This research is to find out whether a photo is copied or not by using the reflective characteristics of different papers. There have been numerous studies to check whether it is a photocopy or. However, the preceding research did not consider the changes according to the lighting reflection of different papers. Accordingly, in this research, I took a photograph after choosing glossy, semimat, and dull papers when shooting photocopies with the lighting position of 0 to 90 degrees angle. In addition, I experimented by making charts that can represent the domain of black, grey, and white colors. After this, I calculated the reflection rate of different papers and applied it to photographs.
