  • Patent number: 9269161
    Abstract: The present invention relates to anti-counterfeiting field, and more particularly, to an anti-counterfeiting method, device and system based on textures of an object to be tested. The method includes: providing a light source based on a pre-determined anti-counterfeiting test model, projecting light emitted by the light source on a pre-determined test area, obtaining a pre-determined number of pictures of the pre-determined test area by means of a pre-determined optical sensor, acquiring texture characteristics of the pre-determined test area from the pictures, computing similarity between the texture characteristics and pre-stored texture characteristics and outputting a test result based on the similarity. The present invention implements anti-counterfeiting function by using the texture characteristics of the object itself and improves the anti-counterfeiting level greatly without increasing complexity of the production of the object.
