In response to the global challenge of counterfeit products, this paper presents an advanced anti-counterfeit system leveraging blockchain technology. The system utilizes Ethereum, Solidity, and Ganache to establish an immutable and transparent ledger, enabling real-time tracking of products from manufacturer to consumer. Manufacturers register their products on the blockchain, generating unique QR codes with Copy Sensitive digital images for secure identification. Consumers employ an Android application to scan these QR codes, decrypting the encrypted text to access vital information about product authenticity. This system not only empowers consumers with instantaneous verification but also provides businesses with a robust defense mechanism against counterfeit threats, safeguarding their reputation and revenue. The integration of innovative technologies revolutionizes the authentication process, instilling trust in consumers and bolstering brand integrity. Our solution stands as a pioneering force in the battle against counterfeit production, offering a scalable and efficient method for detecting fake products using blockchain technology. Key Words: Block chain, smart contracts, QR(Quick Response) code, anti- counterfeit.
