<P>PROBLEM TO BE SOLVED: To provide structure related to a two-dimensional code in which a user who reads the two-dimensional code by using a reading device of general specifications cannot recognize the presence of secret data. <P>SOLUTION: In two-dimensional codes generated by code generation processing, secrete data codes are arranged after a terminal identification code instead of a portion or whole part of a filler code by a step S133. With this, since the secrete data codes arranged after the terminal identification code are not a reading target of a reading device of general specifications, even if the two-dimensional codes including such secrete data codes are read by the reading device of general specifications, the presence of data to be made secrete by the secrete data codes is not recognized. In this way, a user of the reading device of general specifications can be prevented from recognizing the presence of secret data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
