Product code spraying anti-counterfeiting method and system based on code spraying machine

Abstract

According to a product code spraying anti-counterfeiting method and system based on a code spraying machine, the code spraying machine generates and prints anti-counterfeiting basic data A0 on the surface of a product, a code spraying machine manufacturer configures first anti-counterfeiting information A1 for the code spraying machine of a purchaser, and the purchaser configures second anti-counterfeiting information A2 for the purchased code spraying machine. Hash values H of A0, A1 and A2 are acquired by adopting a hash algorithm, and the hash values H are taken as anti-counterfeiting information; The anti-counterfeiting basic data A0 and the anti-counterfeiting information H are printed on the surface of the product. A hash value H1 is acquired by adopting a hash algorithm according tothe actually marked anti-counterfeiting basic data A0 on the surface of the product and pre-configured A1 and A2, and the hash value H is compared with the hash value H1 to judge the authenticity ofthe product. According to the technical scheme, cost is low, code spraying only needs to be carried out on the surface of a product, external equipment is not needed, database storage is not needed, an additional anti-counterfeiting marker does not need to be added to the surface of a jet printing medium, and the invention is suitable for the production environment of large-batch products.

Description

technical field [0001] The invention belongs to the technical field of inkjet anti-counterfeiting, and in particular relates to a product inkjet anti-counterfeiting method and system based on an inkjet printer. Background technique [0002] At present, products that sell well in the market are easily counterfeited by bad merchants, so many manufacturers are willing to take some anti-counterfeiting measures, but the existing anti-counterfeiting measures are either expensive or complicated to operate, which makes many manufacturers discouraged. But from another point of view, most of the current products will involve coding marks when they are produced. For example, the food industry needs to print the production date on the surface of the packaging, the pipe industry needs to print the batch number on the surface of the pipe, and the pharmaceutical industry prints the electronic supervision code, etc. . Of course, some industries are suitable for inkjet printers, and some in...

Problems solved by technology

This solution may lead to increased production costs in large-scale production, such as some small-package food industries, with large quantities and high costs

And this kind of scheme has a fatal flaw - it is difficult to prevent house thieves, because the algorithm or anti-counterfeiting features made by the original manufacturer of such a scheme may leak internally. Once leaked, the entire anti-counterfeiting system will completely fail

[0004] CN106096971A discloses an ink edge anti-counterfeiting method and an ink edge anti-counterfeiting network identification system, which implements anti-counterfeiting by making the zigzag shape of the ink. This scheme also has obvious disadvantages. One is that external equipment is required to manufacture the zigzags, and there are also requirements for the size of the zigzags. If the size is too small, the purpose of anti-counterfeiting cannot be achieved, and if the size is too large, the outline will be blurred and the display effect will be affected, and some industries do not use inkjet printing or printing, such as the laser printing industry, which leads to this scheme. It cannot be used, and all the above-mentioned schemes require a database to access these pictures or anti-counterfeiting information. With the increase of product output, the database will become larger and larger, which will also lead to an increase in storage costs, so these shortcomings lead to the application of these inventions heavily restricted
