Privacy-preserving medical diagnosis and treatment system based on non-deterministic finite automata

Abstract

The invention relates to a privacy protection medical diagnosis and treatment system based on non-deterministic finite automata. Including the key generation center, which is responsible for generating public parameters of the system, distributing the private key of the server, the public / private key of the user, and performing telemedicine authorization operations; hospitals, designing different medical models for different diseases, and encrypting them The model is outsourced to the cloud platform to provide remote diagnosis and treatment services; patients send encrypted medical data to the cloud platform to request diagnosis and treatment services, and use their own keys to decrypt the diagnosis and treatment results returned by the cloud server; the cloud platform provides encryption for hospitals The storage service of the medical model; the computing server, when receiving the patient's remote diagnosis and treatment request, the computing server and the cloud platform interact to execute the secure outsourcing computing protocol, and calculate the best encrypted treatment process. The invention can recommend the best encrypted treatment suggestion for the patient without revealing the privacy of the patient.

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
