Electronic Key System Server-Controlled ID Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic key systems do not effectively prevent unauthorized use of ID information stored in multiple devices, especially when one device is lost and still powered on, as they require turning off the device to secure the information.
Innovation Solution
An electronic key system that uses a server to control the locking and unlocking of ID information output across multiple devices, ensuring only one device is unlocked at a time, with a switching mechanism that allows secure swapping of lock and unlock states even when communication with the server is unavailable, using a near field communication device and clone table for consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ID information is stored in multiple electronic devices for convenient access, then ease of operation is improved, but security is worsened because any powered-on device can be used by a third party if lost
Solution Approach 1:
The system dynamically changes the availability parameter of ID information across multiple devices. The server controls whether ID information can be output from each device by changing its availability state between locked and unlocked, ensuring that even if devices are lost, the ID information cannot be used when in locked state
Solution Approach 2:
The server continuously monitors and controls the availability of ID information across all devices. When a device is reported lost or unauthorized use is detected, the server provides feedback by locking the ID information output on that device, creating a closed-loop security system that responds to security events
2Reliability
If the power of an electronic device is turned off to prevent unauthorized use of ID information, then security is improved, but ease of operation is worsened because the device cannot be used when needed
Solution Approach 1:
Instead of changing the power state of the device, the system changes the availability parameter of ID information output. The ID information can be locked or unlocked independently of device power state, allowing devices to remain powered on for normal use while preventing unauthorized ID information usage through server-controlled locking
3Ease of operation
If ID information output is unlocked on multiple devices simultaneously for user convenience, then ease of operation is improved, but security is worsened because the risk of ID information theft increases
Solution Approach 1:
The server dynamically adjusts the availability parameter of ID information across devices based on security requirements. It can lock ID information on specific devices while keeping it unlocked on others, or control the number of simultaneously unlocked devices, thereby managing the risk exposure while maintaining operational convenience

AI summary
In a network to which a plurality of electronic devices and a server are connected, an electronic key system controls locking and unlocking of ID information output of each electronic device. Each electronic device includes a switching device that locks or unlocks output of ID information of each electronic device. The server includes an availability changing unit and a management unit. The availability changing unit unlocks only one of the plurality of electronic devices and locks the other electronic devices. The management unit updates a state at which the locking of ID information output and the unlocking of ID information output are swapped between a pair of the electronic devices.
