Medical data transaction system and method based on block chain

Abstract

The invention discloses a block chain-based medical data transaction system and method, and the system is based on a block chain technology, and comprises a data layer which is used for building a set of personal medical data accounts on a block chain for each user; the contract layer is deployed with a data desensitization contract, a data collection contract and a pricing contract and is used for collecting medical data of each user from the data layer, and miners of a public network desensitize the medical data of the users according to the data desensitization contract; classifying the desensitized medical data according to labels according to a data collection contract, and packaging the medical data with the same label into commodities; and finally pricing all the commodities through a pricing contract. The application layer is used for displaying all commodities and receiving query and transaction operations of a data demander; the method has the advantages that the ownership relation is bound through the block chain, unification of the ownership and the use right of personal medical data is achieved, data desensitization is carried out, the data are collected into data commodities, and ordered transaction of the medical data is achieved.

Description

technical field [0001] The invention belongs to the technical field of block chain, and specifically relates to a system and method for medical data transaction based on block chain. Background technique [0002] The blockchain has the characteristics of decentralization, openness and transparency, cannot be tampered with, recorded by timestamp, and easy to trace. Therefore, it is widely used in various fields. [0003] In recent years, with the development of electronic medical records, hospital cloud, remote consultation and other services, patients' medical records and other information have gradually been converted into electronic versions, and more and more personal medical information has been connected to the network. Although this greatly improves convenience, it also increases the risk of patient information data leakage. On the one hand, medical data is of great value to both commercial insurance and research institutions. On the other hand, data holders cannot tr...

AI Technical Summary

Problems solved by technology

On the one hand, medical data is of great value to both commercial insurance and research institutions. On the other hand, data holders cannot trade their own medical data because holders lack data processing capabilities, and personal microdata are difficult to commercialize

Therefore, a large number of medical data theft and reselling have been spawned, and the identity information of the data owner will also be exposed, resulting in extremely bad social impact
