Method for producing a data structure for use in password identification

An identification method executed by a identification system comprising at least a matrix of characters, a personal first character, a starting point symbol and a reading path, this identification being based on the following steps:

• determining the matrix of characters used by the user,
• introducing by the user an identification code extracted from the matrix by reading of characters according to the reading path, wherein at least one character of the identification code is positioned not contiguous on the right-hand side to the previous character, the first character on the reading path being determined by the intersection of the line identified by the starting point symbol and the column identified by the personal first character,
• generating a reference identification code by the system of identification on the basis of the matrix, the personal first character, the staring point symbol and the reading path,
• comparing the identification code introduced by the user and the reference identification code,
• accepting the identification if both identification codes are similar.
