Abstract

Method for input of an authentication code in which a sequence of images are displayed on a display device with each image displayed for a limited time duration. Each image or part of an image has a code assigned to it. The authentication code is calculated from the image codes or a time value. As an example, if a user wishes to enter a PIN or password an array of ten images are portrayed on a screen. The user knows which image is associated with which number of letter and so simply clicks on a sequence of images to enter a PIN or password.

Description

Die Erfindung betrifft ein Verfahren zur Eingabe eines Au­ thentifizierungscodes.The invention relates to a method for entering an Au thentifizierungscodes.

Ein solcher Authentifizierungscode ist beispielsweise ein Passwort oder eine persönliche Identifizierungsnummer (PIN). Ein solcher Code wird im Allgemeinen über eine Tastatur ein­ gegeben.Such an authentication code is, for example Password or a personal identification number (PIN). Such code is generally entered using a keyboard given.

Probleme bei dieser Methode sind zum Einen das unbeobachtete Eingeben des Codes und zum Anderen das Merken desselben.On the one hand, problems with this method are the unobserved Enter the code and secondly memorize it.

Der Erfindung liegt die Aufgabe zugrunde, ein einfaches und sicheres Eingabeverfahren für einen Authentifizierungscode anzugeben.The invention has for its object a simple and secure entry method for an authentication code specify.

Diese Aufgabe wird erfindungsgemäß durch die im Patentan­ spruch angegebenen Merkmale gelöst.This object is achieved by the in patent characteristics specified resolved.

Im Folgenden wird die Erfindung anhand eines Ausführungsbei­ spieles beschrieben.In the following, the invention is illustrated by means of an embodiment game described.

Das erfindungsgemäße Eingabeverfahren ermöglicht eine kreati­ ve und personalisierbare Zugangssicherung.The input method according to the invention enables creativity ve and customizable access security.

Die Erfindung geht aus von einem visuellen Eingabemechanis­ mus. Bei diesem werden die alphanumerischen Zeichen des Au­ thentifizierungscodes durch Bilder ersetzt. Auf dem Bild­ schirm werden beispielsweise zehn Bilder dargestellt, wobei jedem der Bilder ein Buchstabe beziehungsweise eine Ziffer zugeordnet ist. Der Benutzer weiss welche Bilder er in wel­ cher Reihenfolge anklicken muss, um so den entsprechenden Co­ de einzugeben. Der Benutzer kann hierzu persönliche Bilder verwenden, was die Merkbarkeit erleichtert. The invention is based on a visual input mechanism mus. With this the alphanumeric characters of the Au Identification codes replaced by pictures. In the picture For example, ten images are shown on the screen a letter or a number for each of the pictures assigned. The user knows which pictures he in which order must be selected in order to select the corresponding Co de to enter. The user can use personal pictures use, which makes it easier to remember.  

Erfindungsgemäß wird eine Bildsequenz, das heisst eine Auf­ einanderfolge von Bildern auf der Anzeigeeinrichtung darge­ stellt. Auch hier ist wieder jedem der Bilder ein alphanume­ risches Zeichen zugeordnet. Es kann dabei ein Videofilm ver­ wendet werden, oder auch im einfachsten Fall eine Folge von unabhängigen Standbildern. Jedes der Bilder erscheint bei­ spielsweise für eine Sekunde, und kann während dieser Zeit­ spanne durch Anklicken ausgewählt werden. Durch die Auswahl wird das diesem Bild zugeordnete Zeichen für die Eingabe des Authentifizierungscodes aktiviert.According to the invention, an image sequence, that is an opening sequence of images on the display device Darge provides. Again, each of the pictures is an alphanume assigned character. It can ver a video be used, or in the simplest case a sequence of independent still images. Each of the images appears on for example for a second, and can during that time span can be selected by clicking. By selection the character assigned to this image for entering the Authentication codes activated.

Bei einer Weiterbildung der Erfindung ist nur ein Bildteil aktivierbar. Dieser Teil ist beispielsweise durch seine Koor­ dinaten gegeben, die einen Code darstellen. Dieser Code wird, bei einer weiter Ausgestaltung der Erfindung zusammen mit ei­ nem Zeitwert, bei einer Berechnung des Authentifizierungsco­ des verwendet. Der Zeitwert kann durch die Anzeigedauer des betreffenden Bildes gegeben sein.In a further development of the invention there is only one part of the picture enableable. This part is, for example, by its Koor given data that represent a code. This code will in a further embodiment of the invention together with egg time value, when calculating the authentication co of the used. The time value can be determined by the duration of the display given picture.

Weiter kann bei der Berechnung des Authentifizierungscodes noch ein Verschlüsselungsalgorithmus eingesetzt werden.You can continue to calculate the authentication code an encryption algorithm can be used.

Durch die zeitliche Einschränkung wird die Sicherheit bei der Codeeingabe erhöht.Due to the time limitation, security at Code entry increased.
