Anti-counterfeiting source tracing system based on block chain

Abstract

The invention discloses an anti-counterfeiting source tracing system based on a block chain. The system comprises the following functional modules: (1) a verification code generation module which is used for generating the unique verification code of the product; (2) a verification information storage module which stores verification information in the block chain; (3) a verification code readingmodule which reads external anti-counterfeiting information and identifies the corresponding verification code; (4) a verification code verification module which decodes and identifies the verification code; and (5) a commodity information output module which reads product information out of a database after successful matching. The unified and secure anti-counterfeiting verification mode is provided through the block chain technology and can be additive to the existing external anti-counterfeiting means so that the multistep anti-counterfeiting verification process can be simplified and the cost for anti-counterfeiting verification can be saved. New technical support is adopted so that more product information can be provided on the basis of the original anti-counterfeiting information, and the buyer of the commodity is enabled to participate in the source tracing process of the commodity and get more recognition from the commodity buying process.

Description

technical field [0001] The invention relates to the technical field of blockchain and information anti-counterfeiting traceability, in particular to a blockchain-based anti-counterfeiting traceability system. Background technique [0002] For a long time, people have been deeply aware of the counterfeit and shoddy products in the market. These "cottage" products have caused great losses to the interests of consumers, genuine manufacturers and even the interests of the country. Therefore, not only the domestic market, but even the international market Both the market and the government have joined forces to suppress these pirated products. In response to these Xibei products, various manufacturers have also proposed various anti-counterfeiting methods, which have also achieved certain results, but they have also increased the cost of brand maintenance for manufacturers and caused damage to the economy. However, the underlying technology used in the existing network authentic...

Problems solved by technology

In response to these Xibei products, various manufacturers have also proposed various anti-counterfeiting methods, which have achieved certain results, but they have also increased the cost of brand maintenance for manufacturers and caused harm to the economy. On the other hand, the pirated version market has no signs of shrinking.

However, the underlying technology used in the existing network authentication system is relatively complex, and the price paid for maintaining its data security is higher; Participate in the maintenance of product information, and the production of goods often involves multiple manufacturers, resulting in inconsistent product information standards, and it is difficult to unilaterally consider the source of products in depth
