Kind Code:
A1
Abstract:
The purpose of the present invention is to make it possible for a person to easily determine whether or not an information code has been substituted. On the basis of original information (340) obtained by capturing and decoding an image of an optically readable information code (210), an information processing device (1) acquires first class information (350) indicating a class into which the object visually represented by first visual information (220) is classified, said first visual information (220) being to be displayed together with the information code (210). When second visual information (220) is displayed together with the information code (210) and, as a result, an image of the second visual information (220) is captured together with an image of the information code (210), the information processing device (1) acquires second class information (360) indicating a class into which the object visually represented by the second visual information (220) is classified. The information processing device (1) compares the first class information (350) with the second class information (360). On the basis of the result of the comparison, the information processing device (1) controls the execution of a prescribed process that uses the original information (340).
