Biometric Passenger Matching by Boarding Status Segmentation
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 all registered biometric information is used for comparison, then the system can handle various boarding scenarios, but the comparison accuracy decreases due to the large number of populations being compared
Solution Approach 1:
The patent segments the biometric information database into multiple groups based on boarding status. The comparison unit selectively accesses only the relevant group (e.g., checked-in passengers only) rather than comparing against all registered biometric information. This segmentation reduces the number of comparisons needed while maintaining comprehensive coverage of applicable scenarios.
Solution Approach 2:
The system performs preliminary filtering by boarding status before the actual biometric comparison. The comparison unit first determines the boarding status of the target passenger and then selects only the biometric records corresponding to that status for comparison. This preliminary action eliminates irrelevant comparisons in advance, improving accuracy by reducing noise from unrelated populations.
2Reliability
If biometric comparison is performed at multiple checkpoints throughout the airport, then passenger tracking is improved, but the time required for each comparison increases
Solution Approach 1:
The system performs preliminary grouping of biometric information by boarding status before comparison. When a biometric check is performed at any checkpoint, the comparison unit quickly determines the passenger's boarding status and retrieves only the corresponding pre-grouped records for comparison. This preliminary organization significantly reduces comparison time while maintaining accurate tracking across multiple checkpoints.
Solution Approach 2:
The patent divides the biometric database into distinct segments based on boarding procedures completed. Each segment contains biometric records for passengers with specific boarding statuses. This segmentation allows the system to perform rapid comparisons at any checkpoint by accessing only the relevant segment, reducing processing time while maintaining comprehensive tracking capability.
3Adaptability or versatility
If the system stores and manages biometric information for all passengers through all boarding procedures, then comprehensive tracking is achieved, but the system complexity increases
Solution Approach 1:
The patent implements segmentation of biometric data by boarding status, creating distinct groups for different procedural states (e.g., checked-in, security cleared, boarding). This segmentation simplifies data management by organizing information into manageable, status-specific subsets rather than a single large database, reducing complexity while maintaining comprehensive tracking coverage.
Solution Approach 2:
The system performs preliminary organization of biometric information according to boarding status before any comparison operations. This preliminary categorization creates a structured framework that simplifies subsequent data retrieval and management operations, reducing system complexity while enabling comprehensive tracking across all boarding procedures.

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.
