Medical data sharing method and device based on blockchain technology, electronic equipment and storage medium

Abstract

The invention discloses a medical data sharing method and device based on a block chain technology, electronic equipment and a storage medium. The method is applied to a medical alliance chain systemand comprises the steps: S1, receiving a user registration request, allocating a unique account Account (a user ID, a user type and user permission) to a user, generating a secret key K {k1, k2} for the user, k1 being a public key of the user in the medical alliance chain system, and k2 being a private key of the user; s2, receiving a data operation request; s3, reading the unique account Accountof the user according to the operation request, and performing verification matching with the user permission corresponding to the Account; and s4, after verification is passed, performing corresponding operation according to the data operation request, and sending, by the access node, the public key to a blockchain node. By means of the blockchain technology, a doctor is the only user capable ofmodifying the medical data content, the real reliability of data on the alliance blockchain is guaranteed, and the consistency of shared data is guaranteed; a patient has the authority of acquiring medical data and setting privacy, so that the safety of privacy information of the patient is ensured, and various problems caused by privacy leakage are avoided; and after the third-party institution passes the alliance authentication, the reliable medical data can be conveniently obtained, and the convenience is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of blockchain, and more specifically, to a medical data sharing method, device, electronic equipment and storage medium based on blockchain technology. Background technique [0002] Medical data includes hospital records, examination results, treatment plans, etc., which are highly sensitive personal privacy information. At present, electronic medical records have been widely used in large and medium-sized cities in China, so that personal medical records can be better preserved in hospitals. Electronic medical records are often associated with the medical cards of various hospitals, and doctors can track patients' medical visits through the information recorded in the medical cards. However, there is still a problem that this information cannot be shared with doctors in other hospitals, and even the loss of the medical card may lead to the loss of personal medical information. For example, if Zhan...
