Abstract

The invention relates to the technical field of block chains, and discloses a medical data sharing system based on an IPFS (Internet Protocol File System) and an alliance chain, which comprises a block chain system configured with block chain core service modules and respectively used as peers to organize and form the block chain system, in hospitals and data service companies, ACC and ISC are configured; the patient client is used for sharing the medical data of the patient in the ACC and setting the access permission and incentive cost corresponding to the medical data when accessing the blockchain core service module configured in the hospital; and the data user client is used for querying the target medical data and the corresponding access permission through the ACC when accessing theblockchain core service module configured by the data service company. According to the invention, safe storage and sharing of medical data and authorization management in the sharing process are realized.

Description

technical field [0001] The invention relates to the technical field of block chain technology and electronic medical data security sharing, in particular to a medical data sharing system based on block chain smart contracts. Background technique [0002] Medical data is the original medical information with important value formed by the patient during the medical treatment process, which includes the patient's medical history, medical records and other privacy-sensitive personal data. The sharing of medical data can improve the accuracy and efficiency of disease diagnosis, and has important reference and scientific research value for disease research. In real life, a large amount of medical data is stored in hospital databases. Due to the lack of an effective trust mechanism and incentive mechanism, medical institutions refuse to share their data, which leads to the difficulty of sharing medical data. [0003] Therefore, how to ensure the safe storage and sharing of medical...
