Biometric Exclusion System for Casino Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to efficiently prevent a small subset of individuals from entering a facility without causing undue delay or hardship for the majority, particularly in applications like casinos where a list of excluded individuals needs to be screened from a large population.
Innovation Solution
A biometric exclusion system using biometric acquisition and matching, combined with a database, to screen subjects by enrolling them into a database and matching against it, allowing for efficient denial of access to excluded individuals while allowing the majority to enter without hindrance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual screening methods are used to check excluded individuals, then security reliability is improved, but processing time and efficiency deteriorate
Solution Approach 1:
The patent replaces manual mechanical screening processes with automated biometric recognition systems. Fingerprint sensors, facial recognition cameras, or iris scanners automatically capture and compare biometric data against exclusion databases, eliminating the need for manual identity verification while maintaining high security reliability and significantly improving processing throughput.
Solution Approach 2:
The system creates and stores biometric templates (digital copies of physical biometric traits) in a database. These templates serve as reusable references for rapid comparison against incoming biometric data, enabling efficient bulk screening without repeatedly accessing original biometric sources or requiring manual intervention.
2Measurement precision
If comprehensive biometric screening is applied to all individuals, then detection accuracy for excluded persons is improved, but processing time for the majority increases
Solution Approach 1:
The system applies biometric screening selectively rather than uniformly to all individuals. By using quick preliminary checks and only performing full biometric verification when there is a match or suspicion, the system maintains high detection accuracy for excluded persons while minimizing processing time for the majority who are cleared quickly.
Solution Approach 2:
The system performs preliminary biometric capture and initial database matching before full verification. This preliminary action quickly identifies potential matches that require further attention, while allowing non-matches to be processed rapidly, thus maintaining high detection accuracy without uniformly increasing processing time for all individuals.

AI summary
A system for biometric exclusion of certain individuals from entering a facility. A biometric exclusion system may use biometric acquisition and matching and a database to screen a large population of subjects by looking for individuals enrolled in a database. A screening approach may be used to match biometrics having sufficient quality of any individuals attempting to enter the facility, relative to biometrics of individuals stored in the database. A biometric, such as that of a face or an iris, of an individual may be obtained with the individual's knowledge or cooperation. The database may have biographical information pertinent to an individual having a biometric in the database. There may be an associated system which may be used to enroll individuals by entering their biometrics in the database.
