Face And Gaze Authentication Control for Secure User Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a more convenient and secure user authentication method that combines face authentication with gaze tracking to enhance security and usability, particularly in scenarios like electronic payments and vehicle operations.
Innovation Solution
An electronic device equipped with a camera for face recognition and gaze tracking, performing dual authentication by matching the recognized face with stored face authentication information and tracking the gaze movement along predefined patterns on the device, allowing authentication even when the screen is off and in vehicle environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face authentication is used alone, then convenience is improved, but security is insufficient
Solution Approach 1:
The patent combines face authentication with gaze movement authentication into a unified dual-factor authentication system. The controller performs both face recognition and gaze pattern verification simultaneously, merging two authentication modalities to achieve both convenience and security. This resolves the contradiction by integrating multiple authentication methods rather than using face recognition alone.
Solution Approach 2:
The authentication system uses composite verification by combining facial biometric data with gaze movement patterns. The controller processes both types of biometric information together to make authentication decisions, creating a composite authentication mechanism that leverages the strengths of both methods while mitigating their individual weaknesses.
2Reliability
If dual authentication using face and gaze tracking is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The camera module serves multiple functions: it captures images for face recognition and simultaneously tracks gaze movements through pupil detection. This multi-functionality reduces the need for separate sensors and components, thereby limiting the increase in device complexity while achieving dual authentication. The controller also performs both authentication tasks using the same hardware resources.
Solution Approach 2:
The system uses the user's own facial features and gaze patterns as authentication credentials, eliminating the need for external tokens, cards, or additional security devices. The authentication data is derived entirely from the user's natural physiological characteristics, reducing system complexity while maintaining high security.
3Reliability
If gaze movement tracking is added to face authentication, then authentication security is enhanced, but processing time increases
Solution Approach 1:
The camera continuously captures images during the authentication process, and the controller simultaneously processes both face recognition and gaze tracking in real-time. Rather than performing face authentication first and then separately performing gaze tracking, the system conducts both analyses concurrently on the continuous image stream, reducing overall authentication time while maintaining security.

AI summary
An electronic device and a control method therefor are disclosed. The present invention comprises: a camera; a memory for storing user face authentication information and an authentication pattern; and a control unit for recognizing a face from an image acquired through the camera, performing a first authentication that determines whether the recognized face matches the face authentication information, tracking the movement of a gaze of the recognized face when the first authentication is completed, and performing a second authentication that determines whether the movement of the gaze matches the authentication pattern. According to the present invention, a dual authentication step using the face authentication information and the movement of the gaze of the user can be conveniently performed.
