Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable identification devices face issues with reliability due to 'aging' of biometric features, susceptibility to tampering, and complex authentication processes, leading to false identifications and unauthorized access.
Innovation Solution
A portable recognition device that stores biometric reference parameters during initialization and updates them chronologically, using dual or multiple-parameter detection methods, and incorporates a data protection system with electrical separation of biometric and enabling data, ensuring secure and reliable authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If biometric features are stored and used for authentication, then identification capability is improved, but reliability deteriorates due to aging and variability of biometric features over time
Solution Approach 1:
The patent implements a dynamic biometric reference parameter update mechanism where reference parameters are automatically updated over time to reflect changes in the holder's biometric features. The system transitions from static reference data to dynamically adapting reference data, allowing the authentication system to remain reliable despite natural aging and variability of biometric traits.
Solution Approach 2:
The system changes the temporal parameter of biometric reference data by introducing chronological updates. Instead of using a single fixed reference point, the system maintains and updates reference parameters at different time points, adjusting the authentication criteria to account for parameter evolution over time.
2Adaptability or versatility
If biometric data is stored in the document, then identification functionality is improved, but susceptibility to tampering and unauthorized access increases
Solution Approach 1:
The patent divides the identification document into functionally separate parts: a first part containing biometric reference parameters and a second part containing enabling data. This segmentation isolates sensitive biometric data from other document functions, limiting the impact of potential tampering and requiring separate access controls for different data types.
Solution Approach 2:
The system introduces an intermediary update mechanism that chronologically manages biometric reference parameters. This intermediary layer controls access and updates to biometric data, providing an additional security buffer between potential tampering attempts and the core biometric information.
3Measurement precision
If multiple biometric parameters are detected and stored, then authentication accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal biometric detection framework within the portable device that can handle multiple biometric parameter types (facial features, fingerprints, iris patterns, etc.). Rather than implementing separate specialized systems for each biometric type, the device uses a unified multi-functional approach that reduces overall system complexity while maintaining high authentication accuracy.
