Medical data sharing method based on block chain

Abstract

The invention provides a medical data sharing method based on a block chain, which comprises the following steps: S1, a node registers a public key on the Internet, the node is a node in an alliance group, and the public key is a 32-bit identifier; s2, the mechanism encrypts the data through a public key and then uploads the data to a database; s3, the client sends a request to the main node, broadcasts the request after receiving the request and reaches a consensus; s4, the data is uploaded to a blockchain database; s5, a block chain is formed by the block, the node is interacted by using aninterface provided by a web, and a private key of the user is encrypted by using a password; s6, when the user inquires the data, an identity authentication mode is adopted, and the user can upload the data and can also inquire the data. According to the decentralized, traceable and tamper-proof data sharing method based on the block chain, the data can be shared, and meanwhile the safety of the data can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a method for sharing medical data based on block chains. Background technique [0002] As people pay more and more attention to health, medical data has become particularly important. At present, more and more new technologies are applied in medical data, such as remote access, electronic storage, etc. But there are still many problems to be solved in the medical field. The first is the storage of medical data. Medical data is the personal privacy of patients. However, many medical data are currently stored on third-party servers. If the third-party server is attacked, the data on the server will be leaked. The second problem is data sharing. If patients, researchers, and medical organizations can share data and ensure data security and non-disclosure, it can help doctors formulate treatment plans according to patients' conditions, and also help researchers stud...

AI Technical Summary

Problems solved by technology

The first is the storage of medical data. Medical data is the personal privacy of patients. However, many medical data are currently stored on third-party servers. If the third-party server is attacked, the data on the server will be leaked.

The second problem is data sharing. If patients, researchers, and medical organizations can share data and ensure data security and non-disclosure, it can help doctors formulate treatment plans according to patients' conditions, and also help researchers study medicine and diseases. provided data source

At present, cloud servers are mainly used to store data. Medical institutions store patients' electronic information and data in the cloud. Although this improves the efficiency of retrieval and shared queries, it also brings the risk of privacy leakage. Organizations with data It directly controls the data, and the data is at risk of being tampered with. Who can query and use the data is also a problem

[0003] Many researchers have begun to study medical and health data systems. Some have proposed a distributed electronic health system model and a medical service model in the cloud, but none of these can guarantee data security.
