Embodiment Construction

[0022] In order to facilitate those skilled in the art to understand the technical content of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 2 Shown is the flowchart of the scheme of the present invention, specifically comprises the following steps:

[0024] A method for producing a two-dimensional code used in the tobacco industry, comprising the following steps:

[0025] S1: Two-dimensional code definition, the traceability number is encrypted through an encryption algorithm to obtain a unique two-dimensional code definition for each product, and a two-dimensional code image is generated; the traceability number is a random code with a length of N, in this embodiment where N is 17. Through the mixed encryption method of DES and RSA, the random code is encrypted to obtain the two-dimensional code image, which ensures the security of the image and is...

Abstract

The invention discloses a two-dimensional code production method for the tobacco industry. By adopting random codes as product source-tracing codes, the two-dimensional code production method adopts an encryption algorithm to obtain definitions of two-dimensional codes, and generates two-dimensional code images, a two-dimensional code is attached on each piece of product, the random codes are obtained by reading the two-dimensional code images of the products, and are matched with product information in a product database, so that unique identification codes for the products are obtained, and the laser marking method is adopted to mark a unique identification code on each piece of product; by scanning the two-dimensional codes and inputting the unique identification codes of the products, a customer can authenticate the products. The creation of a tracing system of the method disclosed by the invention not only serves as the display of the product safety and traceability of tobacco, but also solves the phenomena of logistic node management, counterfeit and shoddy products, cross-region sale and the like once and for all. By combining the two-dimensional codes with the unique identification codes of the products, the method disclosed by the invention further enhances the anti-counterfeiting intensity of the products, so that the products are hard to counterfeit.

Description

technical field [0001] The invention belongs to the field of barcode production, and in particular relates to a two-dimensional code production method. Background technique [0002] QR code (Quick Response Code), also known as two-dimensional barcode, is a black and white pattern distributed on a plane (two-dimensional direction) with specific geometric figures according to certain rules, and is a key to all information data. Such as figure 1 The QR code shown is one of the two-dimensional codes. In modern commercial activities, it can be used in a wide range of applications, such as: product anti-counterfeiting / traceability, advertising push, website links, data downloads, commodity transactions, positioning / navigation, E-commerce applications, vehicle management, information delivery, etc. Nowadays, the application of smart phone scanning (313 for short) function makes QR codes more common. With the vigorous development of the domestic Internet of Things industry, more Q...
