Medical data intranet and extranet interaction safety protection method based on a block chain technology

Abstract

A medical data intranet and extranet interaction safety protection method based on a block chain technology comprises the following steps that step 1, data is uploaded, and a client creates a transaction proposal and sends the transaction proposal to an endorsement node; the endorsement node executes the chain code, and generates a read-write operation set based on the read and written Key; the endorsement node returns a proposal result to the client; the client submits a transaction proposal to the sorting node, wherein the transaction content comprises a read-write operation set from a proposal result; the sequencing node encapsulates the sequenced transaction proposal into a block; wherein the block is to be sent to an acknowledgement node; and step 2 data access is carried out: 1) personal medical data: the user selectively opens part of private data to a specified doctor or a specified medical institution for access as required, and 2) institution data: the institution selectivelyopens part of private data to a specified institution or a specified person for access, so that the method has the advantages of data security and tamper resistance.

Description

technical field [0001] The invention belongs to the technical field of medical Internet and block chain, and in particular relates to a security protection method for the interaction between internal and external networks of medical data based on block chain technology. Background technique [0002] At present, the existing background technology is as follows: [0003] Internet + medical and health services: At present, there are business operations such as using mobile phones to inquire about patients' diagnosis and treatment information in hospitals, to make appointments and registrations, and to pay fees; [0004] Gatekeeper's internal and external network security isolation technology: This technology is to solve the protection method for hospital information system and data security in the interaction of data between internal and external networks; [0005] Blockchain technology: distributed data storage, point-to-point transmission, consensus mechanism, encryption alg...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a security protection method for the interaction of medical data inside and outside the network based on block chain technology, which solves the problem of the patient's medical information when the user uses the Internet to obtain his own diagnosis and treatment information in the hospital's internal system. The problem of data leakage and tampering of medical information has the advantages of data security and anti-tampering
