Electronic medical record security and access control using blockchain and IPFS

Abstract

An EMR or electronic medical records typically contains minor to sensitive medical data of a patient including their personal information, doctors' provided prescription and other physical history. Switching to this digital method from traditional reports indeed reshaped the health sector in a better way along with arising the risk of losing security. Ensuring full protection of these signi cant data and strengthen access control takes a ne level of structured system. To preserve the authentication, privacy and integrity of medical data in EMR systems, we came up with a model. We propose a patient centric EMR system based on blockchain technology where data are encrypted and stored in two-layered protective cloud storage. To access any data or report, physicians will be veri ed with digital certi cates and provided permission by patient. Main purpose of this model is to serve a strong level of security to data and preserving them in a cost effective way.
