Abstract: An anti-counterfeit method for random textures and a recognizer thereof The method includes: A. selecting texture material 2 with texture elements 1 distributed randomly; B. a recognition system storing inherent recognition features J of texture elements 1; C. extracting random features S of distribution of texture element 1 and storing in the recognition system, texture material 2 being anti-counterfeit identification 3; D. the recognition system extracting features J? and random features S? of texture elements 1? to be recognized on anti-counterfeit identification 3?, and comparing respectively features J? with recognition features J as well as random features S? and random features S. If the compared results do not match, anti-counterfeit identification 3? is judged not to be anti-counterfeit identification 3. Otherwise, anti-counterfeit identification 3? is judged to be anti-counterfeit identification 3.

Abstract: An anti-counterfeiting fiber, anti-counterfeiting paper containing the anti-counterfeiting fiber, and manufacture method thereof. The anti-counterfeiting fiber is a slice or part of a slice cut along a cross-section of a strip-shaped fiber, wherein the strip-shaped fiber includes a specific structure along the length direction providing anti-counterfeiting characteristics. Structures manufactured using the principles of the process have better orientation than structures manufactured using conventional processes for manufacturing anti-counterfeiting fiber during the paper manufacturing process and can form more unique visual characteristics.
