An anti-counterfeiting method and system for identifying by using the physical characteristics of the substance itself

Abstract

The invention discloses an anti-counterfeiting method and system for identification by using the physical characteristics of the substance itself, and the substance can transmit light; the method comprises the following steps: predetermining the position for collecting the physical characteristics on the substance to be identified, and placing the substance to be identified Between the light source and the optical system and optical sensor that collects the image, obtain the physical feature image collected optically after transmission; perform image processing on the physical feature image, extract the physical feature data, and record it in the feature database or record it in the form of a two-dimensional code In terms of material: conduct pattern recognition with the physical feature data recorded and stored in the feature database or two-dimensional code, and judge whether the consistency is consistent, so as to judge the authenticity of the material. The anti-counterfeiting method and system for identifying the physical characteristics of the material itself in the present invention can achieve low-cost image acquisition of its physical characteristics through transmission on a light-transmitting material, and realize the authenticity of the material after corresponding pattern recognition. Fake anti-counterfeiting identification.

Description

technical field [0001] The invention relates to a physical anti-counterfeiting method and system for substances, in particular to a method and system for realizing anti-counterfeiting by utilizing the physical characteristics of the substances themselves. Background technique [0002] The paper anti-counterfeiting or bill anti-counterfeiting in the prior art mainly achieves the purpose of anti-counterfeiting by adding specially controlled raw materials or special paper, and through strict control of raw materials or related technologies, such as adding fluorescent fibers to paper to realize physical uniqueness of features. [0003] However, when certain physical characteristic raw materials or technical controls are used to realize paper anti-counterfeiting, such as adding fluorescent fibers, higher processing technology is required, which requires high production cost and technical level, and the systematization requirements for its realization are complex and need to be de...

Problems solved by technology

[0003] However, when certain physical characteristic raw materials or technical control are used to achieve paper anti-counterfeiting, such as adding fluorescent fibers, higher processing technology is required, which requires high production costs and technical levels, and the systematization requirements for its realization are complicated. The traditional papermaking process adds an additional process, the process is too complicated, and at the same time increases the cost of paper, such as figure 1 The dimensions of the various fibers shown are on the order of microns
