Embodiment Construction

[0043] The inventors of the present application found through a lot of research and practice that in the traditional spatial data sharing method, there is a huge data leakage during the process of data transmission and processing on the sharing platform, and as people pay more and more attention to data privacy and There is an urgent need for cross-calculation of massive data, and data sharing between different departments and units has become an urgent problem to be solved. The aim is to find a technology that can effectively use multi-party data for calculation and analysis while ensuring data privacy. means.

[0044] In order to achieve the above object, the main idea of ​​the present invention is as follows:

[0045]First, the control server receives the request sent by the front end, and distributes the request to the participating nodes of the secure multi-party calculation, and then the two parties participating in the calculation preprocess their respective data, that ...

Abstract

The invention discloses a spatial data distribution mode analysis method based on secure multi-party computing. First, the control server receives the request sent by the front end, and distributes the request to participating nodes of the secure multi-party computing, and then the computing initiator and computing receiver Respectively convert the data to be used for secure multi-party calculations into preset point types; then the calculation initiator and the calculation receiver obtain the secure multi-party calculation results through the obfuscation circuit generated based on the Boolean circuit and the execution of the inadvertent transmission protocol, and then the initiator Post-process the safety calculation results to obtain the final calculation results, then randomly generate any point data in the minimum circumscribed rectangle of the local data, and generate simulated values ​​through the aforementioned steps, and finally, according to the relationship between the observed value and the simulated value, the participating The spatial data distribution pattern of the nodes is analyzed, and the method of the present invention does not leak the data of both sides of the calculation, effectively protecting the privacy of the data.

Description

technical field [0001] The invention relates to the cross-technical field of cryptography and spatial information, in particular to a method for analyzing spatial data distribution patterns based on secure multi-party computing. Background technique [0002] With the rapid development of informatization in various industries, the application fields of basic geospatial data such as regional road network data and population distribution data are becoming more and more extensive, and the integration with various industries is becoming more and more closely. Geospatial basic data has been widely used in various fields such as urban planning, road network planning, and population layout, and the demand for data is large. [0003] In the process of implementing the present invention, the inventor of the present application found that the method of the prior art has at least the following technical problems: [0004] In traditional spatial data sharing, each data holder generally ...
