Cloud-Authenticated Bluetooth Pairing for Automatic Device Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth systems lack automatic authentication for pairing with new devices and integrated synchronization methods for media recording across multiple devices, leading to inefficiencies in power consumption and audio data transmission/reception, particularly in complex topologies like 5.1 channel environments.
Innovation Solution
Implementing an account-based pairing method through a seeker device obtaining credential information from a server, using a hash value to establish connections, and integrating synchronization methods for media recording across multiple devices.
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 for new devices is not provided and power consumption increases
Solution Approach 1:
The patent implements preliminary action by pre-registering device information and credentials in a cloud server before actual pairing. When a seeker device wants to connect to a provider device, the authentication credentials are already prepared and stored in the cloud, eliminating the need for real-time authentication negotiations and reducing power consumption during the pairing process.
Solution Approach 2:
The patent introduces a cloud server as an intermediary that mediates the authentication process between seeker and provider devices. The cloud server stores credential information and verifies device identities, allowing automatic authentication without direct communication between the pairing devices, thus reducing their power consumption.
2Reliability
If conventional Bluetooth pairing method is used, then device connection can be established, but integrated synchronization in media recording is not provided
Solution Approach 1:
The patent implements universality by creating a multi-functional pairing system that simultaneously handles device authentication, credential verification, and media recording synchronization. The cloud-based credential system serves multiple purposes: securing device connections and providing timing reference information for synchronized media recording across multiple devices.
Solution Approach 2:
The patent implements feedback mechanisms where the cloud server provides synchronization timing information back to connected devices based on their credential verification results. This feedback loop enables integrated synchronization in media recording by allowing devices to adjust their recording timing based on centralized timing references obtained through the credential authentication process.
3Ease of operation
If cloud authentication is implemented, then automatic authentication is provided, but device complexity increases
Solution Approach 1:
The patent applies the extraction principle by removing the complex authentication logic from the end devices and relocating it to a cloud server. The seeker and provider devices only need to perform simple credential retrieval and verification operations, while the heavy lifting of authentication management, credential storage, and security verification is extracted and handled by the cloud infrastructure.

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.
