| Outline of Final Research Achievements |
As countermeasures against counterfeiting and imitation of metal parts, we devised a new two-dimensional code to replace anti-counterfeit labels, bar codes and QR codes. We developed and improved a recognition algorithm by utilizing template matching, and showed that it can correctly recognize the laser marked two-dimensional code when it is over 2 mm in size. Furthermore, high accurate recognition was achieved even with extremely small size of about 1 mm by utilizing etching process instead of laser marking. A field study was conducted on the current status and countermeasures of infringement of intellectual property rights in Vietnam and China, and it leads to the results that the new two-dimensional code has a practical feasibility.
