Embodiment Construction
[0034] Preferred embodiments of the present invention are described in detail below.
[0035] The present invention utilizes the anti-counterfeiting method and system of physical feature identification, and its purpose is to use the uniqueness of the physical features of the obtained material to uniquely identify the authenticity by collecting images through multiple reflections of the optical system. This technology is low in cost and easy to implement. Realized, and the image effect is easier to recognize and process.
[0036] The method and system of the present invention utilize the physical characteristics of the substance itself, such as its texture, density, height and / or color, etc., without additional anti-counterfeiting materials, and after identifying its physical characteristic image, carry out digital processing to form physical characteristic data, so as to realize anti-counterfeiting function of the label. The implementation of this anti-counterfeiting method c...
