Performance evaluation using throughput and latency of a blockchain-enabled patient centric secure and privacy preserve EHR based on IPFS

Abstract

Every nation needs a better healthcare system and services for general people for digital medical records, which are available on a large scale. However, patients' health data is too sensitive to share and unsecured to store on centralised storage. However, it is required to ensure security and privacy with better storage and retrieval methods for PEHR (Patient Electronic Health Record). Blockchain allows for the secure and effective exchange of PEHR in a decentralised, tamper-proof manner and traceable distributed ledger that stores using Hyperledger Fabric (HLF) framework in encrypted form on the InterPlanetary File System (IPFS). The hyperledger caliper benchmark measures the blockchain network's performance concerning transaction throughput and latency. This paper discusses the performance evaluation of a Blockchain-Enabled Patient Centric Secure (BEPCS) and privacy preserved electronic health record on IPFS. It proposes a strategy that may increase throughput by 5-10% and decrease latency by 5-10% with better security and privacy.
