A random-type multilayer identifier uses an identification pattern that is formed by irregularly-dispersed identification particles as unique information and is configured in such a manner that two or more identification layers made out of a transparent material are stacked each other, and besides, has an advantage that significantly reduces the duplication possibility of an existing identifier provided in a printed manner, such as a QR code, a barcode, a hologram, etc., because multiple identification layers having the irregularly-dispersed identification particles are stacked each other and recognized as two-dimensional data. |
