Contactless Communication Lock via Email Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote function lock technologies for contactless communication devices in mobile communication terminals are ineffective when the terminal has an incoming call reject function set, allowing unauthorized use and potential loss of sensitive information.
Innovation Solution
A method that allows remote locking of contactless communication devices via a wired communication path by registering lock request email content, deciding on the lock state, and executing the lock if necessary, even if the terminal has incoming call rejection enabled, with optional notification and confirmation mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional remote function lock technology using call origination operation is used, then the function lock can be executed when the mobile communication terminal is lost, but the lock cannot be performed when incoming call reject function is set, allowing unauthorized use
Solution Approach 1:
The patent introduces an email-based intermediary mechanism to bridge the gap between the lock request and the terminal. Instead of relying on call origination operations that are blocked by incoming call reject settings, the system uses email notifications as a mediator to deliver lock commands to the terminal, bypassing the call rejection barrier while ensuring the lock function can still be executed reliably
Solution Approach 2:
The patent replaces the mechanical/telephony-based call origination operation with an email-based communication system. By substituting the call mechanism with email notification and wired communication path, the system eliminates the conflict with incoming call reject functions while maintaining the remote lock capability
2Ease of operation
If call origination operation is used for remote lock, then the lock can be triggered remotely, but the operation is blocked when incoming call reject is enabled, creating security vulnerability
Solution Approach 1:
The email notification serves as an intermediary that carries the lock command from the external system to the terminal without being affected by call rejection settings. This intermediary mechanism maintains ease of operation while ensuring the lock command can reach the terminal reliably even when call origination is blocked
Solution Approach 2:
The patent changes the communication parameter from voice call origination to email notification delivery. By altering the communication medium from telephony to email, the system maintains operational ease while eliminating the blocking effect caused by incoming call reject functions, thereby ensuring lock effectiveness

AI summary
A user of a mobile communication terminal registers a title or test body that a lock request electronic mail should have for locking function of a contactless type communication device is a lock control information area 23R of the mobile communication terminal. After that, if a lock request electronic mail having the registered title is received, and the lock request electronic mail is detected by the lock request detection section 51, then when the contactless type communication device is in a usable state, in the mobile communication terminal the function lock section 52 within the control section locks the function of the contactless type communication device via the wired communication path.
