Multi-Terminal Bluetooth Lock Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic locks using Bluetooth technology for unlocking rely on a single unique identification data item, which compromises security, especially in situations requiring strict safety measures.
Innovation Solution
Implementing a system that requires two security communication terminals to transmit matching security data items to the electronic apparatus, ensuring the lock is only released when both terminals are near, enhancing security by eliminating single-point vulnerabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single unique identification data item is used for Bluetooth device authentication, then the ease of operation is improved, but the reliability of the electronic lock is worsened
Solution Approach 1:
The authentication system is segmented into multiple independent authentication units (first security communication terminal and second security communication terminal), each providing separate identification data items. This segmentation ensures that the electronic lock requires multiple authentication sources rather than relying on a single point of failure, thereby improving reliability while maintaining operational simplicity through automated multi-terminal verification.
2Reliability
If multiple security communication terminals are required for lock release, then the reliability is improved, but the device complexity is worsened
Solution Approach 1:
The electronic apparatus is designed with multi-functionality to handle multiple security communication terminals universally. The system can authenticate different types of terminals (smartphones, tablets, wearables) using the same Bluetooth authentication protocol, managing multiple terminals through a unified control framework that compares identification data items against registered values without requiring terminal-specific processing logic.
3Device complexity
If a single Bluetooth device is used for authentication, then the device complexity is reduced, but the security is worsened
Solution Approach 1:
The system implements beforehand cushioning by pre-registering identification data items from multiple security communication terminals before authentication is needed. This preparatory registration creates a buffer of verified authentication sources, cushioning the system against security threats by ensuring that even if one terminal is compromised, other pre-registered terminals can provide legitimate authentication, thereby enhancing security without adding complex real-time verification mechanisms.
Data Source
AI summary
According to one embodiment, an electronic apparatus has a communication circuitry, a memory and a processor. The circuitry communicates with terminals by short-distance wireless communication in accordance with a wireless communication standard. The memory stores first security data of a first terminal and second security data of a second terminal. The processor receives a command to lock or unlock an electronic locking, waits for any security data to be received from the terminals for a period after a reception of the command, accepts the command if the first and second security data is received for the period, and rejects the command if at least one of the first and second data is not received for the period.
