Authorized Shared Electronic Medical Record System with Proxy Re-Encryption and Blockchain Technology

With the popularity of the internet 5G network, the network constructions of hospitals have also rapidly developed. Operations management in the healthcare system is becoming paperless, for example, via a shared electronic medical record (EMR) system. A shared electronic medical record system plays...
