Solution Overview
Problem
Existing biometric authentication systems require multiple acquisitions of sensitive biometric information, leading to increased psychological load and processing overhead, particularly in accounting and settlement processes.
Innovation Solution
An accounting system utilizing an information display device to image a person, display a code based on their biometric characteristics, and an information processing device to image the code for acquiring accounting information, thereby reducing the need for multiple biometric data acquisitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is performed multiple times for accounting processing, then authentication reliability is improved, but psychological load and processing overhead increase
Solution Approach 1:
The system performs biometric authentication in advance at the time of store entry, registering the user's biometric data beforehand. This preliminary action eliminates the need for repeated authentication during subsequent accounting transactions, reducing psychological load while maintaining security through the pre-registered biometric data.
Solution Approach 2:
Instead of repeatedly capturing and processing original biometric data, the system creates a code representation (copy) of the authenticated user. This code can be imaged multiple times without requiring repeated biometric scanning, significantly reducing processing overhead while maintaining authentication reliability through the verified identity link.
2Reliability
If biometric information is processed multiple times, then accounting security is improved, but processing overhead increases
Solution Approach 1:
The system replaces repeated processing of heavy biometric data with imaging and processing of lightweight code representations. The code serves as a efficient proxy that maintains security verification while dramatically reducing computational resources required for each accounting transaction.
Solution Approach 2:
The system extracts the essential authentication element from the complex biometric data into a simplified code form. This extraction separates the security-critical identity verification function from the resource-intensive biometric processing, allowing secure accounting operations with minimal processing overhead.
3Measurement precision
If biometric information is acquired multiple times, then authentication accuracy is improved, but user convenience deteriorates
Solution Approach 1:
The system performs the accuracy-critical biometric authentication once at entry, establishing verified identity with high precision. Subsequent accounting operations use this pre-verified identity through code imaging, eliminating repeated biometric scanning while preserving authentication accuracy through the established identity link.
Solution Approach 2:
The system creates a reusable code copy from the accurately authenticated biometric data. This code can be imaged multiple times for accounting transactions without requiring repeated high-precision biometric capture, significantly improving user convenience while maintaining authentication accuracy through the verified identity association.
