Proposal of Flicker-Based QR Code with Invisible Information Display Lighting Device

Abstract

This paper proposes a special QR code by using a LED-based display Stego-panelV. This QR code is invisible to the human eyes. On the otherhand, this can be recognized by a camera equipped with a CMOS image sensor. However, at this time, shutter speed of the camera must be adjusted appropriately. Therefore, by using this system, it is possible to improve the security by making it difficult to duplicate the QR code and secretly photograph it. To achieve this, we develop Stego-panelV, which has a special LED control mechanism and is operated by dedicated software, and conducted an experiment to evaluate the effectiveness of the OR code.
