Biometric Security Screening Using Real-Time Credential Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional security screening processes are burdensome for individuals and providers, as they require physical tokens like boarding passes and identification, which can be forged and are difficult to verify, especially regarding their validity and cancellation status.
Innovation Solution
Implementing a biometric-based security screening system that uses biometric data to look up identifiers and retrieve electronic pass information, allowing for token-less security screening and processing, such as boarding pass-less airport security, by communicating with a back-end system to verify travel credentials and security status in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical tokens (boarding passes, ID) are used for security screening, then verification of travel credentials can be performed, but the process becomes burdensome and tokens can be forged or invalidated
Solution Approach 1:
The patent replaces the mechanical system of physical tokens (boarding passes, ID cards) with a biometric-based electronic verification system. Biometric data (fingerprint, facial recognition) is captured and used to query a database for travel credentials, eliminating the need for physical documents that can be forged or lost. This substitution maintains reliability while improving ease of operation.
Solution Approach 2:
The patent creates an electronic copy of the verification process where biometric data serves as a key to retrieve travel credential information from a database. Instead of verifying physical tokens, the system queries and displays electronic boarding pass information, ticket status, and security clearance based on the biometric match. This copying approach eliminates forgery risks while simplifying the screening process.
2Reliability
If physical tokens are required for security screening, then travel credentials can be verified, but verification of validity and cancellation status becomes difficult
Solution Approach 1:
The patent implements a feedback mechanism where the biometric verification system queries a centralized database and receives real-time feedback on the status of travel credentials. The system retrieves and displays current boarding pass information, ticket validity status, and security clearance levels. This feedback loop ensures that only valid, non-cancelled credentials are approved, maintaining high reliability while the automated process reduces verification complexity.
3Ease of operation
If biometric data is used for token-less security screening, then the need for physical tokens is eliminated and processing is simplified, but real-time validation of travel information must be implemented
Solution Approach 1:
The patent performs preliminary actions by pre-storing travel credential information and biometric data in a centralized database before the security screening event. When a passenger approaches the screening point, the system quickly retrieves pre-prepared boarding pass information, ticket status, and security clearance data based on biometric matching. This preliminary preparation eliminates the need for complex real-time validation while simplifying the actual screening process for users.
Data Source
AI summary
In physical token-less security screening using biometrics, a person provides biometric data to a security computing device as part of a security screening. The biometric data is used by the security computing device to look up an identifier (such as an airline account identifier or a security status identifier) for the person from a security back end. The identifier is used by the security computing device to obtain electronic pass information (such as an electronic boarding pass or a security screening status indicator) from a third party computing system (such as an airline computing system or a clearinghouse), which may be used to clear the person and/or otherwise facilitate the security screening. In some implementations, these techniques may also be used for physical token-less pass processing (such as boarding pass-less airline processing, confirmation of assigned traveling credentials, or determination of security protocols).
