Product authentication system based on blockchain

Product authentication system based on blockchain

Blockchain product authentication system:

System overview: The system uses blockchain technology to track the supply chain process of each product instance (such as each replica) and provide instant product authentication and enhanced user experience.

Technical field: It involves physical product authentication technology based on blockchain.

Product verification process:

Scan code: The user scans the code on the product through the user device to request product authentication.

Token determination: The token associated with the product instance is determined based on the scanned code.

Blockchain access: The system traverses the blockchain to access the data associated with the token and authenticates the product based on this data.

Token generation and transfer:

Token generation: A unique token is generated for each instance of the product, which is initially stored in a digital wallet.

Token transfer: As the product moves in the supply chain, the token is transferred between related entities and the corresponding transaction blocks are recorded on the blockchain.

Content generation and display:

Content generation: Entities and manufacturers in the supply chain can generate content (such as text, multimedia, augmented reality data) for product instances and associate these contents with tokens.

Content display: After successful authentication, the system displays enhanced content related to the product instance through the user device to provide a rich user experience.

Anti-counterfeiting and security:

Anti-counterfeiting detection: The system uses information such as device attributes, historical authentication requests, and geographic location to detect potential counterfeit products.

Security measures: Including the use of hash algorithms, digital signatures, multi-signature wallets and other technologies to ensure the security of tokens and transactions.

Enhanced user experience:

Interactive interface: The system provides an interactive interface to display the supply chain history and related content of the product.

Personalized experience: Provide personalized product information and experience through augmented reality technology.

System architecture and components:

Main components: Including user devices, service provider servers, manufacturer servers, supplier servers, product verification modules, etc.

Functional modules: The product verification module includes verification manager, minting module, authentication module, anti-counterfeiting detection module and content management module.

Application scenarios:

Automotive industry: Vehicles are tokenized and consumers prove ownership through digital wallets.

Cosmetics industry: Consumers exchange tokens for rewards or discounts.

Apparel industry: Verify the authenticity and ownership of clothing through blockchain.

Implementation details:

Private key management: The entity holds the private key of its own wallet and is responsible for passing tokens in the supply chain.

Transaction records: All transaction histories are stored in the blockchain transaction indexer and associated with the blockchain browser.

Entity registration: Register supply chain entities in a private or public blockchain network and assign wallets to them.

User interaction:

User interface application: Users interact with the system through the interface application installed on the user's device.

Geolocation acquisition: The user interface application obtains the geolocation information of the user's device through the geolocation component.

Describes how to use blockchain technology to achieve transparency in the product supply chain, efficiency in product authentication, and personalization of user experience, providing new solutions for combating counterfeit products and enhancing consumer trust.
