Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we propose a digital signature type QR code (DSQR code) that incorporates an elliptic curve digital signature algorithm into a QR code. The DSQR code makes it possible to determine the authenticity of the DSQR code itself offline without using an authentication server. In addition, we propose a modified digital signature algorithm that enables personal authentication. In the proposed algorithm, it is difficult to decrypt the password because the password is embedded in the signature value with exclusive OR. By incorporating this proposed algorithm into the DSQR code, individual identification can be performed together with authenticity judgment of the DSQR code. We incorporated the proposed method into actual machine and confirmed its effectiveness.
