Biometric Boarding Data Filtering for Accurate Airport Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric information comparison systems in airports suffer from reduced accuracy due to the large number of populations used for comparison, leading to inefficiencies.
Innovation Solution
An information processing apparatus and method that registers boarding information and biometric data during check-in procedures, allowing for targeted comparisons based on the status of the user's boarding process, and updates status information upon completion of procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric information comparison is performed using a large number of populations (all registered users), then comprehensive security check is achieved, but comparison accuracy decreases and processing time increases
Solution Approach 1:
The patent segments the large population of registered users into smaller groups based on their boarding status. Only users who have completed check-in but not yet boarded are included in the comparison set, separating relevant targets from irrelevant ones to improve comparison accuracy while maintaining security coverage.
Solution Approach 2:
The patent applies local quality by making the comparison set dynamic and context-specific. Instead of uniformly comparing against all registered users, the system adjusts the comparison population based on the specific boarding context, using only locally relevant biometric data from users in the current boarding phase.
2Reliability
If biometric information comparison is performed using a large number of populations, then all potential matches are checked, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary filtering by pre-identifying which users are relevant to the current boarding process based on their check-in status. This preliminary action reduces the comparison set before the actual biometric matching occurs, significantly decreasing processing time while ensuring no relevant matches are missed.
Solution Approach 2:
The patent applies partial action by performing comparisons only on the necessary subset of users rather than the entire registered population. The system does excessive action in terms of status verification and filtering, but partial action in the actual biometric comparison, achieving efficiency without sacrificing completeness for relevant cases.
3Reliability
If all registered biometric information is used for comparison, then no potential matches are missed, but data management complexity increases
Solution Approach 1:
The patent introduces dynamics into the data management system by making the biometric comparison set adaptive and changeable. The set of biometric data used for comparison dynamically updates based on user boarding status, transitioning from a static all-users approach to a dynamic context-aware approach that automatically adjusts to current operational needs.

AI summary
An information processing apparatus includes: an information management unit that registers boarding information on users regarding boarding and biometrics information on the users acquired by a check-in procedure of the users in association with each other; and a comparison unit that compares target biometrics information, which is biometrics information acquired in a procedure up to the boarding for one of the users, with registered biometrics information, which is the biometrics information registered by the information management unit, and the comparison unit selects the registered biometrics information to be compared with the target biometrics information based on status regarding the procedure up to the boarding of the user corresponding to the registered biometrics information.
