Solution Overview

Problem

Existing security protection methods for drawing files in enterprise networks suffer from low reliability and accuracy due to false or missing recognition, as they rely solely on drawing names that can be modified, affecting access security.

Innovation Solution

A security protection method that involves parsing drawing files to extract feature information, matching it with a target feature information set, and performing security management based on the matching result to ensure accurate identification and protection of protected drawing files.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If drawing names are used for security protection identification, then the method is simple to implement, but the reliability and accuracy are low due to false or missing recognition

Engineering Contradiction:

Improveease of implementationVSAvoidreliability of security protection

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces feature information extraction as an intermediary mechanism between the drawing file and security protection identification. Instead of directly using drawing names, the system extracts feature information from drawing content and uses this intermediate representation for accurate identification, thereby resolving the contradiction between implementation simplicity and identification reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/simple approach of using drawing names with an automated feature extraction system that analyzes drawing content semantically. This substitution of the identification mechanism from surface-level name matching to deep-content feature analysis significantly improves reliability while maintaining ease of use through automation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If drawing names are used for security protection identification, then the system complexity is low, but the accuracy of protected drawing identification is insufficient

Engineering Contradiction:

Improvesystem complexityVSAvoidaccuracy of drawing identification

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the drawing file analysis into multiple independent feature extraction components, each analyzing specific aspects of the drawing content. This segmentation allows the system to achieve high identification accuracy through multiple analysis dimensions while keeping each individual component relatively simple, thus resolving the contradiction between system complexity and identification accuracy

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from one-dimensional name-based identification to multi-dimensional feature-based identification by extracting features from different aspects of drawing content (such as geometric properties, semantic information, structural characteristics). This dimensional expansion enables accurate identification without proportionally increasing system complexity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If feature extraction and matching is performed on drawing files, then the reliability and accuracy of security protection is improved, but the processing time and computational resources increase

Engineering Contradiction:

Improvereliability of security protectionVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs feature extraction and creates feature information databases in advance for protected drawing files. This preliminary action allows the system to store pre-extracted features and only perform matching operations when new drawings need to be identified, significantly reducing processing time during actual security checks while maintaining high reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism where the feature extraction and matching results are used to update the security protection status. The system learns from previous identifications and adjusts its feature extraction priorities, thereby reducing unnecessary processing time while maintaining high accuracy through iterative improvement

Inventive Principle:

Principle #23Feedback

AI summary

The present disclosure relates to the technical field of data security, and discloses a security protection method for a drawing file, an apparatus, a device, a medium, and a program product. The security protection method for a drawing file comprises: acquiring a first drawing file; acquiring a matching result of matching first feature information corresponding to the first drawing file with each second feature information in a target feature information set, where the first feature information is obtained by parsing the first drawing file to obtain description information of a target element in the first drawing file, and performing feature extraction on the obtained description information of the target element, and the target feature information set includes second feature information of at least one protected drawing file; and performing security protection management on the first drawing file based on the matching result.
