Solution Overview

Problem

Current custom clearance solutions face challenges with high regulatory costs, data inconsistencies, and fraud due to loopholes in systems, making it difficult for customs authorities to verify and process international shipment data accurately and securely.

Innovation Solution

A blockchain-based custom clearance service platform that encrypts and stores data on a blockchain network, using smart contracts to manage authorized access and ensure data integrity and privacy, while linking order, logistics, and payment data for transparent and immutable record-keeping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If data is stored in centralized systems for custom clearance, then processing speed may be improved, but data integrity and security deteriorate due to manipulation risks and fraud

Engineering Contradiction:
Improveprocessing speedVSAvoiddata integrity
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent segments the centralized custom clearance system into a distributed blockchain network where multiple nodes independently verify and store data. This segmentation prevents single-point manipulation while maintaining processing efficiency through parallel verification across the network.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces smart contracts as intermediary automated programs that mediate between different parties in the custom clearance process. These self-executing contracts ensure data integrity by automatically enforcing predefined rules and conditions, eliminating manual intervention risks.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If traditional custom clearance systems are used, then implementation simplicity is maintained, but regulatory costs increase due to manual verification and data inconsistency

Engineering Contradiction:
Improvesystem simplicityVSAvoidregulatory costs
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent implements self-service functionality through smart contracts that automatically execute custom clearance operations without manual intervention. The system autonomously verifies data consistency, validates shipping information, and processes clearance decisions, eliminating costly manual verification processes while maintaining operational simplicity through standardized protocols.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If data from multiple sources is aggregated for custom clearance, then comprehensive information is achieved, but data consistency deteriorates due to inconsistencies across sources

Engineering Contradiction:
Improvedata completenessVSAvoiddata consistency
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent merges data from multiple sources (merchants, logistics providers, payment processors) into a unified blockchain ledger. All parties contribute their respective data to the same distributed ledger, ensuring that everyone accesses and processes identical information, thereby eliminating consistency issues while maintaining comprehensive data coverage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements feedback mechanisms where the blockchain network continuously verifies and validates data from multiple sources against predefined criteria. Any inconsistencies trigger automatic validation processes and alerts, ensuring data quality is maintained throughout the aggregation process.

Inventive Principle:
Principle #23Feedback

AI summary

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for managing user authorizations for blockchain-based services. One of the methods includes: at a service platform, receiving, from a computing device associated with a user, an encryption key and data for storage on a blockchain, wherein the data includes public data and private data, and the encryption key encrypts the private data; storing the encryption key and an identifier (ID) of the data in a cache storage dedicated to storing smart contract data for executing a smart contract; and invoking an application programming interface (API) to en able a blockchain node to initiate a consensus algorithm to record the data and the ID of the data on a blockchain.
