3D Virtual Space Passcode Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic device authentication methods are not secure, especially when a third party is present, as they lack adequate protection against unauthorized access.
Innovation Solution
A device uses 3D objects presented in virtual space, requiring user input in a specific sequence to authenticate, which can unlock a lock screen or encrypted storage, utilizing VR, AR, or MR technologies to enhance security by making the authentication process invisible to observers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional 2D authentication interface is used, then ease of operation is maintained, but security is compromised due to observability by third parties
Solution Approach 1:
The patent transitions from traditional 2D authentication interfaces to 3D virtual space authentication. Users interact with 3D objects positioned at different spatial coordinates and depths, requiring them to navigate and select objects in three-dimensional space rather than on a flat screen. This dimensional expansion makes authentication sequences invisible to observers while maintaining user accessibility through natural gestural interactions.
2Reliability
If 3D virtual space authentication is implemented, then security is improved by making authentication invisible to observers, but device complexity increases
Solution Approach 1:
The patent employs universal gestural controls that can be performed with hands or other body parts, making the 3D authentication system accessible to various users regardless of their specific physical capabilities. The same gesture set works for selecting different 3D objects, confirming selections, and navigating the virtual space, simplifying the learning curve and improving ease of operation despite the added dimensional complexity.
3Reliability
If multiple 3D objects at different virtual depths are used, then security against shoulder surfing is enhanced, but measurement and detection difficulty increases
Solution Approach 1:
The patent incorporates immediate visual and haptic feedback when users correctly select 3D objects in the authentication sequence. Selected objects provide distinct visual confirmation (such as highlighting or scaling) and haptic feedback through the haptic interface, allowing users to verify their selections in real-time. This feedback mechanism simplifies the detection and measurement of user inputs by providing clear, unambiguous signals that reduce detection errors.
Data Source
AI summary
In one aspect, a device includes a processor and storage accessible to the processor. The storage includes instructions executable by the processor to present, on a display and in virtual space, at least first and second three-dimensional (3D) objects to which user input is directable in a particular sequence to provide a passcode associated with the device. The instructions are also executable to identify receipt of the passcode based on detection of first user input directed in the particular sequence to the first and second 3D objects. The instructions are then executable to authenticate a user responsive to the identification. In various examples, the virtual space may form part of an augmented reality presentation, a mixed reality presentation, and/or a virtual reality presentation.
