Biometric Authentication System Using Simultaneous Multi-Wavelength Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric authentication processes are often slowed down due to the need for separate steps involving non-biometric identification and biometric feature presentation, which can be cumbersome and prone to fraud.
Innovation Solution
A system that combines the derivation of biometric features and identifiers within a single image data acquisition process, using different wavelengths for image acquisition and potentially invisible identifiers, allowing for simultaneous and secure authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate steps are used for non-biometric identification and biometric feature presentation, then the authentication process can be performed with distinct functional modules, but the authentication time increases and user convenience deteriorates
Solution Approach 1:
The patent combines the identifier acquisition and biometric feature acquisition into a single image capture operation. The imaging device simultaneously obtains both the identifier (e.g., access badge, name tag) and the biometric feature (e.g., fingerprint, iris, face) in one shot, eliminating the need for separate presentation steps and reducing authentication time while maintaining functional distinction through software-based processing separation.
2Reliability
If multiple presentation steps are required, then the system can verify each element separately, but the user operation complexity increases and ease of use deteriorates
Solution Approach 1:
The patent segments the processed information into two distinct components: identifier data and biometric feature data. Although captured simultaneously in a single image, the system separately processes and verifies each component independently through dedicated processing modules, maintaining verification accuracy while simplifying user interaction to a single presentation action.
3Measurement precision
If identifier and biometric feature are captured separately, then dedicated sensors can be used for each, but the system complexity and number of components increases
Solution Approach 1:
The patent employs a multi-functional imaging device that can capture both identifier information and biometric features using the same optical sensor and imaging mechanism. The device is designed to handle different types of data (visual identifiers and physiological features) through software configuration rather than requiring separate physical sensors, thereby reducing system complexity while maintaining acquisition precision through appropriate wavelength selection and processing.
