Medical information sharing authentication method based on block chain

Abstract

The invention discloses a medical information sharing authentication method based on a block chain, and relates to the technical field of the block chain. The method comprises the following steps: a doctor diagnoses a patient and stores a whole-course diagnosis result in a system provided by a medical institution, the doctor cannot create an electronic medical record, only the medical institutioncan create the electronic medical record and store an electronic medical record signature in an off-chain database, and then the storage address signature of the electronic medical record in the off-chain database is broadcasted to a block chain; visitors for the block chain and the off-chain database are only medical institutions; a doctor submits an application to a medical institution where thedoctor is located, the medical institution accesses the data on the block chain to obtain the address of the patient electronic medical record in the off-chain database, accesses detailed data of thepatient electronic medical record in the off-chain database, and finally sends the detailed data to a legal doctor through an internal system of the medical institution. The method has the advantagesof no forgery, anonymity, no tampering, no repudiation, traceability and the like.

Description

technical field [0001] The invention relates to the technical field of blockchain, in particular to a blockchain-based medical information sharing authentication method. Background technique [0002] With the rapid development of the economy and the continuous improvement of the degree of social informatization, data has shown an explosive growth trend, and the value of data has been significantly improved, providing important support for the national economy, life, military, medical and other fields. Especially in the field of medical services, due to the rapid increase of people's attention to health and the rapid development of electronic medical information technology, massive medical data is created and urgently needs to be safely stored and shared, and medical data is sensitive. A large amount of medical privacy information, such as basic information, health status, disease development, and diagnosis and treatment, is related to the vital interests of patients. Once le...

Problems solved by technology

[0004] There are a large number of encryption technologies applied to medical institutions in the prior art, but the current medical information sharing authentication schemes mainly have the following problems: On the one hand, the authentication technology is highly dependent on a single authentication center, which is easy to cause a single point of failure

On the other hand, it is difficult to make operation records open and transparent, and it is difficult to trace the identity of visitors, and there are still potential security attacks and threats
