Abstract

The system has three, four or multi-digit codes, whose position contains numeric and/or letters and/or special characters.

Description

Die Erfindung betrifft ein System zum Verschlüsseln von Daten und insbesondere einen Geheimcode.The The invention relates to a system for encrypting data, and more particularly a secret code.

Derartige Geheimcodes bestehen im allgemeinen aus vier Ziffern die beispielsweise als sogenannte Pin-Codes für Scheckkarten oder dergleichen verwendet werden. Nachteilig ist hierbei, daß derartige Codes, die aus drei oder meistens nur vier Ziffern bestehen, leicht durch Probieren entschlüsselt werden können.such Secret codes generally consist of four digits, for example as so-called pin codes for Check cards or the like can be used. The disadvantage here is that such Codes that consist of three or mostly four digits, easily decrypted by trial and error can be.

Der Erfindung liegt die Aufgabe zugrunde, ein System zur Verfügung zu stellen, das nahezu sicher gegen den Gebrauch durch Unbefugte ist.Of the Invention has for its object to provide a system available safe against use by unauthorized persons.

Zur Lösung der Aufgabe ist erfindungsgemäß ein drei-, vier- oder mehrstelliger Code vorgesehen, dessen Stellen Ziffern und/oder Buchstaben und/oder Sonderzeichen enthalten. Der Vorteil dieser Lösung besteht darin, daß ein derartiger Code nahezu unmöglich geknackt werden kann, da die Kombinationsmöglichkeiten weitaus größer sind als bei bisherigen Zifferncodes, weil der Zeichenvorrat zusätzlich zu den zehn Ziffern auch alle 26 Buchstaben des Alphabets und eine nahezu unbegrenzte Zahl von Sonderzeichen enthält. Das System eignet sich insbesondere für Kreditkarten oder dergleichen.to solution the object is according to the invention a three, four or more digit code provided, whose digits digits and / or letters and / or special characters. The advantage this solution is that a such code almost impossible can be cracked because the combination options are much larger as with previous digit codes, because the character set in addition to the ten digits also all 26 letters of the alphabet and one contains almost unlimited number of special characters. The system is suitable especially for Credit cards or the like.

Die Erfindung ist beigefügt an einigen Beispielen erläutert, die in der Zeichnung dargestellt sind. Daraus ergibt sich, daß nicht nur die Kombinationsmöglichkeit von Zahlen und Buchstaben vorhanden ist, sondern auch mit den unterschiedlichsten Sonderzeichen, von denen in der Zeichnung nur einige ausgewählt sind.The Invention is attached explained with some examples, which are shown in the drawing. It follows that not only the possibility of combination of numbers and letters, but also with a variety of special characters, only a few of which are selected in the drawing.
