Display Menu Tab Locking to Avoid Repeated Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunction peripherals (MFPs) face operability issues due to repeated authentication when switching between tabs, impairing user experience.
Innovation Solution
Implement a lock control system that sets menu screens to a locked state based on user settings, allowing tabs to be unlocked with a password or authentication, and maintains the unlocked state during tab transitions, reducing the need for repeated authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is required for each tab access to ensure security, then security is improved, but operability deteriorates due to repeated authentication when switching between tabs
Solution Approach 1:
The system performs preliminary authentication when a user first accesses a protected tab, storing the authentication result. When the user switches to another tab and returns to the previously authenticated tab, the system retrieves the stored authentication result and automatically re-opens the tab without requiring re-authentication, thus resolving the contradiction between security and operability
Solution Approach 2:
The system creates a copy of the authentication state for each tab, storing whether authentication has been performed. This allows the system to restore the authentication state when switching between tabs, maintaining security while improving operability by avoiding repeated authentication
2Reliability
If authentication state is reset when switching tabs to maintain security, then security is improved, but productivity deteriorates due to time loss from repeated authentication
Solution Approach 1:
The system maintains the authentication state continuously across tab switches by storing the authentication result and retrieving it when needed. This ensures that the useful action of authentication is not repeatedly performed, improving productivity while maintaining security through state persistence
3Reliability
If all tabs are locked to ensure security, then security is improved, but ease of operation deteriorates due to increased complexity of authentication management
Solution Approach 1:
The system applies different lock states to different tabs individually rather than uniformly locking all tabs. Each tab can have its own authentication requirement setting, allowing users to access frequently used tabs without authentication while maintaining security on sensitive tabs, thus resolving the contradiction between security and ease of operation

AI summary
A control apparatus includes a lock control unit configured to set a menu screen corresponding to at least one tab among a plurality of menu screens respectively corresponding to a plurality of tabs to a locked state in which the menu screen is not displayed, and a setting unit configured to set information for releasing the locked state for each of the menu screens respectively corresponding to the plurality of tabs, wherein the lock control unit sets the menu screen corresponding to a target tab in the unlocked state to the locked state based on the setting unit setting or changing the information for releasing the locked state of the target tab in the unlocked state in which the locked state is released and the menu screen is displayed.
