Three-dimensional code seal anti-counterfeiting method and system based on image cloud recognition technology

Abstract

The invention discloses a three-dimensional code seal anti-counterfeiting system based on an image cloud recognition technology, which comprises a use end, an image recognition module, a three-dimensional code seal generation module and an anti-counterfeiting recognition image comparison module, and is characterized in that the use end is connected with the image recognition module, the three-dimensional code seal generation module and the anti-counterfeiting recognition image comparison module; and the image recognition module is connected with the anti-counterfeiting recognition image comparison module. The temporary reset code for image recognition is generated in the preset space through the encryption security code according to the error-tolerant rate information, and then the space where the random encryption security code is located is filled with the temporary reset code, so that the image recognition security code is generated, corresponding identification of a product and a bar code does not need to be carried out through physical anti-counterfeiting, and the security code identification efficiency is improved. According to the anti-counterfeiting method, the condition that images and bar codes adopted by physical anti-counterfeiting are copied to be counterfeited is avoided, the authenticity distinguishing efficiency is guaranteed, verification and use can be carried out under the condition that damage is not generated, and the flexibility in application is improved.

Description

technical field [0001] The invention relates to the technical field of bar code anti-counterfeiting, in particular to a three-dimensional code seal anti-counterfeiting method and system based on image cloud recognition technology. Background technique [0002] The 3D code has a larger information capacity, the same ease of identification and better security. How does the 3D code achieve a large amount of information: whether it is a one-dimensional barcode or a two-dimensional code, it is printed on a plane, and it is a two-dimensional code. The coding of dimensional space. These codes use bars and spaces of a certain length and width to represent data, and four bars and four spaces represent 1 byte. Another feature of 3D codes is that they have a large amount of information, and on the same coding area , the maximum amount of data that can be represented is more than 10 times that of PDF417 code, so it can contain a large amount of auxiliary information enough to identify a...

Problems solved by technology

[0003] At present, the existing anti-counterfeiting methods through image recognition and barcodes on the market are mainly through physical anti-counterfeiting methods, that is, through commodity packaging, anti-counterfeiting labels and jet printing processes to carry out the corresponding identification of products and barcodes. It can be copied, so it is still easy to be forged, which increases the difficulty of distinguishing the authenticity, and those methods that need to open and break the outer packaging can only be verified and used once, and the application is very inflexible
