Dynamic Access Control for MFP Device Lifespan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunction peripherals (MFPs) cannot effectively restrict abnormal access to devices due to environmental changes such as version updates or setting changes, leading to potential device wear and reduced lifespan.
Innovation Solution
An information processing apparatus that controls access to devices based on access restriction information, acquires diagnostic information, detects abnormal access, and modifies the access restrictions to prohibit access from the offending process, thereby extending device life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access restriction information is acquired from an external server and used to control access, then access control is implemented, but abnormal access due to environmental changes cannot be restricted
Solution Approach 1:
The system implements a feedback mechanism where diagnostic information is continuously acquired from devices, abnormal access is detected based on this information, and access restriction information is dynamically modified in response to detected abnormalities. This closed-loop feedback enables the system to adapt to environmental changes and restrict abnormal access effectively.
Solution Approach 2:
The access restriction information is transformed from a static configuration to a dynamic parameter that can be automatically modified based on detected abnormal access patterns. The system dynamically adjusts access restrictions by modifying the access restriction information storage based on diagnostic data and detected abnormalities, enabling adaptive response to changing environments.
2Device complexity
If static access restriction information is used, then access control is simple to implement, but device lifespan is reduced due to unrestricted abnormal access
Solution Approach 1:
The system uses feedback from diagnostic information to automatically detect abnormal access and modify access restrictions accordingly. This feedback-driven approach extends device lifespan by preventing abnormal access without requiring complex manual configuration or intervention.
Solution Approach 2:
The system performs self-monitoring and self-protection by automatically acquiring diagnostic information, detecting abnormal access patterns, and modifying access restrictions without external intervention. This self-service capability protects device lifespan while maintaining relatively simple system architecture.
3Reliability
If access restriction information is dynamically modified, then abnormal access is restricted effectively, but system complexity increases
Solution Approach 1:
The system implements feedback-based automatic modification of access restrictions, where diagnostic information triggers detection of abnormal access, which then automatically modifies access restriction information. This feedback mechanism achieves effective abnormal access restriction through a relatively simple automated process rather than complex manual control systems.
