PROBLEM TO BE SOLVED: To provide an illegality detection system capable of detecting illegality related to an information code.SOLUTION: When an information code, coded so that detection information is included, is imaged by a portable terminal 20, information on the detection information acquired at the time of decoding is transmitted to an illegality detection device 30. Then, a result of collation between detection information obtained from information on received detection information and collation information stored in a database 32a is transmitted to the portable terminal 20 from the illegality detection device 30 as a collation result. Then, when it is determined by the portable terminal 20 whether or not illegality on the information code exists on the basis of the collation result received from the illegality detection device 30, a determination result is notified to a user by means of display by a display part 25. |
