Abstract

The invention discloses a trusted traceability system and method based on blockchain and the Internet of Things. The system includes a mobile traceability terminal, a base station, a cloud server and a certificate system; the mobile traceability terminal installs a certificate issued by the certificate system when it leaves the factory, connects to the nearest base station during circulation, and uploads the traceability data to the base station after passing the verification of the base station; the base station passes the certificate system The terminal is authenticated with the blockchain platform. After the authentication is passed, the traceability data is received, signed and endorsed, and then the base station’s own information is added to form a complete traceability data package and uploaded to the blockchain platform; the cloud server provides the traceability business system, which can Query the complete traceability track; aiming at the risk of falsification of blockchain traceability data, the present invention guarantees the reliability of traceability data by introducing base stations for endorsement.

Description

technical field

[0001] The present invention relates to the technical fields of Internet of Things, block chain and traceability, and in particular to a trusted traceability system and method based on block chain and Internet of Things. Background technique

[0002] The traceability of commodity information has always been a hot topic of social concern. Information such as the source of food production and processing and whether vaccine transportation meets the standards can effectively protect the legitimate rights and interests of consumers. There has always been a huge gap in the credible traceability of commodities, and there is a large amount of data tampering risk in traditional traceability methods. , unable to technically guarantee the authenticity and reliability of the data. The specific performance is in the following aspects: 1. There is a risk of data tampering in the traceability of paper records, and it is difficult to retain them for a long time. 2. Using RF...

Examples

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, the present invention proposes a trusted traceability system based on blockchain and the Internet of Things. The system includes mobile traceability terminals, communication base station facilities running blockchain nodes, cloud servers, and certificate systems; base station groups and cloud servers Form a distributed blockchain platform;

[0031] When the mobile traceability terminal leaves the factory, the digital certificate issued by the certificate system is installed. When it is in circulation, it is often in the process of continuous movement of geographical location. In different geographical locations, the certificate issued by the certificate system is used to connect to the nearest base station. After passing the verification of the base station Upload traceability data to the base station;
