Product authentication system and product authentication method

Abstract

The invention relates to a product authentication system and a product authentication method. The invention discloses a product authentication method. The method comprises the following steps: establishing a unique raw material identifier for each raw material for manufacturing a product, wherein the raw material identifier comprises material information of a corresponding raw material, and the established raw material identifier is stored in a database of an authentication computer system in a tree data structure based on a cutting sequence, so that the raw material from which the corresponding raw material comes can be determined based on a batch chain through the unique raw material identifier; after the requirements of the to-be-processed products are determined, randomly generating unique authentication numbers for each to-be-processed product; selecting a raw material for each product according to the requirements of the to-be-processed product, and establishing one-to-one mapping between the unique authentication number of the product and the raw material identifier of the selected raw material; after each product is processed, adding a label on each product, the label comprising a unique authentication number of the product or a code representation thereof, and a user of the product being capable of remotely querying raw material information of a raw material used by the product by using the unique authentication number of the product or the code representation thereof.

Description

technical field [0001] The invention relates to product certification, especially product certification of steel products. Background technique [0002] In the commercial market, the buyer usually has specified requirements for the materials used in the seller's product. In addition to having an important connection with the quality of the buyer's final product, this also has a significant impact on the price the buyer should pay. [0003] Taking the mold steel industry as an example, the final performance of the molds purchased by end users (such as mold users) has a major relationship with the selection of mold steel types and processing quality. End users often require sellers (intermediate suppliers, such as mold manufacturers) to use Material (or semi-finished formwork) from a designated formwork supplier of a premium brand in the industry. Because in this supply chain, the contract relationship is only between the end user and the intermediate supplier, that is, the ...

AI Technical Summary

Problems solved by technology

In addition, due to the long cycle of mold steel inventory, the date of manufacture on the original factory certificate is relatively low for end users.

[0005] Therefore, for end users, from the copy of the original factory certificate itself, it can only know that the steel mill has produced a certain piece of raw material, but it cannot know whether the intermediate supplier has ever purchased the relevant raw material, whether the intermediate supplier has ever made an order for the end user Purchasing from the formwork supplier according to the requirements, whether the required materials are provided correctly

Therefore, it is impossible to accurately trace which raw materials the products purchased come from, and there is no systematic guarantee
