Exit Gate Biometric Verification with Approach and Stop Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing gate apparatuses face challenges in allowing users to pass through quickly due to difficulties in capturing biometric data efficiently, particularly when the user's face is not directly facing the camera or when wearing items obstruct the authentication process.
Innovation Solution
The gate apparatus incorporates biometric information acquisition units to capture biometric data from users approaching or stopping in front of the exit gate, with adaptive door control mechanisms to open the gate based on successful biometric comparisons, even when initial attempts fail or face orientation is incorrect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single biometric verification attempt is performed, then the authentication process is simple and quick, but the success rate decreases when the user's face is not properly aligned or is obstructed
Solution Approach 1:
The system performs preliminary biometric verification attempts while the user is still approaching the gate (before complete stopping), allowing multiple verification opportunities to be established in advance. This ensures that even if the initial verification fails due to alignment or obstruction issues, the authentication process has already been initiated and can continue seamlessly
Solution Approach 2:
The system implements a feedback mechanism where the result of each biometric verification attempt is used to determine whether to proceed to the next attempt or to open the gate. When verification fails, the system automatically triggers the next verification attempt rather than requiring manual intervention, thus maintaining both high reliability and quick passage time
2Reliability
If multiple biometric verification attempts are allowed, then the authentication success rate improves, but the complexity of the system increases
Solution Approach 1:
The biometric verification process is segmented into distinct attempts, each with its own verification logic and decision criteria. The system divides the authentication process into multiple independent verification stages, where each stage can operate autonomously based on its own success or failure conditions, thereby managing complexity through structured segmentation
3Reliability
If the gate remains closed during verification, then security is maintained, but the user experience deteriorates when verification takes longer
Solution Approach 1:
The gate system dynamically adjusts its state based on the verification progress and outcome. Rather than maintaining a static closed state throughout the entire verification process, the gate can transition between closed and open states according to real-time verification results, optimizing both security and user experience through dynamic control

AI summary
A gate apparatus includes: an exit gate door; a first biometrics information acquisition unit that acquires, from a user who moves toward the exit gate door in a closed state, first target biometrics information to be compared with registered biometrics information registered in advance; a second biometrics information acquisition unit that acquires second target biometrics information to be compared with the registered biometrics information from the use who stops in front of the exit gate door when there is no matching in a comparison between the first target biometrics information and the registered biometrics information or the comparison is unable to be performed; and a door control unit that opens the closed exit gate door in accordance with a result of a comparison between the first target biometrics information or the second target biometrics information and the registered biometrics information.
