Group Authentication System Using Biometric Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems do not efficiently authenticate groups, such as families or travel companions, by focusing on individual member configurations rather than group dynamics.
Innovation Solution
An authentication system that includes biometric authentication and condition setting means to efficiently authenticate groups by setting group authentication conditions based on attribute information of authenticated group members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If biometric authentication is performed for each individual member of a group, then authentication accuracy is maintained, but authentication processing time increases
Solution Approach 1:
The authentication process is segmented into two distinct phases: first, representative authentication where only one member of the group undergoes full biometric verification, and second, group authentication where other members are authenticated based on their relationship to the representative. This segmentation reduces the total number of biometric verification operations while maintaining security through the representative's authenticated status.
Solution Approach 2:
The system performs preliminary authentication by verifying the representative member first, then uses this preliminary authentication result to establish group authentication conditions. Subsequent members are authenticated more quickly by comparing their attributes against the already-authenticated representative, eliminating the need for repeated full biometric verification processes.
2Reliability
If strict personal authentication criteria are applied to all group members, then security is maintained, but group authentication efficiency decreases
Solution Approach 1:
Different authentication criteria are applied to different members based on their role in the group. The representative member undergoes strict biometric authentication to ensure security, while other members use simplified authentication based on their relationship attributes to the representative. This local differentiation of authentication quality maintains security through the representative while improving overall group authentication efficiency.
Solution Approach 2:
The authentication system dynamically changes the authentication parameters based on the member's role. For the representative, full biometric verification parameters are applied, while for other members, the parameters are adjusted to use attribute comparison against the representative's authenticated data, thereby improving efficiency without compromising security.
3Speed
If group authentication conditions are set based on attribute information, then authentication speed improves, but system complexity increases
Solution Approach 1:
The system performs preliminary setup by storing attribute information and group relationships in advance. When authentication is needed, the pre-stored attribute data is quickly compared against the representative's authenticated information, enabling fast group authentication without complex real-time processing. The complexity is shifted to the initial data setup phase rather than the authentication execution phase.

AI summary
An authentication system (1) is a system for authenticating a predetermined group. The authentication system (1) includes an authentication unit (11) and a condition setting unit (12). The authentication unit (11) performs biometric authentication of a person on the basis of a predetermined personal authentication criterion. The condition setting unit (12) sets a group authentication condition for another member in the group to which the person belongs on the basis of attribute information of the authenticated person. The authentication unit (11) authenticates another member on the basis of the set group authentication condition.
