Privacy protection medical diagnosis and treatment system based on non-deterministic finite automaton

Abstract

The invention relates to a privacy protection medical diagnosis and treatment system based on a non-deterministic finite automaton. The system comprises a key generation center which is responsible for generating system public parameters, distributing a private key of a server and a public / private key of a user and executing remote medical authorization operation; a hospital which is used for designing different medical models for different diseases and outsourcing the encrypted medical models to the cloud platform so as to provide remote diagnosis and treatment service; a patient who sends the encrypted medical data to the cloud platform to request to obtain the diagnosis and treatment service, and decrypts the diagnosis and treatment result returned by the cloud server by using the own key; a cloud platform which is used for providing storage service of the encrypted medical model for the hospital; and a computing server which is used for interactively executing a security outsourcing computing protocol by the computing server and the cloud platform after receiving a remote diagnosis and treatment request of the patient, and calculating an optimal encryption treatment process. The optimal encryption treatment suggestion can be recommended to the patient, and the privacy of the patient cannot be leaked.

Description

technical field [0001] The invention relates to a privacy protection medical diagnosis and treatment system based on non-deterministic finite automata. Background technique [0002] Many social problems are exacerbated by an aging population and the prevalence of chronic diseases. Telediagnosis and treatment systems can be used to alleviate these social problems: using information technology to remotely provide accessible, low-cost and high-quality clinical medical services, so that patients can continue to receive treatment at home, and obtain medication and treatment advice in a timely manner through the telediagnosis and treatment system . Medical IoT plays a key role in telediagnosis by deploying wireless wearable (or implantable) sensors on patients to collect vital signs and physiological data. The monitored physiological parameters are sent remotely to hospitals for medical diagnosis, thereby providing quantitative disease data that is richer than simple disease des...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the problems in the existing medical diagnosis and treatment plan: the level of privacy protection is not high, it is difficult to provide treatment process suggestions under the premise of ensuring data privacy, and complex preprocessing and multiple rounds of interaction are required, etc., to provide a Privacy-preserving medical diagnosis and treatment system based on non-deterministic finite automata
