| Abstract(in English) | The Quick Response (QR) code is used for various purposes, such as accessing web pages, payment, etc. The QR codes which are storing multiple messages will lead to the development of new services. We have already proposed a fake QR code that probabilistically outputs two messages using the feature of the error-correcting code. This paper focuses on image processing on QR code decoders and proposes the hologram QR code that can control the output message depending on the scanning angle. We experimented with the hologram QR code with multiple smartphones and decoders and confirmed that it is possible to get two messages by tilting a smartphone to the left and right and scanning the QR code. |
