Hypervisor Scratch OS for Email Virus Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antivirus tools are ineffective against unknown email viruses and cannot prevent irreparable damage to computers if they are not up-to-date or encounter new virus threats.
Innovation Solution
Utilizing a Type 1 hypervisor to create a secondary operating system, known as the 'Scratch OS', which isolates and validates email communications, running antivirus tools to detect and contain potential viruses, thereby preventing damage to the primary User Operating System.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional antivirus tools are used to protect against email viruses, then protection against known viruses is provided, but protection against unknown or new viruses is ineffective
Solution Approach 1:
The system segments the operating environment by creating a virtualized Scratch OS that is isolated from the User OS. Email activities are contained within this separate virtual environment, allowing unknown viruses to be tested without affecting the main system. This segmentation enables both protection against known viruses and safe testing against unknown viruses simultaneously.
Solution Approach 2:
The system performs preliminary action by creating a clean Scratch OS environment before opening email attachments. This pre-prepared isolated environment allows the system to safely execute and test unknown viruses in advance, detecting their behavior before they can reach the User OS. The Scratch OS is discarded after testing, ensuring no contamination persists.
2Ease of operation
If email attachments are opened directly in the User Operating System, then email functionality is maintained, but the system becomes vulnerable to virus damage
Solution Approach 1:
The Scratch OS acts as an intermediary between the email attachments and the User OS. All email opening and attachment execution activities are routed through this virtualized environment, which mediates the interaction while containing any harmful effects. The hypervisor manages this intermediary layer, ensuring that even if viruses are activated, they cannot escape to damage the User OS.
3Reliability
If a hypervisor is introduced to create isolated operating systems for virus testing, then protection against unknown viruses is improved, but system complexity increases
Solution Approach 1:
The Scratch OS is designed to be self-contained and self-managed through the hypervisor. It automatically receives email attachments, executes them in isolation, and is then discarded after testing. This self-service approach minimizes the need for complex manual management of the virtualized environment, reducing operational complexity despite the advanced architecture.

AI summary
Hypervisors are a new technology in the industry that enable multiple Operating Systems to co-exist on a single client. The use of a hypervisor provides a novel approach to email virus protection. The hypervisor is able to fire up an Operating System on demand, for a specific purpose, or have it running from the powering of the computer. A second Operating System can be provided as a donor Operating System that acts as a scratch area or scratch pad. Emails sent to the recipient are opened under the donor Operating System, or the “Scratch OS”. Once the email activities are complete, the “Scratch OS” can be discarded. Thus, any damage that may be caused by an email virus would be nil, and further the User Operating System would be undamaged. This method would be effective in precluding any damage that a virus may have done.
