Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric authentication systems are vulnerable to impersonation using video presentations of a person's reflection, which can bypass security measures.
Innovation Solution
A biometric authentication system that captures vital information from multiple biological areas using a portable terminal, confirming identity by comparing vital information from different regions to prevent impersonation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is performed using a single biological area, then the authentication process is simple and fast, but the system becomes vulnerable to impersonation attacks using video presentations
Solution Approach 1:
The patent divides the authentication process into multiple segments by capturing vital information from multiple different biological areas (e.g., face, hand, finger) separately. Each area is captured and verified independently, and only when all segments confirm the same identity is authentication granted. This segmentation prevents impersonation attacks while maintaining a structured, manageable process flow.
Solution Approach 2:
The patent adds a temporal dimension to the authentication process by capturing vital information from multiple biological areas at different time points during a predetermined period. This multi-dimensional approach (spatial: multiple areas + temporal: different time points) creates a more robust verification system that cannot be easily replicated by static video presentations.
2Reliability
If multiple biological areas are captured and verified, then impersonation resistance improves, but the authentication time and processing complexity increase
Solution Approach 1:
The patent implements periodic action by capturing vital information from multiple biological areas at different time points within a predetermined period. The system performs repeated capture and verification cycles, comparing results across time points to ensure consistency. This periodic verification strengthens impersonation prevention while keeping the overall authentication time bounded by the predetermined period.
Solution Approach 2:
The system performs preliminary verification of vital information consistency across different biological areas before completing the final authentication. By checking identity confirmation in advance through multiple areas, the system can quickly reject obvious impersonation attempts early in the process, reducing average authentication time for legitimate users while maintaining high security.

AI summary
Authentication is performed by confirming that the true operator presents his/her own biometric authentication information at a common portable information terminal. The biometric authentication system has an image capture unit that acquires first and second image data of different biometric areas of an operator during a predetermined period, a display that displays a guide to guide the operator to the location of the biometric area in order to capture different biometric areas of the operator, and a memory that stores biometric authentication information of the operator in advance. Furthermore, the first vital information and the second vital information are extracted from the image data of the different biometric areas, respectively, the identity of the operator is determined based on the first vital information and the second vital information, and if the identity of the operator is confirmed, the biometric authentication is performed.
