Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a high quality and highly accurate biometric system is used to initially establish identity, then identification accuracy is improved, but system cost and complexity increase
Solution Approach 1:
The biometric assurance process is divided into two segments: initial identification using a high-quality biometric system, and subsequent verification using a simpler comparison system. This segmentation allows the complex high-accuracy system to be used only when necessary for initial identification, while routine verification uses a simpler, more cost-effective system.
Solution Approach 2:
The system performs preliminary action by capturing and storing a high-quality initial biometric indication during the identification phase. This preliminary capture allows subsequent verification to use a simpler comparison process without needing to repeatedly engage the complex high-accuracy biometric system.
2Ease of operation
If a portable biometric assurance system is implemented, then accessibility and ease of deployment are improved, but system reliability may worsen
Solution Approach 1:
The system creates a copy of the initial biometric indication and stores it for later comparison. This copying approach allows the portable system to perform reliable verification by comparing subsequent biometric readings against the stored copy, maintaining reliability while enabling portability.
Solution Approach 2:
The system performs preliminary action by capturing and storing a high-quality initial biometric indication during the identification phase. This preliminary capture allows subsequent verification to use a simpler comparison process without needing to repeatedly engage the complex high-accuracy biometric system.
3Reliability
If static biometric indications are compared over time, then identity assurance is improved, but susceptibility to sensor movement errors increases
Solution Approach 1:
The system dynamically adjusts the comparison process by evaluating whether changes in biometric patterns exceed a threshold that would indicate sensor movement versus actual identity changes. This dynamic approach allows the system to maintain reliable identity assurance while compensating for minor sensor movements that occur during portable use.

AI summary
The invention may be embodied as an identity assurance system or method. A system according to the invention may have a biometric sensor capable of providing static biometric indications, a strap capable of positioning the sensor on an organism, and a computer in communication with the sensor. The computer may have software running on the computer in order to (a) cause the computer to determine whether there is a match between a subsequent static biometric indication and an initial static biometric indication, and (b) cause the computer to send a signal indicating whether a match was determined in order to assure the identity of the organism.
