Solution Overview

Problem

Home networks, particularly those equipped with encryption software, are vulnerable to attacks, and users lack the expertise to install and maintain security tools, leading to distrust and hesitation in adding unsecured devices.

Innovation Solution

Implementing malware detection logic in secured devices and cloud-based systems to detect and prevent malicious software, ensuring secure communication channels and managing device integration through validation tests and encryption processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If encryption software is implemented in home networks, then security against external threats is improved, but users still lack the expertise to maintain security tools and install secure devices

Engineering Contradiction:
Improvenetwork securityVSAvoiduser ability to maintain security tools
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces an intermediary device (gateway or router) that automatically performs security functions including malware detection, validation testing, and secure communication management. This intermediary shields users from complex security maintenance tasks while maintaining high security standards, resolving the contradiction between improved security and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If security tools are installed to protect home networks, then protection against malware and attacks is improved, but device complexity and difficulty of configuration increase

Engineering Contradiction:
Improveprotection against malwareVSAvoidsecurity tool configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service mechanisms where the security system automatically performs malware detection, validation testing of new devices, and threat response actions without requiring user configuration or maintenance. The system autonomously manages its own security operations, reducing complexity while maintaining strong protection capabilities.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If unsecured devices are added to home networks, then device functionality and versatility are improved, but network vulnerability to hacking and piracy increases

Engineering Contradiction:
Improvedevice integration capabilityVSAvoidnetwork vulnerability
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements preliminary action by performing validation testing and malware detection on devices before they are fully integrated into the home network. The system proactively identifies security threats and prevents vulnerable devices from compromising the network, allowing versatile device integration while maintaining security through advance verification.

Inventive Principle:
Principle #10Preliminary action

AI summary

Malware detection logic executed by a secured device residing in a home network may receive a message from an unsecured device of a first unsecured network and intended for a destination device of the home network, the destination device comprising a security client. The malware detection logic may establish a secure communication channel between the malware detection logic of the secured device and the security client of the destination device. The malware detection logic may execute a validation test on the message to determine that the message includes malware. The malware detection logic may report an alarm to the security client of the destination device. The malware detection logic may transmit information related to the malware to a cloud computing server. The malware detection logic may prevent an application associated with the destination device from processing the message.
