Intelligent medical attack tracing method based on block chain and medical big data system

Abstract

The embodiment of the invention provides a smart medical attack tracing method based on a block chain, and a medical big data system. The method comprises the following steps of: receiving exception report information sent by a block chain sharing node terminal; when the target verification service information of the block chain sharing node terminal has a network information attack behavior aiming at the target verification service information in the verification process of the smart contract condition of the shared smart contract, tracking a network attack information clue of an attack behavior stage in a multi-attack link data stream of the network information attack behavior; determining attack tracing result information of the network information attack behavior of the target verification service information according to a network attack intelligence clue of an attack behavior stage in a multi-attack link data stream of the network information attack behavior, and before the verification process of the smart contract condition of the smart contract, improving the information security monitoring effect of shared access for network attacks possibly suffered by shared verification service information initiated by a block chain shared node terminal.

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
