Client Computer Remote Control Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control systems connected through networks are vulnerable to unauthorized access due to hacked or disclosed passwords, risking the leakage of precious information and data.
Innovation Solution
A client computer system connected to a host computer via a network, which receives locking and unlocking signals to control its operations, including power supply and user input, to prevent unauthorized access by authenticating passwords and maintaining a locking state until proper authorization is received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If password-based authentication is used for remote control access, then ease of operation is improved, but security reliability deteriorates when passwords are hacked or disclosed
Solution Approach 1:
A locking mechanism acts as an intermediary between the authentication system and the remote control functionality. When a locked state is detected, this intermediary blocks all remote control operations regardless of authentication status, preventing direct access to the system while maintaining the authentication infrastructure.
Solution Approach 2:
The system performs preliminary locking actions before allowing any remote control operations. The controller continuously monitors for locked states and prevents operations from being executed if locking is detected, ensuring security is established before any potential breach can occur.
2Productivity
If the client computer allows full operation, then productivity is improved, but loss of information increases when passwords are compromised
Solution Approach 1:
The system applies preliminary anti-action by detecting locked states and preemptively blocking all operations that could lead to information leakage. When locking is detected, the controller prevents any remote control commands from executing, thereby preventing data exposure before it can occur.
Solution Approach 2:
The remote control functionality is extracted and separated from the core system operations. When a locked state is detected, the remote control operations are removed from the execution path, allowing the system to maintain productivity through normal operations while preventing unauthorized remote access.
3Reliability
If the system implements locking mechanism, then security reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is merged with the existing controller and communication infrastructure. The controller integrates the locking detection and operation blocking functions into its existing architecture, and the locking information is transmitted through the existing communication part, avoiding the need for separate complex security hardware.
Solution Approach 2:
The communication part serves multiple functions: it handles normal remote control communication and simultaneously transmits locking state information. The controller also performs multiple functions by integrating both operation execution and locking state monitoring, reducing the need for dedicated security components.

AI summary
A client computer that is connectable to a host computer by a network, includes a communication part to communicate with the host computer; a user input part; a system part to perform a function depending on an application; and a controller to control the system part to be put into a locking state to stop performing operations input by a user from the user input part if a locking signal is received from the host computer through the communication part, and to control the communication part to unlock the locking state if an unlocking signal is received from the host computer through the communication part.
