Anti-counterfeiting method and system for combined use of plain and secret codes

Abstract

The invention relates to an anti-counterfeiting method and system for combined use of plain and secret codes, and the method comprises the steps: an anti-counterfeiting system provides a plain and secret code group for each product, the plain and secret code group is a combination of plain codes and secret codes formed in a mode of N plain codes + M secret codes (wherein N is greater than or equal to 0 and M is greater than or equal to 1), and the secret codes adopt a network variable ID mode, one group of secret codes corresponds to one group of webpage IDs; after a user opens one secret code in sequence or randomly and scans the code for access, the anti-counterfeiting system judges whether the access is the first access or not, if the access is the first access, the product can be presumed to be a certified product, and if the access is not the first access, the product can be presumed to be a non-certified product. According to the invention, the problems that the anti-counterfeiting code is easy to collect and copy on a large scale, related core data is easy to illegally obtain, the anti-counterfeiting query of a non-purchaser puzzles the authenticity identification of a final purchaser, the anti-counterfeiting code is easy to be decoded in an exhaustive manner, and a dealer and a second-hand bearer cannot verify the authenticity are solved.

Description

technical field [0001] The invention relates to anti-counterfeiting technology, in particular to an anti-counterfeiting method and system using a combination of clear and dark codes. Background technique [0002] In the prior art, the two-dimensional code is a commonly used anti-counterfeiting traceability technology. Two-dimensional code anti-counterfeiting traceability technology refers to the use of two-dimensional code technology and wireless communication network technology, using two-dimensional code as the information carrier, to track, collect, and manage the information of each commodity, so as to realize one code for one product, so as to establish a commodity Information management data chain and the entire circulation process supervision system. In the process of use, you only need to easily scan the code through the reading software installed in the mobile terminal, and you can conveniently query the product information in real time and effectively identify...

AI Technical Summary

Problems solved by technology

[0007] 1) The plain code of the QR code is easy to be collected and copied on a large scale, and is used on counterfeit and shoddy products to confuse the public and mislead consumers

[0008] 2) The clear code information of the QR code is easily read by various QR code collection devices, resulting in the core data of related products being easily obtained illegally by other personnel, thereby reducing the security of anti-counterfeiting

If unscrupulous merchants further build fake webpages for false anti-counterfeiting certification, consumers will not be able to recognize

[0009] 3) Before the final buyer conducts an anti-counterfeiting query, the QR code may have been checked by a non-purchaser, resulting in the web page showing that it is not the first query, which brings trouble to the authenticity of the product

[0010] 4) After a large number of QR codes are collected, they are easily deciphered exhaustively

[0011] 5) The secret code can only help the end user to identify the authenticity of the product, and the dealer and second-hand dealer make it impossible for the user to confirm the authenticity of the product

[0012] 6) The database of the anti-counterfeiting system may be attacked. After the data is tampered with, counterfeit and shoddy products can also be certified by the anti-counterfeiting system

[0013] 7) Blockchain-based two-dimensional code anti-counterfeiting technology and multi-dimensional code technology have problems such as high technical threshold or high cost of use
