1. A method for recalling a specific set of characters in a geometric matrix positioned on or in a device, comprising:

  • choosing a pattern with a specific progression, which creates a sequential pattern within said geometric matrix, so that said specific set of characters will exactly fill all positions in said chosen sequential pattern;

    placing the specific set of characters within the geometric matrix, in the sequential pattern, in predetermined order;

    positioning a random set of characters in selected non-sequential pattern vacant positions within said geometric matrix, so that the sequential pattern positions of the specific set of characters in the geometric matrix and said random set of characters in said non-sequential pattern positions within the geometric matrix fill all positions within the geometric matrix; and

    Recognizing the sequential pattern within the geometric matrix, allows a determination of the specific set of characters in correct order.
