Embodiment Construction

[0024] The technical problem to be solved by the present invention is how to realize the authenticity of medical and health data, the privacy protection of medical and health data, and the confidentiality of the data exchange process, and how to realize the results of the data can be viewed without revealing the private information of the data source. Use blockchain technology to open standard interfaces to data owners such as various medical institutions, store medical data, and realize data non-tampering; through blockchain to control permissions, to other medical institutions or insurance companies, pharmaceutical companies and research institutions in the system Users of such data open up the viewing authority and data collection authority of medical data sharing; at the same time, based on the big data of the system, expand traditional medical insurance, realize service extension, and provide services such as data analysis, data processing, and data privacy protection;

Abstract

The invention discloses a medical data sharing method based on a block chain, and the method comprises the steps that a medical data owner authorizes to upload personal medical data on the premise of desensitizing private data; medical institutions and hospitals serve as data keepers, unify the format of data through the standard protocol layer, standardize data writing based on the blockchain smart contract, and store the data in the blockchain system; a medical industry ecological data sharing and intercommunicating mechanism is established through the block chain, and alliance members joining the block chain equalize the rights and interests of the shared data after getting through; unified and standardized user medical data are provided for the outside, mechanism nodes on the block chain achieve comprehensive data intercommunication, and effective utilization and privacy protection of the medical data are guaranteed.

Description

technical field [0001] The present invention relates to blockchain technology, in particular to a blockchain-based medical data sharing system and method. Background technique [0002] At present, with the promotion of hospital electronic medical records, hospitals have accumulated a large number of medical and health data of patients, and these medical and health data contain huge value. Therefore, many local governments have established medical and health data sharing and exchange platforms, collecting a large amount of medical and health data. With the promulgation of the "Network Security Law", user medical and health file data belong to the user's privacy data, how to ensure the authenticity and integrity of medical archive data, how to ensure that the exchange of medical data is authorized by the user, and how to ensure data exchange The confidentiality of data in the process is a technical problem that needs to be solved urgently. [0003] Blockchain technology Bloc...
