AR Device Location Authentication via Camera Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication techniques for augmented reality (AR) devices are insecure and inadequate, as many AR devices lack traditional input/output devices like keyboards and may not have GPS capabilities, making geofencing ineffective.
Innovation Solution
An AR device equipped with a camera that recognizes geographic location features, such as registered geometric shapes and objects, to authenticate and permit use only in authorized locations, combining this location recognition with user-specific authentication methods like PINs or biometrics for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication techniques (keyboard, GPS) are used, then authentication security is improved, but device compatibility is worsened because many AR devices lack these components
Solution Approach 1:
The patent replaces mechanical input devices (keyboard, GPS hardware) with an optical system using a camera to capture images of physical location markers. The camera captures visual information which is then processed to determine device location and authenticate usage, eliminating the need for physical keyboards or GPS receivers.
Solution Approach 2:
The patent introduces physical location markers as intermediary objects between the AR device and the authentication system. These markers serve as mediators that the camera can detect to determine location, bridging the gap between visual input capabilities and location-based authentication requirements.
2Reliability
If geofencing with GPS is implemented, then location-based access control is improved, but applicability is worsened since many AR devices lack GPS capability
Solution Approach 1:
The patent substitutes GPS satellite-based positioning with a camera-based visual recognition system that identifies physical location markers in the environment. This replacement enables location determination on devices without GPS receivers, expanding applicability to various AR hardware configurations.
3Adaptability or versatility
If camera-based location recognition is implemented, then device compatibility is improved, but authentication security is worsened compared to multi-factor authentication
Solution Approach 1:
The patent merges camera-based location recognition with traditional user-specific authentication methods (passwords, biometrics) into a unified two-factor authentication system. The location verification through camera-based marker recognition combines with user identity verification to create enhanced security that is more robust than either method alone.
Solution Approach 2:
The patent creates a universal authentication framework that can accommodate multiple authentication methods (visual location recognition, passwords, biometrics) within a single system. This multi-functional approach allows the system to adapt to different security requirements while maintaining a consistent user experience across various device types.

AI summary
In one aspect, a device may include at least one processor, a camera accessible to the at least one processor, and storage accessible to the at least one processor. The storage may include instructions executable by the at least one processor to receive input from the camera and to, based on the input, recognize a particular location. The instructions may also be executable to, based on the recognition of the particular location, permit use of a device.
