Blockchain Based Counterfeit Medicine Authentication System

For a few decades, it is a very big challenge to monitor and keep track of genuine medicine in health care. Lacking a trust system and strong monitoring authority, syndicates can make counterfeit medicine easily. With the shifting of life-critical healthcare, it becomes an emergency to ensure substandard drugs. Because counterfeit medicine has a deadly effect on the human body and has disastrous results. To detect the falsified medicine, we proposed a drug tracing system using blockchain technology. Our system is able to detect substandard and anomaly drugs from manufacturer company to patient's hand. Also can verify the defective and expired drugs in the market using smartphones by scanning QR (Quick Response) code. Blockchain security could make the system more transparent and reliable. This paper aims to ensure drug quality, transaction security, and data safety using blockchain technology.
