Gaze Tracking Visual Story Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional text-based password authentication systems are insecure due to easily guessable short passwords and difficult-to-remember long passwords, lacking a balance between security and usability.
Innovation Solution
A biometric and storytelling-based authentication system that uses dynamic visual stories and gaze tracking to authenticate users by selecting correct images from a set, leveraging user-specific metadata from social media profiles and employing decoy images to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If text-based passwords are used for authentication, then the system is easy to operate, but the security is weak due to easily guessable passwords
Solution Approach 1:
The authentication system segments the authentication process into multiple independent components: visual story generation, image selection, and gaze tracking verification. Each component contributes to security without compromising usability, as users simply view images and naturally follow their gaze path while impostors cannot replicate the coordinated response
Solution Approach 2:
The patent replaces the mechanical text-based password input system with a visual image selection system enhanced by gaze tracking. This substitution eliminates the vulnerability of text passwords while maintaining ease of use through intuitive visual interaction, where users select images related to a displayed story
2Reliability
If long and complicated passwords are used to improve security, then the security is improved, but the ease of use deteriorates
Solution Approach 1:
The authentication system dynamically generates visual stories and image sets for each authentication attempt, making the challenge adaptive and unpredictable. Users interact with dynamic visual content rather than static passwords, achieving high security through variability while maintaining ease of use through natural image selection and gaze following
Solution Approach 2:
The patent substitutes the mechanical act of typing complex passwords with a visual interaction paradigm where users view a story and select relevant images. This replacement eliminates the burden of memorizing complicated passwords while achieving superior security through the combination of visual recognition and gaze tracking
3Device complexity
If traditional password authentication is used, then the device complexity is low, but the authentication security is insufficient
Solution Approach 1:
The patent merges multiple authentication mechanisms into a unified system: visual story presentation, image selection interface, and gaze tracking analysis work together synergistically. This combination achieves robust authentication security while keeping the overall system complexity manageable through integrated design where components support rather than complicate each other
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
Provides robust and secure user authentication by utilizing information users already know, preventing impostors from replicating authentication responses, and adding an additional layer of security through gaze tracking, making it difficult for observers to determine selected images.
Implementation Method 1
a gaze tracker for detecting a gaze path of the subject as the subject views the display
Data Source
AI summary
Method, system and media for authenticating a subject as a user. Embodiments generate visual stories specific to the user and for which the subject must select the corresponding images from among a plurality of decoy images. Gaze tracking can be used to determine which images the user has selected without allowing an observer to learn which images have been selected. Images for the visual story can be retrieved from the user's social networking profile, and corresponding text storied generated to indicate which images should be selected. Multiple security levels are possible by varying the number of story images and decoy images.
