System for blockchain-based verification and tokenization of physical products using unique product identifiers, NFC technology, and digital fingerprinting for end users (consumers)

Abstract

System for the verification of physical products using blockchain based on product identification (barcode, QR code, UDI) with or without NFC

Description

Appendix 1Technical Protection Document - General Tokenization and Verification SystemTitle of the invention:

[0001] System for blockchain-based verification and tokenization of physical products using unique product identifiers, NFC technology and digital fingerprint for end users (consumers)- Technical area:

[0002] Blockchain technology, product protection, anti-counterfeiting, supply chain, tokenization, cryptocurrencies, IoT, medical technology, luxury goods.

[0003] The invention relates to a system for the digital verification, traceability, and authenticity testing of physical products, in particular medical products. The system combines physical identification technologies (e.g., NFC, QR code, UDIs, fingerprint sensors, biometric data) with blockchain technology, with or without digital tokens, to enable forgery-proof and decentralized traceable product identification. The goal is to meet the requirements of modern systems regarding product safety, user interaction, and regulatory tracking in the healthcare sector, among others. Background and problem:

[0004] Counterfeiting of physical products—whether medical devices, luxury goods, electronics, or spare parts—is a global problem. Current solutions rely on QR codes, barcodes, central databases, or serial numbers, which are easily copied or manipulated. At the same time, the need for digital ownership verification (tokenization) is growing, both for companies and end users (consumers). Aim of the invention:

[0005] Providing a system for secure verification and tokenization of physical products by combining: - unique product data (e.g. serial numbers, barcodes, UDIs) - NFC technology - digital fingerprint - and blockchain / NFT technology enables a forgery-proof product identity, traceability and a tradable digital representation (token). Solution:

[0006] The system includes three tiered security levels and can be applied to all types of physical products. Security Level 1 - Basic Verification (Data Hash) - System *) for the integration of existing product identifiers via user-side input modules (e.g. QR code, serial number, GS1, RFID, UDIs) by the manufacturer or user, the product identifier is affixed to the product and / or packaging. - Generation of a hash value - Storing the hash value on a blockchain (Ethereum, Polygon, etc.) - Verification via app scan of the barcode, hash comparison with the blockchain. - Bonus program and rating system possible after successful verification of the product. - Counterfeit-proof thanks to verification via blockchain - Security level: Medium Security Level 2 - NFC + Fingerprint - In addition to security level 1: the product contains a unique / coded / serialized NFC tag optionally with barcode (e.g. QR code, UDI, serial number). - System component for automated hash generation from NFC and barcode data → fingerprint and stored on the blockchain. - System component for verification via NFC scan within a mobile application (with or without barcode), hash comparison with the blockchain. - Bonus program and rating system possible after successful verification. - Counterfeit-proof thanks to physical component - Security level: high to very high Security Level 3 - Tokenization / Non-Functional Token (NFT) - In addition to security level 2: Combination of NFC and barcode data → hash → NFT on the blockchain. - System for performing a comparison between the physical product authentication structure (NFC + barcode) and the stored NFT identity data record within a mobile or stationary device. The system compares NFT data with the physical product or the hash value on the blockchain. - Each verified product can optionally be represented as an NFT (Non-Fungible Token): - Proof of ownership - Right of use - Contractual commitment (e.g. leasing, guarantee) - NFT standards: ERC-721 or ERC-1155 or others - Tradable on compatible markets or within your own infrastructure - Bonus program, proof of ownership, reviews and digital interactions possible. - Security level: Very high *)System here also means access to existing databases (EUDAMED etc.) Bonus and rating system (valid for all levels) - Users can collect points and rate products after successful verification. - Manufacturers receive feedback, customer loyalty is strengthened. - Bonus and rating are linked to hash / NFT in a forgery-proof manner.

Recalls are documented transparently and visible to end users in real time. Manufacturers can recall specific devices or batches. Transparency for authorities and users Can be combined with IoT, AI, audit systems Flexible use in a wide range of industries
