Secure Wireless Pairing via Visual Code Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth communication technology faces challenges with device discovery, passkey generation and transfer, and low signal strength, leading to unreliable connections and data transfer issues, especially with short range and low power data transfers.
Innovation Solution
A method and system for secure wireless communication using a framework that broadcasts universally unique identifiers (UUIDs) and employs picture pairing to establish connections between devices, allowing for authentication and data transfer over a wireless network, independent of device type and operating system, with minimal human interaction and error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth passkey authentication is used, then device connection is established, but connection reliability deteriorates due to passkey generation and transfer errors
Solution Approach 1:
The patent replaces the manual mechanical process of passkey generation, transfer, and entry with an automated optical recognition system. The source device displays a visual code (QR code or image), and the target device's camera captures and automatically decodes it, eliminating the manual typing process that causes errors and improving both reliability and ease of operation.
Solution Approach 2:
The patent creates a visual copy (image or QR code) of the authentication credentials on the source device screen. Instead of transferring passkeys through vulnerable wireless channels or manual entry, the system generates a visual representation that can be captured by the target device's camera, providing a more reliable and user-friendly authentication method.
2Adaptability or versatility
If Bluetooth device discovery is used, then devices can be found for connection, but discovery effectiveness deteriorates due to short range limitations
Solution Approach 1:
The patent makes the visual code display function universal across different device types and operating systems. Any device with a display and camera can participate in the authentication process regardless of its specific platform, thereby improving adaptability while maintaining the extended range benefits of visual code transmission.
3Use of energy by moving object
If low power Bluetooth transmission is used, then energy consumption is reduced, but signal strength deteriorates leading to connection problems
Solution Approach 1:
The patent performs the authentication information transfer through visual codes before establishing the low-power Bluetooth connection. The visual code transmission occurs during the pairing phase when higher power is acceptable, allowing the subsequent data transfer to utilize energy-efficient Bluetooth low power mode without compromising connection reliability.
Data Source
AI summary
A system and method for secure wireless communication for transferring or sharing data between at least two devices over a wireless network. A set of pictures are displayed on a source device from which a picture is selected either manually by a user or automatically by the system. Information related to the selected picture is transmitted to a target device. A set of pictures are displayed on the target device. On the target device, a particular picture is selected either manually by a user of the target device or automatically by the system, and further transmitted back to the source device. At the source device, the picture received from the target device is matched with the selected picture previously transmitted by the source device. Upon a successful match, the source device transmits an authentication confirmation for pairing the source device and the target device and enables data transfer.
