Detection of Counterfeit Products with QR Codes using Blockchain Technology

Supply chain management commonly encounters challenges such as duplicate products and a lack of standardization due to insufficient transparency. This creates problem in the supply chain which takes up valuable time and resources. The presence of counterfeit products adds on to these issues, which are very difficult to distinguish visually from the real ones. This paper focuses on providing a solution to this already existing problem by implementing a QR based detection method which uses blockchain technology. The paper provides a thorough analysis of the current scenario of fake products present in the supply chain management system and proposes a novel method for robust detection. This is achieved using blockchain technology, which guarantees the traceability and identification of genuine products all the way through the supply chain. A Blockchain-based system decentralizes information, allowing multiple parties simultaneous access. Novel advantage of the proposed system is the difficulty of altering recorded data without the consensus of all concerned parties, providing a high level of security and protection against vulnerabilities. This system can be readily integrated into the supply chain to identify fake products that are often used for impersonation or fraud.
