Description

Die Erfindung betrifft eine Einrichtung zum Diebstahlschutz eines Gerätes, vorzugsweise eines Autoradios, das zur Inbetriebnahme einen von einem austauschbaren Datenträger, insbesondere einer Chipkarte gelesenen Code benötigt.The invention relates to a device for theft protection a device, preferably a car radio, for Commissioning one from an exchangeable data carrier, especially a code read a chip card.

Geräte, insbesondere Autoradios und bewegliche Funkgeräte, werden häufig gestohlen. Daher haben Hersteller dieser Geräte Verfahren entwickelt, die es einem Dieb nahezu unmöglich machen, einen gestohlenen Empfänger in Betrieb zu nehmen. So ist es beispielsweise bekannt, einen Code einzugeben, wenn das Gerät von der Versorgungsspannung abgeklemmt war. Im wieder mit Spannung versorgten Gerät erfolgt dann ein Vergleich. Bei Übereinstimmung bietet das Gerät wieder die volle Funktionalität.Devices, in particular car radios and portable radio devices, are often stolen. Therefore, manufacturers have this Device developed procedures that it almost a thief make it impossible to operate a stolen receiver to take. For example, it is known to be a code to enter when the device is off the supply voltage was disconnected. In the powered device again a comparison is then made. If there is a match, it offers Device again full functionality.

Als weiteres Verfahren ist der Einsatz von Chipkarten bekannt. Bei entnommener Chipkarte ist ein Betrieb des Gerätes nicht möglich, während bei eingeführter Chipkarte das Gerät die volle Funktionalität entwickelt. Dabei werden meistens Chipkarten eingesetzt, auf denen ein gegen Schreiben geschützter Code gespeichert ist. Dieser Code wird einmalig im Rahmen der Herstellung der Chipkarte bzw. bei der Herstellung des Gerätes auf die Karte geschrieben und ein Schreibschutz aktiviert. Da die Verbreitung von Chipkarten rasch zunimmt, tragen Benutzer von Chipkarten oft viele Chipkarten bei sich.Another method is the use of chip cards known. When the chip card is removed, the Device not possible while the chip card is inserted the device develops the full functionality. In doing so mostly used chip cards on which one against Write protected code is saved. This code will once in the context of the production of the chip card or at the manufacture of the device written on the card and write protection activated. Since the spread of Smart cards are growing rapidly, and smart card users often carry them many smart cards with you.

Aufgabe der vorliegenden Erfindung ist es, die Diebstahlschutzfunktion bzw. die Inbetriebnahme eines diebstahlgeschützten Gerätes auch mit einer Chipkarte vornehmen zu können, die außerdem anderen Zwecken dient.The object of the present invention is that Theft protection function or the commissioning of a anti-theft device also with a chip card to be able to make, which also serves other purposes.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein austauschbarer Datenträger, insbesondere eine Chipkarte, einen beschreibbaren ersten Speicherplatz für einen Code und einen beschreibbaren zweiten Speicherplatz für eine Kennung aufweist, die besagt, ob am beschreibbaren ersten Speicherplatz ein gültiger Code gespeichert ist. Vorzugsweise ist dabei vorgesehen, daß in einer Lernphase von einem im Gerät befindlichen Prozessor nach Verbinden des Datenträgers mit dem Gerät die Kennung abfragbar wird, worauf bei einer nicht vorhandenen Kennung im Gerät ein Code erzeugt und in den ersten Speicherplatz des Datenträgers und in einen Speicher des Gerätes geschrieben wird und die Kennung in den zweiten Speicherplatz geschrieben wird.This object is achieved in that a exchangeable data carriers, in particular a chip card, a writable first storage location for a code and a writable second memory location for an identifier which states whether on the writable first A valid code is stored. Preferably provided that in a learning phase of one in the device located processor after connecting the disk with the device can be queried for the identifier, after which not generated a code in the device and in the first storage space of the data carrier and into a memory the device is written and the identifier in the second Storage space is written.

Außer einer Chipkarte kommen als austauschbarer Datenträger beispielsweise wiederbeschreibbare CDs oder Chips in Frage, die in anderen Gegenständen angeordnet sind, beispielsweise in einem Autoschlüssel. Die Verbindung zwischen dem Gerät und dem Datenträger kann durch direkte Kontaktgabe - wie beispielsweise bei den üblichen Chipkarten -, optisch oder elektromagnetisch erfolgen - wie bei mit Transpondern ausgerüsteten Autoschlüsseln. In addition to a chip card come as an exchangeable data carrier for example rewritable CDs or chips in question, which are arranged in other objects, for example in a car key. The connection between the device and the disk can by direct contact - like for example with the usual chip cards -, optically or done electromagnetically - as with transponders equipped car keys.

Die erfindungsgemäße Einrichtung hat den Vorteil, daß der Datenträger, insbesondere die Chipkarte - im folgenden auch Kombikarte genannt -, weder für die Verwendung zum Diebstahlschutz noch für ein individuelles Gerät ausgelegt sein muß. Derartige Maßnahmen würden nämlich beispielsweise die in großen Stückzahlen hergestellten Chipkarten erheblich verteuern.The device according to the invention has the advantage that the Data carriers, especially the chip card - also in the following Combination card called -, neither for use for Theft protection is still designed for an individual device have to be. Such measures would namely, for example the chip cards manufactured in large quantities considerably expensive.

Eine Weiterbildung der erfindungsgemäßen Einrichtung besteht darin, daß bei einer vorhandenen Kennung der Code gelesen und in den Speicher des Gerätes geschrieben wird. Damit kann mit Hilfe eines für ein erstes Gerät angelernten Datenträgers ein weiteres Gerät angelernt werden. So kann beispielsweise ein Besitzer mehrerer Autos mit jeweils einem Autoradio diese mit einer einzigen Kombikarte in Betrieb nehmen. Dabei bleibt wie auch bei einem einzigen Gerät die Möglichkeit einer Inbetriebnahme mit der Keycard erhalten. Auch wenn das Gerät derart ausgelegt ist, daß eine von mehreren Keycards zur Inbetriebnahme benutzt werden kann, bleibt dieser Vorteil bei Anwendung der erfindungsgemäßen Einrichtung erhalten.There is a further development of the device according to the invention in that the code is read with an existing identifier and is written into the memory of the device. So that can with the help of a trained for a first device Disk another device can be taught. So can for example, an owner of several cars with one each Car radio this with a single combination card in operation to take. This remains the same as for a single device Possibility of commissioning with the keycard. Even if the device is designed so that one of several key cards can be used for commissioning, this advantage remains when using the invention Receive facility.

Obwohl die erfindungsgemäße Einrichtung an sich auch bei einem Gerät anwendbar ist, das vor dem Anlernen des Datenträgers ungeschützt in Betrieb genommen werden kann, ist eine Verbindung der erfindungsgemäßen Einrichtung mit einem Diebstahlschutz ohne diesen Datenträger möglich. So kann beispielsweise für eine Inbetriebnahme die Eingabe eines Codes oder die Benutzung einer weiteren Chipkarte vorgesehen sein. Der Benutzer kann sein diebstahlgeschütztes Gerät mit der weiteren Chipkarte - im folgenden auch Keycard genannt - in Betrieb nehmen, solange er keine Kombikarte besitzt oder er es nicht als lästig empfindet, mehr Chipkarten bei sich zu tragen als nötig. Although the device according to the invention also in itself a device that can be used before teaching the Data carrier can be put into operation without protection, is a connection of the device according to the invention with theft protection possible without this data carrier. So can be used, for example, for commissioning a code or the use of another chip card be provided. The user can be theft-proof Device with the additional chip card - hereinafter also the key card called - put into operation as long as he does not have a combination card owns it or doesn't find it annoying, more Carry smart cards with you as necessary.

Die erfindungsgemäße Einrichtung ermöglicht einem Hersteller von Geräten diese mit einer Einrichtung zum Diebstahlschutz einschließlich der Keycard auszuliefern - unabhängig davon, ob der Benutzer jemals Kombikarten verwendet.The device according to the invention enables a manufacturer of devices with an anti-theft device including the keycard - regardless of whether the user ever uses combo cards.

Vorzugsweise ist bei der erfindungsgemäßen Einrichtung vorgesehen, daß der Datenträger, insbesondere die Chipkarte, einen Speicher für Daten zur Decodierung von digital codierten Verkehrsmeldungen enthält. Dieser Speicher und der Speicher für die Kennung und den Code können von zwei Bauelementen, beispielsweise einem ROM und einem EEPROM gebildet werden. Es ist jedoch auch möglich, mit einem einzigen Speicher-Bauelement zu arbeiten, wobei Schreib- und Leserechte entsprechend ausgelegt sind.Preferably in the device according to the invention provided that the data carrier, in particular the chip card, a memory for data for decoding digital contains coded traffic reports. This store and the Memory for the identifier and the code can be of two Components, for example a ROM and an EEPROM be formed. However, it is also possible to use one single memory device to work, being write and Read rights are designed accordingly.

Die Daten zur Decodierung von digital codierten Verkehrsmeldungen sind von Land zu Land unterschiedlich, so daß die Chipkarten mit diesen Daten - im folgenden auch TMC-Karten genannt - von Land zu Land individuell vertrieben werden. Der Gerätehersteller weiß jedoch oft nicht, wohin ein von ihm gefertigtes Gerät letztendlich verkauft wird. Mit der erfindungsgemäßen Einrichtung können Benutzer in jedem Land Ihr Gerät gegen Diebstahl schützen und später bei Vorhandensein einer Kombikarte diese anstelle der Keycard für die Zwecke des Diebstahlschutzes benutzen.The data for decoding digitally encoded Traffic reports vary from country to country, so that the chip cards with this data - also in the following Called TMC cards - sold individually from country to country become. However, the device manufacturer often does not know where to go a device manufactured by him is ultimately sold. With the device according to the invention, users can in Protect your device against theft in any country and later The presence of a combination card instead of the keycard use for anti-theft purposes.

Da für die erfindungsgemäße Einrichtung auf dem Datenträger keine Rechenvorgänge erforderlich sind, sondern lediglich Speicherzugriffe, ist eine möglichst preiswerte Realisierung der erf indungsgemäßen Einrichtung dadurch möglich, daß der Datenträger keinen Prozessor aufweist.As for the device according to the invention on the data carrier no calculations are required, just Memory access is an inexpensive implementation the device according to the invention possible in that the Disk does not have a processor.

Weitere Baugruppen, beispielsweise eines Autoradios, sind Stromversorgungseinrichtungen, Empfangsschaltungen und Verstärkerschaltungen und können in üblicher Weise ausgeführt sein. Für verschiedene Anzeigeund Einstell-Funktionen sind ein Display 2 und eine Tastatur 3 mit einem Mikrocomputer 4 (Prozessor) verbunden. An diesen ist auch ein Kartenleser 6 angeschlossen, in den eine Chipkarte 7 (Fig. 2) eingeführt werden kann. In an sich bekannter Weise dienen zur elektrischen Verbindung der Chipkarte mit dem Kartenleser Kontakte 7a.In the device 1 shown in FIG. 1, only the parts necessary for understanding the invention shown. Other assemblies, for example one Car radios, are power supply devices, Receive circuits and amplifier circuits and can in be carried out in the usual way. For various display and Setting functions are a display 2 and a keyboard 3 connected to a microcomputer 4 (processor). On this a card reader 6 is also connected, in one Chip card 7 (Fig. 2) can be inserted. In itself known manner serve for the electrical connection of the Chip card with the card reader contacts 7a.

Zur Speicherung von Festwerten, beispielsweise den zur Decodierung von digital codierten Verkehrsmeldungen erforderlichen Daten, dient ein Nur-Lese-Speicher 7b. Für veränderliche Daten ist in der Chipkarte 7 ein EEPROM 8 vorgesehen, dessen Speicherbereich schematisch dargestellt ist. Davon dient ein Teil, beispielsweise die Bits von 0 bis 15, als zweiter Speicherplatz und ist für eine Kennung reserviert, die besagt, ob in einem weiteren, vorgegebenen Teil (erster Speicherplatz) ein Code abgelegt ist. Die Chipkarte 7 wird im folgenden auch TMC-Karte genannt. For storing fixed values, for example for Decoding of digitally coded traffic reports required data, a read-only memory 7b is used. For changeable data is an EEPROM 8 in the chip card 7 provided, the memory area is shown schematically is. A part of it serves, for example the bits from 0 to 15, as a second storage space and is for an identifier reserved, which says whether in another, predetermined Part (first memory location) of a code. The Chip card 7 is also called TMC card in the following.

Eine vorteilhafte Belegung des ersten Speicherplatzes kann dadurch vorgenommen werden, daß der Code mehrmals abgelegt ist - beispielsweise dreimal. Damit ist die Sicherheit beim Lesen erhöht. Ferner kann der Code verschlüsselt abgelegt werden, wobei nur der Mikrocomputer 4 zur Entschlüsselung in der Lage ist.An advantageous allocation of the first storage space can be made by storing the code several times is - for example three times. So the security is with Reading increases. The code can also be stored in encrypted form be, with only the microcomputer 4 for decryption in able.

In einem Festwertspeicher 5.1 des Gerätes 1 ist ein Code bereits bei der Herstellung abgelegt, der dazu dient, das Gerät mit einer speziellen Chipkarte (Keycard) in Betrieb zu nehmen, die mit dem Gerät geliefert wird und auf der ein gültiger Code unveränderbar gespeichert ist.There is a code in a read-only memory 5.1 of the device 1 already filed during production, which serves to Device with a special chip card (keycard) in operation take that comes with the device and on the one valid code is stored unchangeable.

Bei dem Ablaufplan nach Fig. 3 wird nach einem Start 11 das Gerät bei 12 mit einer gültigen Keycard eingeschaltet. Daraufhin entnimmt der Benutzer bei 13 die Keycard und auf dem Display erscheint ein Schriftzug "Learning" bei 14. Daraufhin führt der Benutzer bei 15 die TMC-Karte 7 (Fig. 1) ein. Unterbleibt dies während einer vorgegebenen Zeit von beispielsweise 30s, schaltet das Gerät ab und kann nur wieder mit der Keycard in Betrieb genommen werden. Bei 16 prüft der Mikrocomputer 4 (Fig. 1) durch Auslesen der Kennung im reservierten Speicherbereich, ob auf der TMC-Karte 7 ein gültiger Code vorhanden ist. Ist dieses der Fall, wird dieser Code bei 17 in den Speicher 5.2 eingeschrieben.3 after a start 11 that Device turned on at 12 with a valid keycard. The user then removes the keycard and at 13 "Learning" appears at 14 on the display. The user then guides the TMC card 7 at 15 (FIG. 1). on. If this is not the case for a specified time of for example 30s, the device switches off and can only be put into operation again with the keycard. At 16 checks the microcomputer 4 (Fig. 1) by reading the ID in the reserved memory area, whether on the TMC card 7 a valid code is available. Is this the Case, this code is stored at 17 in 5.2 enrolled.

Wird jedoch bei 16 festgestellt, daß noch kein Code auf der TMC-Karte vorhanden ist, wird bei 18 ein Code seitens des Gerätes erzeugt und in den Speicher 8 (erster Speicherplatz) der TMC-Karte 7 eingeschrieben. Außerdem wird die Kennung in den zweiten Speicherplatz geschrieben. Daraufhin wird bei 19 der gleiche Code in den Speicher 5.2 eingeschrieben, womit die TMC-Karte angelernt ist und das Programm bei 20 beendet wird.However, if it is found at 16 that there is still no code on the TMC card is present, at 18 a code on the part of the Device is generated and stored in memory 8 (first memory location) the TMC card 7 registered. The identifier is also in wrote the second memory location. Thereupon at 19 the same code is written into the memory 5.2, with which the TMC card is learned and the program ends at 20 becomes.
