Solution Overview

Problem

Conventional security systems fail to address the unique security concerns of generative AI platforms, including the ingestion and generation of fictitious information and autonomous decision-making that can lead to harmful outcomes.

Innovation Solution

Implementing a security interceptor that requires a valid 'Safe for Artificial Intelligence' (SFAI) token for all communications entering and exiting the generative AI platform, ensuring the integrity and trustworthiness of the data and sources interacting with it.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional security systems are used to protect generative AI platforms, then basic authentication and authorization are provided, but they fail to address unique security concerns including ingestion of fictitious information and autonomous decision-making that can lead to harmful outcomes

Engineering Contradiction:

Improvesecurity protection effectivenessVSAvoidfictitious information ingestion and harmful autonomous decisions

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a security interceptor as an intermediary component that sits between the generative AI platform and external data sources. This interceptor validates data before it enters the platform and monitors communications to prevent harmful information from being ingested, thereby addressing the limitation of conventional security systems that lack specialized validation capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The security interceptor performs preliminary validation of data and communications before they reach the generative AI platform. By checking safety levels and authentication tokens in advance, the system prevents harmful information from entering the platform, rather than relying on post-detection or reactive security measures.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the generative AI platform allows autonomous decision-making and data ingestion, then productivity and adaptability are improved, but the platform becomes susceptible to making harmful decisions and ingesting fictitious information

Engineering Contradiction:

Improveautonomous decision-making capabilityVSAvoidharmful decisions and fictitious information

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The security interceptor implements feedback mechanisms that continuously monitor the generative AI platform's communications and data ingestion activities. When potential harmful patterns are detected, the interceptor provides feedback to block those communications, allowing the platform to maintain autonomous operation while being protected from harmful influences.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The security interceptor acts as a mediator between the autonomous generative AI platform and external data sources, enabling the platform to maintain its productive autonomous decision-making capabilities while preventing harmful information from entering the system through validated authentication and safety checks.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If a security interceptor validates all communications with SFAI tokens, then data integrity and trustworthiness are improved, but communication overhead and system complexity increase

Engineering Contradiction:

Improvedata integrity and trustworthinessVSAvoidcommunication validation system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The security interceptor is designed as a multi-functional component that handles multiple security tasks including authentication token validation, safety level checking, and communication monitoring. By consolidating these functions into a single interceptor, the system achieves comprehensive data integrity validation without proportionally increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The security interceptor performs validation actions in advance of actual data processing, establishing trust relationships and safety clearances before communications occur. This preliminary action reduces the need for complex real-time validation during data ingestion, thereby managing system complexity while maintaining high data integrity standards.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method of protecting a generative artificial intelligence (AI) platform can include receiving, at a security interceptor, a plurality of communications from the generative AI platform to one or more sources over a network, wherein each communication of the plurality of communications comprises a source-specific safe-for-AI token (SFAI token) associated with a particular source of the one or more sources appended thereto; checking, by the security interceptor, a safety level of each source-specific SFAI token received with the plurality of communications; for each source-specific SFAI token having a safety level indicating a permitted source, permitting a corresponding communication comprising that source-specific SFAI token to be transmitted to the particular source associated therewith; and for any communication of the plurality of communications comprising a corresponding source-specific SFAI token having a safety level indicating a proscribed source, blocking that communication to be transmitted to the particular source associated therewith.
