00925njm 22002777a 4500 dc Muñoz-Guerra, Daniel Jesús author Constantinescu, Denisa-Andreea author Asenjo-Plaza, Rafael author Fuentes-Fernández, Lidia author 2019-06-25 Unified access to anonymous records through a trustworthy system is needed in our increasingly globalised world that still suffers from profoundly disconnected health care services. Emergencies are followed by redundant, costly and slow medical examinations without a global health data sharing mechanism. We establish the foundations of a decentralised healthcare ledger where patients decide what to share, with who, and with minimal costs. We review the state-of-the-art of transparent, auditable and interactive Blockchain-based healthcare studies, developing ClinicAppChain. Our solution features authentication, confidentiality and permissioned data sharing, considering the EU data protection regulation of 2018. ClinicAppChain is a cross-platform low-cost Blockchain prototype that empowers patients, hospitals, researchers, pharmaceuticals and insurance industries without crypto-currencies involved, and with a negligible energy foot-print (7.7 watts per node). 978-3-030-23813-1 2194-5365 https://hdl.handle.net/10630/40993 10.1007/978-3-030-23813-1_5 Blockchains Asistencia sanitaria Aplicaciones informáticas Ingeniería del software ClinicAppChain: A Low-Cost Blockchain Hyperledger Solution for Healthcare.
