BLE Device Function-Specific Authentication Index Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth Low Energy (BLE) communication lacks standardized access control for personal data, leading to potential unauthorized access and data leakage, as existing methods only ensure device pairing and connection security without managing data access rights.
Innovation Solution
An electronic device with a communication module, memory, and processor configured to receive and store authentication information for each function from an external device, transmitting authentication indices to manage data access rights on a per-function basis, ensuring secure data access and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device-to-device authentication is performed by Bluetooth pairing, then connection security is established, but data access control is not provided leading to potential data leakage
Solution Approach 1:
The patent segments data access control by creating function-specific authentication information for different applications and services. Each function receives tailored authentication credentials that limit access to only the data necessary for that specific function, preventing broad unauthorized access while maintaining connection security.
Solution Approach 2:
The patent implements local quality by providing differentiated access rights for different functions within the same device. Each application or service receives customized authentication information with specific access rights tailored to its functional requirements, ensuring that no single function can access all data regardless of connection security.
2Adaptability or versatility
If personal data is linked to external device based on BLE, then data transmission is enabled, but access control is not provided allowing unauthorized access
Solution Approach 1:
The patent applies preliminary action by pre-distributing function-specific authentication information to multiple applications and services before data transmission occurs. This ensures that even if data is linked to external devices, only authorized functions with appropriate credentials can access specific data, preventing unauthorized access while enabling legitimate transmission.
Solution Approach 2:
The patent introduces function-specific authentication information as an intermediary layer between data and external device access. This intermediary mechanism verifies and controls which functions can access which data, enabling adaptable data transmission while maintaining security through credential-based authorization.
3Reliability
If authentication information is stored for each function, then data access control is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by using a standardized authentication information structure that can serve multiple functions and applications. The same authentication framework and data structures are reused across different functions, reducing the need for separate complex systems for each application while maintaining granular access control.

AI summary
According to an embodiment, an electronic device may include: a communication module comprising communication circuitry configured to operate in Bluetooth low energy (BLE), a memory, and at least one processor operatively coupled to the communication module and the memory. The at least one processor may be configured to: receive authentication information about each function from an external electronic device via BLE, the authentication information about each function including information about data for the function and information about an access right level of the function, store the received authentication information about each function in the memory, and control the communication module to transmit an authentication index of each function corresponding to the authentication information about the function to the external electronic device by BLE.
