How is the QR code anti-counterfeit label encrypted?

by:LG Printing     2021-04-23
With the development of technology, two-dimensional code anti-counterfeiting labels have quietly appeared in our field of vision, and most of the products in the mall have traces of it. The two-dimensional code anti-counterfeiting label has the characteristics of easy identification and a large amount of stored information, which effectively combats counterfeit and shoddy goods. The encrypted information of the QR code is the key, so how is the QR code encrypted?



   The difference between general two-dimensional anti-counterfeiting technology and encrypted two-dimensional anti-counterfeiting label technology can explain two points. One is to analyze the basic principles of two-dimensional anti-counterfeiting technology and encrypted two-dimensional code anti-counterfeiting technology from their technical characteristics.



  The anti-counterfeiting label is small, but it has a great ability. It can play an anti-counterfeiting effect, and can make the product packaging look more delicate, so that we can shop more at ease. The production requirements of QR code anti-counterfeiting labels go through the following stages.



  Design: After the manufacturer determines the anti-counterfeiting of the product, the designer customizes the anti-counterfeiting label according to the manufacturer's requirements, including style, material, anti-counterfeiting technology, technology, etc.



   Final draft: It is impossible to make a complex anti-counterfeiting label at will. It requires designers to consider repeatedly according to the beauty and actual situation, after all, to determine its model.



   The following is a series of processes in the factory, such as film production, printing, quality inspection, inspection, and shipment.



   The dynamic two-dimensional anti-counterfeiting company code generated by the two-dimensional anti-counterfeiting code uses the two-dimensional code as a promotional carrier to load the company’s development story and product information. By scanning the two-dimensional code, you can directly go to the company’s mobile website and enter the mobile Internet. import. WeChat anti-counterfeiting adopts WeChat, a new communication method uploading anti-counterfeiting verification requires consumers to go to the back-end database, and then send back the compared verification results, and then allow consumers to obtain the product's true and false information.



   The basic principle difference between general two-dimensional code anti-counterfeiting technology and encrypted two-dimensional code anti-counterfeiting technology:



  The general two-dimensional code only needs to use the device's smart phone with any two-dimensional scanning code software, and you can browse and query the content of the two-dimensional code production. The content can be text, pictures, URL links, and everything that can be customized. The works are different. The secret QR code requires the designated scanning software device's phone, which can scan the QR code for production information query, and the content customization can be different for each piece. This type of software is a QR code developed independently. Software, consumers are using non-designated software to scan to obtain blank pages or codes.



  The principle difference between general two-dimensional code anti-counterfeiting technology and encrypted two-dimensional code anti-counterfeiting technology:



   General two-dimensional code anti-counterfeiting technology: general two-dimensional code, also known as two-dimensional bar code, is to use specific geometric figures to spread on a plane according to certain rules, black and white graphics to record data symbol information; general two-dimensional code Production as a new automatic identification and information carrier technology, with its input speed, high reliability, large amount of information collection, sensitive and useful, and low system cost advantages. The general two-dimensional code is used as a record of information, and as a new generation of bar code technology, it has opened up a rich and diverse information supply shortcut.



   QR code anti-counterfeiting technology: Encrypted QR code uses the combination of world advanced mathematics, combining mathematics and cryptography, and treats all digital information (such as numbers, fingerprints, palmprints, photos, iris, etc.) as the original The data encryption algorithm generates a set of encrypted data files (ie, two-dimensional barcode encryption). The key to encryption is in the hands of the user. The user uses the key to decrypt and read the encrypted data file (encrypted two-dimensional bar code), and convert it into a data pattern, which is compared with the original data to distinguish the authenticity. At the same time, the encrypted information capacity of the key is as high as 128 bits, which is almost impossible to decipher. At the same time, data encryption technology is combined with existing material anti-counterfeiting technology to make the application of encrypted QR code production technology in documents more stable.
