3D Virtual Environment Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods, such as alphanumeric and graphical passwords, are cumbersome to remember, prone to being forgotten, and vulnerable to security attacks like shoulder-surfing, necessitating a more effective and secure authentication method.
Innovation Solution
An interactive three-dimensional authentication system that displays a virtual environment, allowing users to navigate and interact within it to define a passcode, leveraging psychological principles like spatial and episodic memory, and physical depth cues for enhanced usability and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alphanumeric passwords are used for authentication, then security can be improved through complexity, but usability deteriorates due to difficulty in remembering and inputting
Solution Approach 1:
The patent transitions from traditional 2D alphanumeric passwords to a 3D spatial authentication system. Users navigate through a three-dimensional virtual environment, manipulating objects and moving through space to create passcodes. This dimensional shift allows authentication to leverage spatial memory and motor skills, making passcodes more memorable and easier to input while maintaining security through the complexity of 3D navigation paths and object interactions.
2Reliability
If alphanumeric passwords are made longer and more complex to improve security, then authentication security is improved, but memorability deteriorates
Solution Approach 1:
By moving to 3D space, the system encodes authentication information spatially rather than linearly. Users remember locations, orientations, and spatial relationships within a virtual environment, which leverages the brain's superior spatial memory capabilities compared to verbal or visual memory of character sequences.
Solution Approach 2:
The patent replaces the mechanical act of typing alphanumeric characters with spatial manipulation and navigation. Users interact with 3D objects through gestures, movements, and spatial positioning, substituting motor skills and spatial reasoning for memorizing complex character sequences.
3Loss of information
If graphical passwords are used instead of alphanumeric passwords, then memorability is improved, but security deteriorates due to vulnerability to shoulder-surfing attacks
Solution Approach 1:
The system moves from 2D graphical passwords to 3D spatial authentication. Instead of selecting images on a flat screen, users navigate through a three-dimensional virtual environment, creating authentication sequences that involve spatial movement and object manipulation. This 3D complexity makes shoulder-surfing attacks significantly more difficult while maintaining memorability through spatial relationships.

AI summary
An authentication method and system, includes a display to present interactive three-dimensional (3D) virtual environments. The manner or sequence in which a user interacts with objects in the interactive 3D environment is used to form their passcode. The entered passcode is then compared with a previously stored or “set” passcode to determine whether the user is authenticated and permitted to access content controlled by the authentication process.
