Abstract

The invention discloses a medical data security cooperation system based on a block chain, which realizes unified management of medical big data and solves the problem of medical data islands. According to the system, a set of stable, authentic and decentralized medical record data storage system is designed by combining a block chain technology and a cryptography technology; reliable storage of personal electronic health records is ensured by using the decentralized, traceable and tamper-proof core application capability of the block chain; a ciphertext access control strategy for sensitive data is designed by applying cryptography hybrid encryption, attribute encryption and other technologies while reliable storage of personal electronic health records is guaranteed, and personal privacyand data security are fully protected through data desensitization and encryption in the processes of information authentication, broadcasting and transmission. An effective excitation mechanism is also designed, and interconnection and intercommunication and security cooperation of medical big data are realized under the action of the excitation mechanism.

Description

technical field [0001] The invention relates to a blockchain-based medical data security cooperation system, which belongs to the technical field of medical big data security and utilization. Background technique [0002] With the rapid development of information technology, artificial intelligence and data mining technology are becoming more and more mature, and at the same time, the boom of big data is increasing. Data has penetrated into all walks of life and become an important factor of production. While facilitating people's lives, it is also constantly changing the way people live. Medical big data is a typical example. [0003] Medical big data comes from a large number of patients, including sports health data, routine examination data, medical record data, etc., and can be used for scientific research to varying degrees. With the deepening of research in recent years, applications such as electronic medical records, intelligent consultation, precision medicine, di...
