3D Virtual Object Authentication in Alternative Reality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Alternative reality software applications lack robust user authentication methods, making them vulnerable to unauthorized access, as existing methods rely on simple interfaces and do not effectively account for user movement, gaze, or position during authentication.
Innovation Solution
A system that generates a multidimensional authentication credential based on user interactions with 3D objects in a virtual environment, including positioning, interaction, visual alterations, movement, and gaze, which is stored and compared to authenticate users, incorporating real-world physics rules for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple authentication methods (password entry via virtual keyboard or straightforward gestures) are used in alternative reality applications, then ease of operation is improved, but security is worsened because passwords are susceptible to being stolen by onlookers who can match user movements or deduce key presses
Solution Approach 1:
The patent transitions authentication from 2D virtual keyboard/gesture interfaces to 3D physical object manipulation in the alternative reality environment. Users physically handle three-dimensional objects with multiple degrees of freedom, adding spatial dimensionality to the authentication process. This makes observation and replication by onlookers significantly more difficult while maintaining usability.
Solution Approach 2:
The patent introduces physical three-dimensional objects as intermediaries between the user and the authentication system. These objects serve as a mediator that captures complex user interactions (grasping, manipulating, positioning) which are then translated into authentication credentials. This intermediary layer obscures the actual authentication mechanism from onlookers.
2Reliability
If complex multi-faceted user authentication mechanisms are implemented in alternative reality applications, then authentication security is improved, but device complexity is worsened
Solution Approach 1:
The system automatically captures user interactions with 3D objects and generates authentication credentials without requiring separate authentication logic or complex verification processes. The authentication mechanism leverages the natural interaction data already collected during object manipulation, making the system self-sufficient and reducing overall complexity.
Solution Approach 2:
The same 3D object manipulation interface serves dual purposes: both as the primary user interaction mechanism for application functionality and as the authentication mechanism. This multi-functionality eliminates the need for separate authentication hardware or complex authentication protocols, reducing system complexity while maintaining security.
3Ease of operation
If simplistic object selection techniques are used for user authentication in alternative reality environments, then ease of operation is improved, but authentication security is worsened because objects do not interact with each other, appear as real-world objects, move to different locations, and change appearance during authentication
Solution Approach 1:
The patent implements dynamic 3D objects that can interact with each other, change positions, and alter appearances during the authentication process. These objects respond to user actions in realistic ways, creating a dynamic authentication sequence that is difficult to predict or replicate. The objects' behaviors are governed by physics-based rules that add complexity to the authentication pattern while maintaining natural interaction.

AI summary
Methods and apparatuses are described for user authentication in a three-dimensional (3D) alternative reality software application. A computing device coupled to an alternative reality viewing device generates a 3D virtual environment for display in the alternative reality viewing device, the 3D virtual environment comprising a plurality of 3D objects. The computing device identifies a subset of the plurality of 3D objects selected by the user of the alternative reality viewing device. The computing device captures a first set of actions of the user with respect to the subset of 3D objects, including recording a sequence of the first set of actions. The computing device generates a multidimensional authentication credential for the user based upon the first set of actions and stores the multidimensional authentication credential in a database.
