Cloud-Authenticated Bluetooth Pairing for Low-Delay Multi-Device Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth systems lack methods for automatic authentication in pairing with new devices and integrated synchronization of media recording across multiple devices, particularly in complex topologies such as 5.1 channel environments, leading to increased power consumption and synchronization delays.
Innovation Solution
Implementing an account-based pairing method that involves obtaining credential information from a server, using a hash value to establish connections, and synchronizing media across devices through a cloud-authenticated pairing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional Bluetooth pairing method is used, then device connection can be established, but automatic authentication is not available and power consumption increases
Solution Approach 1:
The patent implements preliminary action by pre-registering device credential information (device ID, public key, or device fingerprint) in a cloud server before actual pairing occurs. When pairing is needed, the seeker device automatically retrieves pre-stored credential information from the cloud server to authenticate the provider device, eliminating the need for manual authentication and reducing power consumption from continuous scanning and authentication attempts.
2Extent of automation
If cloud authentication is implemented, then automatic pairing is enabled, but system complexity increases
Solution Approach 1:
The patent uses a cloud server as an intermediary to manage credential information storage and retrieval. The seeker device stores credential information (device ID, public key, or device fingerprint) in the cloud server during initial device setup. During pairing, the seeker device simply queries the cloud server for the provider device's credentials and performs authentication locally, offloading the complex credential management to the cloud intermediary while keeping the local system relatively simple.
3Adaptability or versatility
If multiple Bluetooth devices are connected, then audio data transmission is enabled, but synchronization delay increases
Solution Approach 1:
The patent implements preliminary action by pre-establishing credential information in the cloud server for multiple devices before audio transmission begins. This allows seeker devices to quickly authenticate and join audio groups without time-consuming manual pairing processes, reducing synchronization delays when multiple devices need to connect for audio data transmission in topologies like 5.1 channel environments.

AI summary
The present disclosure relates to a method, device and computer program for cloud-authenticated pairing in a wireless communication system, and a recording medium therefor. A method for carrying out account-based pairing in a wireless communication system, according to one embodiment of the present disclosure, may comprise the steps in which: a seeker device acquires credential information of a provider device from a server; the seeker device acquires, from the provider device, an advertising packet comprising a hash value which is based on the credential information; and the seeker device establishes a connection with the provider device on the basis of the acquired credential information and the hash value which is based on the acquired credential information.
