A smart city IoT block chain integration mutual trust sharing method

Abstract

The invention discloses a smart city Internet of Things block chain integration mutual trust sharing method, including an Internet of Things data extraction module, an Internet of Things data processing module, a data encryption module, a block chain network construction storage technology module, and a data access authority module , IoT data linkage module, IoT data refresh module and data access and sharing module. The present invention integrates and utilizes the data of smart city Internet of Things applications in cities and between cities, further researches and develops on the basis of it, makes full use of the research and development achievements of various smart city Internet of Things, and promotes the interconnection and intercommunication of Internet of Things data in cities and between cities. The blockchain hash function realizes decentralized confidential storage and quick traceability, dynamically updates and actively and passively shares IoT data, and covers all cities in the country and the world through interconnection and data integration between cities and cities, which belongs to top-level intelligence The top-level application of the urban Internet of Things architecture in the field of Internet of Things technology makes use of various types of Internet of Things data.

Description

technical field [0001] The present invention relates to the technical field of intra-city intercity Internet of Things smart city, in particular to a smart city Internet of Things block chain integration mutual trust and sharing method. Background technique [0002] Current status and bottlenecks of smart city technology: Smart city technology includes public information services, public services, urban planning, municipal construction, public resource services, idle resource services, important materials, smart transportation, production and processing, ecological protection and other fields. There are many researchers, There is no unified standard constraint, each doing its own thing, the data structure and result form it produces are also varied, each doing its own thing, and the level of confidentiality, etc., it is difficult to be compatible, forming a joint force, resulting in a lot of repeated construction and repeated research and development, wasting a lot of social ...
