Solution Overview

Problem

Large language models (LLMs) generate content that may include hallucinations, inaccurate information, offensive material, or violate intellectual property, making it difficult to ensure compliance with policy standards and licensing requirements.

Innovation Solution

A trained LLM is used to oversee transactions with third-party LLMs, detecting and blocking anomalous interactions, and reporting misuse by analyzing transaction data on a distributed ledger, employing modules for anomaly detection and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a trained LLM is used to oversee and detect misuse in transactions, then the reliability of content safety is improved, but the device complexity increases due to additional monitoring and evaluation modules

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

Solution Approach 1:

A trained LLM serves as an intermediary security module between the distributed ledger and the third-party LLM service. This intermediary detects anomalies and blocks misuse without requiring complex centralized control systems, resolving the contradiction by using a specialized AI layer that simplifies the overall architecture while improving safety reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If anomaly detection modules are added to monitor LLM transactions, then the reliability of misuse detection is improved, but the processing time increases

Engineering Contradiction:
Improvemisuse detectionVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-training the LLM on security protocols and policies before actual transactions occur. This pre-training enables the model to quickly identify and block anomalies during transaction processing without requiring real-time complex analysis, thus improving detection reliability while minimizing processing time delays

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a distributed ledger is used to track transactions, then the reliability of transaction tracking is improved, but the device complexity increases due to ledger integration requirements

Engineering Contradiction:
Improvetransaction trackingVSAvoidledger integration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The distributed ledger is integrated into an existing multi-functional platform that handles both transaction recording and AI model deployment. This universal approach allows the same infrastructure to serve multiple purposes including transaction tracking, model execution, and security monitoring, thereby improving reliability without proportionally increasing complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Disclosed are various embodiments for a distributed ledger enabled large language model security protocol. A large language model (LLM) can filter data generated by a distributed agent for a trace of a transaction with a third-party LLM. A trained LLM can analyze any found trace of a transaction and identify at least an anomaly related to the found trace. The trained LLM can block the transaction based on the anomaly.
