Coded Ocular Lens for Changeable Biometric Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eye scanning biometric techniques face issues such as vulnerability to high-resolution images, requirement for close-up scans, accuracy loss with injured eyes, risk of false positives/negatives, privacy concerns, and inability to change compromised biometric data.
Innovation Solution
The use of ocular lenses with embedded or surface-coded security information, which can be changed by the user, for identification purposes, utilizing techniques like physical etching or light reflective coatings, and associated with users through local or remote databases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional eye scanning biometric techniques are used, then biometric identification can be performed, but the system is vulnerable to high-resolution image attacks and cannot be changed if compromised
Solution Approach 1:
The patent applies the Dynamics principle by making the biometric identifier changeable. Instead of using fixed biological characteristics (iris, retina, blood vessels), the system uses coded ocular lenses that users can replace or change. This allows the biometric data to be dynamic and adaptable, resolving the contradiction between security reliability and the ability to change compromised data.
Solution Approach 2:
The patent applies the Copying principle by creating an artificial copy of biometric functionality. Rather than relying on unique biological features, the system uses coded lenses that replicate the identification function. These lenses can be manufactured with specific codes and distributed to users, providing a changeable alternative to immutable biological traits while maintaining identification security.
2Device complexity
If passive imaging is used for eye scanning, then the system is simple and non-intrusive, but it requires close-up scans and is vulnerable to high-resolution image attacks
Solution Approach 1:
The patent applies the Color changes principle by using coded lenses with specific optical properties that reflect or transmit light in distinctive patterns. The codes on the lenses can be designed with varying reflectivity, transparency, or color characteristics that are detectable by imaging devices. This allows identification without requiring close-up scans, as the coded patterns can be read from a distance, improving measurement precision while maintaining relatively simple device complexity.
3Measurement precision
If biological biometric data is used, then unique identification is achieved, but privacy concerns arise and the data cannot be changed if compromised
Solution Approach 1:
The patent applies the Copying principle by replacing sensitive biological information with artificial coded identifiers on lenses. Instead of capturing and storing images of irises, retinas, or blood vessels (which raise privacy concerns), the system uses codes that are deliberately created and can be controlled. Users maintain privacy because the codes are simple identifiers rather than detailed biological data, yet identification accuracy is preserved through the uniqueness of the coded patterns.
Solution Approach 2:
The patent applies the Cheap short-living objects principle by using replaceable coded lenses instead of permanent biological traits. If a code is compromised or privacy concerns arise, users can simply change to different lenses with new codes, similar to replacing disposable items. This provides a practical solution to the inability to change compromised biometric data while maintaining identification accuracy through the unique codes on each lens.
