Anti-fake structure of optical readable bar code and realization method of anti-fake structure

Abstract

The invention proposes an optically readable barcode anti-counterfeiting structure and a realization method. The structure is composed of a barcode part and a light-changing area. The light-changing area is set at least one area around the barcode logo, and the light-changing area is a laser holographic film made by optical diffraction, or a light-changing film made by optical interference, or a light-changing film printed by OVI light-changing ink made by optical interference. Light images, or thin films formed by arrays of microlenses. As the reading angle changes, the combination of the light-changing area and the printed image of the logo will form various images that cannot be reproduced by ordinary scanners. At the same time, the optical readability dot matrix code can also be embedded All kinds of anti-counterfeiting and traceability information will not affect the printing quality of the image. Through three kinds of anti-counterfeiting technologies, the anti-counterfeiting, anti-copying, commodity traceability and other functions of public mobile phone reading can be realized. The method can solve the problem that all signs that can be read by mobile phones in the world can be copied, and has the characteristics of being simple, practical and easy to popularize.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to an optically readable barcode anti-counterfeit structure and a method for realizing the optically readable barcode anti-counterfeit structure. Background technique [0002] In recent years, food safety issues have attracted more and more attention from the society and the government, and the phenomenon of counterfeit goods has not been effectively curbed. [0003] The social problem of eradicating counterfeit goods depends on the public to solve. For this reason, technology that supports the public to read authenticity has attracted much attention today. [0004] The traditional method of using the mark formed by the diffraction of light to realize the authenticity identification of the public has been widely used. Until 2012, American researchers also disclosed the "multi-viewpoint image recording medium and authenticity determination method" (Patent Document 1) in Japan. ...

AI Technical Summary

Problems solved by technology

As the vast majority of mobile phones have not imported MFC chips, the identification of RFID code content cannot be realized through mobile phones, so that it is difficult for mass mobile phones to identify the authenticity of goods, and the high cost of RFID has always hindered the popularization of this technology.
