Biometric Boarding Verification Using Status-Based Passenger Matching

The patent segments the biometric comparison process into multiple stages: initial comparison with a large population database to identify potential matches, followed by secondary verification with a smaller, more focused subset of candidates. This segmentation allows the system to maintain both comprehensive verification capability and high accuracy in the final matching stage.

The patent extracts and separates the biometric comparison task into distinct phases, removing the most computationally intensive broad-matching phase from the final decision-making process. By extracting intermediate matching results and verifying them through additional checks, the system achieves accurate identification without compromising comprehensive verification.

The patent performs preliminary biometric comparisons at the check-in stage, establishing a baseline verification before the passenger enters the secure boarding area. This preliminary action reduces the need for repeated full-scale comparisons later, as subsequent checks can focus on verifying the passenger has not changed identity rather than establishing identity from scratch.

The patent implements continuous but optimized biometric monitoring throughout the boarding process, using incremental verification methods that maintain security without requiring repeated full authentication sequences. The system continuously tracks the passenger's biometric data against the established baseline, providing ongoing security verification with minimal additional processing time.
