Solution Overview

Problem

Existing technologies struggle to differentiate between authentic and AI-generated content, particularly deepfakes, leading to security risks and misinformation, as watermarking methods can be easily removed and attackers may avoid detection.

Innovation Solution

Utilizing a secure execution environment within user devices to verify and sign sensor data, ensuring authenticity by generating a signature that is authenticated by a computing resource service provider before distribution.

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If watermarking methods are used to identify AI-generated content, then detection capability is improved, but the method is easily removed or bypassed by attackers

Engineering Contradiction:

Improvedetection capabilityVSAvoidsecurity reliability

Core Design Contradiction:

Difficulty of detecting and measuringVSReliability

Solution Approach 1:

The patent applies preliminary action by embedding authentication data and signatures into the content generation process itself, rather than attempting to detect AI-generated content after creation. The system preemptively marks content with cryptographic signatures during generation, making the authentication inherent to the content rather than a post-hoc detection layer that can be bypassed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary authentication layer consisting of cryptographic signatures and authentication data that mediates between the content generator and the verification system. This intermediary mechanism provides reliable verification by using cryptographic proofs that are computationally infeasible to forge, rather than relying on detectable watermarks that attackers can remove or evade.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If secure execution environments are used to verify and sign sensor data, then authenticity is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex secure verification and signing operations into a dedicated secure execution environment (such as a trusted execution environment or hardware security module) that is isolated from the main application logic. This separation allows the complex cryptographic operations to be performed in a secure, standardized manner without burdening the main system architecture, thereby achieving high authenticity while managing device complexity through modular design.

AI summary

Various embodiments of the technology described herein relate to distribution-verified and authenticated content, including obtaining content and authentication data from a user device, authenticating the content based on the authentication data, and distributing the content, including an indication that the content has been verified and/or authenticated. For example, an entity depicted in the content is verified, and data depicting the entity (e.g., video and/or audio) is authenticated and distributed to various user devices.
