Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems lack efficient methods for ensuring regulatory and policy compliance in the transfer of tokenized assets, particularly in decentralized financial transactions across multiple distributed ledgers.

Innovation Solution

A compliance enhanced architecture is implemented, comprising a Policy Enforcement Point (PEP), rules engine, attribute source module, and recipes, which utilize a Subject Verb Object (SVO) structure to determine transaction rights based on participant, token, and transaction attributes, enabling compliance-aware token creation and enforcement across dissimilar networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If decentralized financial transactions are enabled across distributed ledgers, then financial freedom and accessibility are improved, but regulatory compliance and transaction control become more difficult to enforce

Engineering Contradiction:

Improvefinancial accessibilityVSAvoidregulatory compliance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

A Policy Enforcement Point (PEP) acts as an intermediary component that mediates between decentralized transaction requests and regulatory requirements. The PEP intercepts transaction requests, evaluates them against policy rules stored in a rules engine, and enforces compliance decisions without preventing decentralized operation. This intermediary layer enables both financial accessibility and regulatory compliance by translating regulatory requirements into executable policy rules that the decentralized system can follow.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If comprehensive policy enforcement is implemented for token transactions, then regulatory compliance is improved, but system complexity increases

Engineering Contradiction:

Improvecompliance enforcementVSAvoidsystem architecture

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The Policy Enforcement Point serves multiple functions within a single component: it intercepts transactions, retrieves policy rules, evaluates compliance, enforces decisions, and logs outcomes. The rules engine also performs multiple roles by storing rules, evaluating them against transaction attributes, and providing policy decisions. This multi-functionality reduces overall system complexity compared to having separate specialized components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables self-service compliance enforcement where the PEP autonomously evaluates transactions against stored policy rules and enforces decisions without requiring external regulatory intervention for each transaction. The rules engine automatically retrieves relevant rules, evaluates transaction attributes against those rules, and provides compliance decisions, reducing the need for manual policy management and external system complexity.

Inventive Principle:

Principle #25Self-service

3Measurement precision

If transaction evaluation against multiple rules is performed, then compliance accuracy is improved, but processing time increases

Engineering Contradiction:

Improvecompliance accuracyVSAvoidtransaction processing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The rules engine performs partial evaluation by first checking transaction attributes against rules and only fully evaluating rules that are relevant to the specific transaction type and attributes. Not all stored policy rules need to be evaluated against every transaction - the system selectively applies rules based on transaction characteristics, reducing processing time while maintaining compliance accuracy for applicable rules.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

Policy rules are pre-loaded and stored in the rules engine before transaction evaluation begins. The rules engine maintains a ready cache of policy rules that can be quickly retrieved and evaluated against transaction attributes. This preliminary preparation of rule sets eliminates the need to fetch and parse rules during transaction processing, significantly reducing evaluation time while maintaining comprehensive compliance checking.

Inventive Principle:

Principle #10Preliminary action

AI summary

An apparatus, computer-readable medium, and computer-implemented method to facilitate scalable compliance and issuer governance of decentralized financial transactions especially for the trade and transfer of tokenized securities. The resulting Compliance Aware Tokens contain the rulesets to restrict transactions and facilitate regulatory reporting and oversight. The embodied process, includes of a novel combination of compliance workflows, attribute verification tools, smart contracts and other ledger controls, provides a decentralized Attribute Based Access Control (ABAC) capability. ABAC patterns are extended to govern global financial transactions without the need for an active intermediary.
