RFID and Smart Chip Product Authentication via Blockchain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for online shopping has led to issues with package integrity during shipping, including theft, vandalism, and fraud, as existing methods like signature verification and tamper-proof seals are inadequate, and there is a need for a reliable method to track products from manufacturer to end-user.
Innovation Solution
A method utilizing a package with a printed label and an electronic tag containing a product identifier, paired with a smart chip that generates an encoded value using a digital key, recorded in a blockchain ledger, allowing for authentication and tracking of the product throughout the delivery chain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signature verification is used for delivery confirmation, then delivery accountability is improved, but it cannot prevent theft or fraud when recipient is absent
Solution Approach 1:
The patent applies preliminary action by embedding authentication mechanisms (electronic tags and smart chips) into the package before delivery. These mechanisms pre-establish verification capabilities that work automatically during transit and delivery, eliminating the need for recipient presence or manual signature verification while preventing theft through continuous authentication tracking.
Solution Approach 2:
The patent introduces electronic tags and smart chips as intermediary elements between the package and the verification system. These intermediaries carry authentication data and enable verification without direct human intervention, acting as mediators that bridge the gap between physical delivery and digital verification while preventing fraud.
2Stability of the object's composition
If tamper-proof seals are used to prevent package opening, then package integrity is improved, but they cannot verify product authenticity
Solution Approach 1:
The patent merges two separate functions into a unified authentication system: tamper-evident sealing and product authenticity verification. The electronic tag and smart chip serve dual purposes - they detect package opening (integrity monitoring) and verify product identity (authenticity confirmation), eliminating the need for separate mechanisms.
Solution Approach 2:
The electronic tag and smart chip are designed as multi-functional elements that perform multiple tasks: tracking package location, detecting tampering, verifying product authenticity, and enabling delivery confirmation. This universal approach replaces multiple separate systems with a single versatile authentication mechanism.
3Loss of information
If electronic tags with product codes are used for verification, then product tracking is improved, but they can be replicated or forged
Solution Approach 1:
The patent replaces simple mechanical or magnetic stripe tags with sophisticated smart chips containing cryptographic authentication mechanisms. These chips use secure elements and encrypted verification protocols that are computationally difficult to replicate, substituting basic electronic identification with cryptographically secure authentication.
Solution Approach 2:
The patent changes the verification parameter from simple product code matching to cryptographic hash verification. The smart chip generates and stores cryptographic hashes of product identifiers, and verification involves comparing these hashes against blockchain records, making forgery extremely difficult without the original cryptographic keys.
4Reliability
If blockchain technology is implemented for end-to-end tracking, then transparency and trust are improved, but system complexity increases
Solution Approach 1:
The patent segments the blockchain implementation into modular components: smart contracts for authentication logic, distributed ledger for data storage, and API interfaces for system integration. This segmentation allows different parts of the supply chain to adopt blockchain at their own pace and complexity level while maintaining overall system transparency.

Function Achieved in This Case
Ensures the integrity and authenticity of the product by allowing validation at any point in the delivery chain, preventing tampering and fraud, and providing a reliable tracking mechanism from manufacturer to end-user.
Implementation Method 1
The electronic tag may for example be a radio-frequency identification marker

AI summary
Trustable delivery of a product uses a package with a printed label having a unique product ID, an RFID marker applied to the product that contains the ID, and a smart chip inside the product that contains the ID and a digital key. The ID from the RFID marker is compared to the label for initial validation of the package. The smart chip is further interrogated to generate an encoded value of the ID, such as a hash value, using the digital key. The hash value is then used to authenticate the ID, thereby verifying that the product as delivered is the original, untampered product. The product ID and the hash value are recorded in a blockchain ledger associated with the product. In this manner, the packaged product can be validated by any party in the delivery chain, e.g., manufacturer, seller, distributor, delivery service, and final recipient.
