Biometric Authentication via Eye Wink Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods using biometric data and authorization codes can be insecure, as they require manual input, which may be vulnerable to observation and are cumbersome, failing to provide a high level of convenience and security.
Innovation Solution
A method utilizing an optical device with an iris scanner and eye-tracking capabilities to receive inputs from eye winks, converting these into numeric values for secure and hands-free authentication and authorization processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of authorization code is used, then user can complete transaction, but security is compromised due to observation vulnerability
Solution Approach 1:
The patent replaces manual mechanical input (typing authorization code) with optical detection systems (eye-tracking devices, iris scanners) that automatically capture biometric data. This substitution eliminates the vulnerability of manual input to observation while maintaining ease of operation through automatic detection.
Solution Approach 2:
The patent introduces an intermediary optical detection system that mediates between the user and the authentication system. The eye-tracking device and iris scanner act as intermediaries to capture authentication data without requiring direct manual input, thereby preventing shoulder-surfing attacks while keeping the process convenient.
2Ease of operation
If biometric data alone is used for authentication, then operation is simplified, but security level is insufficient
Solution Approach 1:
The patent merges multiple authentication factors into a unified process: biometric authentication (iris scan) is combined with authorization code input (via eye-tracking). This combination maintains the simplicity of biometric authentication while enhancing security through the additional authorization layer, resolving the contradiction between operational simplicity and security adequacy.
3Reliability
If hand input is required for authorization code, then security may be maintained, but user convenience deteriorates and hands must be free
Solution Approach 1:
The patent replaces manual hand input with optical eye-tracking detection. The eye-tracking device captures eye movements and patterns to derive authorization codes, eliminating the need for hand input while maintaining security. This allows users to authenticate even when their hands are occupied, significantly improving convenience without compromising security.
