ABSTRACT:
The configuration procedure for an access code and for a security code is provided, comprising: providing references retaining element file that records the base checkerboard-like substrate, checkerboard-like substrates and the color substrates as a graphical image with a hierarchical layered structure arranged on the base substrate, assigning the digital elements to both the x- and the y-axes of the base substrate, assigning the digital elements assigned to the references retaining element on the base substrate perpendicular to the selected two retaining element to the selected two retaining element of the checkerboard-like substrate, configuring code based on the assigned digital elements and the prescribed priority order of the first and areal codes and at the time of the code configuration, recording the location of the retaining element, coaxially rotating the checkerboard-like substrates and color substrates with respect to base checkerboard-like substrate, whereby a new code is configured based on the assigned digital element of the retaining element and the prescribed priority order of the first and second areal codes, and in data accessing, performing code inputting after returning each position of the retaining elements to their initial locations based on the record of each of the retaining elements' relationship of the positions.
