Iris Authentication Suitability Detection via Face Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric authentication devices face inefficiencies when users cannot acquire high-quality iris data, leading to wasted processing time and user labor, as existing systems do not effectively identify and address unsuitable conditions for iris data acquisition.
Innovation Solution
An information providing device and method that receives a face image, determines suitability for iris data acquisition, and outputs information when a person is unsuitable, preventing further attempts and reducing wasteful processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device repeatedly attempts to acquire iris data from unsuitable users, then authentication success rate may improve, but processing time and user time are wasted
Solution Approach 1:
The system performs preliminary determination of suitability using face image analysis before attempting iris data acquisition. This preliminary action identifies users who are unlikely to provide suitable iris data, preventing wasted processing time on unsuitable users while maintaining the ability to authenticate suitable users effectively
Solution Approach 2:
The face image analysis serves as an intermediary mechanism between the authentication request and the actual iris data acquisition. This intermediary step filters out unsuitable users before the main processing, reducing unnecessary time consumption while preserving authentication success for suitable users
2Loss of information
If the device notifies users of authentication failure causes, then user awareness improves, but users with unresolved issues continue to waste time on repeated attempts
Solution Approach 1:
The system performs preliminary suitability determination before authentication attempts, identifying users who are unlikely to succeed. This allows the system to provide advance information to users about their unsuitability without requiring them to make multiple failed attempts, thereby reducing time loss while maintaining user awareness
3Adaptability or versatility
If the device continues to attempt iris data acquisition from unsuitable users, then authentication opportunities increase, but processing efficiency decreases
Solution Approach 1:
The system performs preliminary face image analysis to determine suitability before initiating iris data acquisition. This preliminary action filters out unsuitable users, reducing the number of futile processing attempts while maintaining authentication opportunities for suitable users, thereby improving processing efficiency without sacrificing adaptability
Solution Approach 2:
The system extracts and removes unsuitable users from the authentication process through face image analysis. By identifying and separating unsuitable users before the main processing, the system maintains authentication opportunities for suitable users while eliminating inefficient processing for unsuitable users, improving overall productivity

AI summary
An information providing device according to one aspect of the present disclosure includes: at least one memory storing a set of instructions; and at least one processor configured to execute the set of instructions to: receive a face image; determine whether a person in the face image is unsuitable for iris data acquisition based on the face image; and output information based on determining that the person is unsuitable for the iris data acquisition when the person is determined to be unsuitable for the iris data acquisition.
