Abstract

According to the invention, the person seeking access, in whom there has been a variation of personal features of which he is aware in relation to a feature set stored in a security encoding device and assigned individually to him, enters in the security encoding system, in addition to originally fixed information on the personal features, information on the feature variation. The security encoding device cancels the part of the feature set to which the feature variation relates and, if appropriate, allows access. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein-Verfahren zur Verringerung der Rate falscher Zurückweisungen in einem Sicherheits- und Schlüsselsystem, das persönliche Merkmale der Zutrittsuchenden zur Verifikation verwendet.The present invention relates to a method for reducing the rate of false rejections in a security and key system that uses personal characteristics of the access seeker for verification.

Werden persönliche Merkmale zur automatischen Verifikation von Personen verwendet, so dürfen diese bei den heute bekannten,Systemen nicht abgeändert werden, da die betreffende Einrichtung nicht mehr genügend Übereinstimmung zwischen dem gespeicherten Merkmalssatz und der zur Verifikation angebotenen Information findet. Veränderungen der persönlichen Merkmale führen demnach zu einer erhöhten Rate von falschen Zurückweisungen (die richtige Person wird als nicht erkannt zurückgewiesen), aufgrund derer solche Sicherungs- und Schlüsseleinrichtungen für viele Anwendungen unattraktiv werden.If personal characteristics are used for the automatic verification of persons, these must not be changed in the systems known today, since the device in question no longer finds sufficient correspondence between the stored characteristic set and the information offered for verification. Changes in personal characteristics therefore lead to an increased rate of false rejections (the right person is rejected as not recognized), which makes such security and key devices unattractive for many applications.

Aus den persönlichen Merkmalen des Zutrittsuchenden wird in aller Regel ein redundanter Merkmalssatz zusammengestellt. Während einige Änderungen der persönlichen Merkmale für die jeweilige Person mehr oder weniger unbewußt auftreten (leichte Änderung der Spracheigenschaften oder die charakteristischen Eigenschaften der Unterschrift im Laufe der Zeit u.a.m.), gibt es andere, die von der jeweiligen Person erkannt werden bzw. von ihr sogar selbst vorgenommen werden, beispielsweise Veränderung der Stimme durch Gemütsbewegungen oder Krankheit, Aufsetzen einer Brille, Anstecken eines Ringes usw.. Wird beispielsweise die Handgeometrie vermessen, so kann die Zurückweisung bereits durch das Tragen eines Ringes, der bei der Aufnahme des Merkmalssatzes nicht getragen wurde, erfolgen.A redundant set of characteristics is usually compiled from the personal characteristics of the access seeker. While some changes in the personal characteristics of the person appear more or less subconsciously (slight change in language characteristics or the characteristic properties of the signature over time, etc.), there are others that are recognized by the person or even by himself be made, for example, changing the voice due to mood movements or illness, putting on glasses, putting on a ring, etc. Will, for example the hand geometry is measured, the rejection can already be done by wearing a ring that was not worn when the set of characteristics was recorded.

Die derzeit bekannten Sicherheits- und Schlüsselsysteme reagieren auf derartige Merkmalsveränderungen sehr empfindlich.The currently known security and key systems are very sensitive to such changes in characteristics.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Verringerung der Rate falscher Zurückweisungen in einem Sicherheits- und Schlüsselsystem, das persönliche Merkmale der Zutrittsuchenden zur Verifikation verwendet, zu schaffen.The present invention has for its object to provide a method for reducing the rate of false rejections in a security and key system that uses personal characteristics of the access seekers for verification.

Die der Erfindung zugrundeliegende Aufgabe wird durch ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 gelöst, das durch die in dem kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale charakterisiert ist.The object on which the invention is based is achieved by a method according to the preamble of patent claim 1, which is characterized by the features specified in the characterizing part of patent claim 1.

Die Erfindung bietet den Vorteil, daß das Sicherheits- und Schlüsselsystem gegenüber Fälschungsversuchen nicht merkbar empfindlicher wird, da nur ein geringer Teil des Merkmalssatzes für die Verifizierung entfällt.The invention has the advantage that the security and key system is not noticeably more sensitive to attempts at forgery, since only a small part of the set of features is omitted for verification.

Vorteilhafte Weiterbildungen der Erfindung sind durch die in den Unteransprüchen angegebenen Merkmale gekennzeichnet.Advantageous developments of the invention are characterized by the features specified in the subclaims.

Im folgenden wird die Erfindung anhand einer Figur, die lediglich ein Ausführungsbeispiel für ein Sicherheits-und Schlüsselsystem zur Durchführung des erfindungsgemäßen Verfahrens zeigt, im einzelnen erläutert.The invention is explained in detail below with reference to a figure which shows only one exemplary embodiment of a security and key system for carrying out the method according to the invention.

Wie die Figur zeigt, besteht ein derartiges, zur Durchführung des erfindungsgemäßen Verfahrens geeignetes Sicherheits- und Schlüsselsystem 1 im wesentlichen aus einer Sicherheits- und Schlüsseleinrichtung 11 und einer Eingabeeinrichtung 12. Der Zutrittsuchende Z gibt eine Information über seine persönlichen Merkmale IpM in die Eingabeeinrichtung 12 ein, die diese an die Sicherheits- und Schlüsseleinrichtung 11 ggf. in aufbereiteter Form weiterleitet. In der Sicherheits- und Schlüsseleinrichtung 11 sind alle notwendigen Merkmalssätze MMS der Zutrittsberechtigten gespeichert. Zusätzlich ist neben dem eigentlichen Sicherheits- und Schlüsselsystem 1 erfindungsgemäß eine Hilfseingabeeinrichtung 2 vorgesehen, über die eine Information über die Merkmalsveränderung einer zutrittsuchenden Person eingebbar ist.As the figure shows, such a security and key system 1, which is suitable for carrying out the method according to the invention, essentially consists of one Security and key device 11 and an input device 12. The access seeker Z enters information about his personal features IpM into the input device 12, which forwards it to the security and key device 11, if necessary, in a processed form. In the security and key device 11, all the necessary feature sets MMS of the authorized users are stored. In addition to the actual security and key system 1, an auxiliary input device 2 is provided according to the invention, via which information about the change in characteristics of an access-seeking person can be entered.

Für das erfindungsgemäße Verfahren ist vorgesehen, daß von dem Zutrittsuchenden Z, bei dem gegenüber einem in der Sicherheits- und Scblüsseleinrichtung 11 gespeicherten und ihm individuell zugeteilten Merkmalssatz MMS eine ihm bewußte Veränderung seiner persönlichen Merkmale eingetreten ist, zusätzlich zu einer ursprünglich festgelegten Information über die persönlichen Merkmale IPM eine Information über die Merkmalsveränderung IMV in das Sicherheits-und Schlüsselsystem 1 über die Hilfseingabeeinrichtung 2 eingegeben wird. Außerdem ist erfindungsgemäß vorgesehen, daß die Sicherheits- und Schlüsseleinrichtung 11 den von den Merkmalsveränderung betroffenen Teil.des Merknrals-satzes MMS unterdrückt und den Zutritt ggf. freigibt.For the method according to the invention it is provided that the access seeker Z, in which a conscious change in his personal characteristics has occurred in relation to a set of features MMS stored in the security and encryption device 11 and individually assigned to him, in addition to an originally defined information about the personal Features I PM information about the change in features I MV is entered into the security and key system 1 via the auxiliary input device 2. In addition, it is provided according to the invention that the security and key device 11 suppresses the part of the feature set MMS affected by the change in features and, if necessary, releases the access.

Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Sicherheits- und Schlüsseleinrichtung 11 anstelle des betroffenen Merkmalssatzes MMS einen modifizierten, vorzugsweise durch einen Rechner (nicht gezeigt) erstellten Merkmalssatz MMS' verwendet.An advantageous development of the invention provides that the security and key device 11 uses a modified feature set MMS ', preferably created by a computer (not shown), instead of the feature set MMS concerned.

Durch äußere Bedingungen verursachte Änderungen der charakteristischen Merkmale können vorteilhafterweise ebenfalls von einem derartigen System mittels des erfindungsgemäßen Verfahrens berücksichtigt werden. So können beispielsweise Veränderungen von Unterschriften, die aufgrund des verwendeten Schreibgerätes (Füllfederhalter, Kugelschreiber, Bleistift) auftreten, durch Eingabe der Merkmale des jeweils verwendeten Schreibgerätes kompensiert werden. Das Sicherheits- und Schlüsselsystem zieht dann jeweils den entsprechenden Merkmalssatz zur Verifikation heran.Changes in the characteristic features caused by external conditions can advantageously also be flat if taken into account by such a system using the method according to the invention. For example, changes in signatures that occur due to the writing instrument used (fountain pen, ballpoint pen, pencil) can be compensated for by entering the characteristics of the writing instrument used in each case. The security and key system then uses the corresponding feature set for verification.
