Handheld Eye Movement Authentication for Voluntary Password Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current password input methods for safety deposit boxes and security systems are vulnerable to password leakage or reproduction due to the visibility of input processes, and existing biometric systems cannot ensure that the password is entered voluntarily.
Innovation Solution
An authentication system utilizing a handheld control apparatus that captures and analyzes eye-open and eye-closed states to generate a blink code, which is used to control security equipment, providing a secure and voluntary input method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional keyboard password input is used, then ease of operation is improved, but security is worsened due to password leakage risk
Solution Approach 1:
The patent replaces the mechanical keyboard input system with an optical-based eye movement detection system. The image capturing unit records eye movements, and the processing unit analyzes these movements to generate authentication codes, substituting physical keyboard interaction with automated visual tracking to eliminate password leakage risks
Solution Approach 2:
The patent introduces eye movement patterns as an intermediary between the user and the authentication system. Instead of directly inputting passwords through keyboards, the user's natural eye movements are captured and converted into authentication codes, creating a indirect but secure authentication pathway that prevents password exposure
2Measurement precision
If iris recognition or fingerprint recognition is used, then authentication accuracy is improved, but reliability is worsened because these biometric data can be reproduced
Solution Approach 1:
The patent employs dynamic eye movement patterns rather than static biometric data. Eye movements are continuous, variable, and difficult to reproduce compared to fixed iris or fingerprint patterns. The system captures sequences of eye movements over time, creating a dynamic authentication mechanism that resists replication
Solution Approach 2:
The system performs preliminary analysis of eye movement patterns to establish authentication codes before final verification. The processing unit pre-processes the captured eye movement data, converts it into standardized codes, and compares these codes against stored authentication patterns, ensuring voluntary and accurate authentication
3Reliability
If eye movement detection is implemented, then security is improved by ensuring voluntary password input, but device complexity is worsened
Solution Approach 1:
The patent integrates multiple functions into the handheld control apparatus: the image capturing unit serves both for eye movement detection and general visual input, the processing unit handles both eye movement analysis and code generation, and the reflective mirror system supports both illumination and image reflection. This multi-functionality reduces the need for separate dedicated components
Solution Approach 2:
The patent combines the image capturing unit, light source, reflective mirror, and processing unit into a single integrated handheld control apparatus. By merging these components, the system achieves compact form factor while maintaining eye movement detection capability, reducing overall system complexity compared to distributed components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances security by making eye movements difficult to observe, ensuring that passwords are entered voluntarily and reducing the risk of leakage, thereby improving the security of access control systems and safety deposit boxes.
Implementation Method 1
The image capturing unit is disposed within the housing case to capture an eye area of the user through the window to obtain an image sequence
Implementation Method 2
The light source is disposed in the housing case, and adjacent to the window
Data Source
AI summary
An authentication system controlled by eye open and eye closed state and a handheld control apparatus thereof are provided. The handheld control apparatus includes a housing case, an image capturing unit and a processing unit. The housing case has a window and is suitable for a user to hold. The image capturing unit is disposed in the housing case and captures an eye area of the user through the window to obtain an image sequence. The processing unit is coupled to the image capturing unit and analyzes the image sequence to obtain eye image information of the eye area of the user. The processing unit detects an eye-open state and an eye-closed state of the user based on the eye image information, converts a plurality of the eye-open states and the eye-closed states into a blink code, and accordingly generates a control command to control a security equipment.
