Abstract: The present invention discloses a method for the development of a system and method for authenticating products using a combination of blockchain technology, cryptographic verification, artificial intelligence, and QR-code based identification. A manufacturer registers a product by generating cryptographic hashes of product metadata that are stored on an immutable blockchain ledger while larger data remains in off-chain storage. Each product receives a unique QR code linked to its blockchain identity. During authentication, a consumer scans the QR code, cryptographically validates stored product information, uploads a product image for AI- based feature analysis, and receives a combined authenticity decision generated using blockchain verification, cryptographic integrity checks, image classification confidence, and supply-chain validation. The invention provides tamper-resistant, scalable, decentralized, and consumer-accessible authentication capable of significantly reducing counterfeit products. FIG.1
