Smart city data sharing system and method based on blockchain

Abstract

The invention discloses a smart city data sharing system and method based on blockchain, which collects urban road satellite images and road condition broadcast information and saves them in the traffic data unit of the smart city data module, and collects electricity market transaction information and saves them in the smart city data module. In the power data unit of the city data module, air index and gas pollutant generation information in the city are collected and saved to the ecological data unit of the smart city data module. According to the set frequency, the current urban road satellite images and traffic conditions are updated through the data update module. The broadcast information is updated to the traffic data unit, the current electricity market transaction information is updated to the power data unit, and the current air index and gas pollutant generation information in the city are updated to the ecological data unit; the present invention uses blockchain technology and data sharing technology to combine , so that users do not have to worry about the leakage of privacy after making inquiries, and it also ensures that the inquiry records cannot be tampered with.

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
