Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for automatically loading parameters are prone to errors, require complex operations, and may leak confidential information, especially in environments without external networks or camera lenses, and are costly and resource-intensive.
Innovation Solution
A method and system that encrypts and encodes information using reversible information hiding techniques, allowing parameters to be automatically loaded into fields by decoding and decrypting hidden data within engineering drawings, ensuring secure and efficient parameter loading without additional device installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If barcode scanning is used to automatically load information, then manual input errors are reduced, but additional devices (barcode scanners or camera lenses) and network connection are required
Solution Approach 1:
The patent embeds parameter information as hidden data within existing engineering drawing images, creating a self-contained copy of the information that does not require external scanning devices. The information is copied into the image file itself through encoding techniques, allowing direct extraction without additional hardware
Solution Approach 2:
The patent extracts parameter information from the engineering drawing images and loads it directly into the software system. By taking out the information embedding step and integrating it into the existing software architecture, the system eliminates the need for separate barcode scanning devices while maintaining automatic information loading capability
2Productivity
If configuration files are installed to automatically load parameters, then manual input is eliminated, but operation becomes complicated and confidential information may leak
Solution Approach 1:
The patent merges the parameter information with the engineering drawing images themselves. Instead of separate configuration files, the parameters are combined into the image data structure, allowing users to load a single file that contains both the drawing and the embedded parameters, simplifying the operation while maintaining efficiency
Solution Approach 2:
The patent changes the state of parameter information from plain text in configuration files to encoded hidden data within images. This parameter transformation enables secure information transmission while maintaining automatic loading capability, as the encoded parameters can be extracted and decrypted without user intervention
3Extent of automation
If image recognition is used to extract parameters, then automatic information loading is achieved, but errors in distinction occur and huge operational resources are consumed
Solution Approach 1:
The patent applies preliminary encoding to embed parameters directly into the engineering drawing images before they are used. This preliminary action of information embedding eliminates the need for complex image recognition and parameter extraction processes, ensuring 100% accuracy since the information is already in the desired format within the image
Data Source
AI summary
A method and a system for automatically loading parameters, and a client-end server thereof are provided, and the method and the system, by a reversible information hiding technology, entrain various required parameters in an engineering drawing hiddenly to generate an encrypted file; and then, after decrypting the encrypted file by a pre-stored cipher key, obtain and automatically load the required parameters. Therefore, the parameters can be automatically loaded quickly, accurately and safely.
