LABEL FOR DETREMINING AUTHENTICITY OF A PRODUCT, METHOD FOR PRODUCING AUTHENTICATION CODE OF THE LABEL, METHDO AND SYSTEM FOR DETERMINING AUTHENTICITY OF THE LABEL, MOBILE PHONE FOR DETERMINING AUTHENTICITY OF THE LABEL, AND COMPUTER READABLE MEDIUM FOR DETERMINING AUTHENTICITY OF THE LABEL

摘要

The present invention relates to a security technology for preventing reproduction of a product and, more specifically, to a label for genuine product authentication, a genuine product authentication method for the label, and a device thereof. According to the present invention, the label for genuine product authentication includes: a carrier layer which is made of transparent or semi-transparent material; and a plurality of first and second reflection particles which are arranged inside the carrier layer. Also, according to the present invention, a method of generating an authentication code for a label includes a step of comparing brightness of grid coordinate sets corresponding to two different normalized images, granting a code value for classification as a perfect reflection particle to a corresponding coordinate set if the brightness difference is within a predefined range, and granting a code value for classification as a biased reflection particle to a corresponding coordinate set if the brightness difference is greater than the predefined range. Furthermore, according to the present invention, a label authentication system includes: a label registration device for generating a registration authentication code; a label reader for generating a test authentication code; and a label authentication server. According to the present invention, a mobile wireless terminal includes: a control unit; a display unit; a camera; a wireless communication module; and a memory device for storing a label authentication application program to be run by the control unit.
