Contactless IC Card Function Lock Notification via Mobile Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote function lock methods for contactless communication devices in mobile communication terminals do not reliably notify users that the lock has been successfully implemented, leading to uncertainty about the lock status.
Innovation Solution
A function lock information notification method that uses a mobile communication network to request a lock for a contactless communication device, lock the device via a wired communication path, and notify a pre-registered party that the lock has been applied, allowing users to confirm the lock status through a mobile communication terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote function lock is implemented via mobile communication network, then security of contactless communication device is improved, but user confirmation of lock status becomes unreliable
Solution Approach 1:
The patent implements a feedback mechanism where the mobile communication terminal sends lock status notification back to the user's terminal through the mobile communication network. This allows the user to confirm whether the remote lock command was successfully executed, resolving the information loss problem while maintaining the security improvement.
Solution Approach 2:
The system performs preliminary registration of the user's terminal information before the lock operation. This pre-registration enables the subsequent notification to be sent to the correct terminal, ensuring that the feedback loop can be established quickly and reliably when the lock command is executed.
2Ease of operation
If lock command is sent remotely through mobile communication network, then ease of operation is improved, but reliability of lock execution confirmation deteriorates
Solution Approach 1:
The patent establishes a feedback loop where the mobile communication terminal notifies the user's terminal of the lock execution status. This maintains the ease of remote operation while resolving the reliability issue by providing concrete confirmation that the lock was successfully applied.
3Loss of information
If function lock notification is implemented via mobile communication network, then user awareness of lock status is improved, but device complexity increases
Solution Approach 1:
The patent utilizes the existing mobile communication network for both the initial lock command transmission and the subsequent status notification. This multi-functional use of the same communication infrastructure provides lock status information to the user without adding significant device complexity, as no separate notification channel is required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method ensures users can confirm that the contactless communication device is locked, enhancing convenience and security by providing clear notification of the lock status, even when the device is lost.
Implementation Method 1
a contactless communication device, which performs contactless type communication utilizing radio communication between communicating parties, such as a reader writer... derives operating power using electromagnetic induction generated by radio waves from a communicating party received by an antenna (coil) mounted within the device

AI summary
If a lock request for function of an IC card function section is executed from a locking terminal via a mobile communication network, a lock request detection section 51 detects the lock request. If the lock request is detected in this manner, the function lock section 52 locks the function of the IC card function section by sending a function lock instruction via a wired communication path to the IC card function section. The function lock notification section 53 then notifies the fact that the function has been locked to a locking notification mail communication unit pre-registered in the terminal registration table 23T via the mobile communication network. In this way, since function lock information of a contactless type communication device fitted in a mobile communication terminal is appropriately notified via a mobile communication network, convenience for the user is improved.
