Description

Technical Field

[0001] This invention relates to the field of archival management technology, specifically to a system and method for cross-archive data collection within the same city. Background Technology

[0002] The current data management in archives has the following shortcomings:

[0003] (1) Data silo problem: Data in each branch is stored independently, and cross-branch collaboration requires manual export and import, which is inefficient;

[0004] (2) High data security risks: Plaintext transmission or simple encryption can easily lead to the leakage of archive information;

[0005] (3) Lack of a unified management platform: The data standards of each library are not uniform, and the cross-library search and access process is complicated, making it difficult to meet the needs of government collaboration.

[0006] The low efficiency, inadequate security, and decentralized management of cross-archive data transmission are technical problems that need to be addressed. Summary of the Invention

[0007] The technical objective of this invention is to address the above-mentioned shortcomings by providing a system and method for cross-library data transmission within the same city, thereby resolving the technical problems of low efficiency, insufficient security, and decentralized management of cross-library data transmission.

[0008] In a first aspect, the present invention provides a cross-library data system for archives within the same city, comprising a data acquisition module, an encrypted transmission module, a cross-library management module, an access control module, and a data storage module;

[0009] The data acquisition module is used to perform format conversion and metadata annotation on archive data to generate structured data that conforms to national standards.

[0010] The encrypted transmission module is used to build a dedicated data transmission channel based on SSL and AES-256 algorithms;

[0011] The cross-library management module is used to build a cross-library data catalog index, provide approval for cross-library data business processes, and store cross-library data operation records on the blockchain.

[0012] The access control module is used to provide access management for different archive users;

[0015] Preferably, the cross-library management module includes a data catalog service module, a process engine, and a blockchain evidence storage module;

[0016] The data catalog service module is used to establish a unified data classification standard and generate a cross-library data catalog index based on the data classification standard.

[0017] The process engine is used to provide approval for cross-library data business processes, which include querying, accessing, and copying. The approval content includes the application, review, authorization, and transmission loop of the business process.

[0018] The blockchain evidence storage module is used to store data operations on archive data using blockchain.

[0019] Preferably, the access control module is used to assign multi-level permissions to different archive users based on an access control model, and to provide access management based on a data certificate authentication mechanism. The multi-level permissions include query rights, download rights, and modification rights.

[0020] Secondly, the present invention provides a method for managing archive data across different locations within the same city, based on an archive data management system for cross-city operations as described in any of the first aspects, comprising the following steps:

[0024] Access control: Provides access management for users of different archives;

[0025] Data storage: Distributed storage enables redundant backup of active-active data within the same city.

[0026] As a preferred approach, during data collection, paper archives are collected using OCR recognition and metadata extraction methods, and the collected archive data is standardized into structured data that can be circulated across systems.

[0027] As a preferred option, the cross-library management model includes the following operations:

[0028] Data catalog service: Establish a unified data classification standard and generate a cross-library data catalog index based on the data classification standard;

[0029] Workflow Engine: Provides approval for cross-library data business processes, including querying, accessing, and copying. Approval content includes the application, review, authorization, and transmission loop of the business process.

[0030] Blockchain-based evidence storage: Data operations on archive data are stored on the blockchain.

[0031] As a preferred option, the access control module uses an access control model based on access to assign multi-level permissions to different archive users and provides permission management based on a data certificate authentication mechanism. The multi-level permissions include query rights, download rights, and modification rights.

[0032] The intra-city cross-library data system and method of the present invention have the following advantages:

[0033] 1. Efficiency Improvement: Through automated processes and standardized data interfaces, the time for cross-venue data exchange has been reduced from 24 hours of traditional manual processing to minutes;

However, the embodiments are not intended to limit the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0040] This invention provides a system and method for cross-library data transmission within the same city, which addresses the technical problems of low efficiency, insufficient security, and decentralized management of cross-library data transmission.

[0041] Example 1:

[0042] This invention discloses a cross-library data system for archives within the same city, comprising a data acquisition module, an encrypted transmission module, a cross-library management module, an access control module, and a data storage module.

[0043] The data acquisition module is used to convert the format of archive data and annotate metadata to generate structured data that conforms to national standards.

[0044] In this embodiment, the data acquisition module is deployed locally in each archive and is used to collect archive data from paper archives based on OCR recognition methods and metadata extraction methods, and to standardize the collected archive data into structured data that can be circulated across systems.

[0045] The encrypted transmission module is used to build a dedicated data transmission channel based on SSL and AES-256 algorithms.

[0046] In this embodiment, the encrypted transmission module is based on the Secure Sockets Layer (SSL) protocol and the AES-256 encryption algorithm to build a dedicated data transmission channel, ensuring that data transmission across venues is protected against tampering and theft.

[0047] The cross-library management module is used to build a cross-library data catalog index, provide approval for cross-library data business processes, and store cross-library data operation records on the blockchain.

[0048] In this embodiment, the cross-library management module includes a data catalog service module, a process engine, and a blockchain evidence storage module. The data catalog service module is used to establish unified data classification standards (such as document, scientific and technological, and specialized archive categories) and generate a cross-library data catalog index based on the data classification standards. The process engine is used to provide approval for cross-library data business processes, which include querying, accessing, and copying. The approval content includes the application, review, authorization, and transmission loop of the business process. The blockchain evidence storage module is used to store data operations of the archives data on the blockchain.

[0049] The access control module is used to provide access management for users of different archives.

[0050] In this embodiment, the access control module is used to assign multi-level permissions to different archive users based on the access control model, and to provide access management based on the data certificate authentication mechanism. The multi-level permissions include query rights, download rights, and modification rights to prevent unauthorized access.

[0051] The data storage module is used to achieve redundant backup of active-active data within the same city through distributed storage.

[0052] In this embodiment, the data storage module adopts a distributed storage architecture, and achieves data redundancy backup through a dual-active data center in the same city to ensure data availability and disaster recovery capabilities.

[0053] Based on the system in this embodiment, the management process for cross-library visits within the same city is as follows:

[0054] (1) Data standardization processing: Each archive converts the format of the archives and marks the metadata (such as archive number, creation time, and security classification) through the data acquisition layer to generate archive data units that conform to national standards;

[0055] (2) Cross-library transfer application: Users submit data access applications through the cross-library management platform. The system automatically verifies the applicant's permissions and triggers the process engine to generate approval tasks (such as the initial review by the local library administrator → the final review by the target library administrator).

[0056] (3) Encrypted transmission and reception: After approval, the target hall's data acquisition layer encrypts the application data with AES-256 and transmits it to the applicant hall through an SSL channel; the applicant hall automatically decrypts and archives the data upon receipt.

[0057] (4) Operation traceability and auditing: The blockchain evidence storage module records data transmission and access behavior in real time and generates an unalterable audit log for regulatory authorities to verify.

[0058] Example 2:

[0059] This invention discloses a method for managing archive data across different locations within the same city. Based on the system disclosed in the embodiments, it realizes the management of archive data across different locations within the same city, including data collection, encrypted transmission, cross-management, access control, and data storage.

[0062] Step S200 Encrypted transmission: Construct a dedicated data transmission channel based on SSL and AES-256 algorithms.

[0063] In this embodiment, during encrypted transmission, a dedicated data transmission channel is constructed based on the Secure Sockets Layer (SSL) protocol and the AES-256 encryption algorithm to ensure that data transmission across venues is protected against tampering and theft.

[0064] Step S300 Cross-library Management: Construct a cross-library data catalog index, provide approval for cross-library data business processes, and store cross-library data operation records on the blockchain.

[0065] In this embodiment, cross-library management includes data catalog services, process engine services, and blockchain notarization. For data catalog services, a unified data classification standard (such as document, scientific, and specialized archive categories) is established, and a cross-library data catalog index is generated based on this standard. The process engine service provides approval for cross-library data business processes, including querying, accessing, and copying. Approval content includes the application, review, authorization, and closed-loop transmission of the business process. For blockchain notarization, data operations on archive data are notarized using blockchain.

[0066] Step S400 Access Control: Provide access management for users of different archives.

[0067] In this embodiment, the access control module assigns multi-level permissions to different archive users based on the access control model, and provides permission management based on the data certificate authentication mechanism. The multi-level permissions include query rights, download rights, and modification rights to prevent unauthorized access.

[0068] Step S500 Data storage: Achieve redundant backup of active-active data within the same city through distributed storage.

[0069] In this embodiment, a distributed storage architecture is adopted for data storage, and data redundancy backup is achieved through dual active data centers in the same city to ensure data availability and disaster recovery capabilities.
