Example Embodiment

[0056] Example 1

[0057] figure 1 is the flowchart of the blockchain-based medical data sharing method according to the embodiment of the present invention, such as figure 1 As shown, the blockchain-based medical data sharing method provided by the embodiment of the present invention includes the following steps:

[0058] 101. Construct a P2P network with multiple medical nodes.

[0059] Since the public and private keys are limited to trusted alliance members, if an efficient and secure P2P network is built, the consensus of the medical data sharing node can be achieved. Therefore, in this step, a reliable P2P network with multiple medical nodes should be constructed. The medical nodes here include hospitals or other medical structures that require medical data sharing, and the medical nodes here can be selected as many as possible and as comprehensive as possible. subject to special restrictions.

[0060] Specifically, a P2P network with multiple medical nodes is const...

[0081] Example 2

[0082] figure 2 is the flowchart of the blockchain-based medical data sharing method provided in Embodiment 2 of the present invention, such as figure 2 As shown, the blockchain-based medical data sharing method provided by the embodiment of the present invention includes the following steps:

[0083] 201. Use the Kademlia protocol to build a P2P network with multiple medical nodes.

[0084] Kademlia is a structured P2P overlay network, which belongs to a distributed hash table (DHT) technology. It uses a unique XOR algorithm (XOR) as the basis for distance measurement to establish a DHT network topology. High routing query speed.

[0085] It should be noted that, in addition to the manners described in the above steps, step 201 may also implement the process in other manners, and the embodiments of the present invention do not limit the specific manners.

[0086] 202. Use the patient's ID number as the patient's unique identification number, use the n...

Abstract

The invention discloses a medical data sharing method and device based on a block chain, and belongs to the technical field of the block chain. The method comprises the following steps: constructing aP2P network with multiple medical nodes; generating a public key and a private key for the patient by using SM2 according to a unique identification number defined and selected for the patient, wherein the patient reserves the private key and opens the private key to multiple medical nodes, and a predetermined medical node in multiple medical nodes encrypts the medical data information of the patient by using the public key so as to construct structural information of the block chain through the ciphertext; broadcasting the structural information to other medical nodes of multiple medical nodes according to mutually agreed preset confirming checking rule; and writing the structural information into the block chain. Through the medical data sharing method disclosed by the invention, the data sharing efficiency between the hospitals can be improved, and the privacy and the security of the information can be guaranteed from the technology, and the method is suitable for extensively popularizing and applying in the medical field.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a method and device for sharing medical data based on blockchain. Background technique [0002] With the development of medical and health services, remarkable achievements have been made in domestic medical informatization construction, and the informatization degree of most third-level hospitals and some advanced second-level hospitals is already very high. The main medical business information systems include: hospital information system, electronic medical record system, medical image archiving and communication system, inspection information system, ultrasound information system, ECG network system, physical examination management information system, etc. [0003] The construction of the above-mentioned information system has completed the first step of medical informationization, and gradually realized the collection and storage of medical business data. The con...
