Embodiment 1

[0031] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the laser marking multiple encrypted two-dimensional code fingerprint anti-counterfeiting authentication method of the present invention includes a step of encoding the original information into a two-dimensional code and an authentication step, wherein, in the encoding of the original information into a two-dimensional code in the steps, such as figure 1 As shown, the original information is encrypted first, and then the encrypted information is encrypted twice or more to obtain multiple encrypted QR codes. figure 1 LELEE328101 in can represent the information disclosed by the product, and can also be used as the key management number. After the step of encoding the original information into a two-dimensional code is completed, use a laser marking device 1 to etch the multiple encrypted two-dimensional code on the surface of the article 2, and at the same time, use the two-dimensional code...

Abstract

The invention relates to a laser marking multi-encrypted two-dimensional code fingerprint anti-counterfeit authentication method, comprising the following steps of: coding original information into a multi-encrypted two-dimensional code, etching the multi-encrypted two-dimensional code on the surface of an article by utilizing a laser marking device, and storing a multi-encrypted two-dimensional code image etched by laser and a secret key into a two-dimensional code fingerprint database; and authenticating, namely acquiring the multi-encrypted two-dimensional code image on the surface of the article by utilizing a CCD (charge coupled device) device, then transmitting the image to a center server, processing the multi-encrypted two-dimensional code image by the center server, calling the original multi-encrypted two-dimensional code fingerprint in the two-dimensional code fingerprint database for comparative analysis and true and false judgement, and then returning a judgement result to a user. In the invention, a laser marking system, two-dimensional code terminal reading equipment, an encrypted two-dimensional code generating and management method and an encrypted two-dimensionalcode fingerprint database are adopted to form an anti-counterfeit authentication system, the requirements on processing materials and surface quality are low, and the safety is high.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to two-dimensional code encryption technology and laser technology, in particular to a laser marking multiple encrypted two-dimensional code fingerprint anti-counterfeit authentication method and system. Background technique: [0002] In the prior art, two-dimensional code technology is widely used in the fields of commodity production, circulation and warehousing, medical and health care, library information, postal services, railways, transportation, production automation management, and the like. The application of two-dimensional code technology improves the speed of data collection and information processing, improves the working and living environment, and improves work efficiency. At present, two-dimensional codes mainly include stacked two-dimensional barcodes and matrix two-dimensional barcodes. Representative stacked two-dimensional barcodes are: Code16K, Code49, PDF417, etc. Repre...
