Biometric Authentication Using Dynamic Object Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric authentication methods face reliability and efficiency issues due to the use of uniform authentication areas, which can be affected by external environments and the placement of objects during authentication.
Innovation Solution
An electronic device equipped with a camera and display, utilizing a processor to obtain images of external objects, display specific images on a specified area, and perform biometric authentication using corresponding biometric information, while withholding authentication if the object is not within the specified area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a uniform authentication area is used for biometric authentication, then the authentication process is simple to implement, but the reliability and efficiency of authentication are degraded
Solution Approach 1:
The patent applies local quality by dividing the authentication area into multiple zones with different functions. The preview area displays a portion of the captured image to guide object placement, while the authentication area performs the actual biometric verification. This localized differentiation improves authentication reliability without significantly complicating the overall system implementation.
Solution Approach 2:
The patent segments the authentication interface into distinct functional regions: a preview area that shows a portion of the captured image for user guidance, and an authentication area that performs the actual biometric verification. This segmentation allows the system to provide visual feedback while maintaining authentication accuracy, resolving the contradiction between simplicity and reliability.
2Device complexity
If a uniform authentication area is used for biometric authentication, then the system structure remains simple, but the authentication efficiency is reduced
Solution Approach 1:
The patent implements preliminary action by displaying a preview image in the preview area before authentication occurs. This preview shows the captured object's position and orientation, allowing users to adjust the object placement in advance. This preliminary visual feedback accelerates the authentication process by reducing failed attempts, while the segmented area structure keeps the system relatively simple.
