Dynamic Unlocking Label Generation for Secure Screen Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock screen unlocking methods require users to preset a value, which lacks dynamic interaction and can be insecure, as the preset value must be actively changed to maintain security, but this process is not very effective in terms of user operability and security.
Innovation Solution
A method and apparatus that dynamically updates interactive information based on user operations, generating an unlocking label and interference labels, where the unlocking label is used to unlock the screen after being triggered by the user, while interference labels fail to unlock, enhancing security by constantly changing the unlocking label.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a preset value is used for unlocking, then the unlocking process is simple, but the security is poor because the preset value must be actively changed to maintain security
Solution Approach 1:
The patent applies dynamics by making the unlocking value change automatically over time rather than remaining static. The system dynamically generates new unlocking values at predetermined time intervals, transforming the static preset value into a dynamic, time-varying parameter that automatically updates without user intervention.
Solution Approach 2:
The system implements self-service by automatically changing the unlocking value without requiring active user participation. The terminal device autonomously generates and updates unlocking values based on time intervals, eliminating the need for users to manually change passwords while maintaining security.
2Reliability
If the preset value is changed actively to maintain security, then the security improves, but the user operability becomes less effective
Solution Approach 1:
The system performs the value-changing operation autonomously without requiring active user participation. The terminal device automatically generates new unlocking values at predetermined time intervals, eliminating the burden of manual password changes while maintaining security.
Solution Approach 2:
The unlocking value transitions from a static user-set parameter to a dynamic system-generated parameter that automatically evolves over time. This dynamic approach ensures security through continuous value changes while removing operational complexity from the user side.
3Object-affected harmful factors
If a stolen label is used, then unauthorized access can occur, but the patent prevents this by making stolen labels invalid
Solution Approach 1:
The system uses dynamic, time-varying unlocking values that automatically expire and regenerate. This temporal dimension of security ensures that even if a value is stolen, it becomes invalid after the predetermined time interval, preventing unauthorized access without requiring complex verification systems.
Solution Approach 2:
The system preemptively invalidates stolen unlocking values by implementing automatic expiration. Before a stolen value can be misused indefinitely, the system预先 (in advance) establishes a time limit that automatically renders the value obsolete, preventing potential harm from theft.

AI summary
A screen unlocking method and apparatus, and a computer device and a storage medium. The method comprises: obtaining interactive information generated when a user performs a predetermined operation; dynamically updating the generated interactive information to a pre-built interactive information database; upon receiving a screen unlocking request, invoking first interactive information in the database according to a first predetermined mode; generating an unlock tag according to said first interactive information; generating, according to the unlock tag, multiple interference tags that are different from the unlock tag; and sending the unlock tag and the multiple interference tags to a terminal device for display, receiving a user's operation for triggering the unlock tag, and unlocking a screen.
