Biometric Authentication Window Placement for Variable Sensor Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems face challenges in accurately determining the location of authentication components due to diverse hardware deployments in terminals, leading to failed biometric authentication.
Innovation Solution
An authentication window display method that determines the display location of an authentication window based on the location of an authentication component corresponding to the authentication mode, allowing the user to accurately locate the component for successful biometric authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the third-party application determines the display location of the authentication window independently, then the application has flexibility in designing its authentication interface, but the authentication window location may conflict with the actual location of the authentication component (e.g., fingerprint sensor) on the terminal
Solution Approach 1:
The system introduces an intermediary mechanism where the terminal determines the authentication window display location based on the actual authentication component location, and provides prompt information to guide the user. This intermediary coordination between the application layer and hardware layer resolves the conflict between interface flexibility and authentication reliability.
2Device complexity
If the authentication window is displayed at a fixed location determined by the application, then the interface design is simple, but it cannot adapt to different hardware deployments (e.g., bezel-less phones with fingerprint sensors at different locations)
Solution Approach 1:
The authentication window display location is made dynamic rather than fixed. The terminal dynamically determines the display location based on the actual authentication component location, allowing the interface to adapt to different hardware deployments while maintaining simple design principles.
Solution Approach 2:
The system changes the parameter of display location from a fixed value to a dynamic value that depends on the authentication component's physical location. This parameter change enables the interface to adapt to various hardware configurations including bezel-less phones with different sensor placements.
3Device complexity
If the user is not provided with clear location guidance for the authentication component, then the interface design is minimal, but the user cannot accurately locate the authentication component leading to authentication failure
Solution Approach 1:
The system provides self-service guidance by automatically generating and displaying prompt information that tells the user where to perform authentication. This self-service approach improves ease of operation without significantly increasing interface complexity, as the prompt information is generated and managed automatically by the system.

AI summary
An authentication window display method includes, after an authentication request sent by a third-party application is detected, obtaining authentication information from the third-party application, where the authentication information includes an authentication mode and first prompt information. The authentication window display method further includes determining a display location of a first authentication window based on a location of an authentication component corresponding to the authentication mode and the authentication mode, where the authentication component is configured to collect biological information of a user. The authentication window display method further includes displaying the first authentication window at the display location, where the first authentication window displays the first prompt information.
