Pre-Boot Keyboard Locking for Secure Remote Input Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current keyboard control methods in electronic devices are inadequate in preventing improper reinstallation of the operating system and data theft, especially in sensitive environments like police or military use, and cannot effectively manage unintended shortcut key activations.
Innovation Solution
A keyboard remote control system and method that locks the keyboard connection unit before the operating system executes, uses an embedded controller to manage keyboard access, and employs user-defined configurations and real-time monitoring to prevent unauthorized inputs, including restricted keywords and URLs, with remote control capabilities to lock the keyboard if lost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If keyboard control is performed by capturing keyboard input with a program to intercept inappropriate input after the operating system is executed, then software operation can be controlled, but it cannot prevent improper reinstallation of the operating system and data theft
Solution Approach 1:
The patent applies preliminary action by locking the keyboard connection unit before the operating system is executed. The embedded controller prevents keyboard input from being recognized prior to OS execution, thereby blocking improper reinstallation and data theft attempts before they can occur. This proactive approach addresses the security limitation of post-execution keyboard control methods.
2Reliability
If only specific keys are allowed to be used, then unauthorized inputs can be prevented, but the software operation may be disrupted due to unintended shortcut key activations
Solution Approach 1:
The patent implements dynamics by enabling real-time configuration changes of keyboard accessibility. The keyboard monitoring software can dynamically adjust which keys are enabled or disabled based on current operational context, usage scenarios, and user-defined rules. This allows the system to adapt keyboard control strategies to prevent unauthorized inputs while maintaining legitimate shortcut key functionality through context-aware activation.
3Reliability
If the keyboard connection unit is locked before the operating system is executed, then unauthorized reinstallation and data theft are prevented, but the keyboard cannot be used until unlocked
Solution Approach 1:
The patent applies feedback by implementing a keyboard monitoring software that receives real-time feedback from the embedded controller about keyboard lock status. The software monitors keyboard connection unit states and can trigger unlock actions based on detected conditions such as authorized users, valid authentication tokens, or specific usage scenarios. This feedback mechanism ensures secure locking while enabling convenient keyboard access when authorization conditions are met.

AI summary
A keyboard remote control method includes responding to an activation of an electronic device, lock a keyboard connection unit of the electronic device through an embedded controller of the electronic device before an operation system of the electronic device is executed. The keyboard remote control method further includes executing a keyboard monitoring software through the electronic device to control the embedded controller to unlock or lock the keyboard connection unit.
