Blockchain-based patient-driven Inter-OperableModel for healthcare 5.0 system

Abstract

With the rise of powerful computational technologies, healthcare systems are going through a paradigm shift to the era of healthcare 5.0, also known as" smart healthcare". This new-age healthcare system not only enhances the life of patients but also aims to reduce healthcare costs significantly. People's health data is too sensitive to be regulated by particular organizations owing to the increasing threat to privacy and security. The sheer size of data makes it difficult for centralized bodies to regulate, due to which 3rd party involvement is introduced, which again poses threats to the privacy of data holders. Motivated by the abovementioned gaps, we propose a decentralized approach using Ethereum blockchain technology and Oasis protocol. The patient-driven solution approach effectively solves the privacy problem by providing full control of data to the owner. Along with this, byproducts such as fine-grained access control and on-chain data processing capabilities are also obtained.
