One-object one-code commodity anti-counterfeiting and tracing system based on digital watermark two-dimensional code

Abstract

The invention discloses a one-object one-code commodity anti-counterfeiting and tracing system based on a digital watermark two-dimensional code. The system comprises a small commodity anti-counterfeiting and tracing system based on a digital watermark two-dimensional code and a tracing and checking WeChat program, a WeChat official account based on the digital watermark two-dimensional code and the tracing and checking WeChat program, and an application program based on the digital watermark two-dimensional code and the mobile phone tracing and checking program. Aiming at the problem that a general two-dimensional code technology cannot distinguish information authenticity and prevent counterfeiting, on the basis that a server computer generates a standard two-dimensional code, a productcode with one object one code is used as digital watermark information to be hidden in the two-dimensional code to generate an anti-counterfeiting label. Consumers purchase commodities, using a sourcetracing and checking WeChat applet or a source tracing and checking WeChat official account or a mobile phone terminal source tracing and checking application program to carry out digital watermark identification and reading on the two-dimensional code on the anti-counterfeit label. Traceability checking is carried out according to the existence of digital watermark information (product codes), the anti-counterfeiting traceability capability of the two-dimensional code is improved, and the double effects of effective counterfeiting prevention, tamper prevention and accurate tracking are achieved.

Description

technical field [0001] The invention belongs to the fields of digital watermarking, commodity anti-counterfeiting and traceability. It specifically involves embedding a digital watermark in the QR code generated by the computer system, and detecting the existence and content of the digital watermark in the QR code through traceability inspection WeChat applets or traceability inspection WeChat public accounts or mobile phone traceability inspection applications, so as to realize the authenticity of commodities. Reliable anti-counterfeiting and traceability. Background technique [0002] A two-dimensional code is a black and white geometric figure that records data symbol information and is generated by arranging several specific figures on a two-dimensional plane according to certain rules. In the writing of its code design, it uses the "0" and "1" bit stream principles that constitute the internal logic basis of the computer, and uses multiple geometric shapes correspondin...
