Dual-Interface Communication Beacon for Secure Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beacons using the Bluetooth protocol face security issues due to its inherent insecurity and susceptibility to data interception, and they lack secure programming capabilities for multiple communication protocols.
Innovation Solution
A communication beacon with dual interfaces, one using a near-field communication (NFC) protocol for secure configuration and data reception, and another using a Bluetooth protocol for longer-range data transmission, ensuring secure data exchange and compatibility with multiple mobile terminals.

1Length of stationary object
If Bluetooth protocol is used for data transmission, then communication range is improved (greater than 1 meter), but security is worsened (susceptible to interception and unauthorized access)
Solution Approach 1:
The communication beacon is segmented into two distinct interface units: a first interface unit using NFC protocol for secure configuration and programming, and a second interface unit using Bluetooth protocol for data transmission. This segmentation allows each interface to be optimized for its specific function - NFC for security-critical operations with limited range, and Bluetooth for wide-area data communication.
Solution Approach 2:
The NFC interface unit acts as an intermediary that establishes secure configuration before Bluetooth communication begins. The NFC interface receives and processes configuration data including security credentials, then enables the Bluetooth interface to operate securely. This intermediary approach ensures that Bluetooth communication is preceded by secure authentication and configuration.
2Device complexity
If single interface with Bluetooth protocol is used, then device complexity is reduced, but security is worsened (inherent insecurity of Bluetooth)
Solution Approach 1:
The communication beacon is designed with multi-functionality by incorporating two interface units that serve different purposes. The first interface unit (NFC) handles configuration, programming, and security credential establishment, while the second interface unit (Bluetooth) handles data transmission. This multi-functional design allows the system to leverage the strengths of both protocols without requiring separate devices.
3Reliability
If NFC protocol is used for configuration, then security is improved (shorter range prevents interception), but communication range is worsened (less than 1 meter)
Solution Approach 1:
The communication beacon is segmented into two distinct interface units: a first interface unit using NFC protocol for secure configuration and programming, and a second interface unit using Bluetooth protocol for data transmission. This segmentation allows each interface to be optimized for its specific function - NFC for security-critical operations with limited range, and Bluetooth for wide-area data communication.
