Whole industry chain product traceability authentication method and system based on block chain technology

Abstract

The invention discloses a whole industrial chain product traceability authentication method and system based on a block chain technology, which support all legal nodes on an industrial chain to carry out traceability and authentication on a product at any time, and can also provide a simple and easy-to-operate authentication service for an individual user without corollary equipment and resources. Meanwhile, decentralized credible traceability is realized through a block chain technology, that is, authentication does not need to depend on the reliability of a certain node, and an authentication result can be directly and automatically deduced from information disclosed in a block chain. The method can resist more than ten attack forms including external attacks, collusion attacks and internal attacks, and has high security.

Description

technical field [0001] The invention belongs to the technical field of smart industry, and specifically relates to a method and system for product traceability and certification of the whole industrial chain based on block chain technology. Background technique [0002] In the development of smart industry and smart city, upstream and downstream manufacturers and consumers have more and more urgent needs for the whole process traceability of goods. Traceability of goods can not only improve the shopping experience of consumers, reduce the cost of enterprise certification, but also promote the healthy development of the market. In this regard, this patent aims to use the combination of passive radio frequency technology (RFID) and blockchain technology to achieve safe and reliable product traceability. With the widespread deployment of radio frequency identification in many applications such as retail, warehousing, and logistics, passive radio frequency technology (RFID) tec...

Problems solved by technology

[0007] First, anti-counterfeiting labels often help consumers to authenticate by counting. If authentication is carried out in all links of product transshipment and distribution, the number of authentications can no longer be used as an authentication indicator;

[0008] Second, even if all links in the middle can be authenticated, the centralized authentication method will greatly increase the burden on the manufacturer's server, and the number of visits will increase exponentially

[0009] Third, such passive anti-counterfeiting labels often have short communication distances and are not suitable for practical environments such as warehousing and logistics. For example, the communication distance of NFC nodes is only 10cm, which cannot meet the daily reading and circulation needs of bulk goods. The communication distance is as high as 10 meters to 12 meters, and the price is almost one-fifth of the NFC node
