Description

Technical Field

[0001] The present invention relates to the fields of privacy computing and highway engineering information technology, and in particular to a method and system for sharing highway engineering information data based on privacy computing. Background Art

[0002] In the highway engineering industry, a large amount of important engineering information data is generated during engineering surveys, measurements, and field investigations. For a long time, this data was primarily recorded through manual surveys and paper records. In recent years, with the rapid development of digital transportation, some companies in the industry have developed engineering survey information systems and field investigation systems based on technologies such as BIM and GIS, accelerating the digital transformation of highway engineering. However, various current information systems still have certain pain points:

[0003] (1) The ownership of data is not clearly defined. Although a lot of data can be obtained within the same unit, due to the protection of national security and commercial secrets, the initiative and enthusiasm of each unit to participate in data circulation and sharing are very low. Ultimately, a series of unit-level "data islands" are formed, making it difficult to achieve information reuse and comprehensive analysis applications, and unable to fully realize the economic and social value of data, resulting in a waste of social resources.

[0004] (2) Data management and application are parallel and separated. A large amount of multi-source heterogeneous data lacks linkage in application, resulting in repeated data collection. The same data is stored multiple times in databases with different needs and projects, forming "data islands" at the unit level. Summary of the Invention

[0005] The purpose of the present invention is to provide a method and system for sharing highway engineering information data based on privacy computing. By adopting this solution, privacy computing can be used to ensure that the data provider does not leak the original data, and the data can be analyzed and calculated. This can effectively solve the pain points of highway engineering information systems, ensure that engineering data is "available but invisible" throughout the entire life cycle of the project, break down existing data barriers, and safeguard data reuse and integration.

[0006] The present invention is achieved through the following technical solutions:

[0007] A method for sharing highway engineering information data based on privacy computing, the method comprising the following steps:

[0008] Establishing a shared database and importing data collected by data providers into the shared database, wherein the collected data is highway engineering information;

[0009] The shared database calculates the data in the database through privacy computing to obtain a calculation result;

[0010] Based on the calculation results, the shared database performs a first information sharing process and a second information sharing process for different entities:

[0011] The first information sharing process includes: displaying the imported data, calculation process and calculation results to the data provider and making them available for the data provider to call;

[0012] The second information sharing process includes: providing the calculation result to the non-participating data provider under the authorization of the data provider.

[0013] Further optimization, after the data collected by the data providing parties are imported into the shared database, the following steps are also included:

[0014] The shared database needs to review each data provider, evaluate its exploration and investigation capabilities, and retain the data imported by the data providers that meet the evaluation criteria.

[0015] Further optimization, after retaining the data imported by the data providers that meet the evaluation criteria, also includes the following steps:

[0016] According to different types of data, the retained data is checked for legitimacy and processed in a unified manner.

[0017] Further optimization, the privacy computing also includes the following functional modules: joint statistics module, joint query module, joint BIM+GIS three-dimensional modeling module and joint computing module.

[0018] Further optimization, after obtaining the calculation results, further comprising the following steps:

[0019] After obtaining the calculation results, if the subsequent data provider questions the calculation results, he / she shall submit an information question and information correction application to the database so that the database can update the data.

[0020] Further optimization, the database also includes a privacy computing interface, which can be called by the self-developed system of the data provider, and obtain the data and calculation results provided by each data provider through the self-developed system for processing.

[0021] Further optimized, the self-developed system obtains data from the privacy computing interface through secret sharing, homomorphic encryption, oblivious transmission, obfuscated circuits or zero-knowledge proof.

[0022] Further optimized, the second information sharing process further includes the following specific steps:

[0023] The non-participating data provider needs to provide calculation parameters and call the corresponding function module. Then, under the authorization of the data provider, the corresponding function module calculates the calculation result and provides the calculation result to the non-participating data provider.

[0024] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0025] This invention provides a method and system for sharing highway engineering information data based on privacy computing. This solution uses privacy computing technologies such as multi-party secure computing and federated learning to import highway engineering information data collected by various units, including surveys, measurements, and field investigations, into a privacy computing platform. Without leaking the original data of each party, this method enables joint statistics, joint queries, joint calculations, and analysis among different units. Through interfaces, privacy computing functions of internally developed systems can also be implemented. This invention significantly promotes the open sharing, exchange, and circulation of highway engineering information data resources, breaking down data barriers and improving engineering efficiency while fully realizing the value of data and saving social resources.

It should be understood that the following drawings only illustrate certain embodiments of the present invention and should not be considered as limiting the scope. A person of ordinary skill in the art can also derive other relevant drawings based on these drawings without inventive effort. In the drawings:

[0028] Figure 2 The present invention provides a flowchart of an embodiment. DETAILED DESCRIPTION

[0029] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0030] Example 1

[0031] This embodiment 1 provides a method for sharing highway engineering information data based on privacy computing. The specific sharing method includes the following steps:

[0032] In this embodiment, a shared database is first established. Since each unit, that is, each data provider, will collect highway engineering information data such as survey, measurement, and field investigation respectively, the data collected by each data provider needs to be imported into the shared database, where the data provider is the unit providing the data. After each data provider imports the data into the shared database, it is necessary to strictly review the units providing the highway engineering information data, evaluate their survey and call capabilities, and then adopt and retain the data provided by the units that meet the evaluation conditions, and then perform legality detection and unified processing on different types of data.

[0033] After legality detection and unified processing, calculations need to be performed based on the characteristics of the highway project, based on the functional modules provided by privacy computing, including but not limited to the following: such as joint statistics module, joint query module, joint BIM+GIS three-dimensional modeling module and joint calculation module, etc., so as to obtain the respective calculation results through the above functional modules; the joint calculation also includes load calculation, deformation calculation and finite element calculation, etc.

[0034] When a certain number of units have overlapping projects in a certain area, the system can obtain massive structured regional data after uniformly processing the data provided by each unit.

[0035] After obtaining the calculation results through privacy computing technologies such as multi-party secure computing and federated learning, the shared database will perform and implement the first information sharing processing and the second information sharing processing for different subjects, where the different subjects include data providers and non-participating data providers; the implementation method of the first information sharing processing is: the parties participating in providing data can obtain the authority of joint statistics, joint queries, joint modeling and various types of highway engineering calculations in the system. This authority can call the data of the entire area to meet the needs, that is, call all data such as imported data, calculation process and calculation results; the implementation method of the second information sharing processing is: units that do not participate in providing data can apply to the system platform to use various functions. By paying usage fees and other means, with the authorization of each data provider, they can also use the various functions based on existing data in the system, that is, enter calculation parameters into the database, select the required functional modules, and then query the corresponding calculation results, thereby ensuring that the above data is "available but invisible" at the non-participating providers.

[0036] In this embodiment, there is also a unit that provides data subsequently, that is, a subsequent data provider. If the unit that provides data subsequently has doubts about the calculation results of the existing data in the database, especially for highway engineering information that is prone to change, it can submit an application for information doubt and information correction, which is conducive to the continuous and stable update of the original data of the entire database.

[0037] The above database can use the highway engineering information such as survey, measurement, and field investigation of various units as the data party, through multi-party secure computing, federated learning and other privacy computing technologies, supplemented by underlying cryptographic technologies such as obfuscated circuits, secret sharing, and oblivious transmission, with the privacy computing platform as the computing party, to achieve the "available but invisible" highway engineering information data, and conduct multi-party collaborative analysis, processing, calculation and result release of multi-source heterogeneous engineering data, to achieve joint statistics, joint query, joint BIM+GIS modeling and various highway engineering calculation needs.

[0038] Example 2

[0039] This embodiment 2 is further optimized based on embodiment 1 and provides a specific implementation method.

[0040] like Figure 1 As shown in the figure, multiple units import highway engineering information data collected through surveying, measurement, and field investigation into the database. In other words, in the privacy computing platform, the weight of each unit's data varies. For example, unit A provides 40% of the survey data and 30% of the field investigation data for a certain highway, while unit B provides 30% of the survey data and 20% of the field investigation data for another highway, and unit C provides 50% of the survey data and 40% of the field investigation data for a certain highway, and so on.

[0041] Since there is another unit E that needs a large number of geological and hydrological calculation parameters for the finite element calculation model of a certain highway project, and the comprehensive data collected by unit ABCD during the survey process can just provide all the data required for the model, unit E can directly apply for the finite element calculation module of the privacy protection computing system, submit the application and structural parameters, and wait for the platform to send the calculation results to the corresponding account.

[0042] During the entire process, users are separated from the original calculated data, and "data is available but not visible". At the same time, this process can improve efficiency, reuse data, avoid waste of resources, and ensure the correctness of parameters in the platform, and the calculation results are highly accurate.

[0043] Example 3

[0044] This embodiment 3 further optimizes the embodiment 2 and provides a specific implementation method.

[0045] like Figure 2As shown in the figure, after the data providing unit imports its internal highway engineering information, such as engineering survey, engineering measurement, field investigation and other data into the database, that is, the privacy computing platform, there are still some confidential data within a certain unit that cannot be shared or the sharing process is complicated. Therefore, the database can provide a privacy computing interface to each unit's self-developed system. The self-developed system is the survey information system, field investigation system, etc. developed by each unit. When operating the self-developed system within the unit, the calculation results of the collaborative calculation and analysis of the data held by each department can be obtained by calling the privacy computing interface, and query and statistics can be performed in the self-developed system. The self-developed system can obtain data from the privacy computing interface through secret sharing, homomorphic encryption, oblivious transmission, obfuscated circuits or zero-knowledge proof, etc.

[0046] Example 4

[0047] This embodiment 4 further optimizes the embodiment 3 and provides a highway engineering information data sharing system based on privacy computing.

[0048] A sharing system platform is established in this sharing system, and a database is established in the sharing system platform. The party providing data, the party not providing data, and the party providing data later can all obtain their respective data through the above sharing method, thereby realizing a minimum technical solution for a highway engineering information data sharing method based on privacy computing, as described in Example 1, for the purpose of "using privacy computing technologies such as multi-party secure computing and federated learning, supplemented by underlying cryptographic technologies such as obfuscated circuits, secret sharing, and oblivious transmission, with a privacy computing platform as the computing party, to achieve the availability and invisibility of highway engineering information data."
