User Terminal Screen Capture for Secure XR Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a secure and simple communication connection system between user terminals, particularly in the context of Extended Reality (XR) devices that frequently communicate with other user terminals, ensuring secure access and authentication.
Innovation Solution
A user terminal equipped with a camera to photograph the screen of an external terminal, transmit image information to a management server for authentication, and establish a secure connection based on approved access information, utilizing Bluetooth Low Energy (BLE) and image recognition to manage connections with multiple external terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual authentication and connection establishment procedures are used between user terminals, then security can be maintained, but the complexity of operation and time consumption increase significantly
Solution Approach 1:
The system enables automatic authentication and connection establishment between user terminals through self-service mechanisms. The camera captures the other terminal's screen, extracts identification information, and automatically completes the connection process without requiring manual intervention, thus maintaining security while simplifying operation
Solution Approach 2:
The system performs preliminary actions by capturing and storing authentication information in advance. The camera takes a picture of the other terminal's screen which displays authentication codes or QR codes, and this pre-captured information is used to automatically establish the connection, eliminating the need for manual authentication steps
2Reliability
If traditional authentication methods are used between user terminals, then security protocols can be followed, but the connection process becomes time-consuming and complex
Solution Approach 1:
The system replaces manual mechanical authentication processes with automated optical recognition. Instead of manually entering codes or scanning QR codes physically, the camera automatically captures and processes authentication information from the other terminal's screen, substituting mechanical interaction with automated visual recognition and data processing
Solution Approach 2:
The system creates a visual copy of the authentication information by capturing the other terminal's screen through the camera. This copied image data is then processed to extract authentication credentials, allowing the system to replicate the authentication process remotely and automatically without physical contact or manual input
3Ease of operation
If automatic connection establishment is implemented, then convenience is improved, but security risks may increase due to automated access
Solution Approach 1:
The system incorporates feedback mechanisms where the captured screen information is analyzed and verified before automatic connection establishment. The authentication information obtained from the other terminal's screen is cross-checked and validated, ensuring that automatic access is granted only when proper authentication credentials are confirmed, thus maintaining security while enabling automation
