Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Fraudulent activities involving negotiable instruments, such as checks, can go undetected for weeks or months as they are deposited multiple times across different financial institutions, leading to resource wastage and financial losses for both customers and institutions.

Innovation Solution

A distributed ledger system, specifically a blockchain, is used to uniquely identify negotiable instruments through machine-readable codes, verifying their legitimacy and preventing duplicate deposits by maintaining a record of transactions, thereby alerting financial institutions to potential fraud.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a negotiable instrument is deposited at multiple financial institutions without centralized tracking, then the deposit process is simple and fast, but fraud goes undetected for weeks or months

Engineering Contradiction:

Improvefraud detection capabilityVSAvoidtime to detect fraud

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent merges the isolated verification systems of multiple financial institutions into a single distributed ledger system. Each institution's transaction data is combined into a shared blockchain, enabling centralized fraud detection capability across the entire network while maintaining the decentralized architecture that prevents any single institution from having centralized control.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The distributed ledger system acts as an intermediary between financial institutions, providing a neutral platform for sharing negotiable instrument transaction data. This intermediary layer enables real-time fraud detection by comparing transactions across institutions without requiring direct integration between each institution's systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a distributed ledger system is implemented to track negotiable instruments, then fraud detection is improved, but system complexity increases

Engineering Contradiction:

Improvefraud detection capabilityVSAvoidsystem architecture complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The distributed ledger system performs multiple functions simultaneously: it tracks negotiable instrument transactions, detects fraud in real-time, provides an immutable audit trail, and enables cross-institutional verification. This multi-functionality reduces the need for separate systems for each purpose, thereby managing complexity through consolidation rather than proliferation of separate systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables financial institutions to independently verify the status of negotiable instruments by querying the distributed ledger themselves. Each institution has the capability to perform verification without requiring manual intervention from other institutions or centralized authorities, reducing operational complexity while maintaining high reliability.

Inventive Principle:

Principle #25Self-service

3Reliability

If real-time verification of negotiable instruments is performed, then transaction security is enhanced, but processing speed may be reduced

Engineering Contradiction:

Improvetransaction securityVSAvoidtransaction processing speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary verification of negotiable instruments by checking the distributed ledger before finalizing transactions. This preliminary action identifies potential fraud indicators early in the process, allowing legitimate transactions to proceed quickly while preventing fraudulent ones from completing, thereby enhancing security without significantly impacting the speed of valid transactions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual, sequential verification processes with automated cryptographic verification through the distributed ledger. The blockchain's inherent consensus mechanisms and digital signature validation substitute for traditional manual checking procedures, providing real-time security verification while maintaining high transaction processing speeds through automated rather than manual operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
