Blockchain technology enables privacy, security, audit-ability, tracking and monitoring in a real world transactional systems. Due to its features in various other industries block chain has also being implemented. One of such essential application is found in Supply Chain Management (SCM). In this paper the block chain technology implementation has been explored in healthcare industry. The aim of applying the block chain technology is to recognize a hospital patient uniquely and settle the insurance claim automatically, securely and efficiently. In this context, first an algorithm has been introduced, which utilizes the user smart phone and government assigned ID to create a unique ID. The unique ID is stored and utilized with the user’s smart mobile. After creation off identity the same ID is used to authenticate the transactions. In order to verify the transactions the mobile is used to create a signature which is submitted to the insurance company. The signature has used to verify the transaction performed by the patient to the hospital as claiming the insurance. The simulation of the proposed bock chain based system has been performed by using the JAVA technology. After implementation the experiments with the simulation has been carried out and performance has been measured. The performance for both the situations certificate creation and authentication has been measured based on time and memory utilization. The obtained performance shows the efficiency, security and confidentiality in managing transactions in health care system.
