Augmented Reality Authentication Using Spatial Movement Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication methods, such as password entry and biometric scans, may be vulnerable to detection and can compromise security, especially in public settings where patterns of authentication can be observed.
Innovation Solution
The use of augmented reality features displayed on a display device, where users select virtual images in a predefined order using sensors like eye tracking and inertial motion sensors, allowing for secure authentication by varying the sequence and appearance of features between sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods (password entry, biometric scans) are used, then authentication can be performed, but security is compromised because patterns of authentication can be observed and detected by others in public settings
Solution Approach 1:
The patent transitions authentication from a 2D screen interaction to a 3D spatial experience using augmented reality. Virtual images are positioned at different locations in the physical space around the user, requiring head movements and spatial navigation to access. This dimensional change makes authentication patterns invisible to observers who can only see the screen, not the user's head movements through space.
Solution Approach 2:
The patent introduces augmented reality virtual images as an intermediary between the user and the authentication system. Instead of directly interacting with on-screen elements, users interact with virtual images overlaid in physical space. This intermediary layer conceals the actual authentication actions from observers, as they see only virtual elements floating in space, not the user's authentication pattern.
2Reliability
If augmented reality features are displayed for authentication, then security is enhanced by making patterns less detectable, but device complexity increases due to requirements for sensors and virtual image processing
Solution Approach 1:
The patent makes the display device's sensors serve dual purposes: they detect user head movements for authentication while also enabling augmented reality functionality. The same sensors that track user interaction with virtual images are used to verify authentication patterns, eliminating the need for separate authentication hardware and reducing overall device complexity.
Solution Approach 2:
The patent combines the authentication system with the augmented reality display system into a single integrated process. The virtual images serve both as the authentication interface and as the security mechanism itself. By merging these functions, the patent avoids adding separate complex authentication hardware while maintaining enhanced security.
3Object-affected harmful factors
If virtual images are displayed in three-dimensional space for authentication, then authentication patterns become less detectable to observers, but the difficulty of detecting and measuring user movements increases
Solution Approach 1:
The patent replaces mechanical observation methods with sensor-based detection. Instead of relying on visual observation of user interactions (which fails in 3D space), the system uses sensors to detect head movements and spatial navigation. This substitution enables accurate measurement of three-dimensional authentication patterns that would be impossible to detect through traditional visual means.

AI summary
Embodiments are disclosed that relate to authenticating a user of a display device. For example, one disclosed embodiment includes displaying one or more virtual images on the display device, wherein the one or more virtual images include a set of augmented reality features. The method further includes identifying one or more movements of the user via data received from a sensor of the display device, and comparing the identified movements of the user to a predefined set of authentication information for the user that links user authentication to a predefined order of the augmented reality features. If the identified movements indicate that the user selected the augmented reality features in the predefined order, then the user is authenticated, and if the identified movements indicate that the user did not select the augmented reality features in the predefined order, then the user is not authenticated.
