DE4423415A1 - Authentication method using person-specific psychometric data (PSPI) - Google Patents

Abstract

The method uses (PSPI) in the form of images, tokens, texts, or sounds for identification, based on individual knowledge and experiences. The PSPI items are subdivided into elements which are assembled and registered within a memory, having kept inaccessible. The elements are then made available, some in a determined sequence and others in a random sequence, before being assembled into characteristic two-dimensional structures or linear chains. Associated elements are connected to form reconstituted PSPI in a sequence which is defined by the way in which they were registered. The PSPI data may also consist of statements with correlated verification or falsification data.

Description

In German patent application P 44 16 665.6 there is a psychometric authenticator, that is, a facility to verify the identity, authenticity, authenticity of Disclosed people based on the psychometric principle. There is also reference to the possibility of the principle of manufacturing psychometric authenticator cryptographic notebooks and electronic To use key systems. Subject of the present Invention is a psychometric authenticator after Claim 1.

A first embodiment of the invention, a personal secret code card, is described in claim 2 and shown in Fig. 1 using a specific example.

On a card or a sheet, ten pairs of text AB from terms that are only rememberable by the owner, preferably names and associated first names, are entered within two text columns, in such a way that related names Ax and first name Bx are separated from one another in as irregular a manner as possible (to illustrate the Invention, the names and first names of people in contemporary history are used in Fig. 1, who of course do not meet the basic psychometric criteria of exclusive individual knowledge). Eight double columns with characters are arranged between these two word columns, preferably with letters and numbers, from which eight secret codes (PIN 1 to PIN 8) result. These middle columns of characters contain 5 digit codes under PIN 1 to PIN and 8 letter codes under PIN 6 to PIN. To reconstruct the eight codes, the cardholder associates the names with the first names (known only to him in practice) in the first half of the right column within the right half of the, as indicated in the left half of the double columns by letters or numbers Double columns to the numbers or letters that make up the secret code. In the example, the codes are: PIN 1 = 36 29; PIN 2 = 29 26; PIN 3 = 27 305; PIN 4 = 69 11 37; PIN 5 = 57 06 27 98 18; PIN 6 = EGM ZUC; PIN 7 = GQA REH DZ; PIN 8 = AHO SUW DI BQ.

A second embodiment of the invention, a personal electronic key, is described in claim 3 and shown in Fig. 2 using a specific example.

A display 2 is installed in an elongated plastic housing 1 , on which up to about 25 characters can be displayed in one line. By pressing key 3 , brief statements, in particular combinations of names, that the key owner must verify, become visible one after the other, for example by pressing the key twice. After a certain number of verifications, an electronic signal is available for a short time, which - after inserting the key into a suitable electronic lock - triggers the intended effect, via contacts 4 on both sides of the key.

The electronics essentially consist of a memory from about 500 to 1500 bytes in size and a processor for that Calling up, displaying and comparing the stored texts, as well as for recording, storage and time-dependent release of the signal. As an input device for the texts and at The need for a modified electronic signal is used by the Key separate keyboard, in the housing of the key is inserted for "loading". To trigger the Key action turns the key into a corresponding one electronic lock inserted.

The main advantages of the personal electronic key are:

First, only the key holder is after the psychometric principle able to "sharp" the key  close. He does not need any code or Remember the PIN. Nobody can copy the key.

Second: The texts used for verification and the Signal are interchangeable.

Thirdly, the greatest use of the key is expected e.g. B. as a car immobilizer, for access to rooms and Devices, at all in all cases where so far not personalized keys can be used.

Fourth: The simplest construction from existing components.

Claims (3)

1. Psychometric authenticator with associations based on individual knowledge and experience of a person, in particular in the form of written texts, characterized in that the texts as word pairs of the type AB in two vertical columns - of which the first all words A and the second contains all the words B - visibly recorded on a card or on a sheet or stored as logic or correct statements in electronic memory. 2. Psychometric authenticator according to claim 1, characterized characterized that the order of belonging together Words A and B are different within the two columns is and between the two columns of words in the amount of Words B characters within one or more also vertical columns are entered, which - in the Order of words A and those associated with them Words B put together - result in secret codes, the Columns of signs and the sequence of the words A in each Sign column are individually marked. 3. Psychometric authenticator according to claim 1, characterized by all or part of the following features:

• a) the memory with the statement texts is located in a key-like housing, the at least one display for displaying each text, at least one key for calling, verifying and deleting the texts on the display and at least one area for entering and changing the texts and for Contains input, for changing and for outputting the signal;
• b) as an input device for the texts, which are preferably half correct or wrong, and for the signal is a keyboard unit separate from the key, with which the former is brought together for loading or changing the texts and the signal;
• c) the memory is switched electronically so that after actuation of the key from the total amount of texts one after the other, individual texts become visible on the display in an unpredictable order, which can be verified as correct or incorrect and deleted from the display by the key user by pressing the key;
• d) after a certain number of correct verifications and for a limited time, the electronic circuit releases signals with which a certain effect is triggered;
• e) after a certain number of incorrect verifications or attempts to gain unauthorized access to the stored information, the electronic circuitry blocks or deletes the possibility of signal output;
• f) the key, the keyboard unit and the signal receiver (the "lock") are - as far as necessary for the function - with the usual electronic and mechanical components of psychometric authenticators such as power sources, processors, timers, actuators, contacts, protective devices against unauthorized actuation, etc . fitted.
