摘要： An anti-counterfeit fiber and an anti-counterfeit paper containing the same are provided. The anti-counterfeit fiber includes at least a first material part and a second material part that both run parallel along said anti-counterfeit fiber length direction without being twisted. The first material part contains luminescent material A and the second material part contains luminescent material B, of which both have obvious different luminescent colors visually with each other if they are under exciting light. It is characterized by that when said anti-counterfeit fiber falls freely onto a horizontal plane, one of surfaces of the two material parts is upward, and the other is downward. The thermal shrinkage rates of these two material parts are the same in order to ensure that the surface of the first material part can orient towards one surface of the anti-counterfeit paper and the surface of the second material part can orient towards the other surface of the anti-counterfeit paper after the anti-counterfeit fiber is added to paper pulps to produce the anti-counterfeit paper. Therefore, when the two surfaces of anti-counterfeit paper are irradiated by exciting light respectively, the luminescent colors of the anti-counterfeit fiber will change apparently.

摘要： Disclosed are an anti-counterfeiting fiber (1), anti-counterfeiting paper containing the anti-counterfeiting fiber, and manufacture method thereof. The anti-counterfeiting fiber is a slice (4) or part of a slice cut along a cross-section (3) of a strip-shaped fiber (2), wherein the strip-shaped fiber comprises a specific structure along the length direction providing anti-counterfeiting characteristics. Structures manufactured using the principles of the process has better orientation than structures manufactured using the original process for manufacturing anti-counterfeiting fiber during the paper manufacturing process and can form more unique visual characteristics.

摘要： An anti-counterfeit method for random textures and a recognizer thereof are provided by the invention. The method includes the following steps: A. texture material 2 with texture elements I distributed randomly is selected; B. a recognition system stores inherent recognition features J of texture elements 1; C. random features S of distribution of texture element 1 are extracted and stored in the recognition system, and texture material 2 is enabled to be anti-counterfeit identification 3; D. in recognizing, the recognition system extracts features J' and random features S' of texture elements 1' to be recognized on anti-counterfeit identification 3' to be recognized, and compares respectively features J' with recognition features J as well as random features S' and random features S, if one or two of the compared results does not match, anti-counterfeit identification 3' to be recognized is judged not to be anti-counterfeit identification 3, otherwise, anti-counterfeit identification 3' to be recognized is judged to be anti-counterfeit identification 3. The method can be applied to implement that the inherent features of a texture element are not imitated and deceived by printed texture elements, and it can support a cheep and simple recognizer.
