[0002] In the development of public security informatization, data originates from multiple police departments and covers multiple administrative regions. Business information systems developed across various police departments, regions, and historical periods often employ different data standards, storage formats, and naming conventions. This multi-source heterogeneity makes it difficult to directly interoperate, share, and integrate data across regions, police departments, and systems, leading to the long-standing problem of "information silos." Public security data often carries significant legal weight, and its source, generation process, flow path, and relationships with other data (i.e., traceability and interpretability) are crucial. However, in a multi-source heterogeneous environment, data traceability and interpretability present significant challenges. Summary of the Invention

[0003] The present invention provides a public security digital network service method, device, equipment and medium for public security digital objects, which solves the problem of how to improve the data interaction efficiency between public security systems and the traceability and interpretability of data.

DETAILED DESCRIPTION

[0011] To further illustrate the technical means and effects of the present invention to achieve its intended purpose, the technical solutions in the embodiments of this application are clearly described. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this application are within the scope of protection of this application.

[0012] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in this specification indicates at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0013] The description of the method flow in the specification of this application and the steps in the flowcharts in the drawings of the specification of this application do not necessarily need to be strictly executed according to the step numbers. The method steps can be executed in a different order. In addition, some steps can be omitted, multiple steps can be combined into one step, and / or one step can be decomposed into multiple steps.

[0014] The following is a detailed description of the public security digital network service method, device, equipment and medium for public security digital objects provided by the embodiments of the present application in combination with the accompanying drawings and preferred embodiments.

[0015] In the field of public security digital objects, data interoperability has long faced the challenge of "information silos." Inconsistent data standards and formats across police departments, regions, and business systems hinder cross-regional and cross-departmental collaboration. Furthermore, data originates from multiple departments, posing significant challenges to its traceability and interpretability.

[0016] Based on this, this application provides a new data service method for public security digital objects that can effectively break the "information island", unify data representation, strengthen data association, improve data traceability and interpretability, and support complex relationship query and visual analysis.

[0017] See Figure 1 , the embodiment of the present application provides a public security digital object-oriented public security digital network service method, such as Figure 1 Shown, including: Step S1, obtaining public security data of the target system; encapsulating the public security data into a digital object consisting of an identifier, metadata, and a data entity; Step S2: storing the identifier in an identifier resolution system, storing the metadata in a relationship registry, and storing the data entity in a digital object repository; Step S3, constructing a knowledge graph and a graph database based on the digital objects; the knowledge graph uses the identifier as the graph entity name, the relationship between the digital objects as the graph relationship, and the metadata as the graph attribute; Step S4, in response to the interaction request, performing a multi-dimensional search based on the knowledge graph; Step S5: display the data objects and their relationship networks on a visual interactive page based on the knowledge graph.

[0018] Furthermore, the identifier is configured as an address ID of the data entity in the digital object repository, and the identifier can be located and resolved through the Digital Object Identity Resolution Protocol (DO-IRP).

[0019] Furthermore, the metadata includes a data type and attribute information corresponding to the type, wherein the data type includes at least one of the following: table, picture, video, device, model and service.

[0020] Furthermore, the data entity is the data itself.

[0021] In practice, public security data entities are complex, multi-source, and heterogeneous data within the public security sector. They encompass multiple police types, including public security, patrol, traffic, and population; multiple systems, including residential security systems, the "One Standard, Three Realities" system, and street patrol systems; and a wide variety of data types, including databases, images, videos, equipment, models, and services. Consequently, public security data has diverse sources, multiple formats, and difficulty in standardizing.

[0022] A digital object identifier (DOI) is a unique ID used to identify digital objects. By constructing a DIO, data representation can be decoupled from the data entity, creating a standardized and unified data representation method that shields data with different underlying standards and formats. This decoupling method also ensures that the data entity is no longer accessed during searches for basic data information, thereby ensuring data entity security. Furthermore, the DIO is the address ID of the data entity in the digital object repository. ID resolution ensures successful access to the data entity.

[0023] Different types of public security data have different metadata. The metadata of library table data includes the Chinese name of the table, the English name of the table, the table structure, the data volume, the last update time, the label and description; the metadata of image data includes the name, format, size, area code, label and description; the metadata of video data includes the name, format, size, area code, label and description; the metadata of device data includes the name, type, manufacturer, area code, storage time, device status, label and description; the metadata of model data includes the name, creation time, creator, label and description; the metadata of service data includes the name, type, label and description.

[0024] Graph entity names are named using identifiers rather than data names, making them more standardized and regulated. Graph entities can also be accurately located through identifier resolution. Graph relationships are constructed from relationships between digital objects, including association, extraction, application, and subordination (for example, videos and devices are subordinating). The graph attribute construction process involves passing the graph entity name as a parameter to the relationship registry. The relationship registry then searches based on the search parameters and the search interface, returning graph attribute information related to the search request.

[0025] See also Figure 2 When this application is implemented, the server includes an identity resolution system, a relationship registry, a digital object warehouse, a graph construction module, a data extraction and synchronization module, and a search and query service module.

[0026] The identification resolution system is used to maintain the unique identification (DOID) of public security digital objects and store the status information of digital objects; it supports the provision of identification resolution services to the outside world through the IRP protocol; the client can resolve the storage address, access method, permission information, etc. of the digital object through the DOID; and finally use the DOIP protocol to access and operate the digital object.

[0027] The relational registry is used to maintain metadata information of public security digital objects; it provides an interface for obtaining and operating metadata through the DOIP protocol; it also provides a digital object search interface based on metadata; it can realize the discovery and retrieval of digital objects without obtaining data entity permissions.

[0028] Digital Object Warehouse: used for secure, reliable and persistent storage of data entities of public security digital objects; data entities include but are not limited to: structured tables, images, videos, device information, models and services; storage formats are diversified, supporting local disks, cloud servers, databases and other formats; providing a unified data access interface based on the DOIP protocol.

[0029] All graph information is written to the Neo4j graph database, which serves as the underlying graph storage engine. In the data extraction and synchronization module, Flink is used to read data from the digital object warehouse in real time or batches. Data is parsed and cleaned according to the standard format of the identity resolution system. Metadata and entity relationships are dynamically extracted and converted into the required structure for the graph. The processed graph data is then written to the Neo4j graph database in real time.

[0030] The search and query service module works in conjunction with the identity resolution system and the graph database, returning results for aggregated display. The client provides a visual user interface to access system components based on standardized protocols and obtain the results of public security data access operations. Access operations include entity services, relationship services, search services, and graph visualization services. Entity services: support the addition, deletion, and modification of public security data entities. Relationship services: support the addition, deletion, and modification of semantic relationships between public security digital objects. Search services: support multi-dimensional retrieval based on graph entity names, graph relationships, or graph attributes; search results are linked to the identity resolution system and the graph database to ensure accurate positioning.

[0031] The search service corresponds to step S4. Further, in step S4, in response to the interaction request, a multi-dimensional search is performed based on the knowledge graph, including: Step S41: Search based on the graph entity name. This specifically includes: Step S411: obtaining search parameters based on the interaction request, and sending the search parameters to the identity resolution system and the graph database; Step S412: receiving a matching graph entity returned by the identity resolution system; Step S413: receiving attribute information associated with the graph database.

[0032] For example, in a specific implementation, the search keywords can be sent as search parameters to the identity resolution system and the graph database; the identity resolution system searches according to the search parameters and the search interface, and returns the graph entities related to the search request; the graph database searches according to the search parameters and the search interface, and returns the attribute information related to the search request.

[0033] Step S42: Search based on the graph relationship. Specifically, it includes: Step S421: selecting any graph entity as a reference entity based on the interaction request, and selecting a target entity relationship associated with the reference entity; Step S422, receiving the entity name with the associated graph returned based on the search of the graph database; Step S423: sending the associated entity name as a search parameter to the identity resolution system and the graph database; Step S424, receiving a matching graph entity returned by the identity resolution system; Step S425: Receive attribute information related to the graph database.

[0034] When this step is specifically implemented, a certain graph entity is selected as a reference entity; one or several entity relationships associated with the reference entity are selected; the graph entities having the selected entity relationships with the reference entity are searched in the graph database, and the names of the associated graph entities are returned; The associated entity name is sent as a search parameter to the identity resolution system and the graph database; the identity resolution system searches according to the search parameter and the search interface, and returns the graph entities related to the search request; the graph database searches according to the search parameter and the search interface, and returns the attribute information related to the search request.

[0035] Step S43: Search based on the graph attributes. Specifically, it includes: Step S431: obtaining search parameters based on the interaction request, and sending the search parameters to the graph database; Step S432, receiving the graph entity name and attributes returned based on the associated graph database; Step S433: sending the associated entity name as a search parameter to the identity resolution system; Step S434: receiving the matching graph entity returned by the identity resolution system.

[0036] When this step is implemented, the attribute keywords are sent to the graph database to obtain the matching entity names; the search keywords are sent to the graph database as search parameters; the graph database searches according to the search parameters and the search interface, and returns the graph entity names and attributes related to the search request; the graph entity names searched by the graph database are sent to the identity resolution system as search parameters; the identity resolution system searches according to the search parameters and the search interface, and returns the graph entities related to the search request.

[0037] In specific implementation, this application utilizes digital networking technology to encapsulate public security data into digital objects consisting of identifiers, metadata, and data entities, and stores these objects in an identifier resolution system, a relational registry, and a digital object repository. Therefore, operations such as searching, filtering, and expanding data entities require the use of standardized digital networking protocols, including the Digital Object Interface Protocol (DOIP) and the Digital Object Identifier Resolution Protocol (DO-IRP). DOIP regulates access to and manipulation of digital objects, while DO-IRP regulates access to and manipulation of digital object identifiers.

[0038] The graph visualization service corresponds to step S5. Furthermore, the visualization interaction page is further configured as follows: It supports displaying the knowledge graph composed of public security data objects, and can filter graph entities according to data type; in the page, you can set filtering conditions based on data type in the upper right corner. Data types include libraries, tables, pictures, videos, equipment, models and services. When you click on a data type, only graph entities with this data type will be retained on the page.

[0039] You can click on any map entity to view its detailed properties, and filter the map entities according to police type, region and business system. In the upper right corner of the page, you can set filtering conditions based on police type, region and business system. Among them, police types include public security, patrol, traffic, and population; regions include provinces, cities, counties, districts, and streets; business systems include community security systems, one standard and three real systems, street patrol systems, etc. When you click on a certain police type (region or business system), only map entities with this police type (region or business system) will be retained on the page.

[0040] It supports the "expand line" operation, that is, starting from a certain entity, dynamically displaying other entities and relationships associated with it; a certain graph entity can be expanded according to the entity relationship to display the associated graph entities; on the page, right-click on a graph entity and select one or several relationships to display the graph entities and connection relationships with such relationships on the page.

[0041] Graph entities can be searched and displayed based on their names and attribute contents. On the page, enter the name of the graph entity or attribute contents in the search box to search for the graph entity and display it on the page.

[0042] In addition, it also supports interactive functions such as map layout optimization, zooming, and highlighting. Based on the above settings, data objects and relationships can be more clearly visualized.

[0043] Based on the above technical solution, this application provides a public security digital network service method for public security digital objects. This method encapsulates public security data into digital objects consisting of identifiers, metadata, and data entities, and stores them in an identifier resolution system, a relationship registry, and a digital object repository, respectively. A knowledge graph is then constructed for the public security data objects, with identifiers serving as graph entities, relationships between digital objects serving as graph relationships, and metadata serving as attributes. Based on digital network technology, multi-source heterogeneous data can be identified according to a unified standard, and the identifiers used to name graph entities achieve a unified representation of graph entity names and a clear entity structure. Furthermore, the identifiers themselves record the address information where the data is stored, allowing the data to be traced through the identifiers. This method shields data with different underlying standards and formats, using identifiers as graph entity names instead, thereby ensuring the standardization and normalization of entity names. Data can be queried and searched based on the knowledge graph and digital network standardized protocols, allowing searches based on identifiers and attributes, as well as more complex fuzzy searches based on relationships between data objects. Furthermore, relationships between public security data objects can be visualized, enhancing the traceability and interpretability of public security data.
