzugte Ausführungsform einer erfindungsgemäßen Chipkarte wird nachfolgend unter Bezugnahme auf die dazugehörige Zeichnung näher erläutert. Es zeigen: A preferred embodiment of a chip card according to the invention is as follows explained in more detail with reference to the accompanying drawing. Show it:

Die in den Figuren dargestellten, insgesamt mit 5 bezeichneten Chipkarten weisen einen Informationsträger 4 auf, der vorliegend ein Chipmodul mit einem integrierten Mikrochip ist. In elektrisch leitender Verbindung mit dem Informationsträger 4 steht eine Leiterbahn 2, die in der Fig. 1 in einer Ebene der Chipkarte 5 vollständig umlaufend und als Leiterschleife ausgestaltet ist. Die Leiterbahn 2 in der Fig. 1 ist vereinfacht vierbahnig dargestellt worden. Sie ist in einer Ebene in den Chipkartenkörper 1 integriert. The chip cards shown in the figures, denoted overall by 5, have an information carrier 4 , which in the present case is a chip module with an integrated microchip. An electrically conductive connection to the information carrier 4 is a conductor track 2 , which is shown in FIG. 1 in one plane of the chip card 5 and is configured as a conductor loop. The conductor track 2 in FIG. 1 has been shown in simplified four-track fashion. It is integrated in the chip card body 1 on one level.
Die Integration der Leiterbahn 2 in den Chipkartenkörper 1 erfolgt in an sich bekannter Weise durch Einlaminieren oder Einkleben des Trägerkunststoffes in den Chipkartenkörper 1 bzw. durch Einbringen der Antenne/Spule in einen Spritzgußkartenkörper. Im oberen Bildbereich der Fig. 1 weist die Leiterbahn 2 eine Lagekodierung 3 auf. Diese besteht vorliegend aus einem Muster, welches durch den Verlauf der Leiterbahn 2 gebildet wird. Bei der Ausführungsform gemäß Fig. 1 handelt es sich um Ausformungen der Leiterbahn in Form einer digitalen Sinuskurve, die durch mehrere aufeinander folgende, geradlinige Ausbuchtungen gekennzeichnet sind. Dabei sind die Leiterbahnen im gleichen Abstand zueinander angeordnet. The conductor track 2 is integrated into the chip card body 1 in a manner known per se by laminating or gluing the carrier plastic into the chip card body 1 or by inserting the antenna / coil into an injection-molded card body. In the upper image area of FIG. 1, the conductor track 2 has a position coding 3 . In the present case, this consists of a pattern which is formed by the course of the conductor track 2 . The embodiment according to FIG. 1 is a shape of the conductor track in the form of a digital sine curve, which is characterized by several successive, straight bulges. The conductor tracks are arranged at the same distance from one another.
Die in der Fig. 2 gezeigte Schnittdarstellung einer weiteren erfindungsgemäßen Chipkarte 5 besteht aus insgesamt drei übereinander angeordneten Einzellagen 1.1, 1.2 und 1.3, die unlösbar miteinander verbunden sind, was beispielsweise durch eine entsprechende Lamination der Einzellagen erfolgen kann. Die oberste Lage 1.1 der in Fig. 2 gezeigten Chipkarte weist eine Kavität 6 auf, in welche ein Chipmodul 4 als Informationsträger eingesetzt ist. Der Informationsträger 4 weist eine elektrisch leitende Verbindung zu der Leiterbahn 2 auf. Die Leiterbahn 2 ist in der dargestellten Chipkarte 5 über mehrere Ebenen 1.1, 1.2 und 1.3 verlaufend angeordnet. Sie durchquert diese Ebenen in einer speziellen, nur für die gezeigte Chipkarte charakteristischen Anordnung. Zudem ist eine Lagekodierung 3 im Bereich der untersten Ebene 1.3 vorgesehen. Diese Lagekodierung 3 besteht bei der gezeigten Ausführungsform in einer wellenförmigen Kontur der Leiterbahn 2. Die in die einzelnen Ebenen 1.1-1.3 einlaminierten Leiterbahnen können an einem Punkt oder an mehreren Punkten mittels einer starken Lichtquelle im Durchlichtverfahren (z. B. weißes Punktlicht) sichtbar gemacht werden. Dieser Umstand ist nutzbar, um einen Wert für die Anordnung der Leiterbahn innerhalb des Chipkartenkörpers 1 zu ermitteln beziehungsweise zu generieren, der nach seiner Ermittlung dauerhaft verschlüsselt oder unverschlüsselt im Informationsträger 4 der Chipkarte gespeichert wird und somit von jedem geeigneten Chipkartenleser überprüft werden kann. Die Chipkarte ist damit universell und fälschungssicher. The sectional view shown in FIG. 2 of a further chip card 5 according to the invention consists of a total of three individual layers 1.1 , 1.2 and 1.3 arranged one above the other, which are permanently connected to one another, which can be done, for example, by appropriate lamination of the individual layers. The uppermost layer 1.1 of the chip card shown in FIG. 2 has a cavity 6 , in which a chip module 4 is inserted as an information carrier. The information carrier 4 has an electrically conductive connection to the conductor track 2 . The conductor track 2 is arranged in the illustrated chip card 5 running over several levels 1.1 , 1.2 and 1.3 . It traverses these levels in a special arrangement that is only characteristic of the chip card shown. In addition, a position coding 3 is provided in the area of the lowest level 1.3 . In the embodiment shown, this position coding 3 consists of a wavy contour of the conductor track 2 . The conductor tracks laminated into the individual levels 1.1-1.3 can be made visible at one point or at several points by means of a strong light source using the transmitted light method (e.g. white point light). This circumstance can be used to determine or generate a value for the arrangement of the conductor track within the chip card body 1 , which after its determination is stored permanently encrypted or unencrypted in the information carrier 4 of the chip card and can therefore be checked by any suitable chip card reader. The chip card is therefore universal and tamper-proof.
Anwendbar sind die erfindungsgemäßen Lösungen für sämtliche Arten von Chipkarten mit Antennen/Spulen, so beispielsweise für kontaktlose Chipkarten im ID-Bereich, für Dual- Interface-Chipkarten, für Labels jeder Art oder für Kombi- und Hybridchipkarten usw. The solutions according to the invention can be used for all types of chip cards Antennas / coils, for example for contactless chip cards in the ID area, for dual Interface chip cards, for all types of labels or for combination and hybrid chip cards etc.
