Blockchain-Based Secured Drug Traceability in Health Care Application

Despite the enormous advancements in technology, fraudsters continue to attack the healthcare industry. Numerous recent healthcare security breaches indicate that attackers are focussing on the electronic health data and the drug supply chain. Additional investigation into security problems in the healthcare sector demonstrates that the primary cause of these incidents is the centralisation of data storage. The healthcare sector also lacks immutability, adaptability, security, and privacy in addition to having insufficient documentation. It has been discovered that blockchain technology may offer a complete solution to the main issues the healthcare industry is now facing. Healthcare issues may be resolved with the aid of blockchain's intrinsic qualities, which include immutability, transparency, privacy, security, and documentation. In this work, an interactive blockchain 2.0 medication supply chain tracking system is created, and Hyperledger Calliper is used to measure the system's performance. This system makes sure that everyone involved in the drug supply chain can follow the drug's journey from the producer to the end user. The members' own inventory management is also aided by it. In addition to providing privacy and transparency, this method offers a viable remedy for the issues associated with counterfeit drugs. With one ordered peer and one endorsed peer, the system can process 25,000 transactions per second.
