Embodiment Construction

[0048] A traceability system based on the combination of blockchain and Internet of Things, including the following modules: data acquisition module, encryption module, data transmission module, SAAS module and DAPP module;

[0049] The data acquisition module is used to obtain the traceability data, photos and videos of the initial state of raw materials, growth stage, harvest stage and processing stage. The data acquisition module includes data entry equipment and image acquisition equipment. The data entry equipment uses solidity control to obtain initial traceability data through DAPP, and the image acquisition equipment uses solidity control to randomly select time points at intervals to obtain photos of raw materials and growth status data. The transparency and authenticity of the raw material production process are guaranteed. The data entry device uses solidity control to obtain initial traceability data through DAPP, and its parameters include one or more of the follo...

Abstract

The invention discloses a traceability system and method based on combination of a block chain and the Internet of Things. The system comprises a data acquisition module; an encryption module; a datatransmission module and an SAAS module, and the method comprises the steps that a production base produces the raw materials, and the initial states, growth stages, harvesting stages and processing stages of the raw materials and the traceability data, photos and videos of the finished products are collected through the data collection module; the solidity control is adopted, after the encryptionmodule is used for encryption, the HASH values of the photos and videos and the storage addresses of the photos and the videos on an SAAS module are submitted to the block chain, and the traceabilitydata is signed through a private key and is submitted to the block chain after being attached to a GAS; and a user inputs a keyword search in the DAPP module to obtain the commodity traceability, photos and videos. According to the invention, the Internet of Things technology and the block chain technology are combined, and each node on the Internet of Things is upgraded to be a block chain node.

Description

technical field [0001] The present invention relates to the technical field of commodity traceability system of blockchain, in particular to a traceability system and method based on the combination of blockchain and Internet of Things. Background technique [0002] The authorized announcement number is CN 205793071 U (application number is 201620737847.2, and the application date is 2016 / 07 / 11), which discloses a system that can play anti-counterfeiting and traceability video by scanning codes on smart mobile terminals of the Internet of Things, including for collecting Original anti-counterfeit traceable video data video collector, mobile Internet, anti-counterfeit traceable server and IoT smart terminal for scanning the identity mark on the carrier or carrier packaging. The video collector includes a video camera and a hard disk recorder. The video collected by the video collector will be The data is transmitted to the anti-counterfeit traceability server through the Inte...
