The authenticity determining device 200 converts the magnetic value corresponding to the magnetic component into magnetic values and obtains the magnetic discrimination information (eg, the fifth discrimination information) corresponding to the converted magnetic value as a plurality of discrimination information.

The authenticity determination device 200 generates a code by combining some or all of the discrimination information corresponding to the plurality of non-transmitting substances and the discrimination information corresponding to the sensed substance characteristics (S660).

In step S660, the authenticity determination device 200 is visible light source discrimination information (eg, first discrimination information), infrared discrimination information (eg, second discrimination information), fluorescent light source discrimination information (eg, third discrimination information), conductivity The symbols corresponding to each of the discrimination information (eg, the fourth discrimination information) and the magnetic discrimination information (eg, the fifth discrimination information) are checked (eg, 1,2,3,4,5). The authenticity determining device 200 generates a code by combining some or all of the symbols.

The authenticity determination device 200 performs code validation on the generated code to generate code validation results (S670).

In step S670, the authenticity determination device 200 compares the order and position of symbols included in the code to check the validity of the code and the order and position of the symbols for the authenticity identification security sheet, and differs by a predetermined threshold or more. When a part occurs, a validation result that does not approve the validity of the code is generated.

The authenticity determination device 200 compares the order and location of symbols included in the code and the order and location of symbols for the authenticity identification security sheet, and compares the validity of the code when different parts occur below a predetermined threshold. Generates validation results to approve.

The authenticity determination device 200 determines the authenticity of the object to which the security sheet for authenticity determination is attached based on whether the code is a normal code or a randomly forged code based on the result of the code validation (S680).

In step S680, the authenticity determining device 200 determines whether the object to which the security sheet 100 for authenticity determination is attached or printed is genuine by confirming that the code is a normal code when the code validity test result is approved. do. The authenticity determination device 200 determines that the code is a forgery code if the code validity test result is not approved, and determines the object to which the security sheet 100 for authenticity determination is attached or printed as a forgery.
