Bluetooth Device Permission Segmentation for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth devices lack security features, allowing unauthorized access and misuse, especially when lost, due to the absence of use and management permission controls, leading to potential information leakage.
Innovation Solution
A control method and system where a second device, such as a smartphone, establishes a pairing connection with a first device, like a vehicle-mounted device, and sends messages to manage permissions, enabling secure sharing and controlling the first device's pairing functions to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth devices allow simple operations to enter pairing mode, then ease of operation is improved, but security deteriorates as any user can reset and access the device
Solution Approach 1:
The patent segments device access rights by introducing two distinct permission levels: use permission (basic operations) and management permission (pairing control). This segmentation allows the device to be easily operated by users with use permission while protecting pairing functionality from unauthorized access through management permission requirements.
Solution Approach 2:
The patent introduces a management device as an intermediary between users and the Bluetooth device's pairing function. The management device holds management permission and must approve pairing operations, acting as a mediator that prevents direct unauthorized access while allowing legitimate operations to proceed through the established permission hierarchy.
2Adaptability or versatility
If Bluetooth devices allow any user to reset and enter pairing mode, then adaptability is improved, but loss of information worsens due to unauthorized access
Solution Approach 1:
The patent segments access control into two distinct permission levels: use permission for basic operations and management permission for pairing control. This segmentation enables multiple users to adaptively access the device for normal operations while preventing unauthorized pairing that could lead to information loss, as pairing actions require management permission.
Solution Approach 2:
The patent applies preliminary anti-action by requiring pre-established management permission before allowing pairing operations. The management device is configured in advance with management permission, and this permission is checked before any pairing action can occur, preventing unauthorized access that could result in information loss while still allowing adaptable usage.
3Device complexity
If Bluetooth devices lack permission management, then device complexity is reduced, but security deteriorates allowing unauthorized control
Solution Approach 1:
The patent segments the permission system into two distinct levels: use permission for basic operations and management permission for pairing control. This segmentation provides security through differentiated access control while maintaining relatively simple device complexity, as the permission structure is straightforward and easy to implement without requiring complex multi-level authorization systems.

AI summary
In a sharing method, a first device establishes a pairing connection to a second device. The second device and the first device exchange information with each other, so that the second device controls the first device. On a basis that the second device controls the first device, the second device shares the first device with a third device, and further a sharing connection is established between the first device and the third device, so that the third device uses or manages the first device
