Abstract

The invention provides an Internet of Things data management method based on a block chain. The method comprises the following steps: carrying out the identity authentication of an Internet of Things terminal through an Internet of Things platform, obtaining the Internet of Things data of the Internet of Things terminal after the authentication is passed, and transmitting the data to a branch division module; the branch division module divides the Internet of Things data into a plurality of branches according to data attributes of the Internet of Things data and sends the branches to the snapshot generation module, and the snapshot generation module splits the Internet of Things data in each branch into a plurality of snapshot files and sends the snapshot files to the block chain network; and the block chain network calculates a hash value of the snapshot file, and stores the snapshot file into the interstellar file system based on the hash value. According to the Internet of Things data management method based on the block chain, the storage cost is low, the safety is high, the efficient storage of the Internet of Things data can be realized, the operation and transaction of the data owning user on the data can be realized, and the utilization rate of data resources is improved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based Internet of Things data management method. Background technique [0002] With the continuous development and wide application of IoT technology, the total amount of data generated by IoT devices has increased significantly. Existing IoT devices have limited computing, storage, and bandwidth, making large-scale IoT device management and data storage a headache. How to realize the effective identification of the Internet of Things device network, ensure the security of information transmission, and effectively manage the data generated by the device is a problem that needs to be solved in many Internet of Things application scenarios, and the decentralized characteristics of the blockchain and The use of asymmetric encryption algorithms can effectively reduce the maintenance cost of the Internet of Things system, and at the same time improve the network's ...
