Beschreibungdescription
Identifikationssystem zum Nachweis einer Berechtigung für ei¬ ne personennahe Benutzung einer portablen EinheitIdentification system for proving authorization for ei¬ ne personal use of a portable unit
Die Erfindung betrifft ein Identifikationssystem zum Nachweis einer Berechtigung für eine personennahe Benutzung einer por¬ tablen Einheit.The invention relates to an identification system for proving authorization for personal use of a porous unit.
Zum Nachweis einer Berechtigung für eine Benutzung einer por¬ tablen Einheit sind bereits Verfahren bekannt, die eine Si¬ cherung der portablen Einheit mittels eines einzugebenden PIN-Codes vorsehen (Personal Identification Number) . In mobi¬ len Kommunikationsendgeräten ist beispielsweise eine Eingabe dieses PIN-Codes nach einem Einschalten des Kommunikations- endgeräts oder nach einer vorgebbaren Zeitspanne einer Nicht¬ benutzung vorgesehen.For proof of authorization for use of a por¬ TableN unit processes are already known that a Si ¬ insurance entered the portable unit by means of a PIN code provide (Personal Identification Number). In mobile communication terminals, for example, an input of this PIN code is provided after switching on the communication terminal or after a predefinable period of non-use.
Die bekannten Identifikationssysteme sind nicht uneinge- schränkt geeignet, einen Bediener der portablen Einheit zu warnen, wenn diese einen personennahen Bereich verlässt, bei¬ spielsweise in Folge eines Diebstahls oder auch durch ein Vergessen der portablen Einheit.The known identification systems are not entirely suitable for warning an operator of the portable unit when it leaves a region close to the person, for example as a result of a theft or even by forgetting the portable unit.
Aufgabe der Erfindung ist es, ein verbessertes Identifikati¬ onssystem für personennah getragene portable Einheiten an¬ zugeben.The object of the invention is to provide an improved ¬ ID Case onssystem admit an¬ to people as for borne portable units.
Eine Lösung der Aufgabe erfolgt durch ein Identifikationssys- tem mit den Merkmalen des Patentanspruchs 1.A solution of the object is achieved by an identification system having the features of patent claim 1.
Die Erfindung ist geleitet von der Idee eines personennah ge¬ tragenen Codegebers, der mit der portablen Einheit inter- agiert. Eine Interaktion erfolgt in Form eines kontaktlosen Austausche von Berechtigungsinformationen zwischen einer der portablen Einheit zugeordneten Sende- und Empfangseinheit in Zusammenarbeit mit einer Auswertungseinheit sowie einem Code- geber. Der Codegeber wird dabei ebenfalls körpernah getragen und ist somit vorzugsweise in Modeaccessoires, Armbanduhren, Portemonnaies usw. untergebracht.The invention is guided by the idea of a close to people ge ¬ transmitted code generator which acts inter- with the portable unit. An interaction takes place in the form of a contactless exchange of authorization information between a transmitting and receiving unit assigned to the portable unit in cooperation with an evaluation unit and a code unit. giver. The code transmitter is also worn close to the body and is thus preferably housed in fashion accessories, watches, wallets, etc.
Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens ist darin zu sehen, dass durch eine kontaktlose bzw. drahtlose Interaktion des Codegebers mit der portablen Einheit eine Warnung des Bedieners der portablen Einheit ermöglicht wird, wenn diese einen personennahen Bereich verlässt. Diese War- nung wird im einfachsten Fall durch eine abnehmende Signalin¬ tensität der vom Codegeber übermittelten Berechtigungsinfor¬ mationen an der portablen Einheit und/oder am Codegeber ver- anlasst.A significant advantage of the method according to the invention is the fact that a warning of the operator of the portable unit is made possible by a contactless or wireless interaction of the code transmitter with the portable unit when it leaves a person-near area. This warning is caused in the simplest case by a decreasing signal intensity of the authorization information transmitted by the code transmitter to the portable unit and / or to the code transmitter.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unter¬ ansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.
Ein Ausführungsbeispiel mit weiteren Vorteilen und Ausgestal¬ tungen der Erfindung wird im folgenden anhand der Zeichnung näher erläutert.An embodiment with further advantages and Ausgestal ¬ tions of the invention will be explained in more detail below with reference to the drawing.
Dabei zeigt die einzige FIG ein Strukturbild zur schemati¬ schen Darstellung eine beispielhafte Ausführungsform des er¬ findungsgemäßen Identifikationssystems .The single FIGURE shows a structural diagram for schemati ¬ rule representation an exemplary embodiment of the he find proper identification system.
Das Identifikationssystem besteht aus der zu sicher sichern¬ den portablen Einheit PU und einem Codegeber TP, welche über eine Luftschnittstelle IF kontaktlos Berechtigungsinformatio¬ nen miteinander austauschen. Des Weiteren trägt der Benutzer einen Codegeber TP bei sich, z.B. in Form eines Stickers in Schmuckform, einer Krawattennadel, Armbanduhr, Anhängers, etc.The identification system consists of backup sichern¬ portable unit PU and a code transmitter TP, share with each other what NEN over an air interface IF contactless Berechtigungsinformatio ¬. Furthermore, the user carries a code transmitter TP with him, for example in the form of a sticker in jewelry form, a tie pin, watch, trailer, etc.
Eine Anwendung von funkbasierten Identifikationssystemen nach den RFID-Spezifikationen (Radio Frequency Identification) ist bislang als Ersatz für mechanische Schlüsselsysteme, für einen Zugangsschutz für Rechner oder bei automatischen Zah- lungssystemen usw. bekannt. Ein RFID-System besteht aus einem Codegeber TP, welcher auch elektronischer Schlüssel, RF-ID- Tag, ID-Geber oder ID-Karte genannt wird. Diesen Codegeber TP trägt der Benutzer üblicherweise bei sich oder ist - in ande- ren Anwendungsgebieten - an einem zu identifizierenden Objekt angeordnet. Der Codegeber TP ist mit Codeinformation ausges¬ tattet. Dieser Code wird über eine der portablen Einheit PU zugeordneten Sende- und Empfangseinheit SR abgefragt und in einer Auswertungseinheit EV anschließend authentifiziert oder verifiziert.An application of radio-based identification systems according to the RFID specifications (Radio Frequency Identification) has hitherto been used as a replacement for mechanical key systems, for computer access protection or for automatic payment. tion systems, etc. known. An RFID system consists of a code transmitter TP, which is also called an electronic key, RF-ID tag, ID transmitter or ID card. The user usually carries this code transmitter TP with him or is - in other fields of application - arranged on an object to be identified. The code transmitter TP is equipped with code information. This code is queried via a transceiver unit SR assigned to the portable unit PU and subsequently authenticated or verified in an evaluation unit EV.
Verschiedene funkbasierte Übertragungstechnologien sind mög¬ lich oder üblich: LF-Systeme im Frequenzbereich von 100-300 kHz, RF-Systeme bei 433 MHz oder 867 MHz und hochfrequente Mikrowellensysteme, die zumeist bei den Frequenzen 2,4 GHz, 5,8 GHz, 9,5 GHz oder 24 GHz arbeiten.Various radio-based transmission technologies are mög ¬ Lich or customary: LF systems in the frequency range of 100-300 kHz, RF systems at 433 MHz or 867 MHz and high frequency microwave systems 2.4GHz mostly at the frequencies 5.8 GHz, 9 , 5 GHz or 24 GHz.
Im vorliegenden Ausführungsbeispiel wird ein Codegeber TP mit einer passiven Identifikation verwendet. Die passive Identi- fikation zeichnet sich dadurch aus, dass der Codegeber TP ständig, ohne Zutun des Benutzers von der Sende- und Emp¬ fangseinheit SR abgefragt werden kann. Befindet sich der Co¬ degeber TP innerhalb eines gewissen Entfernungsbereiches zur Sende- und Empfangseinheit SR, so erfolgt die Identifikation automatisch. Die Beschränkung des Entfernungsbereiches ergibt sich im allgemeinen aus der Funkfelddämpfung.In the present embodiment, a code transmitter TP is used with a passive identification. Fication the passive identity is characterized in that the code transmitter TP can be constantly checked without user from the transmitting and Emp ¬ capturing unit SR. The Co ¬ degeber TP is within a certain distance range for transmitting and receiving unit SR, the identification is automatic. The limitation of the distance range generally results from the radio field attenuation.
Es ist für viele Einsatzzwecke technisch ausreichend, auf dem Codegebern TP lediglich einfache Identifikationsnummern zu speichern. Die portablen Einheit PU, also die dort angeordne¬ te Sende- und Empfangseinheit SR in Zusammenarbeit mit der Auswertungseinheit EV ist nun in der Lage, in der Nähe be¬ findliche Codegeber TP zu orten und als diejenigen des Eigen¬ tümers zu identifizieren, wobei die Reichweite der Ortung vom eingesetzten Lesegerät abhängt. Im vorliegenden Ausführungsbeispiel bilden der Codegeber TP und die portable Einheit PU eine Einheit, d.h. die portable Einheit PU reagiert nur auf ihr bekannte RFID Codegeber TP, also denen des Eigentümers.It is technically sufficient for many purposes to store only simple identification numbers on the TP. The portable unit PU, that is there is arrange ¬ th transceiver unit SR in cooperation with the evaluation unit EV is now in a position to close be ¬-sensitive code transmitter TP to locate and as to identify those of Eigen¬ tümers, the Range of the location depends on the reader used. In the present exemplary embodiment, the code transmitter TP and the portable unit PU form a unit, ie the portable unit PU only reacts to its known RFID code transmitter TP, that is to say that of the owner.
Hierbei wird folgende Funktionalität durch das Erkennen bzw. Entfernen eines bekannten RFID Codegebers aus der Reichweite der Sende- und Empfangseinheit SR erreicht:In this case, the following functionality is achieved by recognizing or removing a known RFID code transmitter from the range of the transmitting and receiving unit SR:
- Bei Erkennen eines von der portablen Einheit PU erkannten und anerkannten Codegebers TP wird die Funktion der por¬ tablen Einheit PU freigeschaltet.- Upon detection of a recognized and recognized by the portable unit PU code transmitter TP, the function of por¬ tablen unit PU is unlocked.
- Bei Verlassen des bekannten Codegebers TP aus der Reich¬ weite der portablen Einheit PU wird deren Funktion ge- sperrt. Soweit es sich bei der portablen Einheit PU um ein mobiles Kommunikationsendgerät handelt, kann vorgese¬ hen sein, dass die Wahl einer Notrufnummer bzw. anderer Notruffunktion erhalten bleibt, d.h. nicht gesperrt wird.- When leaving the known code transmitter TP from the Reich¬ range of the portable unit PU their function is blocked. As far as in the portable unit PU to a mobile communication terminal, vorgese ¬ hen may be that the choice of an emergency number or other emergency function is maintained that is not locked.
- Wahlweise kann über die portable Einheit PU ein akusti- sches Signal ausgegeben werden, das deren Eigentümer dar¬ auf hinweist, dass die Reichweite des Lesegerätes verlas¬ sen wird; sprich das Handy liegengelassen oder gestohlen wird.- Optionally, an acoustic signal via the portable unit PU issued, the dar¬ owned by indicating that the range of the reader leaving is sen ¬; say the phone is left or stolen.
Aus diesem Verfahren ergibt sich der Vorteil, das je nach Aufenthaltsorts des Eigentümers automatisch Funktionen der portablen Einheit PU gesperrt oder entsperrt werden können, welches die Missbrauchsmöglichkeiten einer gestohlenen oder verloren gegangenen portablen Einheit PU reduziert. Des Wei- teren kann durch Ausgabe eines akustischen Signals ein Ver¬ lieren bzw. Entwenden verhindert werden.From this method, there is the advantage that depending on the residence of the owner functions of the portable unit PU can be automatically locked or unlocked, which reduces the abuse possibilities of a stolen or lost portable unit PU. Furthermore, by emitting an acoustic signal, it is possible to prevent gluing or stealing.
Die Sende- und Empfangseinheit SR unterstützt in vorteilhaf¬ ter Weise eine Erkennung mehrerer persönlicher Codegeber TP z.B. eine Krawattennadel, einen Sticker, etc. Die portable Einheit PU bzw. die darin integrierte Auswerteeinheit EV sieht zu diesem Zweck einen Lernmodus vor, mit dem weitere - nicht dargestellte - Codegeber TP hinzugefügt werden können. Die Codegeber TP können hierbei bereits in speziellen Gegens¬ tänden eingebaut sein (wie z.B. in einem Sticker) oder aber als Aufkleber auf andere Gegenstände aufgebracht werden.The transmitting and receiving unit SR supported in vorteilhaf ¬ ter, a recognition of several personal code transmitter TP example, a tie clip, a sticker, etc. The portable unit PU or the built-in evaluation EV provides for this purpose a learning mode before, with the other - not shown - code transmitter TP can be added. In this case, the code transmitters TP can already be installed in special objects (such as in a sticker) or applied to other objects as stickers.
Neben der Diebstahlsicherung von mobilen Kommunikationsendge¬ räten lässt sich das beschriebene Identifikationssystem eben¬ so für die Sicherung von tragbaren MP3-Abspielgeräten, PDAs usw. einsetzen.In addition to the theft protection of mobile communication terminals, the described identification system can also be used for securing portable MP3 players, PDAs, etc.
Des Weiteren kann die Sicherung auch umgekehrt werden; so kann z.B. die portable Einheit PU in der Westentasche den Diebstahl des Portemonnaies anzeigen, sofern dieses mit einem Codegeber TP ausgestattet ist. Für eine solche Diebstahlsi- cherung ist in einer alternativen Ausführungsform der vorlie¬ genden Erfindung ein selbständiges - nicht dargestelltes - RFID-Lesegerät ohne eine Kopplung an ein die portable Ein¬ richtung PU als Signalgeber vorgesehen.Furthermore, the backup can also be reversed; Thus, for example, the portable unit PU in the vest pocket indicate the theft of the wallet, if this is equipped with a code transmitter TP. For such a theft protection of in an alternative embodiment of the invention is a self constricting vorlie¬ - not shown - RFID reader device without a coupling to a portable ¬ A PU is provided as a signal transmitter.
Gemäß einer anderen Weiterbildung der Erfindung ist eine Ver¬ wendung von nicht-personengebundenen Codegebern vorgesehen, durch die das Verhalten von signalgebenden portablen Einhei¬ ten PU gesteuert werden kann. Hierzu ist ein Konferenzraum- Codegeber vorgesehen, dessen Codeinhalt jedes in seiner Reichweite befindliche Kommunikationsendgerät anweist, eine akustische Signalisierung auf "stumm" zu schalten. According to another development of the invention, a use of non-personal code encoders is provided by which the behavior of signaling portable units PU can be controlled. For this purpose, a conference room code transmitter is provided whose code content instructs each communication terminal located within its range to switch an acoustic signaling to "silent".
