Solution Overview

Problem

Large language models (LLMs) pose risks due to potential misuse, generation of deceptive and inaccurate content, perpetuation of biases, and privacy concerns, necessitating effective risk mitigation strategies.

Innovation Solution

Implementing a networked environment with a computing environment, LLM security service, and risk mitigation code to identify and modify LLM applications, using pre-sink method techniques and kernel-level interception to manage interactions, ensuring secure and accurate outputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If LLMs generate highly realistic and coherent text, then text quality and coherence are improved, but accuracy and reliability deteriorate

Engineering Contradiction:
Improvetext coherenceVSAvoidoutput accuracy
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent introduces an intermediary verification system that sits between the LLM generation process and the final output. This intermediary layer checks generated content against knowledge bases, fact-checks information, and validates coherence without compromising the LLM's ability to generate realistic text. The intermediary acts as a mediator that preserves text quality while ensuring accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If LLMs are used to expand AI capabilities, then functionality and utility are improved, but security and data protection worsen

Engineering Contradiction:
ImproveAI functionalityVSAvoiddata security
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the AI system into multiple independent components: the LLM generation module, the security verification module, the data protection layer, and the output validation module. Each segment handles specific functions independently, allowing the system to expand functionality through the LLM while security concerns are addressed by dedicated separate modules that do not compromise the core generative capabilities.

Inventive Principle:
Principle #1Segmentation

3Productivity

If LLMs generate content quickly, then productivity is improved, but risk of misuse and erroneous output worsens

Engineering Contradiction:
Improvecontent generation speedVSAvoidoutput reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements preliminary actions by pre-training the LLM on high-quality, verified data and pre-loading knowledge bases with accurate information before generation occurs. Additionally, verification rules and safety constraints are pre-configured into the system. This preliminary preparation enables the LLM to generate content quickly while reducing the need for extensive post-generation checking, thus maintaining both speed and reliability.

Inventive Principle:
Principle #10Preliminary action

AI summary

Disclosed are various approaches for large language model (LLM) application risk mitigation. A large language model (LLM) application along with a LLM risk mitigation program can be deployed. A system call for the LLM application is intercepted, in which the system interacts with a network LLM service using the LLM risk mitigation program. An LLM risk mitigation action is executed and modifies the system call using the LLM risk mitigation program based at least in part on a packet from the system call.
