Solution Overview

Problem

Conventional multi-tiered distributed systems face challenges in maintaining visibility and compliance verification of semiautonomous or autonomous agents due to limited insight into upstream operations, with existing methods risking disclosure of sensitive information and lacking dynamic, context-aware verification across organizational boundaries.

Innovation Solution

An agent management platform utilizing a distributed ledger and zero-knowledge proofs enables cryptographically verifiable compliance across multi-agent, multi-tier systems, allowing agents to attest to compliance without disclosing protected data, and dynamically adapting to changes in agent composition and operational contexts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If conventional multi-tiered distributed systems are used to manage autonomous agents, then system complexity and autonomy are improved, but visibility and compliance verification deteriorate due to limited insight into upstream operations

Engineering Contradiction:
Improveagent autonomyVSAvoidvisibility into upstream operations
Core Design Contradiction:
Extent of automationVSLoss of information

Solution Approach 1:

A blockchain-based intermediary layer is introduced between autonomous agents and the central management system. This intermediary provides a decentralized ledger that records all agent actions and compliance status, enabling visibility into upstream operations without requiring direct access to sensitive agent data or reducing agent autonomy. The blockchain acts as a trusted mediator that verifies and broadcasts compliance information across the multi-tiered system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If compliance verification methods disclose sensitive information to enable auditing, then compliance visibility is improved, but data privacy deteriorates

Engineering Contradiction:
Improvecompliance visibilityVSAvoiddisclosure of sensitive information
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the essential compliance verification information from sensitive agent data and stores it on the blockchain. Instead of disclosing complete operational data, the system extracts and records specific compliance metrics, audit trails, and verification status. This extraction approach enables compliance auditing while preserving the privacy of sensitive operational details that are not needed for verification purposes.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Different parts of the system have different levels of information access. The blockchain provides global visibility of compliance status, while sensitive local operational data remains protected within individual agents or organizations. This local quality approach ensures that each entity maintains appropriate control over its sensitive data while contributing necessary compliance information to the shared ledger.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If batch-mode workflows are used for compliance checking, then data privacy is maintained, but productivity deteriorates due to lag in detection and propagation

Engineering Contradiction:
Improveoperational data privacyVSAvoidcompliance detection speed
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The blockchain-based system enables continuous, real-time compliance verification instead of periodic batch processing. As agents execute actions and update the blockchain ledger, compliance status is continuously monitored and verified by network participants. This continuous action eliminates the lag inherent in batch-mode workflows while maintaining data privacy through cryptographic verification methods that do not require exposure of sensitive operational data.

Inventive Principle:
Principle #20Continuity of useful action

4Reliability

If centralized compliance monitoring is implemented, then compliance verification is improved, but device complexity and single points of failure increase

Engineering Contradiction:
Improvecompliance verificationVSAvoidcentralized system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the compliance verification function across multiple distributed nodes in the blockchain network rather than concentrating it in a single centralized authority. Each node independently verifies compliance based on the immutable ledger records, providing redundant verification capabilities. This segmentation reduces single points of failure and distributes system complexity across the network, improving reliability without requiring a complex centralized monitoring infrastructure.

Inventive Principle:
Principle #1Segmentation

AI summary

Systems and methods disclosed herein perform privacy-preserving evaluations of artificial intelligence (AI) agents. A first AI agent associated with a first entity obtains a machine-readable data structure defining one or more operative boundaries for a second AI agent associated with a second entity. The system generates a unique fixed reference value representing the machine-readable data structure by applying a first transformation operation set, and transmits the unique fixed reference value to a multi-agent storage to store the value. The system receives, via the multi-agent storage, a verification artifact from the second AI agent that indicates an observed value based on internal operational data of the second AI agent corresponding to the operative boundaries. The first AI agent determines a verification status of the verification artifact by comparing the unique fixed reference value with the observed value, and autonomously generates a verification record including a representation of the verification status.
