Solution Overview

Problem

Current access control systems face inefficiencies due to the need for biometric sensors at the access point, leading to delays, reduced image quality, increased false positives/negatives, and high costs in distributing biometric matching algorithms and processing power across multiple locations, while also requiring strict sequencing of individuals.

Innovation Solution

A two-phase biometric access control system (TBACS) where authentication occurs remotely before arrival, using multiple factors including biometrics, and a unique observable signature is verified at the access point, allowing centralized decision-making and reducing the need for on-site biometric sensors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a biometric sensor is placed at the access control point, then authentication can be performed on-site, but this causes delays and reduces throughput due to the time required to capture and process biometric images

Engineering Contradiction:
Improveauthentication accuracyVSAvoidthroughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs biometric authentication in advance before the individual reaches the access control point. Biometric data is captured and processed remotely, and authorization decisions are made beforehand. This preliminary authentication eliminates on-site processing delays while maintaining security, as the authorized individual can then pass through the access point quickly using a simple verification mechanism.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If biometric authentication is performed at the access control point, then security can be maintained, but the system requires distribution of biometric matching algorithms and processing power across multiple locations, increasing complexity and cost

Engineering Contradiction:
ImprovesecurityVSAvoidsystem distribution complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts the biometric matching algorithm and processing power from the distributed access control points and consolidates them into a centralized remote server. This centralization reduces the complexity at individual locations, as only lightweight verification is needed at access points, while the computationally intensive biometric matching is performed remotely where it can be efficiently managed and updated.

Principle #2Taking out (Extraction)

3Measurement precision

If strict sequencing is enforced at the access control point, then biometric image quality can be maintained, but this reduces flexibility and efficiency in resource utilization

Engineering Contradiction:
Improvebiometric image qualityVSAvoidsequencing flexibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system performs biometric image capture and quality verification in advance, before the individual reaches the access control point. This preliminary action ensures high-quality biometric data is obtained under controlled conditions, while the access control point itself only needs to perform simple verification. This eliminates the need for strict sequencing at the access point, allowing greater flexibility in resource utilization and concurrent access.

AI summary

Current biometric access control systems rely on a biometric sensor at the access control point, a design which has shortcomings on throughput or biometric image quality, which is a particularly important limitation for vehicle traffic, particularly when vehicles do not stop. We disclose a Two-Phase Biometric Access Control System (TBACS) that includes biometric, multi-factor authentication in which the biometric sensor is not required to be at the access control point, the access authorization decision is made prior to arriving, and the access confirmation is verified at the access control point using a unique, observable signature that identifies the person seeking access. The access request may be made manually or may be automated.
