Display Device ID Pairing for Secure Wireless Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multiple-to-multiple wireless connection environments, users face challenges in securely connecting their information terminals to desired display devices without the need for cumbersome authentication input, particularly when many devices are within range, leading to security and resource issues.
Innovation Solution
A wireless connection system where display devices display device ID information or coded images for authentication, allowing information terminals to read and confirm matching IDs, thereby establishing secure connections without manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication ID input is required for wireless connection, then security is improved, but ease of operation deteriorates due to limited input means in information terminals
Solution Approach 1:
The patent replaces the mechanical input method (keyboard, touch panel) with an optical recognition method (camera-based code reading). The information terminal captures an authentication code displayed on the display device and automatically extracts authentication information, eliminating the need for manual input while maintaining security.
Solution Approach 2:
The patent introduces an authentication code as an intermediary element between the display device and information terminal. The code serves as a medium that carries authentication information in a visually presentable form, allowing automatic recognition and verification without direct input from the user.
2Measurement precision
If manual authentication input is required, then connection accuracy is improved, but loss of time increases due to cumbersome input operations
Solution Approach 1:
The display device prepares and displays the authentication code in advance before the connection process begins. The code contains pre-configured authentication information that is automatically recognized by the information terminal, eliminating the need for real-time input operations during the connection process.
Solution Approach 2:
The patent replaces time-consuming manual input operations with rapid optical recognition. The camera-based code reading process automatically extracts authentication information in seconds, significantly reducing the time required compared to manual keyboard or touch panel input.
3Reliability
If authentication is implemented in multiple-to-multiple wireless connection environment, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The patent uses a visual copy (authentication code) of the authentication information that can be displayed and read. Instead of implementing complex authentication protocols directly in the information terminal, the system creates a visual representation that can be easily captured and processed, simplifying the overall system complexity.
Data Source
AI summary
A wireless connection system executes wireless connection between an information terminal of a user and a display device installed in environment. In a case where an information terminal existing in the vicinity thereof is detected, the display device displays device ID information related to authentication for wireless connection with the detected information terminal (or an image obtained by coding it) on a display screen. The information terminal confirms whether the device ID information read from the display screen match device ID information of an own device or not, and establishes wireless connection using an authentication ID for wireless connection with the display device after matching is confirmed. The display device establishes wireless connection with the information terminal using an authentication ID.
