Embodiment 1

[0059] The situation of this embodiment is that a university collects some data such as soil temperature and humidity of the campus environment. Then it fills in the basic information of the provided data in the above step 002, the data name, the hash stored on IPFS, the access method, etc., click the Provider Data button, interact with the contract through the API interface, and write the data to the blockchain. In step 003, the detailed data information provided by Beijing University of Technology can be queried.

Embodiment 2

[0061] The situation of this embodiment is that a university now has a data requirement. In step 004, the existing data on the chain is checked, the required data is found, a data request is initiated for it, and the request is waited for the data provider to review. In step 005, the status of the requested data can be queried.

Abstract

The invention discloses a blockchain-based Internet of Things data sharing method. The method involves the following components or processes: S1) an account system module, user registration, user login, user information and user management; S2) data management, a data providing module, a data request module, a task publishing module, a task execution module, a data query module and a task query module; and S3) right management, data access control, data authorization management, and data release check. The method is based on a mainstream browser, and PCs are applied more and more widely, and therefore, users can use the method very conveniently, and the access threshold of the method is low. Compared with a traditional centralized management data sharing system, a decentralized data sharing system saves a lot of data intermediary costs and solves the security problem of centralized management. The trust-free feature of the blockchain technology can assist in solving the problem of mutual trust between Internet of Things data sharing nodes; and an IPFS (Inter-Planetary File System) is adopted, and therefore, the secure storage of massive data can be realized. The method has high expandability.

Description

technical field [0001] The invention relates to the fields of blockchain technology, Internet of Things technology and distributed file storage technology, in particular to the blockchain technology, and realizes a distributed and decentralized Internet of Things data sharing method. Background technique [0002] The Internet of Everything is the future development trend. With the rapid development and wide application of the Internet of Things, the scale of the Internet of Things continues to expand, and the Internet of Things generates massive data. There is a great demand for how to effectively share the Internet of Things data. IoT data sharing is included in the key technology breakthrough project. Data sharing is the key support for the large-scale application of the Internet of Things. For example, smart cities built in global hot spots need to use all kinds of city perception data (such as urban traffic data, environmental data, security data, etc.) obtained by the ...
