Security and Privacy for Healthcare Blockchains

Healthcare blockchains provide an innovative way to store healthcare information, execute transactions, and build trust for data sharing integration in a decentralized open network environment. Although the blockchain technology has attracted broad interests attention industry, government academia, security privacy concerns remain focus of debate when deploying information sector from business operation research collaboration. This article focuses on requirements medical using blockchain, provides comprehensive analysis risks requirements, accompanied by technical solution techniques strategies. First, we discuss attributes required electronic blockchain. Second, categorize existing efforts into three reference usage scenarios sharing, technologies implementing these properties categories such as anonymous signatures, attribute-based encryption, zero-knowledge proofs, verification smart contract security. Finally, other potential application sector. We conjecture that this survey will help professionals, decision makers, service developers gain intuitive insights terms concepts, risks, development deployment systems.
