Face Authentication Gate System with Multi-Attempt Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems for gate passage, which rely on face authentication, often struggle with accuracy and efficiency, particularly in scenarios where multiple individuals attempt to pass through simultaneously.
Innovation Solution
The proposed authentication system acquires a face image of a target passing through a gate, performs face authentication by collating the image with registered targets, and determines passage based on the number of successful authentications over multiple attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face authentication is performed multiple times to improve accuracy, then authentication reliability is improved, but processing time increases
Solution Approach 1:
The system performs preliminary face authentication multiple times before final authorization. By conducting preliminary authentication attempts in advance, the system builds up authentication confidence without requiring all attempts to succeed simultaneously for final passage, thus managing time consumption while improving reliability
Solution Approach 2:
The system uses feedback from each authentication attempt to adjust the authorization decision. Successful authentication attempts accumulate to increase confidence level, while failures reduce it. This feedback mechanism allows the system to achieve high reliability through multiple attempts while potentially stopping early if sufficient confidence is reached, managing processing time
2Measurement precision
If multiple face authentication attempts are required, then authentication accuracy is improved, but throughput decreases
Solution Approach 1:
The system conducts preliminary authentication attempts in parallel or sequential manner before final authorization. By preparing multiple authentication results in advance, the system achieves high accuracy through multiple comparisons while maintaining efficient throughput as the preliminary attempts do not block final authorization decisions
Solution Approach 2:
The authentication system dynamically adjusts the number of required successful attempts based on the accumulated authentication results. If multiple successful attempts are achieved quickly, the system can reduce the threshold for final authorization, thereby maintaining high throughput while preserving accuracy through adaptive evaluation

AI summary
An authentication system (10) is provided with: an acquiring means (110) for acquiring a face image of a target (500) passing a gate (200); a face authentication means (120) for performing a face authentication, in which it is determined that whether or not the target is a registered target, by collating information obtained from the face image of the target with information about faces of a plurality of registered targets; and a determining means (130) for determining whether or not the target can pass through the gate on the basis of a number of times of successful authentication when the face authentication is performed a plurality of times. According to such the authentication system, it is possible to properly determine that whether or not a target can pass a gate.
