Bluetooth Authority Policy Segmentation for Secure Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth devices, especially those without user interfaces, face complexity in connection management and authentication due to the lack of standardized methods for differentiating user authorities and securely establishing connections using Bluetooth Low Energy (BLE) technology.
Innovation Solution
A method and apparatus for connecting devices using Bluetooth Low Energy (BLE) technology, which involves transmitting user information requests, registering devices based on user authentication, and establishing connections with specific authority policies, allowing for Admin or guest authentication and managing user access through virtual user information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth devices use standardized connection methods, then connection management becomes simpler, but user authority differentiation and security control become more complex
Solution Approach 1:
The patent segments user authorities into distinct levels (admin authority and guest authority) with clearly defined permissions. Admin authority allows full device control while guest authority provides limited access. This segmentation simplifies connection management by providing standardized roles while maintaining security through differentiated access levels.
Solution Approach 2:
The patent applies local quality by assigning different authority levels to different users connecting to the same device. Each user receives appropriate permissions based on their role (admin or guest), allowing the system to maintain both simplicity through standardization and security through localized authority differentiation.
2Measurement precision
If real user information is transmitted during Bluetooth connection, then authentication accuracy improves, but personal information security risks increase
Solution Approach 1:
The patent creates virtual user information as copies of real user identities for Bluetooth transmission. Instead of transmitting actual personal information, the system generates virtual identifiers that maintain authentication accuracy while protecting personal data security. The virtual information serves as a safe representation that preserves necessary authentication functionality without exposing sensitive real user data.
3Ease of operation
If Bluetooth connection process is simplified, then user convenience increases, but security authentication becomes weaker
Solution Approach 1:
The patent performs preliminary authentication actions by establishing authority policies and virtual user information before the actual Bluetooth connection is made. This preliminary setup enables the connection process to be simplified and faster, while security is maintained through the pre-configured authority levels and virtual identification systems that are ready before connection occurs.

AI summary
Disclosed is a method for connecting, by a first device, with a second device using Bluetooth communication. The method includes transmitting a request message to request user information for identifying a user of the second device to the second device, receiving a response message including the user information from the second device, registering the second device to a first authority policy or a second authority policy based on the user information, and establishing a Bluetooth connection with the second device registered to the first authority policy or the second authority policy. The first authority policy indicates a first control authority for controlling an operation of the first device, the second authority policy indicates a second control authority for controlling an operation of the first device, the first control authority indicates a control authority capable of controlling an operation of the first device within a limited range, the second control authority indicates a control authority capable of controlling all of operations of the first device.
