Biometric Authentication Display Using Avatars for Private Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric authentication systems in electronic devices face security risks due to potential leakage of unique biometric information, such as iris or face data, and users may be reluctant to expose their body parts in public places.
Innovation Solution
An electronic device converts captured images of users into objects, such as emojis or characters, and displays these objects on the screen, guiding users to adjust their posture for accurate biometric recognition without exposing sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the captured image is displayed on the display for biometric authentication, then the user can identify the captured image and reposition the body part to obtain biometric information, but there is a chance of leakage of biometric information and users may be reluctant to expose their body part in public places
Solution Approach 1:
The patent uses a camera to capture an image of the user's body part and displays this image on the screen instead of displaying raw biometric data. The captured image serves as a visual copy that guides the user to position their body part correctly while preventing direct exposure of sensitive biometric information. This resolves the contradiction by providing ease of operation through visual feedback while mitigating the harm of biometric information leakage.
2Loss of information
If the captured image is displayed on the display, then guidance for positioning is provided, but biometric information may be exposed to hacking programs or public view
Solution Approach 1:
The system creates a visual copy of the body part through camera capture and displays it for positioning guidance. This copy contains the necessary spatial and positional information needed for proper alignment, while the actual biometric data remains secure in the sensor module. The copying principle allows the system to provide comprehensive positioning information without compromising security.
Solution Approach 2:
The patent separates the functions of visual guidance and biometric data collection into distinct components. The camera module captures images for display purposes only, while the sensor module independently collects biometric information. This segmentation ensures that the information displayed for guidance does not contain sensitive biometric data, thereby maintaining security while providing necessary positioning feedback.

AI summary
According to an embodiment, an electronic device comprises a camera module including a camera, a sensor module including sensing circuitry, a display, a memory; and a processor configured to: control the memory to store registered biometric information, obtain at least one image using the camera module, obtain biometric information using the sensor module, control the display to display a first object generated by converting at least part of a second object included in the at least one image, and control the display to display the first object together with information for changing posture based on at least one of a position, shape, or size of a third object included in the at least one image until the obtained biometric information and the registered biometric information meet a designated condition.
