Hardware Switch for Peripheral Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to disable integrated peripherals in computing devices securely and efficiently, particularly to prevent malware interference and ensure data privacy, as existing technologies lack a reliable method for direct hardware control over peripheral connections.
Innovation Solution
A peripheral disconnection switch system that includes a hardware switch connected to at least one peripheral, allowing for direct electrical control over the connection between the peripheral and the processor, enabling the peripheral to be disabled by physically disconnecting the circuit line or generating an interrupt, while ensuring proper signal termination and maintaining peripheral operability for quick reconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If integrated peripherals remain constantly connected to the processor via bus for ease of operation, then peripheral functionality is always available, but security vulnerability increases due to potential malware interference
Solution Approach 1:
The patent introduces a hardware switch as an intermediary component positioned between the peripheral and the processor bus. This switch acts as a physical mediator that can disconnect the peripheral from the system bus, preventing malware from accessing or interfering with the peripheral while maintaining the ability to reconnect when needed. The switch provides a security layer without permanently sacrificing peripheral availability.
2Object-affected harmful factors
If a hardware switch is introduced to disconnect peripherals for security, then security against malware is improved, but device complexity increases
Solution Approach 1:
The patent segments the connection between the peripheral and the processor by introducing a discrete hardware switch component. This segmentation allows the system to be divided into controllable sections, where the switch can independently manage the connection state without affecting other system components. The modular nature of the switch keeps the added complexity localized and manageable.
3Object-affected harmful factors
If peripherals are physically disconnected to prevent malware access, then security is enhanced, but reconnection time and complexity increase
Solution Approach 1:
The hardware switch is designed to be user-operable, allowing individuals to independently connect or disconnect peripherals without requiring technical expertise, driver reinstallation, or complex system configuration. The switch provides self-service functionality where the user can quickly restore peripheral access by simply operating the switch, eliminating the time-consuming reconnection processes associated with traditional disconnection methods.
