Information Processing Apparatus Restricted History Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing apparatuses fail to maintain security while allowing the reuse of setting history information for new jobs, as they inadvertently disclose confidential information such as personal data when displaying setting screens.
Innovation Solution
An information processing apparatus with a controller that restricts the display of restricted information from setting history, ensuring that only authorized users can access sensitive data, maintaining security while allowing convenient reuse of setting history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If setting history information is displayed as it is for new jobs, then convenience of reuse is improved, but security is worsened due to disclosure of confidential information
Solution Approach 1:
The patent extracts and separates restricted information (such as personal information and confidential data) from the setting history information. When displaying the setting screen, the system removes or masks these restricted portions while preserving the remaining useful settings, thereby enabling convenient reuse without exposing sensitive data.
Solution Approach 2:
The patent applies different display qualities to different portions of the setting history information. Restricted information is masked or hidden, while non-restricted information is displayed normally. This local differentiation allows the system to maintain security for sensitive portions while preserving usability for public portions.
2Object-affected harmful factors
If restricted information is removed from display, then security is improved, but completeness of setting history is worsened
Solution Approach 1:
The system extracts only the restricted portions (personal information, confidential data) from the setting history while leaving the remaining useful settings intact. This selective extraction maintains the completeness of non-sensitive information while removing only what compromises security.
Solution Approach 2:
The patent introduces an intermediary mechanism (the controller) that mediates between the stored setting history and the display output. This intermediary selectively processes the information, removing restricted portions while preserving others, thus balancing security requirements with information completeness.
Data Source
AI summary
An information processing apparatus includes a storage and a controller. The storage stores history information pertaining to job execution, and when the history information is read from the storage and the history information includes restricted information, the controller restricts display of the restricted information.
