Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional commercial RFID shipping systems face issues with counterfeit items and language translation barriers when shipping internationally, as RFID data is often not translated accurately across different languages, leading to potential misappropriation and lack of secure tracking.
Innovation Solution
A blockchain-based universal RFID translator system that decrypts, translates, and encrypts RFID data, ensuring immutability, security, and decentralized storage, thereby creating a verifiable chain of custody and preventing counterfeit swapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional RFID tracking is used, then item tracking is achieved, but security against counterfeit swapping is insufficient
Solution Approach 1:
The patent introduces a blockchain-based intermediary layer between RFID tags and tracking systems. This intermediary maintains an immutable ledger that records all RFID tag readings and item movements, creating a verifiable chain of custody that prevents counterfeit swapping by providing cryptographic proof of authenticity at each supply chain stage.
Solution Approach 2:
The patent creates cryptographic copies (hashes) of RFID tag data and stores them on the blockchain. These cryptographic copies serve as immutable records that can be verified without exposing the original sensitive data, enabling security verification while maintaining tracking reliability.
2Measurement precision
If RFID data is stored in original language, then data accuracy is maintained, but international translation and accessibility are hindered
Solution Approach 1:
The patent introduces language translation as an intermediary process within the blockchain system. Original RFID data is stored in its source language on the blockchain, while translation services act as intermediaries that convert the data into other languages without altering the original record, thus maintaining data accuracy while improving international accessibility.
Solution Approach 2:
The blockchain system serves multiple functions simultaneously: it stores original data, maintains cryptographic verification, and supports multi-language translation. This universal platform handles both data preservation and international communication needs, resolving the contradiction between accuracy and accessibility.
3Reliability
If blockchain is used for secure storage, then data security and immutability are improved, but system complexity increases
Solution Approach 1:
The patent segments the system into distinct layers: RFID tag layer, blockchain ledger layer, and translation/application layer. Each layer handles specific functions independently, reducing overall system complexity while maintaining security. The blockchain layer specifically handles secure storage and verification, while other layers handle translation and user interaction.
Solution Approach 2:
The patent introduces intermediary components such as smart contracts and translation services that mediate between the blockchain and users. These intermediaries simplify the interface complexity by handling cryptographic operations and language translations automatically, allowing users to interact with the secure blockchain system without dealing with its inherent complexity.
