Embodiment Construction

[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0051] refer to figure 1 , the system of the present invention includes two modules of a medical diagnosis server and a medical user terminal. in:

[0052] The medical diagnosis server completes system initialization, provides registration for medical users, stores nonlinear support vector machine SVM model data built using existing medical databases, receives service query requests sent by medical user terminals, calculates query response results, and sends For medical user terminals;

[0053] The medical user terminal sends an encrypted service query request to the medical diagnosis server, receives the query response result sent by the medical diagnosis server, and performs a decryption operation on the response result to obtain a pre-diagnosis result;

[0054] The medical diagnosis server includes: a system initialization and registration module, a dat...

Abstract

The invention discloses a two-way privacy protective system and method for inquiring a medical diagnostic service, used for mainly solving the problem that privacy protection of inquiry information of medical users and data resources of service providers are not related in the prior art. The system comprises a medical diagnostic server and a medical user terminal; the medical diagnostic server completes system initialization, provides login and distributes a secrete key to the medical user terminal, stores data of a nonlinear SVM model built by using the existing medical database, provides a privacy protective medical diagnostic service for the medical user terminal, and sends an inquiry response result to the user terminal; and the medical user terminal sends a service inquiry request to the medical diagnostic server and performs decryption and polynomial aggregation operation of the inquiry response result returned by the medical diagnostic server, such that a pre-diagnosis result is obtained. According to the invention, privacy protection of the inquiry information of the medical users and the data of the nonlinear SVM model can be realized; and the system and the method can be used for providing an online disease prediction service for the medical users.

Description

technical field [0001] The invention belongs to the field of information security technology, and specifically relates to a privacy protection technology for medical users and service providers, which can be used to provide accurate and efficient medical diagnosis services for medical user terminals under the background of big data, and realize query information and Effective privacy protection of service provider data assets. Background technique [0002] With the development of machine learning algorithms and the universality of network terminal equipment, medical diagnosis systems can provide users with diagnostic services anytime and anywhere, bringing great convenience to people's lives. The support vector machine classification algorithm can deal with large data sets in high-dimensional space, and has been widely used in medical diagnosis service query systems. The traditional medical diagnosis service is that when a medical user terminal requests a medical diagnosis ...
