Consensus Mechanisms for sharing healthcare data using Blockchain Technology

Abstract

newlineHealthcare information exchange is an important research topic that can benefit both newlinehealthcare providers and patients. In healthcare data sharing, many cloud-based newlinesolutions have been proposed, but the trustworthiness of a third-party cloud service is newlinequestionable. Recently, Blockchain has been introduced in healthcare record sharing, newlinewhich does not rely on trusting a third party. However, existing approaches only focus newlineon the records collected from medical examinations. The majority of medical devices newlinebased on current centralized server data management technology don t give any newlineguarantee of authenticity and security. The collected data are shared with laboratories newlineand institutions for diagnosis and further study. Blockchain is a public tamperproof newlineledger that is a decentralized network system in which data transactions are newlinedistributed among the nodes. The combination of Blockchain technologies with a newlineconsensus algorithm can become the best choice for designing secured distributed ehealthcare newlinesystems. newline
