Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biometric identification systems are inadequate for detecting and identifying individuals from a distance and in uncontrolled environmental conditions, requiring close proximity and controlled settings, which limits their applicability in scenarios like airports and border crossings.
Innovation Solution
A system utilizing UV image data with a database of binary sequences representing skin areas, a query module, detection module, sequence module, and match module to identify individuals by forming target binary sequences and comparing them to database entries, enabling identification from over 50 meters away without direct contact or controlled conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional biometric sensors (fingerprint, eye, facial scanners) are used, then identification accuracy is maintained, but the system requires close proximity and controlled environmental conditions
Solution Approach 1:
The patent changes the fundamental parameter of detection wavelength from visible light to ultraviolet spectrum. This enables the system to detect skin areas and textures at distances over 50 meters while maintaining identification accuracy, as UV imaging captures unique skin characteristics that are visible at distance and work in uncontrolled environmental conditions
2Loss of information
If sensors requiring direct contact or close proximity are used, then detailed biometric information can be obtained, but the system cannot operate from distances greater than 50 meters
Solution Approach 1:
The patent replaces traditional mechanical contact-based sensing with optical ultraviolet imaging. This substitution allows the system to capture detailed skin area information from distances greater than 50 meters without requiring physical contact or close proximity, thereby maintaining biometric information quality while extending detection distance
3Ease of operation
If conventional biometric systems are used, then identification can be performed with user cooperation, but the system fails in uncontrolled environmental conditions (cloudy, humid, windy)
Solution Approach 1:
The patent changes the operational parameter from visible light detection to ultraviolet spectrum imaging. UV imaging captures skin areas and textures that are independent of atmospheric conditions, enabling the system to maintain reliable operation in uncontrolled environments such as cloudy, humid, or windy conditions where traditional visible light-based biometric systems fail
Applied Scientific Principles

Data Source
AI summary
A system and method for biometric identification of a target individual based on a query containing UV image data of the target individual. In one embodiment, the system includes a first database, a query module, a detection module, a sequence module and a match module. The first database includes a plurality of identities with each identity having at least one binary sequence representative of a skin area of that identity. The query module receives the query and validates the UV image data. The detection module detects at least one skin area in the UV image data. The sequence module forms at least one target binary sequence corresponding to the at least one skin area. The match module searches the first database based on the at least one target binary sequence to identify at least one identity thereby facilitating biometric identification of the target individual.
