Abstract

In a digital multi-function peripheral, a QR code generation section generates image data of a QR code on the basis of first data for security of obtained image data. An encryption section encrypts second data for security of the image data. A micro gradation generation section generates a micro gradation (a gradation pattern) on the basis of the second data having been encrypted by the encryption section and history data, and adds the micro gradation to the image data of the QR code generated by the micro gradation QR code generation section.
