Solution Overview

Problem

Conventional eye-movement authentication systems are vulnerable to password theft due to keylogging, as eye-movement paths can be recorded, allowing unauthorized access to displayed passwords.

Innovation Solution

A dynamic graphic eye-movement authentication system using an image capturing device, display device, and control unit that captures eye movements and gaze direction to generate authentication-oriented input information through dynamic graphics, reducing the risk of password inference by keylogging devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional eye-movement authentication is used to enter passwords, then user authentication capability is improved, but security against keylogging attacks deteriorates because eye-movement paths can be recorded

Engineering Contradiction:

Improveauthentication capabilityVSAvoidsecurity against keylogging

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies dynamics by making the graphic elements move continuously on the display screen. The moving graphics change positions dynamically, so that even if a keylogging device records eye-movement paths, the recorded paths cannot be used to infer passwords because the graphic positions are constantly changing. This resolves the security vulnerability of static eye-movement authentication.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of graphic position from static to dynamic. By continuously changing the positions of graphics on the screen, the system ensures that recorded eye-movement data becomes invalid over time, thereby preventing password inference attacks while maintaining authentication functionality.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If static graphics are used for eye-movement authentication, then system simplicity is improved, but security deteriorates because password paths can be recorded and replayed

Engineering Contradiction:

Improvesystem simplicityVSAvoidpassword security

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent transforms static graphics into dynamic moving graphics. The graphics continuously change positions on the display screen, which prevents recording and replay attacks while maintaining relatively simple system architecture. This resolves the contradiction between system simplicity and password security.

Inventive Principle:

Principle #15Dynamics

3Reliability

If dynamic graphics are used for eye-movement authentication, then security against password theft is improved, but device complexity increases due to additional motion control mechanisms

Engineering Contradiction:

Improvepassword securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic graphics through software-controlled motion of display elements. The control unit generates moving graphics that change positions according to predetermined patterns, providing security against password theft while avoiding complex hardware modifications. This resolves the contradiction between enhanced security and system complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent replaces potential mechanical motion systems with software-based graphic rendering. Instead of physically moving objects, the system uses digital graphics that change positions through software control, achieving dynamic behavior with minimal hardware complexity while maintaining high security standards.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If eye-movement tracking is implemented to prevent password theft, then security is improved, but ease of operation deteriorates due to additional tracking apparatus

Engineering Contradiction:

ImprovesecurityVSAvoiduser operation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces complex eye-movement tracking apparatus with software-based graphic motion. Instead of actively tracking user eye movements with specialized hardware, the system passively moves graphics in predictable patterns, maintaining security while simplifying the user experience and reducing hardware requirements.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
