Identification of fraudulent products using blockchain technology

Fraudulent products pose a significant threat to consumer safety, brand reputation, and global economic stability. Traditional product authentication technologies struggle to offer tamper-evident and scalable functionalities, especially in the modern digital economy. This paper proposes Digi Seal, a product authentication system based on blockchain technology that offers secure, open, and efficient tracking of products from manufacturers to consumers. On top of Ethereum and smart contracts, using QR code scanning and role-based access, the system offers product registration, authentication, ownership transfer, and reporting counterfeit. The paper outlines Digi Seal design, development, implementation, and testing, illustrating how blockchain technology can effectively be used to combat counterfeiting.
