Innovation Solution
A device with a contact pad containing multiple sensor elements for taking various biometric readings, including electrokinetic energy, electrocardiography, electromyogram, pulse oximetry, and trans-hand impedance data, which processes these readings to confirm user identity and facilitate secure data transfer only when the identity is verified.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fingerprint reading technology is used for biometric verification, then the system is easy to operate, but the security is insufficient and can be bypassed
Solution Approach 1:
The contact pad is divided into multiple sensor elements (first, second, third, and fourth sensor elements) that collectively form a composite biometric profile. Each sensor element captures different aspects of the user's biometric data, and the system requires all elements to match the stored profile, making unauthorized access significantly more difficult while maintaining ease of use
Solution Approach 2:
The system uses a composite biometric verification approach by combining multiple sensor element readings into a single biometric profile. This composite profile requires simultaneous matching of multiple biometric parameters, creating a more secure verification system that maintains user convenience
2Reliability
If multiple biometric sensor elements are used to enhance security, then the security is improved, but the device complexity increases
Solution Approach 1:
Multiple sensor elements are merged into a single contact pad assembly that functions as one integrated verification unit. The processor combines the readings from all sensor elements to generate a composite biometric profile, simplifying the user interaction while maintaining enhanced security through multi-parameter verification
3Speed
If biometric data is stored on the device for verification, then the verification speed is improved, but the risk of unauthorized access to stored data increases
Solution Approach 1:
The system performs preliminary verification by checking multiple biometric parameters simultaneously through the composite profile matching process. This preliminary multi-factor verification ensures that even if data is accessed, unauthorized users cannot bypass the multi-layer biometric checks, enabling fast verification while maintaining security
