Smart city data sharing system and method based on blockchain

Abstract

The invention discloses a smart city data sharing system and method based on a block chain. Urban road satellite images and road condition broadcast information are collected and stored in a traffic data unit of the smart city data module. Power market transaction information is collected and stored in a power data unit of the smart city data module; air indexes and urban gaseous pollutant generation information are collected and stored in an ecological data unit of the smart city data module; and the current urban road satellite image and the road condition broadcast information are updated to a traffic data unit through a data updating module according to the set frequency, the current electricity market transaction information is updated to an electricity data unit, and the current airindex and the urban gaseous pollutant generation information is updated to an ecological data unit. According to the method, the block chain technology and the data sharing technology are combined, sothat a user does not need to worry about privacy leakage after querying, and it is guaranteed that query records cannot be tampered.

Description

technical field [0001] The present invention relates to the field of smart city data sharing based on blockchain, in particular to a smart city data sharing system and method based on blockchain. Background technique [0002] With the continuous development of society, the population of cities is increasing, especially in the period of accelerated urbanization. In order to achieve the goal of sustainable development of cities, building smart cities and implementing data sharing has become an indispensable part of urban development in the world. One of the missing means. With the operation of smart city construction, the way to realize data sharing in smart cities is mainly to process all aspects of data according to the same method and model through a unified data sharing platform. After this method transfers data to the data sharing platform, The privacy of some individuals and organizations is easily leaked or even illegally used. If the data is not updated for a long tim...

Problems solved by technology

[0003] At present, the data sharing methods of smart cities are relatively simple, and the same method for processing various data will cause some data distortion or insufficient sharing.

For example, the storage and sharing of image data is often affected by the interference of image acquisition equipment and external environmental noise during the digitization and transmission process, and the final image obtained by the user may be blurred; in terms of air quality, due to the limited number of urban air monitoring points , and the air quality in different locations of the same city may be quite different. At this time, using the same system to share the same data will not achieve the practical purpose, so the data sharing methods need to be continuously enriched
