Multispectral Biometric Imaging for Asymptomatic Carrier Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current thermal imaging cameras rely solely on facial temperature measurements, which are inadequate for accurately detecting COVID-19 infection, particularly in asymptomatic carriers, and are easily circumvented, leading to inaccurate diagnostics and potential spread of the disease.
Innovation Solution
A biometric imaging and biotelemetry system that captures and analyzes a wide range of biometric data using multispectral digital cameras, advanced mathematical algorithms, and blockchain systems to create a subject-specific profile, incorporating visible-light, thermal, and ultraviolet imaging to detect multiple symptomatic, pre-symptomatic, and asymptomatic parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If thermal imaging cameras measure facial temperature to screen for COVID-19, then the screening process is simple and quick, but the diagnostic accuracy is low and many infected people are missed
Solution Approach 1:
The patent divides the facial region into multiple zones (forehead, cheeks, nose, eyes, mouth, chin) and measures temperature, colorimetric, and topographic parameters in each zone separately. This segmentation allows detection of localized abnormalities that single-point temperature measurement misses, improving diagnostic accuracy while maintaining rapid screening capability
Solution Approach 2:
The patent transitions from single-dimensional temperature measurement to multi-dimensional biometric assessment including colorimetric data (skin color changes), topographic data (facial swelling/asymmetry), and temporal patterns. This dimensional expansion enables detection of asymptomatic and pre-symptomatic cases through subtle multi-parameter changes
2Ease of operation
If single-parameter temperature measurement is used, then the device is simple and easy to operate, but it cannot detect asymptomatic carriers effectively
Solution Approach 1:
The patent implements a multi-functional imaging system that simultaneously captures thermal, visible-light, and ultraviolet data using integrated camera modules. This universal device performs multiple diagnostic functions (temperature monitoring, skin color analysis, topographic assessment) in one operation, maintaining ease of use while dramatically improving reliability for detecting asymptomatic carriers
Solution Approach 2:
The system monitors multiple biometric parameters (temperature, colorimetric values, topographic features) and their temporal changes rather than relying on a single static measurement. This parameter-based approach detects subtle physiological changes in asymptomatic individuals while keeping the device operationally simple
3Ease of manufacture
If fixed-location temperature testing stations are used, then implementation is convenient, but they are easily defeated or circumvented
Solution Approach 1:
The patent employs dynamic multi-angle imaging and temporal pattern recognition to detect circumvention attempts. The system captures biometric data at multiple time points and angles, identifying inconsistent patterns that indicate evasion behavior. This dynamic approach maintains convenient fixed-location deployment while resisting circumvention through intelligent analysis

Data Source
AI summary
A biometric imaging and biotelemetry (BIB) system is provided that may be configured to capture, analyze, and process qualitative and quantitative biomarker data acquired from the process of imaging individuals. The BIB system can rapidly measure facial and other body temperatures of a test subject, along with a plurality of other biometric parameters that may be compiled into a subject-specific health profile which, in turn, may provide insights into the wellness or illness of the individual. The BIB system captures biometric data by appropriately configured, multispectral, high resolution digital cameras and sensors. This data is then interconnected to data processing units that employ algorithms, artificial intelligence, and self-learning/deep learning to analyze and process data, render decisions, and manage actions via complex analytical methodologies. The BIB system provides essentially instantaneous analyses that give real-time insights into the wellness or illness of a test subject.
