Civil air defense data sharing system and method based on block chain

Abstract

The invention discloses a civil air defense data sharing system and method based on a block chain, and the system comprises a data receiving module which is used for receiving keywords and identity information transmitted by a data requester, and receiving shared data of a data provider; a data processing module, used for standardizing and unifying the shared data sent by the data provider, and sending the processed structured data ciphertext and keyword index to the data storage module; a data storage module, used for storing the structured data ciphertext and the keyword index; an identity authentication module, used for carrying out identity authentication on the identity information sent by the data requester; and a data sharing module, used for matching the corresponding data in the data storage module according to the identity authentication result and the keyword and sharing the data to the data requester. According to the invention, data can be prevented from being illegally acquired, used and tampered, and data sharing and secret-related data protection are realized.

Description

technical field [0001] The invention belongs to the technical field of civil air defense data sharing, and in particular relates to a blockchain-based civil air defense data sharing system and method. Background technique [0002] The main function of data sharing is to achieve data sharing between the data owner and the data requester, and realize the equivalent exchange between the service value of the data requester and the data owner. [0003] Traditional data sharing methods mainly include two types: the first type is the distributed service bus exchange method, and the second type is the centralized data sharing method. These two sharing methods are mainly based on regular and quantitative sharing methods, which cannot be updated in real time through data modification, uploading, deletion, etc., and cannot meet the requirements of effective control and supervision of data being used within the specified range and prohibiting illegal use. . In addition, the traditiona...

AI Technical Summary

Problems solved by technology

[0005]1. The data is highly sensitive, and the existing data sharing platforms are untrustworthy, which makes users unwilling and afraid to share open data

[0006]2. There is no relevant system for guarantee, leading to risks such as data leakage during the sharing and opening process, and it is difficult to define responsibilities after leakage

[0007]3. The sharing channels are not smooth, and it is difficult to guarantee the security, confidentiality and sustainability of the data sharing process

[0008]4. The availability of data is low, the data heterogeneity of institutions at all levels is strong, and the data structure is complex
