Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods in virtual environments, such as gesture-based or PIN-based systems, are inefficient and vulnerable to visual attacks, lacking a secure and convenient way to authenticate users.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gesture-based or PIN-based authentication is used in virtual environment, then authentication functionality is provided, but security is compromised due to vulnerability to visual attacks
Solution Approach 1:
The patent replaces traditional visual-based authentication mechanisms (PIN entry, pattern drawing) with behavioral biometric analysis. Sensors capture physiological and behavioral data (eye movements, head movements, reaction patterns, tactile responses) that are processed to authenticate users. This substitution eliminates the visual attack vulnerability inherent in traditional methods while maintaining authentication functionality.
Solution Approach 2:
The patent introduces behavioral biometric data as an intermediary between the user and the authentication system. Instead of directly entering credentials that can be visually observed, the system captures intermediate behavioral signals (eye tracking data, head movement patterns, reaction times) that indirectly verify user identity. This intermediary layer prevents direct visual attacks on authentication credentials.
2Reliability
If PIN or pattern entry is performed in virtual environment, then authentication is achieved, but user convenience deteriorates due to challenging interaction
Solution Approach 1:
The patent enables the authentication system to automatically capture and analyze behavioral data without requiring active user participation in the authentication process. Sensors continuously monitor eye movements, head movements, and reaction patterns during normal virtual environment interaction. The system self-processes this data to authenticate users, eliminating the need for manual PIN entry or pattern drawing and thereby improving convenience while maintaining security.
Solution Approach 2:
The patent performs preliminary data collection during normal user interaction with the virtual environment. Behavioral biometric data (eye movements, head movements, reaction patterns) is captured continuously during routine tasks before authentication is actually needed. This preliminary action stores behavioral patterns that can be quickly verified during authentication, making the process both convenient and secure.
3Device complexity
If traditional authentication methods are used, then authentication process is simple, but security efficiency is poor
Solution Approach 1:
The patent makes the sensor system multi-functional by using the same sensors to capture both behavioral data for authentication and operational data for system optimization. The eye tracking sensors, for example, serve dual purposes: monitoring user behavior patterns for biometric authentication and tracking user focus for virtual environment navigation. This universality maintains simplicity while enhancing security efficiency.
Solution Approach 2:
The patent changes the authentication parameters from static credentials (PINs, patterns) to dynamic behavioral parameters (reaction times, movement patterns, physiological responses). These parameter changes enable more sophisticated security analysis while maintaining a simple user interface. The system analyzes multiple behavioral parameters simultaneously to achieve high security efficiency without complicating the user experience.
Data Source
AI summary
A method including: capturing or receiving data associated with behavior of a user of a virtual reality device during a session in a virtual environment, wherein the data includes sensory inputs associated with the user from one or more sensors and information associated with user parameters; initiating authentication of the user in the virtual environment; comparing the captured or received data with historic data of the user, wherein the historic data is associated with behavior of the user monitored for a plurality of sessions over a period of time in the virtual environment; determining a score based on the comparison; comparing the score with a predefined threshold score; and in response to determining that the score is above the predefined threshold score, authenticating the user.
