Biometric Authentication Virtual Object Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric authentication systems face security issues due to the potential leakage of unique iris or face information when displaying captured images on electronic devices, and users are hesitant to expose their body parts in public places.
Innovation Solution
An electronic device with a camera module, sensor module, and display that converts captured images into objects and guides users to adjust their posture until the biometric information matches the registered data, ensuring secure authentication without exposing sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device displays the captured image on the display for biometric authentication, then the user can position the body part correctly for obtaining biometric information, but there is a risk of leakage of biometric information such as iris or face information
Solution Approach 1:
The patent creates a virtual copy (virtual character) of the user's body part from the captured image and displays this copy instead of the actual biometric image. The virtual character is generated by processing the captured image through a virtual character generation module, which transforms real biometric data into a stylized representation that maintains authentication functionality while preventing direct exposure of sensitive information.
Solution Approach 2:
The patent introduces a virtual character as an intermediary between the captured biometric image and the display. This virtual character serves as a mediator that conveys positional guidance information to the user without directly exposing the original biometric data. The virtual character generation module acts as an intermediary processing layer that transforms and protects the information before presentation.
2Loss of information
If the electronic device displays the captured image showing the user's body part, then authentication guidance can be provided, but users are reluctant to allow their body part to be exposed in a public place
Solution Approach 1:
The system generates a virtual copy of the user's body part that preserves the essential spatial and positional information needed for authentication guidance while replacing the real biometric image with a stylized virtual representation. This allows users to see their body part position without exposing actual biometric data in public viewing environments.
3Object-affected harmful factors
If the electronic device converts the captured image into a virtual character and displays it, then biometric information leakage is prevented, but the system complexity increases due to additional processing modules
Solution Approach 1:
The patent integrates the virtual character generation functionality into the existing biometric authentication system by combining the captured image processing, virtual character generation, and display control into a unified authentication flow. The virtual character generation module works in conjunction with the existing biometric sensor and processor, merging multiple functions into a coordinated system rather than adding completely separate subsystems.

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.
