A medical data authorization method based on a block chain technology

Abstract

The invention discloses a medical data authorization method based on a block chain technology. The method comprises the steps that a patient, a doctor and a requester generate IDs through real-name authentication and related supervision mechanism authentication respectively, identity private keys are generated through a random number generator respectively, identity public keys corresponding to the identity private keys are calculated according to the identity private keys, and the identity public keys and the IDs are uploaded to a block chain; the patient signs an electronic medical record together with a diagnosis and treatment doctor after seeing a doctor, uploads the electronic medical record to the block chain after being encrypted by using a patient identity public key, and creates an authorized intelligent contract; and after the requester initiates an authorization transaction request, the patient triggers an authorization smart contract after verifying the identity, and the requester gets the electronic medical record. The cross-mechanism authorization of the medical data can be realized under the condition of protecting the privacy of the patient, the medical data transfer efficiency is improved, the condition of the patient can be comprehensively known by an incumbent doctor or medical institution, and the medical data authorization method has practical significancefor developing modern remote medical treatment and medicine research.

Description

technical field [0001] The invention relates to a medical data authorization method based on block chain technology. Background technique [0002] Medical data belongs to the privacy of patients. It has been accumulated in the centralized databases of hospitals and other medical institutions for a long time. The isolation of data between medical institutions results in poor information. It is difficult for doctors or medical institutions to fully understand the situation of patients. At present, with the Internet With the development of technology, with the increasing degree of informatization of medical institutions, a large amount of accumulated medical data can be shared, but a little carelessness will lead to serious data leakage, unclear ownership, and medical data belongs to patient privacy. There are ways to protect patient privacy while enabling efficient interoperability of medical data. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the ...
