Biometric Authentication for Saliva Test Authenticity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saliva tests face challenges in authenticating that the subject being tested is the intended individual and that the saliva sample is genuine, as imposters can replace the subject or provide samples from others, especially in remote testing scenarios.
Innovation Solution
A device and method utilizing a test plate with a sample receiving area and a camera to capture images or videos that include a plate ID, biometric identifiers of the subject, and the saliva sample, ensuring the sample is from the intended subject by verifying the subject's identity through facial or other biometric features during the sample deposition process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote saliva testing is conducted without authentication, then ease of operation is improved, but reliability deteriorates due to potential sample substitution
Solution Approach 1:
The system performs preliminary authentication actions before the actual testing. A camera captures images of the subject's face and compares them against stored biometric data to verify identity before allowing saliva sample collection. This preliminary verification ensures that only the intended subject can proceed with the test, preventing sample substitution while maintaining remote testing convenience.
2Reliability
If biometric verification is integrated into sample collection, then reliability is improved, but device complexity increases
Solution Approach 1:
The test device integrates multiple functions into a single unit: it serves as both a saliva collection device and a biometric verification system. The camera module is incorporated directly into the test plate assembly, allowing the same device to perform both identity authentication and sample collection without requiring separate equipment, thereby limiting the increase in device complexity.
3Measurement precision
If camera-based authentication is implemented, then measurement precision is improved for subject identification, but loss of time increases due to additional verification steps
Solution Approach 1:
The system replaces manual identity verification processes with automated optical recognition. Instead of requiring operators to manually check identification documents or conduct physical verification, the camera captures facial images and automatically compares them against stored biometric data using image processing algorithms. This substitution of mechanical verification with automated optical recognition improves measurement precision while minimizing time loss through rapid processing.
