Blockchain based Medical Data Asset Management System

In today’s health care management, medical health records are in the form of electronic medical record (EHR/EMR) systems. These systems store a patient’s medical history in a digital format. However, a patient’s medical data being acquired in an efficient and timely manner is proven to be difficult through these records. Health management is always hindered by the inability to acquire information, less usage of information acquired, unmanageable privacy controls, and poor data asset security. In this paper, we are introducing an efficient as well as a secure medical data asset management system using blockchain in order to resolve these issues. Blockchain technology eases the accessibility of all such records by maintaining a block for every individual patient. This paper proposes an architecture using an off-chain solution that will enable doctors, and patients to access records in a safe way. Blockchain makes medical records immutable and encrypts them for data integrity. Users can observe their health records, but only patients own the private key and can only share it with whom they desire. The smart contracts also help our data owners to manage their data access in a permissioned manner. The final result will be viewed as a web and mobile interface to easily access, detect as well as ensure high-security data.
