Mobile Terminal Lock Screen Icon Segmentation for Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals face challenges in providing convenient and secure unlocking mechanisms, as users often find it difficult to unlock their devices quickly while maintaining privacy and preventing unauthorized access.
Innovation Solution
A method and system for a mobile terminal that displays both restricted and non-restricted use icons on a lock screen, allowing users to select non-restricted icons for direct unlocking or perform authentication when selecting restricted icons, thereby streamlining the unlocking process while ensuring security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock function is applied to prevent unauthorized access and protect privacy, then security is improved, but user convenience for unlocking is worsened
Solution Approach 1:
The menu icons are segmented into two categories: restricted use icons (requiring authentication) and non-restricted use icons (allowing direct access). This segmentation allows the system to provide different levels of access control, enabling quick unlocking through non-restricted icons while maintaining security for restricted functions through authentication requirements.
Solution Approach 2:
The system allows partial access without full authentication by enabling non-restricted use icons to be activated directly on the lock screen. This partial action approach provides sufficient convenience for common operations while reserving full authentication for sensitive operations, balancing security and usability.
2Ease of operation
If all menu icons are accessible without authentication on lock screen, then user convenience is improved, but security and privacy protection are worsened
Solution Approach 1:
Different quality levels of access control are applied to different menu icons based on their sensitivity. Non-restricted use icons allow direct access from the lock screen for convenience, while restricted use icons require authentication. This local differentiation of access control quality enables both convenience and security to coexist.

AI summary
A method of controlling a mobile terminal by displaying simultaneously a plurality of menu icons comprising at least one restricted use icon and at least one non-restricted use icon; performing a user authentication procedure responsive to user selection of the at least one restricted use icon; and unlocking the mobile terminal responsive to user selection of the at least one non-restricted use icon or responsive to completion of the user authentication procedure.
