Electronic Locking Device Dual Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic locking devices face security issues due to unauthorized access when authentication information is leaked, as they rely solely on single authentication methods, lacking robust dual authentication mechanisms.
Innovation Solution
A dual authentication system using an electronic key that performs wireless communication with a mobile terminal, combining UID data and encoding data authentication to securely unlock the device, including a receiving unit, authentication unit, and command unit for secure dual authentication and logging of authentication events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If single authentication method is used in electronic locking device, then ease of operation is improved, but security is deteriorated due to unauthorized access when authentication information is leaked
Solution Approach 1:
The authentication process is divided into two separate authentication methods: first authentication based on authentication information (password, fingerprint, etc.) and second authentication based on encoding data generated by button input. Both authentication results must be successful for the door to unlock, creating a segmented multi-layer security system that maintains ease of use while significantly improving security.
2Reliability
If dual authentication is implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The control unit integrates both authentication processes (first authentication based on authentication information and second authentication based on encoding data) into a single unified control mechanism. The control unit receives results from both authentication methods and makes the final unlock decision based on the combination of both results, merging the dual authentication processes into one cohesive system that improves security without requiring separate independent systems.
3Reliability
If mechanical locking device is used, then security is improved through physical key control, but ease of operation is worsened due to key loss and replacement needs
Solution Approach 1:
The system replaces the traditional mechanical key-based locking system with an electronic authentication system. Instead of using a physical key that can be lost or stolen, the system uses electronic authentication information (password, fingerprint, etc.) combined with encoding data generated by button input. This substitution eliminates the problems associated with mechanical keys while maintaining security through dual authentication.

AI summary
A dual authentication system of an electronic locking device using an electronic key according to an exemplary embodiment of the present invention includes a receiving unit that receives UID data pre-stored in the electronic key and encoding data generated by an input of a button provided in the electronic key, when a terminal portion provided in a key head of the electronic key is in electrical contact with a data communication unit of the electronic locking device; an authentication unit that performs dual authentication based on the UID data and the encoding data; and a command unit that commands the unlocking of the electronic locking device when the dual authentication on the UID data and the encoding data is successfully performed.
