Terminal Unlocking Masking Layer Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal unlocking methods are insecure due to their intuitive nature, making them vulnerable to unauthorized access and data theft.
Innovation Solution
A method and device that display a masking layer on the terminal screen when a start instruction is received, allowing an unlocking instruction to be input based on this layer, and only starting the application if the instruction matches a preset condition, enhancing concealment and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional unlocking methods (password, graphic swiping, fingerprint, voiceprint) are used, then the unlocking process is convenient and straightforward, but the concealment is weak and the security is insufficient
Solution Approach 1:
The patent introduces a masking layer as an intermediary between the user and the unlocking interface. This masking layer obscures the unlocking interface from view, preventing unauthorized observation while still allowing the legitimate user to interact with it. The masking layer acts as a mediator that preserves security without compromising the convenience of the unlocking process for authorized users.
Solution Approach 2:
The patent employs visual masking techniques where the masking layer changes the appearance or transparency of the screen regions. By controlling the visibility characteristics of different screen areas, the system conceals the unlocking interface from prying eyes while maintaining full functionality for the authorized user, thus improving security without affecting ease of operation.
2Ease of operation
If the unlocking interface is displayed intuitively on the screen, then the user can easily access the application, but the illegal holder can also easily observe and crack the unlocking method
Solution Approach 1:
The patent divides the screen into multiple regions with different visibility characteristics. The masking layer segments the display area such that the unlocking interface is hidden from external observation while remaining accessible to the user through touch or other input methods. This segmentation allows the system to maintain ease of application access while protecting against unauthorized observation and cracking attempts.
Solution Approach 2:
The masking layer serves as an intermediary element that sits between the unlocking interface and the external environment. It selectively blocks visual access to the unlocking interface for unauthorized users while allowing the legitimate user to interact with it, thus reducing vulnerability to unauthorized access without impacting the ease of access for authorized users.
3Reliability
If a masking layer is displayed on the screen to conceal the unlocking interface, then the security and concealment are improved, but the device complexity increases
Solution Approach 1:
The masking layer is implemented as a software-based solution that can be applied across different applications and unlocking methods without requiring hardware modifications. This universal approach allows the system to improve security through a single multi-functional component that works with various unlocking mechanisms (password, graphic, fingerprint, voiceprint), thereby limiting the increase in device complexity.
Solution Approach 2:
The masking layer uses software rendering to create a visual overlay that mimics physical masking without requiring additional physical components. By using digital copying and display manipulation techniques, the system achieves the security benefits of physical masking while avoiding the complexity of hardware modifications, thus improving security with minimal impact on device complexity.
Data Source
AI summary
A method that includes displaying a masking image layer on a terminal screen when receiving a start instruction used to start an application; receiving an unlocking instruction input based on the masking layer; if the unlocking instruction matches a preset instruction, starting the application. The present disclosure solves the technical problem in the conventional techniques of relatively low terminal unlock method security.
