AR User Authentication with Virtual Object Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication methods in augmented reality environments are inadequate, particularly when authentication objects are unavailable, leading to inefficiencies and potential security vulnerabilities.
Innovation Solution
An electronic device generates additional virtual objects to replace unavailable authentication objects, allowing users to select these objects as part of a registered sequence for successful authentication, using sensors to gather spatial information and a processor to manage the output and determination of successful authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual objects are generated to replace unavailable authentication objects, then authentication reliability is improved, but device complexity increases
Solution Approach 1:
The system creates virtual copies of authentication objects when physical objects are unavailable. The processor generates virtual object data that replicates the functional characteristics of missing authentication objects, allowing users to interact with these virtual representations through the display device. This copying mechanism ensures authentication continuity without requiring complex hardware modifications.
Solution Approach 2:
The system introduces an intermediary layer between the user and the authentication system. When physical authentication objects are unavailable, the processor acts as an intermediary by generating and managing virtual object representations. This intermediary mechanism mediates the authentication process, allowing it to proceed reliably even when direct physical interaction is impossible.
2Reliability
If multiple virtual objects are generated for unavailable authentication objects, then authentication security is improved, but information processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-generating virtual object data and storing it in memory before authentication is actually needed. When physical authentication objects become unavailable, the processor can quickly retrieve and deploy the pre-prepared virtual objects without requiring time-consuming generation processes during the critical authentication moment.
Solution Approach 2:
The system generates a greater number of virtual objects than the minimum required to replace unavailable authentication objects. This excessive action provides multiple potential authentication targets, enhancing security by making it harder for unauthorized users to guess the correct object. The additional virtual objects are generated and presented to the user, with the system validating selections against the registered authentication sequence.

AI summary
An electronic device is provided. The electronic device obtains current spatial information on a physical space where a user is positioned using a sensor, generates a greater number of virtual objects than the number of unavailable authentication objects based on at least one authentication object among a plurality of authentication objects being unavailable in the current spatial information, outputs the generated virtual objects to a plurality of positions including a physical position of an unavailable authentication object, and determines that authentication is successful based on a user input that selects a generated virtual object and an available authentication object as a registered sequence.
