Blockchain-based intelligent medical attack traceability method and medical big data system

Abstract

The embodiment of the present disclosure provides a blockchain-based intelligent medical attack tracing method and a medical big data system. When receiving the abnormal reporting information sent by the blockchain sharing node terminal, the target verification service When there is a network information attack behavior against the target verification service information in the verification process of the smart contract conditions of the information sharing smart contract, the network attack intelligence clues in the attack behavior stage in the multi-attack link data flow of the network information attack behavior are tracked, according to the network The network attack intelligence clues in the attack behavior phase of the multi-attack link data flow of the information attack behavior determine the target verification service information, the attack traceability result information of the network information attack behavior, and then take into account that before the verification process of the smart contract conditions of the smart contract, In view of the possible network attacks on the shared verification service information initiated by the blockchain shared node terminal, the information security monitoring effect of shared access is improved.

Description

technical field [0001] The present disclosure relates to the field of smart medical technology based on big data technology, and for example, relates to a blockchain-based smart medical attack tracing method and a medical big data system. Background technique [0002] In the face of various problems or pain points in the medical and health industry, the combination of blockchain technology and the medical industry, with the characteristics of distributed, non-tamperable, and traceable, can open up the information flow of medical data on the premise of ensuring the privacy of patient data. Improve the status quo of data islands between institutions, rebuild the trust between doctors and patients, and improve the efficiency of the medical industry. [0003] Based on this, in related technologies, medical file sharing can provide more data sharing and data research for a large number of institutions. However, in the process of sharing access, smart contracts can allow credible ...

AI Technical Summary

Problems solved by technology

[0003] Based on this, in related technologies, medical file sharing can provide more data sharing and data research for a large number of institutions. However, in the process of sharing access, smart contracts can allow trusted transactions without third parties, and these The transaction is traceable and irreversible, but it does not take into account the possible network attacks on the shared verification service information initiated by the blockchain shared node terminal before the verification process of the smart contract conditions of the smart contract, resulting in the information security monitoring effect of shared access bad
