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 failure to protect user privacy
[0004] The difficulty and significance of solving the above technical problems: traditional secure multi-party computing and other technologies cannot balance privacy protection and data processing efficiency well, and anonymization technology will bring large communication overhead
The use of the above technologies cannot meet the characteristics of large amount of data, real-time diagnosis and timely feedback in the fusion of diagnostic models

Embodiment Construction

[0089] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0090] Aiming at the problem that the existing online medical diagnosis service method has a single diagnosis model and no encryption in the data transmission process; in the application, it will cause low diagnosis accuracy, data leakage, and failure to protect user privacy; the present invention proposes a privacy-protected multi-party diagnosis model Fusion method: under the premise of ensuring the privacy of the local diagnosis model of the hospital, the local diagnosis models of each medical center are fused to generate a more accurate global diagnosis model.

[0091] The application principle of the present invention wi...

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...
