Benefits of technology

[0005] It is therefore an object of the invention to provide a method for creating a data structure that can be used, e.g. in the form of a readable representation or stored on a disk, in order to create passwords requiring considerably reduced memorizing efforts of the user.

Problems solved by technology

Without knowledge of the principle, this would require high processing power and time.

example of application

[0085] An exemplary application will be given for the access to an IT workstation (computer). Each user receives a matrix in paper format or on a diskette on which an encoded matrix 27 is stored. Each user must be identified by the system the first time. For this purpose, the user must insert the diskette in the computer with the password creation system installed and create his or her password, i.e. a code (e.g. two letters), a “starting point symbol” and a “reading path” (that can be inscribed in a grid on the screen). Using the method described above, the system stores the created password parameters and transmits it to the identification system.

[0086] In case that the matrix is printed, an additional unique number is printed to the support which allows the identification system to retrieve the matrix used by the current user.

[0087] An IT application is running on the personal computer of the user. In order to be identified, the user must identify the matrix used, e.g. diskette...

Abstract

Passwords consisting of symbols selected from a third set of third symbols, of which a first set constitutes a subset of the first symbols, can be created from a data structure. The method for obtaining this structure comprises the following steps: preparation of a second set of at least two second symbols; creation of a first number of first lists of the first symbols, each list being contained in a third list constituted of the third symbols; creation of a second list of the second symbols, each symbol appearing in that list only once; association of a first list with each symbol of the second list; association of a second symbol to each symbol of the first lists. With this structure, a multitude of pseudo-random passwords can be created by means of a code comprising a second symbol, a subcode of at least one first symbol, and a reading path of the symbols in the third lists of the structure, starting from a first symbol found by using the second symbol and the subcode.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 181,330, filed Jul. 15, 2002 entitled METHOD FOR PRODUCING A DATA STRUCTURE FOR USE IN PASSWORD IDENTIFICATION which is a U.S. National Stage of application No. PCT / CH01 / 00031 filed on Jan. 16, 2001, which claims the benefit and priority of Switzerland Application No. 2000 0080 / 00, filed in Switzerland on Jan. 17, 2000, the contents of which are incorporated by this reference.FIELD OF THE INVENTION [0002] The present invention relates to a method to identify a user willing to access services through a network by entering a password. The present invention refers to a method and device to allow strong identification of the user. BACKGROUND ART [0003] Every user of information technology has already been confronted with the problem of choosing an access password. The difficulty is to remember the password. This is why most people use words that are easy to re...
