Abstract
Provided is an uncopyable hologram QR code, According to an embodiment of the present disclosure, a 3D code generation method divides a 2D code having specific information recorded thereon into a plurality of sub 2D codes, and generatES a 3D code by coupling at least one of the divided sub 2D codes at a different depth. Accordingly, a QR code is recorded on a hologram recording medium as a hologram, and is displayed and scanned, so that it is impossible to easily duplicate the QR code unlike an existing 2D QR code.
