Solution Overview
Problem
Conventional identification systems face challenges such as time-consuming token-based processes, security vulnerabilities in knowledge-based systems, and resource-intensive biometric methods that can be compromised by unauthorized access and privacy concerns, particularly in contactless fingerprint acquisition systems.
Innovation Solution
A system and method for secure biometric data acquisition using contactless image capture, conversion to binary code, and immediate erasure of original images, with guide components and attachments for mobile devices to facilitate distortion-free image capture and secure password generation, preventing unauthorized access by storing only the binary code for verification purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional biometric systems store original biometric data for verification, then verification accuracy is improved, but security risk increases due to potential data theft and unauthorized access
Solution Approach 1:
The patent extracts only the essential verification information from the original biometric data and stores it in a different format (e.g., transformed templates, hashed values) that cannot be reverse-engineered to reveal the original biometric characteristics. This allows verification to proceed without storing the actual biometric images or raw data, thereby maintaining verification accuracy while eliminating the security risk of storing sensitive original data.
Solution Approach 2:
Instead of storing the original biometric data, the system creates a transformed copy or representation that contains verification information but lacks the sensitivity of the original. This copied representation can be stored and processed for verification purposes without compromising security, as it cannot be used to reconstruct the original biometric data.
2Ease of operation
If contactless image capture is used for biometric acquisition, then user convenience and hygiene are improved, but image quality may deteriorate due to potential distortion
Solution Approach 1:
The patent replaces traditional mechanical contact-based biometric capture (such as fingerprint scanners requiring physical contact) with optical or other non-contact sensing methods. This substitution maintains or improves image quality through advanced optical systems while significantly enhancing user convenience and hygiene by eliminating the need for physical contact between the user and the scanning device.
Solution Approach 2:
The system adjusts various parameters of the image capture process (such as focal length, aperture, illumination angles, and processing algorithms) to optimize image quality for contactless acquisition. By changing these parameters, the system compensates for the challenges of non-contact capture and achieves distortion-free or minimal-distortion images suitable for accurate biometric verification.
3Reliability
If traditional token-based identification is used, then identification capability is provided, but time consumption increases due to application submission and review processes
Solution Approach 1:
The system performs biometric data capture, processing, and template creation during an initial enrollment phase, storing the transformed verification data for immediate use. When identification is needed, the system can instantly compare new biometric inputs against the pre-stored templates without requiring time-consuming application submissions, manual reviews, or physical token verification, thereby dramatically reducing identification time while maintaining accurate identification capability.
