Gaze Tracking Password Input Using Eye Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current password input methods are vulnerable to unauthorized access and coercion, as they can be easily intercepted or copied, and do not ensure that the user is entering the password willingly.
Innovation Solution
A gaze tracking password input method using a device with a photographing unit, display unit, and operation unit that detects and verifies a user's gaze on specific numerals, characters, or symbols to input a password, ensuring that the user is conscious and willing, and sends a rescue signal if a help-seeking script is activated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional keyboard password input is used, then password input is simple and fast, but password security is compromised due to spying, fingerprint copying, and coercion
Solution Approach 1:
The patent replaces the mechanical keyboard input system with an optical gaze tracking system. The photographing unit captures images of the user's eyes, and the operation unit analyzes eye movement to determine password input, substituting physical keyboard interaction with optical detection of visual attention
Solution Approach 2:
The patent introduces an intermediary visual interface between the user and the password verification system. The display unit shows the password input interface, and the photographing unit mediates by capturing eye position data, creating an indirect input method that prevents direct observation of password entry while maintaining user control
2Measurement precision
If iris identification is used, then identification accuracy is improved, but the system cannot verify if the person is acting under free will
Solution Approach 1:
The patent transitions from static iris identification to dynamic gaze tracking. Instead of capturing a fixed biometric feature, the system continuously monitors eye movement and visual attention over time, analyzing the dynamic pattern of where the user looks on the password interface to verify voluntary participation
Solution Approach 2:
The system provides visual feedback through the display unit showing the password input interface, and receives feedback through the photographing unit capturing eye position. This closed-loop feedback mechanism allows the system to verify that the user is actively and voluntarily following the password input process
3Ease of operation
If fingerprint or palm print identification is used, then password input is eliminated, but the system is vulnerable to print copying and cannot detect coercion
Solution Approach 1:
The patent replaces contact-based biometric systems (fingerprint/palm print scanners) with non-contact optical gaze tracking. This eliminates the need for physical contact that could leave copies of biometric data, while maintaining ease of operation through natural visual interaction
Solution Approach 2:
The patent avoids creating copies of sensitive biometric data by using gaze tracking instead of fingerprint or palm print scanning. Eye position data is processed in real-time without creating storable replicas, preventing the copying vulnerability inherent in contact-based biometric systems
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
This method effectively prevents password leakage and ensures that the user is entering the password voluntarily, applicable to various security systems, including locks and automatic cash dispensers, by using a gaze tracking system to authenticate and authorize access.
Implementation Method 1
the operation unit identifying the person's approach; focusing the person's eyes onto an input zone to carry out the input of a password
Data Source
AI summary
A gaze tracking password input method and a device utilizing the same wherein the method includes the following steps: picking up photo images of a person's eyes by a photographing unit which continually takes photo shots at a particular area as the person approaches to the photographing unit and his eye enters the particular area; transmitting the photo images taken at the particular area to an operation unit; setting a script associated with a particular point as a password; and then determining the person's gaze tracking direction which indicates the script to be input by the operation unit. The operation unit comparing the multiple input scripts with predetermined passwords, if the input scripts are matched with the predetermined passwords, then the person is officially authorized.
