Solution Overview

Problem

The challenge of trusting whether a real person or a deepfaked version is participating in audio and/or video conferences poses a security risk, as existing systems lack effective methods to authenticate participants and provide real-time feedback on trust levels.

Innovation Solution

A communication system and method that determine and display trust levels based on media data from audio and video devices, using cryptographic keys, signatures, and biometric data to verify the authenticity of participants, and provide real-time feedback to users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional communication systems are used without trust verification, then the system complexity remains low and ease of operation is maintained, but security and reliability deteriorate due to susceptibility to deepfake attacks and impersonation

Engineering Contradiction:
Improvetrust verificationVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary verification of media streams by checking cryptographic signatures and biometric data before establishing trust. This advance verification prevents impersonation attacks without requiring complex real-time analysis during communication, as the trust assessment is prepared in advance through pre-established cryptographic credentials.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary trust assessment mechanism that mediates between communication parties. This intermediary layer verifies media streams through cryptographic validation and biometric matching, providing security without requiring direct complex interactions between participants, thus maintaining ease of operation while improving reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If real-time trust level monitoring is implemented, then security and awareness are improved, but information processing requirements and system complexity increase

Engineering Contradiction:
Improvetrust awarenessVSAvoidprocessing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system implements feedback by continuously monitoring media streams and providing real-time trust level updates to participants. This feedback mechanism maintains trust awareness without requiring complex centralized control, as each participant independently assesses trust levels based on verified cryptographic and biometric data from incoming streams.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables self-service trust verification where each communication participant independently validates media streams using pre-distributed cryptographic keys and biometric templates. This distributed self-verification approach reduces central processing requirements while maintaining real-time trust awareness across all participants.

Inventive Principle:
Principle #25Self-service
