Remote Computer Lockdown via Telephone Network Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often find it inconvenient or impossible to remotely lock down their computers to a secure state, especially when they cannot physically access them, which poses a risk to data and software security, especially in cases of theft.
Innovation Solution
A method and apparatus that utilize a network client system with a unique number, connected via a telephone network, to receive and process a remotely transmitted data packet, determining if it includes the unique number and locking down the system if it does, employing technologies like the Magic Packet for remote command and control, including a network interface card, processor, and executable software to manage the computer's state transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user physically accesses the computer to lock it down, then the lock-down procedure can be performed reliably, but it becomes impossible or inconvenient when the user cannot return to the computer
Solution Approach 1:
The patent introduces a telephone network as an intermediary communication channel between the user's mobile phone and the computer system. The system receives lock-down commands via telephone calls, allowing remote initiation of the lock-down procedure without requiring direct physical access to the computer. This mediator enables reliable lock-down execution even when the user cannot return to the computer location.
2Ease of operation
If the computer is left unlocked for convenience, then access is easier, but security risk increases when the user cannot secure it
Solution Approach 1:
The system enables users to initiate the lock-down action in advance from a remote location via telephone network before leaving or when security becomes a concern. The unique identifier matching mechanism ensures that only authorized lock-down commands are executed, allowing the computer to remain accessible during normal use while providing a quick security response when needed.
3Object-affected harmful factors
If remote lock-down capability is added, then security is improved when physically inaccessible, but system complexity increases
Solution Approach 1:
The system utilizes the existing telephone network infrastructure for remote communication, leveraging a widely available and familiar communication channel. The network client system's existing network interface and processor are multi-used to handle both local operations and remote lock-down commands, reducing the need for dedicated specialized hardware and minimizing overall system complexity.
4Speed
If the system continuously monitors for lock-down commands, then response time is reduced, but energy consumption increases
Solution Approach 1:
The system employs event-driven network monitoring where the network interface checks for incoming calls or data packets at periodic intervals rather than maintaining continuous active monitoring. When a call or data packet is detected, the system quickly processes the lock-down command if the unique identifier matches. This periodic approach significantly reduces energy consumption compared to continuous monitoring while maintaining fast response capability when commands are actually sent.
