TECHNICAL FIELD
[0001] The present application relates to the technical field of human resource data security, and more particularly to a human resource data security sharing method and system. BACKGROUND
[0002] In the process of sharing human resource data, if the platform only relies on redundant field combination for identity verification and lacks dynamic management and control of the credibility of redundant paths, it may be exploited by attackers to induce the system to make false judgments by constructing a "format legal" fake identity.
[0003] This not only causes false identities to mix into shared data, but also causes false identities to be misidentified and banned, thereby causing the redundancy mechanism to be exploited in reverse, the verification system to fail, and ultimately causing data security risks at the platform level.

The segmentation module is used to segment the behavior signal sequence into continuous time-series operation segments according to a unified time sliding window mechanism; for each group of time-series operation segments, feature encoding processing is performed to extract operation frequency, rhythm changes, device fingerprint and interface jump features, and construct the corresponding behavior embedding vector block; The building module is used to embed behavior into vector blocks as nodes in a directed graph, establish behavior transition edges between nodes according to time sequence, and construct a preliminary behavior path graph. The aggregation module is used to perform node pattern similarity calculation on multiple behavior path graphs, aggregate behavior path graphs with similar structures, and uniformly rearrange them into a standardized behavior trajectory structure graph. The index module is used to summarize all standardized behavioral trajectory structure maps, and combine user identifiers, platform sources and time period information to build a trajectory identity matrix index set to support unified retrieval of global trajectory data; The mapping module reads the trajectory identity matrix index set, extracts path credibility and behavior stability information, and sequentially generates trajectory coding block groups, platform embedding vectors, redundant mapping vectors and candidate field sets. Finally, it selects behavior-driven redundant field groups to complete the consistent mapping of trajectory to field space.
