Solution Overview

Problem

Current custom clearance solutions face challenges with high regulatory costs due to inconsistent and manipulated data from various sources, leading to fraudulent claims and tax evasion, with a need for a unified, transparent, and verifiable platform that ensures data integrity and privacy.

Innovation Solution

A blockchain-based system for custom clearance data processing that includes encrypting data, using smart contracts, and consensus algorithms to store and manage data securely, ensuring data integrity and privacy, and implementing a scalable storage solution with smart contract pools and blockchain databases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If data from multiple sources is collected for custom clearance, then the volume of transactions increases and more information is available, but data inconsistency and manipulation make it difficult to process and review

Engineering Contradiction:
Improvevolume of custom clearance dataVSAvoiddata consistency and integrity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent merges data from multiple sources (merchants, consumers, logistics providers, customs authorities) into a unified blockchain ledger. All parties contribute their respective data (order information, payment data, logistics tracking, clearance status) which are then consolidated into a single immutable record, eliminating data inconsistency while maintaining the ability to process high volumes of transactions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The blockchain network acts as an intermediary between multiple data sources and customs authorities. Smart contracts serve as automated intermediaries that verify and validate data from different parties before recording it on the ledger, ensuring data integrity without requiring manual review of each transaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If traditional custom clearance systems are used, then processing can be performed, but fraudulent claims and tax evasion are difficult to detect due to manipulated data

Engineering Contradiction:
Improvecustom clearance processingVSAvoiddetection of fraudulent claims
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements feedback mechanisms where each party in the supply chain (merchants, logistics providers, customs authorities) continuously updates their status on the blockchain. This creates an audit trail that provides real-time feedback on transaction authenticity, enabling automatic detection of discrepancies or fraudulent patterns through smart contract validation rules.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Data is validated and verified through smart contracts before being recorded on the blockchain ledger. This preliminary action of verification ensures that fraudulent or inconsistent data is rejected before it can be used for clearance processing, preventing tax evasion and fraudulent claims at the source rather than detecting them later.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If data is stored in traditional centralized systems, then access and processing are straightforward, but data privacy and integrity cannot be ensured against manipulation

Engineering Contradiction:
Improvedata access and processingVSAvoiddata privacy and integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system segments data into different layers: sensitive personal information is encrypted and stored privately, while verification hashes and metadata are stored on the public blockchain. This segmentation allows easy access to verification data while protecting private information, maintaining operational ease while ensuring data integrity and privacy through cryptographic proofs.

Inventive Principle:
Principle #1Segmentation
