Cognitive Access Control via Baseline Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems cannot effectively assess and ensure that authorized individuals possess adequate cognitive abilities, particularly in situations involving high risk or hazard, as they only verify identity without evaluating cognitive capability.
Innovation Solution
A cognitive level identification device that administers tests to assess cognitive capabilities, comparing user performance to a baseline, and provides an enable/disable signal for access to controlled units or systems only when the cognitive level is deemed sufficient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ID verification means are used to ensure authorized access, then unauthorized persons are prevented from entering controlled premises or operating equipment, but cognitive capability of authorized persons is not assessed
Solution Approach 1:
The patent combines identity verification and cognitive capability assessment into a single integrated access control system. The cognitive assessment module is merged with the existing ID verification means, allowing both functions to operate together seamlessly. This resolves the contradiction by adding cognitive assessment without requiring a completely separate verification system.
Solution Approach 2:
The access control system is enhanced to perform multiple functions: traditional ID verification and cognitive capability assessment. The system universally handles both authorized personnel identification and real-time cognitive state evaluation, allowing a single system to address both security concerns about unauthorized access and impaired operation.
2Object-affected harmful factors
If cognitive capability assessment is added to access control, then safety of high-risk operations is improved, but system complexity and processing time increase
Solution Approach 1:
The cognitive assessment uses a simplified subset of cognitive tests focused specifically on detecting impairment states rather than comprehensive cognitive evaluation. This partial assessment approach provides sufficient safety verification for access control purposes while minimizing the time required, avoiding the need for extensive cognitive testing.
Solution Approach 2:
The system performs preliminary cognitive baseline assessment during enrollment, storing reference data for later comparison. During actual access attempts, only rapid comparison against the baseline is needed, significantly reducing the time required at the point of access while maintaining accurate detection of cognitive impairment.
3Measurement precision
If comprehensive cognitive testing is implemented, then accurate detection of cognitive impairment is achieved, but ease of operation and user convenience deteriorate
Solution Approach 1:
The system replaces complex mechanical or manual cognitive testing with automated electronic assessment delivered through a display device and processed by a controller. Users interact through simple input devices while the system automatically administers cognitive tests and evaluates results, maintaining high detection accuracy while improving ease of operation.
Solution Approach 2:
The cognitive assessment system automatically administers tests, processes responses, and evaluates cognitive state without requiring manual intervention from operators or security personnel. The system serves itself by autonomously completing the entire assessment workflow, reducing operational complexity and improving user convenience.
Data Source
AI summary
A cognitive ability level identification device is disclosed. The device is configured to present cognitive test to a user and to measure the user's response to the test. When the user fails the test, the device is configured to prevent the user from operating equipment and/or take any subsequent action, activity or process or to prevent the user from entering secured locations due to poor cognitive performance. A method for evaluating the user's cognitive performance is disclosed, by presenting to the user cognitive tests and comparing the user's actual performance to pre acquired cognitive performance baseline.
