Securing Healthcare Data by Using Blockchain

Healthcare is an important aspect of the development of the nation, and healthcare data are a key element in curing patient health. Healthcare information exchange is a very important aspect that benefits patients as well as health service providers. Due to a large amount of patient data, service providers use many cloud-based solutions, but insecurity arises in the case of the third-party service provider. This issue has been addressed by the authors in this chapter. However, existing techniques mainly focus on collecting patients’ records from medical examination. In the present, IoT is widely used in mobile applications for monitoring patient’s health and maintaining records. Then, collecting records could be sent to laboratories for further analysis and diagnosis. But, present techniques are too rigid in exchange of metadata. Authors tried to develop a method using smart contracts in blockchain which helps in securing the data over transfer. Each and every aspect of healthcare has been taken into consideration including the lab results, clinical trials, reimbursements, medical charts, etc. In this chapter, the role of blockchain in making digital records and transfer of the same in the healthcare system safe and encrypted is discussed. Different technology used for managing healthcare data is also discussed in this chapter. Later on, the use of smart contracts in blockchain and migration of the existing model of healthcare system into blockchain is discussed. Based on the proposed model, result evaluation is discussed for securing healthcare data using blockchain.
