Embodiment Construction

[0034] The invention relates to a product two-dimensional code generation and query system. The design principle should be that the commodity authentication code is permanently valid and cannot be forged. The system mainly includes: a product information storage platform, a two-dimensional code generator for manufacturers, and a query client for customers. The product information storage platform is a database for storing product information. The manufacturer's QR code generator is a QR code generator that can generate specified functions. The QR code generated by it can be recognized by ordinary mobile scanners with some useful information, such as production date, product merchant, shelf life, etc. Consumers The information concerned can also be combined with the query client to query some hidden information through the authentication code, that is, the unique identity code that cannot be forged. The customer's query client is a platform for consumers to query the authentic...

Abstract

The invention discloses a product two-dimension code generation and query system. The product two-dimension code generation and query system comprises a product information storage platform, a two-dimension code generator of manufacturers, and a query client side of clients, wherein the product information storage platform is connected with the two-dimension code generator of manufacturers and is used for storing original information of products and authenticity information of products, the two-dimension code generator of manufacturers encrypts the authenticity information of products and then mixes the authenticity information of products with the original information of products to generate two-dimension codes of products, and the query client side of clients is connected with the product information storage platform and is used for querying the original information and the authenticity information of products. The product two-dimension code generation and query system can be used for recognizing authenticity of commodities, can also carry out normal recognition, obtains useful information of commodities, can effectively guarantee uniqueness of article numbers of commodities, and prevents lawless persons from obtaining and forging two-dimension code labels of commodities through some unjustifiable means.

Description

technical field [0001] The invention relates to product anti-counterfeiting, information retrieval and encryption technology, in particular to a product two-dimensional code generation and query system. Background technique [0002] In today's society, regarding product ID codes, the development of logistics codes has been quite mature, and the most commonly used ones are bar codes and QR codes. They are mainly used to store information, identify information, etc. However, regardless of the barcode or QR code, you can use some mobile devices in your daily life, such as mobile phones, to identify the information contained in the barcode and QR code, including price, authenticity, attributes, etc., which is very convenient and practical, and Easy to operate. [0003] Up to now, the technology of identity authentication code has been relatively perfect, and can roughly meet the needs of consumers. However, it still has defects, that is, it cannot resist some illegal merchants...
