Solution Overview

Problem

Generative AI models lack authentication and attribution mechanisms, making it difficult to enforce intellectual property rights, prevent misuse, and distinguish between synthetic and real data, particularly with the rise of deepfake technology.

Innovation Solution

Implementing an authentication key system within generative AI models to authenticate and embed metadata within outputs, ensuring higher quality when the key is valid, and allowing extraction of authentication and attribution information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If generative AI models generate content without authentication mechanisms, then content generation speed and ease of use are improved, but intellectual property rights cannot be enforced and content authenticity cannot be verified

Engineering Contradiction:
Improveease of useVSAvoidcontent authenticity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary authentication by embedding an authentication key within the generated content before the content is used or distributed. This advance preparation ensures that authenticity verification can be performed later without impacting the ease of content generation or usage.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The authentication key acts as an intermediary element embedded within the generated content. This key serves as a mediator that enables verification of content authenticity and enforcement of intellectual property rights without interfering with the normal content generation process or user interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If authentication keys are embedded within generated outputs, then content authenticity and intellectual property protection are improved, but device complexity and processing requirements increase

Engineering Contradiction:
Improvecontent authenticityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The authentication key is merged directly into the generated content output rather than being stored separately. This combining of the authentication mechanism with the content itself simplifies the system architecture by eliminating the need for separate authentication storage and retrieval systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The generated content carries its own authentication key embedded within it, enabling self-verification of authenticity. The content essentially authenticates itself without requiring external authentication systems, reducing overall system complexity.

Inventive Principle:
Principle #25Self-service

3Reliability

If quality of output varies based on authentication key validity, then intellectual property rights enforcement is improved, but loss of information occurs when keys are not valid

Engineering Contradiction:
Improveintellectual property protectionVSAvoidcontent quality
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system changes the quality parameter of the generated output based on the validity of the authentication key. When the key is valid, full-quality content is generated; when invalid, reduced-quality content is produced. This parameter adjustment enforces intellectual property rights while maintaining a functional output.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The potential harm of reduced content quality when authentication fails is converted into a benefit for intellectual property protection. The quality reduction serves as a deterrent against unauthorized use while still providing some functional output, transforming what could be seen as a loss into a protective mechanism.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

In some implementations, a system may receive an authentication key associated with authenticating use of a generative AI model. The system may receive an input prompt. The system may generate, using the generative AI model, an output based on the input prompt. The authentication key is embedded within the output. A quality of the output is higher when the authentication key is valid than when the authentication key is not valid.
