Anti-fake retrospect method based on multiple spectral wavelengths

Abstract

The invention relates to an anti-fake retrospect method based on multiple spectral wavelengths. According to the method, fingerprints which are randomly printed with different kinds of absorption spectrum ink are adopted, radio frequency tag codes for variable data read-write are set, the fingerprints and radio frequency tags are associated, and a server or a cloud computing platform is adopted to perform encryption and used for associating the fingerprints and the radio frequency tags; during implementation, the fingerprints are produced on object surfaces, and the server or the cloud platform generates the radio frequency tag codes; all retrospect points read the radio frequency tag plain codes through monitoring equipment, and object positions and timestamps are modified and reported; and a terminal user reads the radio frequency tag plain codes through reading equipment and obtains a fingerprint spot-check position sequence after reporting to the server or the cloud platform to check authenticity. In this way, the fingerprints and the radio frequency tags are associated in use, and therefore variable information can be conveniently read and written while it is difficult to counterfeit the codes. Due to the complexity of the fingerprints, it is difficult to achieve the purpose of goods stringing by damaging packages, and implementation security is improved.

Description

technical field [0001] The invention relates to an anti-counterfeit traceability method, in particular to an anti-counterfeit traceability method based on multi-spectrum wavelengths. Background technique [0002] As far as the existing technological development is concerned, the global industry has strengthened the requirements for product anti-counterfeiting and traceability driven by the vigorous wave of Industry 4.0 and Internet of Things demands. The new idea is to track the flow of products in real time by giving each product a permanent number, which is the so-called one code per item. [0003] With the decline of variable digital printing costs, especially the rapid popularization of inkjet coding technology, more and more industries around the world are using inkjet printing technology to realize one code for one object. At the same time, radio frequency tags are another widely used one-thing-one-code implementation solution. It can conveniently and flexibly modify...
