Network Document Protection System for Business Secret Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security technologies allow operators to set document security levels subjectively, leading to potential leaks of confidential information, and fail to track the originality and distribution of documents accurately due to frequent hash generation and digital signature updates.
Innovation Solution
A network-based document protection system that includes a template module for searching and executing templates/documents, an authentication module for generating and recognizing operator identification codes, and a security module for secure storage and processing, ensuring objective security level setting and document tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an operator directly sets the security level of a document according to a designated rule, then the operator can quickly assign security levels, but the security level setting becomes subjective and may lead to incorrect classification or malicious leakage
Solution Approach 1:
The document management system automatically determines security levels by analyzing document content, metadata, and classification rules without requiring manual operator intervention. The system self-evaluates documents against predefined criteria and assigns appropriate security levels, eliminating subjective human judgment while maintaining high productivity through automated batch processing.
Solution Approach 2:
The system implements a feedback mechanism where document security levels are continuously evaluated and adjusted based on access patterns, user roles, and organizational policies. The security level setting is not static but dynamically updated based on feedback from system monitoring and policy changes, ensuring both accuracy and adaptability.
2Reliability
If a hash is generated for each document operation (loading, digital signature), then document integrity can be verified at each step, but the original hash is lost and document distribution tracking becomes impossible
Solution Approach 1:
The system generates and stores the original hash of a document immediately when the document is first created or imported into the system. This original hash is preserved in a secure repository and serves as the baseline for all future integrity verifications. Subsequent hash generations during operations do not replace but supplement the stored original hash, enabling both integrity verification and distribution tracking.
Solution Approach 2:
Instead of replacing the original hash with new hashes during operations, the system creates copies of hash values at each operation step while preserving the original. Each operation generates a new hash that is stored as a historical record linked to the original document, forming a hash chain that enables追溯 (tracing) of document distribution and modifications without losing the original reference point.
3Reliability
If conventional security technology updates document hash and digital signature every time, then document security can be maintained, but it becomes impossible to track the distribution process and prove document originality
Solution Approach 1:
The system segments the document security and tracking functions into distinct modular components. The hash generation and verification process is separated from the document management workflow, with each operation step independently recorded. This segmentation allows the system to maintain security through regular hash updates while simultaneously enabling distribution tracking by organizing hash records in a structured, queryable format that distinguishes between security verification and provenance tracking.

AI summary
A network-based document protection system for the protection of business secret includes: a template module configured to search for the template information of a template stored in a template database (DB) or the document information of a document stored in a document DB, and to execute the corresponding template or document via a dedicated application; an authentication module configured to generate the document information by including the identification code of an operator in the corresponding template information or to identify a corresponding operator by recognizing an identification code from the document information of the executed document, according to the execution procedure of the template module; and a security module configured to store the document, generated or updated via the dedicated application, in the document DB, and to perform security processing on the document.
