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

VSEngineering 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

Engineering Contradiction:
ImprovesecurityVSAvoidunlocking convenience
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #16Partial or excessive action

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

Engineering Contradiction:
Improveaccess convenienceVSAvoidprivacy protection
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #3Local quality

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.
