AI Technical Summary

Technical Problem

Existing technologies struggle to simultaneously meet the demands of efficient global data discovery and strict data sovereignty in the automotive industry. Centralized directories pose single-point failure risks and data sovereignty loss issues, while federated directories suffer from low query efficiency in large-scale environments and fail to meet real-time requirements.

Method used

A hybrid directory management approach is adopted, combining centralized and federated directories through metadata hierarchical and intelligent routing mechanisms to achieve efficient discovery and sovereignty protection of data resources. Specific steps include metadata collection, hierarchical classification, anonymization, differentiated synchronization, query request verification, and intelligent routing decisions, constructing a logically unified but physically distributed directory system.

Benefits of technology

It achieves global data discovery efficiency comparable to centralized solutions while strictly protecting data sovereignty, improves query response speed and reduces synchronization bandwidth consumption, and ensures localized control and security of sensitive data.

Abstract

The application discloses a hybrid directory management method and system for a trusted data space of the automobile industry, aiming at solving the sovereignty protection and query efficiency contradiction of a pure centralized and pure federalized directory architecture. The method is based on a hybrid architecture of participating nodes, centralized directory services and data consumers, and through metadata collection preprocessing and automatic classification, the metadata of the public layer is desensitized and differentially synchronized to the central directory. Combined with DID identity authentication, the query request verification and standardization are completed, the routing engine intelligently selects the query path according to the multi-dimensional cost, the distributed fine-grained authorization is performed on the business / sensitive layer metadata, and finally the multi-source result feedback is aggregated. Experiments prove that compared with the pure federal mode, the query efficiency is improved by 1-2 orders of magnitude, and compared with the pure centralized mode, the synchronization bandwidth is reduced by 97%, realizing the balance between efficient global discovery of data resources and strict sovereignty protection in the automobile industry, and adapting to large-scale collaborative scenarios such as supply chain collaboration.
