The present invention relates to a method for discerning false from genuine. The method increases the difficulty of imitation by means of using the intrinsic stochastic structural vein of the material itself as identification. According to the method, it is advisable to select the material with clear stochastic structural vein as marker, and to select the stochastic structural vein of the marker as identification information, the information is recorded by scanner and then is stored into the database of the computer identification system. Consumers may obtain relevant information of structural vein by telephone, fax or computer on line to testify whether a product is genuine or a counterfeit.
