Retina Biometric Authentication via Dynamic Eye Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biometric systems face challenges in distinguishing between original and reproduced biometric objects, such as fingerprints or irises, leading to uncertainty in identification and authentication, and are vulnerable to manipulation.
Innovation Solution
The method and system utilize the retina as a biometric object, incorporating eye movements and focusing patterns to securely communicate with the biometric system, making it difficult for reproductions to participate in the authentication process, with the use of a biometric retina laser scanner and LED targets to verify the authenticity of the eye movements and focusing patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional biometric methods (fingerprint, iris, face) are used for identification, then the system is easy to operate and implement, but the system is vulnerable to reproduction and copying attacks
Solution Approach 1:
The patent introduces dynamic elements by requiring the user to perform specific eye movements (tracking a moving target or following a path) during authentication. This dynamic behavior cannot be replicated by static reproductions or photographs, thereby enhancing security while maintaining operational simplicity through guided user interaction.
Solution Approach 2:
The authentication process employs periodic actions through sequential verification steps: first verifying the retina image, then verifying eye movement patterns, and optionally combining both. This multi-stage periodic verification process systematically eliminates reproduction attacks while maintaining user-friendly operation.
2Ease of operation
If the biometric object is freely accessible (as with fingerprints or irises), then the system is easy to use, but reproductions can easily deceive the system
Solution Approach 1:
The patent introduces an intermediary verification process involving the brain-eye coordination system. The user must consciously track a visual target with their eye movements, creating a behavioral intermediary layer between the biometric sample and the authentication decision. This intermediary step prevents direct use of reproductions since they cannot perform conscious tracking.
Solution Approach 2:
The system changes the verification parameters from static biometric features alone to a combination of static retina characteristics and dynamic eye movement patterns. By adding the temporal dimension of eye movement tracking, the system transforms the authentication parameters to exclude reproduction attacks while maintaining ease of use through natural eye tracking behavior.
3Measurement precision
If static biometric characteristics are used for verification, then the verification process is simple and quick, but the system cannot distinguish originals from reproductions
Solution Approach 1:
The patent captures dynamic eye movement information by tracking the position and trajectory of the user's eye as it follows a visual target. This dynamic behavioral information is extracted and verified against stored patterns, adding a layer of authentication that preserves behavioral characteristics while improving the ability to distinguish originals from reproductions.
Solution Approach 2:
The system implements feedback by continuously monitoring eye position during the tracking task and comparing it against the expected movement pattern stored during enrollment. This real-time feedback mechanism ensures that the dynamic behavioral information is accurately captured and verified, enhancing measurement precision without losing behavioral nuances.
