<P>PROBLEM TO BE SOLVED: To provide a pattern for securing the confidentiality of information while simplifying data processing after the information is fetched by an imaging device. <P>SOLUTION: Disclosed is an information expression method for arranging a pattern 110 with a first shape specifying the center and reference direction of an information expression pattern 101, and for arranging a pattern 130 with a second shape at each of a plurality of intersections between a plurality of virtual circles whose center is common to the center of the information expression pattern 101, and whose radiuses are different and a plurality of virtual radial rays specified by every predetermined central angle with the reference direction as a reference. A correspondence relation between the position of every predetermined digit of a numerical value as information to be expressed and the intersections of the virtual radial rays and the virtual circles is specified, and the pattern 130 with the second shape is arranged at each of the specified intersections. <P>COPYRIGHT: (C)2012,JPO&INPIT |
