Image Processing Apparatus Defect Verification Data Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in reproducing errors for maintenance purposes without leaking confidential information, as existing solutions fail to prevent leakage of confidential information and accurately reproduce errors related to character font data.
Innovation Solution
An information processing apparatus and method that detects defects during image processing, produces verification data by modifying process data to replicate the defect, and externally outputs this verification data instead of the original data, ensuring confidential information is not leaked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the original process data is externally output for error reproduction, then the error can be accurately reproduced, but confidential information leaks
Solution Approach 1:
The patent creates verification data that is a copy of the original process data but with confidential information replaced by dummy data. This copy maintains the structural and functional characteristics needed for error reproduction while eliminating sensitive content. The verification data serves as a substitute that preserves diagnostic value without exposing confidential information.
Solution Approach 2:
The patent extracts and removes confidential information from the process data by replacing it with dummy data. The extraction process identifies and separates sensitive elements (such as character font data) from the overall data structure, allowing the remaining verification data to be safely output for external analysis while the confidential portion is discarded or retained internally.
2Object-affected harmful factors
If character data is replaced with random character codes, then confidential information in characters is protected, but errors related to character font data cannot be reproduced
Solution Approach 1:
Instead of replacing character data with random character codes that change the semantic meaning, the patent changes the parameter representation by using dummy data that preserves the structural and functional characteristics of the original data. The dummy data maintains the same data type, format, and relational properties, allowing error reproduction while protecting confidential information.
3Object-affected harmful factors
If verification data with dummy data is output, then confidential information is protected, but the data structure must be carefully maintained
Solution Approach 1:
The patent performs preliminary processing of the process data by pre-replacing confidential information with dummy data before external output. This preliminary action prepares the verification data in advance, ensuring that the data structure is already adapted for safe external transmission while maintaining all necessary functional characteristics for error diagnosis.
Data Source
AI summary
An information processing apparatus includes a hardware processor that: detects a defect that occurs when an image processor performs an image process on process data; produces verification data when the defect is detected during the image process, wherein the verification data is formed in a case that at least one portion of the process data, to be processed by the image processor, is changed and causes a same defect that occurs during the image process on the process data; and externally outputs the verification data instead of the process data.
