Definitions
- the invention relates to a code input device for a predetermined set of code characters, for example for an access or authorization control device, with an actuating device, an electronic processing unit and a display device.
- control devices In order to prevent unauthorized persons from gaining access to secure rooms or from using devices and devices that are only reserved for authorized users, control devices are known to be used in which the user must enter a coded proof of authorization. An electronic processing unit checks the code and only releases it if the specified code characters are entered in the correct order. Keyboards for typing code characters are very common. Although they have proven themselves very well, it cannot be ruled out that the entered code characters will be misused using fingerprints and that the authorization identification will be reconstructed in this way by an unauthorized person.
- Electronic input devices for a code have long been known, which have a keypad for entering the code.
- Such input devices with a keypad are easy to use for a user, since he sees the individual code characters of the code on the keyboard and only has to type the corresponding keys in the correct order.
- the authorization code can be determined relatively easily in the case of fraudulent intent with these code input devices. This can be done, for example, by simple observation or by manipulation of the keypad. The actual weak point of these code entry devices is the keypad.
- a combination lock is known from EP-A-0 361 881, in which the code number to be set can be entered by means of a turntable.
- the multi-digit initial value is specified by a random generator, so that also When observing the adjustment angle of the turntable, no conclusions can be drawn about the set code character.
- the use of multi-digit code elements offers a relatively high level of security even for code words consisting of a few code elements, but counting up or down is correspondingly time-consuming for a user.
- the invention is based on the object of specifying a code input device of the type mentioned at the outset which prevents the code from being ascertained by preparing the actuating device and / or by observing the sequence by an unauthorized person.
- This object is achieved in that the code characters are reproduced in a sequence which is predetermined independently of the user and under the control of the processing unit on the display device, and in that when an appropriate code element is reproduced, the user confirms the actuation device.
- a basic idea of the invention is therefore that a "search run" for the individual code characters, which cannot be reconstructed or reconstructed from the outside, is carried out, which can only be followed by the authorized person on the display. Since the display is volatile, ie leaves no traces, subsequent reconstruction of the characters themselves and their order is impossible. For the same reason, an assignment to the character concerned is excluded if the character confirmation is carried out by the user. In other words, the actuating device does not assume an evaluable position when it is used to enter a correct code element, so that manipulation of the Actuator or a preparation is futile.
- an operating element for switching on is available.
- the user can therefore determine the time himself, so that the risk of input errors is reduced.
- the user-controlled switching helps to further increase the security because the operation of the input device is even more randomly dependent due to the lack of fixed cycle times.
- Another aspect of the invention is that a random generator or the like. is present, which defines a new code character initial value each time the code input device is started up.
- a structurally simple and easy-to-use actuating device consists in that it consists of a switch having at least three switching states, one switching state being the "ready" position and in the other two switching states the code character advancement or code character confirmation taking place.
- the switch is preferably designed as a rocker switch or as a rotary knob with a switching lug and two switching contacts interacting with it.
- the security of the code input device is ensured in that only one position of the total code is shown on the display device. After confirmation of a code sign, it is deleted according to the invention and replaced by a neutral symbol. This advantageous measure prevents the code from being ascertained by briefly observing the display panel once, for example in combination with manipulation of the switching devices.
- a particularly advantageous embodiment is the use of three pushbutton switches as switching devices of the actuating device.
- One key switch is used for counting down the code characters, another for counting up the code characters and the third for confirming an appropriate code character. This arrangement ensures particularly clear and quick operability.
- the display device can be inactive in an equally advantageous embodiment in the basic state and can be activated by actuating the actuating device, for example the push-button switch used to confirm an appropriate code character.
- the code input device acc. Fig. 1 is used to control an electric door lock for a security container, such as a safe.
- the example of an input device according to FIG. 1 comprises, in addition to three push buttons 17, 18 and 19, a multi-digit and multi-line display device 4. Two lines each with 13 digits are shown here by way of example. It is an LED sign display for the display of letters, numbers and symbols, which is covered by a privacy film and is protected against lateral view.
- the display is deactivated in the basic state. If the key switch 19 is pressed, an operating instruction or information for the user appears, here the instruction "enter code”. A first digit generated by the random number generator is also reproduced. By pressing the key switch 17 or 18, the operator can enter the appropriate digit of his code word by counting up or down and confirm it with the key switch 19. If this process is carried out correctly, the Number deleted from the display and indicated by a symbol, here the symbol "*". In this way, the operator has control over which part of his code word is currently being checked. In Fig. 1, three symbols "*" indicate that three code digits have already been entered correctly and that the fourth digit is currently waiting to be checked.
- any other instructions can of course be given to the operator, such as "repeat entry” or the like.
- the display device 4 can be used for other displays, for example for displaying the real time or the last use of the code input device, etc.

Description
Die Erfindung betrifft eine Code-Eingabevorrichtung für eine vorgegebene Menge von Codezeichen, beispielsweise für eine Zutritts- oder Berechtigungskontrollvorrichtung, mit einer Betätigungsvorrichtung, einer elektronischen Verarbeitungseinheit und einer Anzeigevorrichtung.The invention relates to a code input device for a predetermined set of code characters, for example for an access or authorization control device, with an actuating device, an electronic processing unit and a display device.
Um zu verhindern, daß sich unberechtigte Personen Zutritt zu gesicherten Räumen verschaffen oder Geräte und Vorrichtungen in Gebrauch nehmen, die nur autorisierten Benutzern vorbehalten sind, werden bekanntlich Kontrollvorrichtungen eingesetzt, in welche der Benutzer einen codierten Berechtigungsnachweis eingeben muß. Eine elektronische Verarbeitungseinheit überprüft den Code und bewirkt eine Freigabe nur dann, wenn die vorgegebenen Codezeichen in der richtigen Reihenfolge eingegeben werden. Sehr weit sind Tastaturen zum Eintippen der Codezeichen verbreitet. Wenngleich sie sich sehr gut bewährt haben, ist nicht ausgeschlossen, daß die eingegebenen Codezeichen anhand von Fingerabdrücken mißbräuchlich identifiziert werden und daß die Berechtigungsidentifikation auf diese Weise von einem Unberechtigten rekonstruiert wird.In order to prevent unauthorized persons from gaining access to secure rooms or from using devices and devices that are only reserved for authorized users, control devices are known to be used in which the user must enter a coded proof of authorization. An electronic processing unit checks the code and only releases it if the specified code characters are entered in the correct order. Keyboards for typing code characters are very common. Although they have proven themselves very well, it cannot be ruled out that the entered code characters will be misused using fingerprints and that the authorization identification will be reconstructed in this way by an unauthorized person.
Es ist ferner aus der DE-A-39 00 434 im Zusammenhang mit einem elektronischen Schloß bekannt, die Codeeingabe mit Hilfe eines kombinierten Dreh- und Drücksteuerknopfes auszuführen. Die einzelnen Codezeichen sind festen Drehwinkeln zugeordnet und werden dadurch eingegeben, daß der Steuerknopf zunächst entsprechend gedreht und dann gedrückt wird. Das jeweilige Codezeichen wird optisch in einem Sichtfenster angezeigt. Bei dieser Vorrichtung besteht die Gefahr, daß selbst bei neutralem Steuerknopf die einzelnen Knopfstellungen durch manipulatives Anbringen einer versteckten Positionsmarke erkennbar gemacht werden.It is also known from DE-A-39 00 434 in connection with an electronic lock, the code entry with the aid of a combined rotary and push control button to execute. The individual code characters are assigned fixed rotation angles and are entered by first turning the control button accordingly and then pressing. The respective code symbol is visually displayed in a viewing window. With this device, there is a risk that even with a neutral control button, the individual button positions can be made recognizable by manipulative attachment of a hidden position mark.
Seit langem sind elektronische Eingabevorrichtungen für einen Code bekannt, welche ein Tastenfeld zum Eintippen des Codes aufweisen. Derartige Eingabevorrichtungen mit Tastenfeld sind für einen Benutzer einfach zu bedienen, da er die einzelnen Codezeichen des Codes auf der Tastatur sieht und nur die entsprechenden Tasten in der zutreffenden Reihenfolge zu tippen braucht.Electronic input devices for a code have long been known, which have a keypad for entering the code. Such input devices with a keypad are easy to use for a user, since he sees the individual code characters of the code on the keyboard and only has to type the corresponding keys in the correct order.
Es hat sich jedoch gezeigt, daß bei diesen Codeeingabevorrichtungen der Berechtigungscode bei betrügerischer Absicht relativ leicht zu ermitteln ist. Dies kann beispielsweise durch einfaches Beobachten oder durch Manipulation des Tastenfeldes geschehen. Die eigentliche Schwachstelle dieser Codeeingabevorrichtungen bildet hierbei das Tastenfeld.However, it has been found that the authorization code can be determined relatively easily in the case of fraudulent intent with these code input devices. This can be done, for example, by simple observation or by manipulation of the keypad. The actual weak point of these code entry devices is the keypad.
Diese Schwachstelle ist bei der Codeeingabevorrichtung gemäß US-A-3,812,403 durch Verwendung einer Betätigungsvorrichtung vermieden. Durch Drücken der Betätigungsvorrichtung für eine bestimmte Zeitdauer wird auf einer einstelligen Anzeigevorrichtung ein Codezeichen gegeben. Das angezeigte Codezeichen ist dabei von der Zeitdauer des Drükkens der Betätigungsvorrichtung abhängig.This weak point is avoided in the code input device according to US-A-3,812,403 by using an actuating device. By pressing the actuating device for a certain period of time, a code sign is given on a single-digit display device. The code symbol displayed depends on the length of time the actuating device is pressed.
Obwohl bei dieser bekannten Codeeingabevorrichtung kein Tastenfeld verwendet wird, besteht auch hier die Gefahr darin, daß durch einfaches Beobachten der Betätigungseinrichtung während der Codeeingabe der Berechtigungscode ermittelt werden kann.Although no keypad is used in this known code entry device, there is also the danger here that the authorization code can be determined by simply observing the actuating device during code entry.
Aus der EP-A-0 361 881 ist ein Zahlenschloß bekannt, bei dem die einzustellende Codezahl mittels einer Drehscheibe eingegeben werden kann. Der mehrstellige Anfangswert wird dabei durch einen Zufallsgenerator vorgegeben, so daß auch bei Beobachtung des Verstellwinkels der Drehscheibe keine Rückschlüsse auf das eingestellte Codezeichen gezogen werden können. Die Verwendung mehrstelliger Codeelemente bietet zwar auch bei Codewörtern aus wenigen Codeelementen eine relativ hohe Sicherheit, jedoch ist das Vorwärts- oder Rückwärtszählen für einen Benutzer entsprechend zeitaufwendig.A combination lock is known from EP-A-0 361 881, in which the code number to be set can be entered by means of a turntable. The multi-digit initial value is specified by a random generator, so that also When observing the adjustment angle of the turntable, no conclusions can be drawn about the set code character. The use of multi-digit code elements offers a relatively high level of security even for code words consisting of a few code elements, but counting up or down is correspondingly time-consuming for a user.
Bei Vorrichtungen mit Codewörtern, die aus einstelligen Codeelementen zusammengesetzt sind, wird eine hohe Sicherheit durch eine entsprechend große Anzahl von Stellen für Codeelemente erreicht. Bei den oben beschriebenen Vorrichtungen muß ein Benutzer ausgehend von der auf der Anzeige vorgegebenen Anfangs zahl durch Vorwärts- oder Rückwärtsschalten die jeweils zutreffende Codenummer eingeben. Bei den bekannten Vorrichtungen muß der Benutzer stets im Gedächtnis behalten, an welcher Stelle des Codes er gerade das Codeelement eingibt. Vor allem bei vielstelligen Codewörtern kann es leicht vorkommen, daß der Benutzer nicht mehr sicher weiß, ob er gerade das Codelement für beispielsweise die sechste oder die siebte Stelle eingibt.In devices with code words that are composed of single-digit code elements, high security is achieved by a correspondingly large number of digits for code elements. In the devices described above, a user must enter the applicable code number based on the initial number specified on the display by switching forward or backward. In the known devices, the user must always keep in mind at which point of the code he is entering the code element. Especially with multi-digit code words, it can easily happen that the user no longer knows whether he is entering the code element for the sixth or seventh digit, for example.
Bei den bekannten Vorrichtungen kann es daher leicht zu Fehleingaben kommen, welche eine zeitaufwendige erneute Eingabe der gesamten Codenummer durch den Benutzer erfordern oder bei Einbau einer entsprechenden Sperrvorrichtung bei ein- oder mehrmaliger versehentlicher Falscheingabe dem berechtigten Benutzer der Zutritt verweigert wird.In the known devices, incorrect entries can therefore easily occur, which require a time-consuming re-entry of the entire code number by the user or, if a corresponding blocking device is installed, the authorized user is refused access if one or more accidental incorrect entries are made.
Der Erfindung liegt die Aufgabe zugrunde, eine Code-Eingabevorrichtung der eingangs genannten Art anzugeben, die verhindert, daß durch Präparierung der Betätigungsvorrichtung und/oder durch Beobachtung des Ablaufs durch einen Unberechtigten die Ermittlung des Codes möglich ist.The invention is based on the object of specifying a code input device of the type mentioned at the outset which prevents the code from being ascertained by preparing the actuating device and / or by observing the sequence by an unauthorized person.
Diese Aufgabe wird dadurch gelöst, daß die Codezeichen in einer benutzerunabhängig vorgegebenen Reihenfolge unter Steuerung der Verarbeitungseinheit auf der Anzeigevorrichtung wiedergegeben werden und daß bei der Wiedergabe eines zutreffenden Codeelements eine Bestätigung durch den Benutzer über die Betätigungsvorrichtung vorgenommen wird.This object is achieved in that the code characters are reproduced in a sequence which is predetermined independently of the user and under the control of the processing unit on the display device, and in that when an appropriate code element is reproduced, the user confirms the actuation device.
Ein Grundgedanke der Erfindung besteht demnach darin, daß ein von außen nicht nachvollziehbarer oder rekonstruierbarer "Suchlauf" für die einzelnen Codezeichen durchgeführt wird, der ausschließlich vom Berechtigten an der Anzeige verfolgt werden kann. Da die Anzeige flüchtig ist, d.h. keine Spuren hinterläßt, ist eine nachträgliche Rekonstruktion der Zeichen selbst und ihre Reihenfolge ausgeschlossen. Aus dem gleichen Grund ist eine Zuordnung zum betreffenden Zeichen ausgeschlossen, wenn die Zeichenbestätigung vom Benutzer vorgenommen wird. Anders ausgedrückt bedeutet dies, daß die Betätigungsvorrichtung keine auswertbare Stellung einnimmt, wenn sie zur Eingabe eines richtigen Codeelementes benutzt wird, so daß eine Manipulation an der Betätigungsvorrichtung oder eine Präparierung zwecklos ist.A basic idea of the invention is therefore that a "search run" for the individual code characters, which cannot be reconstructed or reconstructed from the outside, is carried out, which can only be followed by the authorized person on the display. Since the display is volatile, ie leaves no traces, subsequent reconstruction of the characters themselves and their order is impossible. For the same reason, an assignment to the character concerned is excluded if the character confirmation is carried out by the user. In other words, the actuating device does not assume an evaluable position when it is used to enter a correct code element, so that manipulation of the Actuator or a preparation is futile.
Besonders zweckmäßig ist es, daß ein Bedienelement zur Weiterschaltung vorhanden ist. Der Benutzer kann daher die Zeit selbst bestimmen, so daß die Gefahr von Eingabefehlern verringert wird. Außerdem trägt das benutzergesteuerte Weiterschalten dazu bei, daß die Sicherheit noch weiter erhöht wird, weil die Bedienung der Eingabevorrichtung mangels fester Zykluszeiten noch zufallsabhängiger ist.It is particularly expedient that an operating element for switching on is available. The user can therefore determine the time himself, so that the risk of input errors is reduced. In addition, the user-controlled switching helps to further increase the security because the operation of the input device is even more randomly dependent due to the lack of fixed cycle times.
Ein weiterer Aspekt der Erfindung besteht darin, daß ein Zufallsgenerator o.ä. vorhanden ist, welcher bei jeder Inbetriebnahme der Code-Eingabevorrichtung einen neuen Codezeichen-Anfangswert festlegt.Another aspect of the invention is that a random generator or the like. is present, which defines a new code character initial value each time the code input device is started up.
Es ist ein Umschalter vorhanden, mit welchem die Fortschaltung in Auf- oder Abwärtsrichtung vom Bediener vorgenommen werden kann.There is a changeover switch with which the operator can switch up or down.
Eine konstruktiv einfache und leicht bedienbare Betätigungsvorrichtung besteht darin, daß sie aus einem mindestens drei Schaltzustände aufweisenden Schalter besteht, wobei ein Schaltzustand die "Bereit"-Stellung ist und in den beiden anderen Schaltzuständen die Codezeichen-Weiterschaltung bzw. die Codezeichen Bestätigung erfolgt. Der Schalter ist bevorzugt als Wipp Schalter oder als Drehknopf mit einer Schaltnase und zwei damit zusammenwirkenden Schaltkontakten ausgebildet.A structurally simple and easy-to-use actuating device consists in that it consists of a switch having at least three switching states, one switching state being the "ready" position and in the other two switching states the code character advancement or code character confirmation taking place. The switch is preferably designed as a rocker switch or as a rotary knob with a switching lug and two switching contacts interacting with it.
Hierbei wird erfindungsgemäß die Sicherheit der Codeeingabevorrichtung dadurch gewährleistet, daß nur eine Stelle des Gesamtcodes auf der Anzeigevorrichtung dargestellt wird. Nach Bestätigung eines Codezeichens wird dieses erfindungsgemäß gelöscht und durch ein neutrales Symbol ersetzt. Durch diese vorteilhafte Maßnahme wird verhindert, daß durch einmaliges kurzes Beobachten des Anzeigefeldes etwa in Kombination mit einer Manipulation der Schalteinrichtungen der Code ermittelt werden kann.According to the invention, the security of the code input device is ensured in that only one position of the total code is shown on the display device. After confirmation of a code sign, it is deleted according to the invention and replaced by a neutral symbol. This advantageous measure prevents the code from being ascertained by briefly observing the display panel once, for example in combination with manipulation of the switching devices.
Eine besonders vorteilhafte Ausführungsform ist die Verwendung von drei Tastschaltern als Schalteinrichtungen der Betätigungsvorrichtung. Ein Tastschalter dient zum Rückwärtszählen der Codezeichen, ein weiterer zum Vorwärtszählen der Codezeichen und der dritte zum Bestätigen eines zutreffenden Codezeichens. Mit dieser Anordnung ist eine besonders übersichtliche und schnelle Bedienbarkeit gewährleistet.A particularly advantageous embodiment is the use of three pushbutton switches as switching devices of the actuating device. One key switch is used for counting down the code characters, another for counting up the code characters and the third for confirming an appropriate code character. This arrangement ensures particularly clear and quick operability.
Eine weitere wesentliche Bedienungserleichterung wird durch eine vorteilhafte Ausführungsform mit zusätzlichen Stellenanzeigen gewährleistet. Diese Stellenanzeigen geben eine Betriebsanleitung oder Informationen an. Im Zusammenspiel mit der Betätigung der Betätigungsvorrichtung ergibt sich in dieser Ausführungsform eine interaktive Benutzung.A further essential ease of operation is ensured by an advantageous embodiment with additional job advertisements. These job advertisements provide operating instructions or information. In interaction with the actuation of the actuation device, this embodiment results in an interactive use.
Zur weiteren Steigerung der Sicherheit und zur Verbesserung der Wirtschaftlichkeit kann die Anzeigevorrichtung in einer ebenfalls vorteilhaften Ausführungsform im Grundzustand inaktiv sein und durch Betätigung der Betätigungsvorrichtung, beispielsweise dem der Bestätigung eines zutreffenden Codezeichens dienenden Tastschalter, aktiviert werden.To further increase security and to improve economy, the display device can be inactive in an equally advantageous embodiment in the basic state and can be activated by actuating the actuating device, for example the push-button switch used to confirm an appropriate code character.
Weiterhin wird eine besonders gute Übersichtlichkeit erreicht, wenn die zusätzlichen Stellenanzeigen in einer zusätzlichen Zeile angeordnet sind.Furthermore, a particularly good clarity is achieved if the additional job advertisements are arranged in an additional line.
Nachfolgend wird die Erfindung anhand von einem in der Zeichnung dargestellten Ausführungsbeispiel weiter beschrieben.

- zeigt schematisch eine Draufsicht auf eine Code-Eingabevorrichtung;
- Fig. 1
- schematically shows a plan view of a code input device;
Die Code-Eingabevorrichtung gem. Fig. 1 dient zur Ansteuerung eines elektrischen Türschlosses für ein Sicherheitsbehältnis, beispielsweise einen Tresor.The code input device acc. Fig. 1 is used to control an electric door lock for a security container, such as a safe.
Das Beispiel für eine Eingabevorrichtung gemäß Fig. 1 umfaßt neben drei Tastschaltern 17,18 und 19, eine mehrstellige und mehrzeilige Anzeigevorrichtung 4. Es sind hier beispielhaft zwei Zeilen mit jeweils 13 Stellen dargestellt. Dabei handelt es sich um eine LED-Zeichenanzeige zur Wiedergabe von Buchstaben, Ziffern und Symbolen, die durch eine Sichtschutz-Folie abgedeckt und gegen seitliche Sicht geschützt ist.The example of an input device according to FIG. 1 comprises, in addition to three
Im Grundzustand ist die Anzeige inaktiviert. Wenn der Tastschalter 19 gedrückt wird, erscheint eine Bedienungsanweisung oder eine Information für den Benutzer, hier die Anweisung "Code eingeben". Außerdem wird eine erste, vom Zufallsgenerator erzeugte Ziffer wiedergegeben. Durch Drücken der Tastschalter 17 oder 18 kann der Bediener durch Vorwärts- oder Zurückzählen die zutreffende Ziffer seines Codewortes eingeben und mit dem Tastschalter 19 bestätigen. Wird dieser Vorgang richtig ausgeführt, so wird die Ziffer in der Anzeige gelöscht und durch ein Symbol, hier das Symbol "*", angezeigt. Auf diese Weise hat der Bediener eine Kontrolle darüber, welche Stelle seines Codewortes im Moment überprüft wird. In der Fig. 1 wird durch drei Symbole "*" angezeigt, daß bereits drei Codeziffern richtig eingegeben wurden und daß gerade die vierte Stelle zur Überprüfung ansteht.The display is deactivated in the basic state.
