Abstract
In the current scenario, healthcare organizations are facing a serious problem in sharing medical information among different stakeholders without sacrificing the privacy and integrity of information. To store and share such a large volume of healthcare information securely is an important research issue. Blockchain has been used successfully in the bitcoin for the decentralized exchange of cryptocurrency without the involvement of the third party. The new structure of blockchain has been designed to accommodate the need of another field such as healthcare. Blockchain technology has the potential of immutability, integrity and decentralized architecture to manage the health records of the patient. This paper aims to address the issues of data security and authentication in healthcare. We have proposed a blockchain based secure framework using public key cryptography.
