Biometric Authentication Device for Blood Sample Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating blood and exhaled breath samples fail to ensure that the subject being tested is the intended individual and that the sample is genuinely from that subject, leading to potential impersonation or sample substitution.
Innovation Solution
A device and method utilizing a camera to capture images and videos of the subject's biometric identifiers, such as fingerprints, vein patterns, and the blood sample deposition process, to verify the identity of the subject and authenticity of the sample, ensuring that the blood or breath sample is from the intended subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional blood sample collection methods are used, then the testing process is simple and quick, but the authenticity of the subject and sample cannot be verified
Solution Approach 1:
The patent combines multiple authentication functions (biometric scanning, image capture, video recording, sample imaging) into a single integrated testing device. The camera system serves multiple purposes: capturing biometric identifiers, recording the deposition process, and imaging the blood sample, thereby improving reliability without proportionally increasing complexity
Solution Approach 2:
The device performs preliminary authentication actions before the actual blood test. Biometric identifiers are scanned and recorded in advance, and the deposition process is captured from the beginning, ensuring that the subject's identity is verified before the sample is collected
2Reliability
If biometric authentication and video recording are implemented, then sample authenticity is ensured, but the time required for testing increases
Solution Approach 1:
The camera operates continuously throughout the entire testing process, capturing biometric data, the deposition action, and the resulting sample in an unbroken sequence. This continuous recording ensures authenticity without requiring separate authentication steps, thereby minimizing time loss
Solution Approach 2:
The authentication process is segmented into distinct capture phases (biometric identifier, deposition action, sample image) that can be processed and verified separately, allowing for efficient time management while maintaining comprehensive authentication
3Reliability
If multiple biometric identifiers are captured, then impersonation is prevented, but the device complexity and data processing requirements increase
Solution Approach 1:
The camera system serves as a universal capture device for all types of biometric identifiers (fingerprint, vein pattern, facial features) and the blood sample itself. This multi-functional approach allows comprehensive authentication without requiring separate specialized devices for each biometric type
