Secure Camera Mode for Augmented Reality in Restricted Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In secure areas like manufacturing facilities, the use of cameras is often restricted or banned, which prevents augmented reality applications from functioning effectively since turning off the camera renders these applications inoperable.
Innovation Solution
Implementing a secure camera mode that protects images captured by the camera through encryption and a protected audio visual path, allowing augmented reality applications to function while ensuring that images are not saved in clear memory or accessed without proper authentication, enabling the camera to remain on and operate within secure areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is turned off to comply with security restrictions in protected areas, then security requirements are met, but augmented reality applications become inoperable
Solution Approach 1:
The system segments the camera operation into different modes: normal mode for general use and secure mode for protected areas. In secure mode, the camera remains operational but with restricted access to captured images, allowing AR functionality while maintaining security compliance
Solution Approach 2:
A protected audio visual path (PAVP) acts as an intermediary between the camera and the rest of the system. The PAVP enables image data to be transmitted and processed while maintaining security restrictions, allowing AR applications to function without compromising security
2Ease of operation
If the camera remains on to enable augmented reality applications, then application functionality is maintained, but security restrictions in protected areas are violated
Solution Approach 1:
The system applies different access qualities to camera data based on location. In protected areas, image data is protected through encryption and access restrictions, while still allowing the camera to capture and transmit data for AR processing
Solution Approach 2:
The system changes the security parameters of camera data based on location detection. When entering a protected area, the system transitions to secure mode with encrypted data handling and restricted access parameters, while maintaining camera functionality
3Reliability
If image data is protected through encryption and restricted access, then security is enhanced, but image processing and augmented reality functionality are compromised
Solution Approach 1:
The protected audio visual path (PAVP) serves as a secure intermediary that enables image processing while maintaining encryption. The PAVP allows authenticated access to processed images without exposing raw image data, maintaining both security and processing capability
Solution Approach 2:
The system works with encrypted copies of image data rather than the original unencrypted data. Processed images are generated from encrypted data and displayed through the protected path, allowing AR functionality without storing or accessing plain text image data

AI summary
An example system that allows a camera enabled application, such as an augmented reality application, to run in a protected area may include a first device including a camera, the camera including a secure mode of operation and a display, an image processing module configured to convert image data from the camera to encoded data when the camera is in the secure mode and protect image data stored in the system, an encryption module configured to encrypt encoded data from the image processing module, and a protected audiovisual path mechanism configured to securely send augmented encoded data to the display.
