Dynamic Mobile Lock Image Pattern for Public Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device unlocking systems expose user passwords in public, making them vulnerable to misuse, as they require users to input passwords visibly, which can be easily intercepted by others.
Innovation Solution
A dynamic unlocking system that displays varying lock images on a mobile device's touch screen, where at least one part of the image is altered, and the user must input a matching preset image to unlock the device, thereby obscuring the password from observers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a preset password is displayed on the touch screen for unlocking, then the user can easily input the password, but the password may be easily exposed to others in public places
Solution Approach 1:
The lock image is dynamically altered by changing the position of at least one image element between display and non-display states. This dynamic modification ensures the password pattern is not static and predictable, reducing exposure risk while maintaining user ability to input the correct pattern.
Solution Approach 2:
Only specific parts of the lock image (certain image elements) are altered in position while other elements remain stationary. This local modification approach maintains recognizability for the user while obscuring the complete pattern from observers, balancing ease of operation with security.
2Object-affected harmful factors
If the lock image is altered by changing position of image elements, then the password exposure is minimized, but the system complexity increases
Solution Approach 1:
The lock image is segmented into multiple independent image elements that can be individually positioned and controlled. This segmentation allows selective alteration of specific elements without redesigning the entire unlocking system, managing complexity through modular design.
Solution Approach 2:
The system changes the positional parameters of image elements within the lock image. By modifying only the position parameter of selected elements rather than the entire image structure, the system achieves password obscuration with minimal complexity increase.

AI summary
A system and a method for dynamically unlocking a mobile device are provided. The method includes displaying various lock images, where at least one of the parts is altered, when an attempt is made to unlock the mobile device, determining whether a lock image, detected according to a user input, matches a preset image, and unlocking the mobile device according to the result of matching between the detected lock image and the preset image. The system and method increases the level of security when an unlock attempt is made in a public place.
