Solution Overview

Problem

Conventional computing systems, particularly PCs, are vulnerable to unauthorized access due to their open architecture, which allows hackers to intercept and copy protected media by mimicking graphics devices, compromising security during content transmission.

Innovation Solution

Implementing a hardware functionality scan system that verifies the authenticity of graphics devices by testing their unique rendering capabilities and complexity, preventing unauthorized access by distinguishing real devices from emulations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional open computing systems are used, then ease of operation and adaptability are improved, but security and reliability deteriorate due to multiple access points for unauthorized access

Engineering Contradiction:

Improveease of operationVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a hardware functionality scan system as an intermediary between the open computing system and the protected content. This intermediary verifies the authenticity of hardware components through functionality scanning, creating a trust layer that enables secure content transmission while maintaining system openness and ease of operation

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If hardware components are easily removable and replaceable, then adaptability is improved, but security deteriorates as hackers can intercept and copy protected media by mimicking graphics devices

Engineering Contradiction:

ImproveadaptabilityVSAvoidunauthorized access

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent performs hardware functionality scans before transmitting protected content to verify the authenticity of graphics devices and other hardware components. This preliminary verification action ensures that only authentic, non-emulated devices can receive protected content, preventing hackers from using easily replaceable components to intercept or copy media

Inventive Principle:

Principle #10Preliminary action

3Reliability

If a chain of trust is implemented to establish security, then reliability is improved, but device complexity increases due to multiple verification components

Engineering Contradiction:

ImprovesecurityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a self-service verification mechanism where the hardware functionality scan system automatically verifies the authenticity of hardware components without requiring external intervention. The system uses built-in functionality scanning capabilities to authenticate devices, maintaining a chain of trust while minimizing additional complexity through automated self-verification processes

Inventive Principle:

Principle #25Self-service
