Management of medical record data with multi-level security on Amazon Web Services.

Blockchain technology has gained significant attention in the most recent years due to its potential to address related issues to privacy, transparency, and security. In the healthcare industry, it is considered a promising solution to challenges related to data management, medical data privacy, and security. This paper proposes a novel framework for managing electronic medical healthcare records that uses Amazon Web Services (AWS) to create a secure and cost-effective solution. The proposed solution uses a serverless approach to reduce costs and only pay for the compute resources when needed. The framework focuses on improving the security of access to the blockchain network by implementing a multi-level security approach, starting from protecting the Hyperledger and implementing role-based access for end-users who require access to the stored data. The effectiveness of the proposed framework is demonstrated by creating a role-based access matrix for three different user types and performing multiple experiments to validate access for each user type.Article highlights: Secured Hyperledger blockchain network using Amazon Web Services. Serverless solution for the API layer using Amazon Lambda function and API gateway and secured using Amazon Cognito. Three members in the network to support separation of concerns between medical facility, patient and enforcement authority. [ABSTRACT FROM AUTHOR]
