Medical data management method and system based on medical blockchain

Abstract

The invention relates to the technical field of block chains, and discloses a medical data management method based on a medical blockchain, which comprises the following steps: calculating performanceand reliability of all nodes in the block chain, and dividing the nodes into full nodes and light nodes according to the performance and reliability of the nodes of the block chain; grouping the blocks in the block chain by using a block grouping strategy based on full nodes and light nodes to obtain a medical block chain suitable for medical data; storing the medical data by utilizing a medicalblock chain; performing integrity checking on the medical data stored in the block chain by utilizing a data integrity checking method based on the block chain; and performing medical data circulationby utilizing a data transaction algorithm based on the block chain, thereby realizing medical data management based on the medical block chain. The invention further provides a medical data management system based on the medical block chain. According to the invention, the management of the block chain data is realized.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a medical data management method and system based on medical block chains. Background technique [0002] The development of science and technology has promoted the progress of society, which has triggered technological changes, and the blockchain has gradually entered people's field of vision. At present, blockchain technology has achieved great success in data sharing and data traceability due to its characteristics of decentralization, safety, reliability, and non-tampering, and has become a new trusted data carrier. Data in the medical industry has the problem of messy data and more effective data privacy protection, and the application of blockchain technology in the medical industry is still in its infancy. Therefore, how to use blockchain to process data in the medical industry has become a current research topic. hot topics in the field. [0003] Although th...
