Data Access Control Based on Blockchain in Medical Cyber Physical Systems

The current medical cyber physical systems involve a wide range of institutions and a large number of participants. Data sharing among distributed medical institutions is already a development trend. However, the security is worrying; e.g., the access to medical data lacks uniformity and standardiza...
