Title CODE EVALUATION DEVICE, CODE EVALUATION SYSTEM, AND CODE EVALUATION METHOD AND PROGRAM
Abstract A 2D-code generation device (100) generates a 2D code in which an electronic watermark is embedded. A 2D-code display device (202) displays a 2D code generated in the 2D-code generation device (100). A 2D-code reproduction device (203) displays a reproduced reproduction code by imaging the 2D code displayed on the 2D-code display device (202). A 2D-code imaging device (205) images the reproduced 2D code displayed on the 2D-code reproduction device (203). The 2D-code generation device (100) evaluates the generated 2D code on the basis of the reproduced 2D code that was imaged.
