Privacy protection multi-side diagnostic model fusion method and system, and cloud server

Abstract

The present invention belongs to the technical field of information safety, and discloses a privacy protection multi-side diagnostic model fusion method and system, and a cloud server. The system comprises a credible mechanism, a cloud server and a medical center terminal. The credible mechanism completes system initialization to provide system parameters and secret key distribution for the medical center terminal and the cloud computing server, the cloud computing server stores encrypted data resources and fuse local diagnostic models to generate a global diagnostic model, the medical centerterminal generates the local diagnostic models, sends the local diagnostic models through encryption to the cloud computing server and is used for fusion computing task published by the cloud computing server, and the medical center terminal and the cloud computing server can perform bidirectional authentication in the service. The privacy protection multi-side diagnostic model fusion method and system, and the cloud server can achieve privacy protection of the local diagnostic models and case data resources of the medical center, can improve the system efficiency and can be used to provide convenient and private online medical service for users in the real life.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a privacy-protected multi-party diagnosis model fusion method and system, and a cloud server. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: With the development of data mining technology and the popularization of smart wearable devices, online medical diagnosis has appeared in people's daily life. Compared with traditional medical methods, online medical diagnosis breaks geographical restrictions, shortens the time for users to seek medical treatment, and provides users with a new way of seeking medical treatment. However, in the traditional online medical diagnosis system, the medical center server collects and analyzes the user's case data to form a local diagnosis model to provide services for the user. Due to the limited case data owned by a single medical center terminal, the generat...

Problems solved by technology

This method ensures the security of the identity of the user who accesses the data, but since the data is not encrypted, once it is stolen during transmission, it will cause data leakage

[0003] To sum up, the problems existing in the existing technology are: the existing online medical diagnosis service method has a single diagnosis model, and there is no encryption in the data transmission process; in the application, it will cause low diagnosis accuracy, data leakage, and
