Terminal Unlock Method Detecting Unauthorized User Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unlocking methods for electronic devices do not provide adequate security measures when unauthorized users attempt to access the device, as they only indicate incorrect input without alerting the owner to potential unauthorized access.
Innovation Solution
A method and device that determine whether the user belongs to a preset user group, and if not, acquire and store information about the unauthorized user, such as through biometric data, to notify the owner upon successful unlocking by the authorized user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional unlocking methods (numeric password, fingerprint recognition, etc.) are used, then the terminal can be protected from unauthorized use, but the owner cannot detect when unauthorized users attempt to unlock the terminal
Solution Approach 1:
The system implements feedback by recording unauthorized unlocking attempts and notifying the owner through messages or calls. When an unauthorized user attempts to unlock the terminal, the system detects this attempt, stores the information, and subsequently notifies the owner, creating a feedback loop that informs the owner of security events that would otherwise go undetected.
2Reliability
If the terminal provides detailed information about unauthorized users, then security monitoring is improved, but the complexity of the unlocking system increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring user groups (authorized and unauthorized) and establishing notification preferences before security incidents occur. The terminal is pre-programmed with logic to detect unauthorized attempts, record relevant information, and automatically notify owners based on predetermined settings, reducing the need for complex real-time decision-making during actual security events.

AI summary
An unlock processing method for a terminal, includes: receiving an input unlocking instruction from a user; determining whether the user belongs to a preset user group according to the unlocking instruction; and acquiring and storing information regarding the user, if it is determined that the user does not belong to the preset user group.
