Abstract

The invention discloses a block chain-based medical data sharing method and device, belonging to the technical field of block chains. The method includes: constructing a P2P network with multiple medical nodes; using SM2 to generate a public key and a private key for the patient according to the unique identification number selected for the patient definition, the patient keeps the private key, and the The public key is disclosed to the plurality of medical nodes; the predetermined medical node in the plurality of medical nodes encrypts the medical data information of the patient with the public key, and constructs the structured information of the block chain through the ciphertext; Broadcasting the structured information to other medical nodes of the plurality of medical nodes according to a consensus preset confirmation verification rule; writing the structured information into a block chain. The invention can not only improve the data sharing efficiency among hospitals, but also ensure the privacy and safety of information technically, and is suitable for wide popularization and application in the medical field.
