  The digitization of the medical data has been a sensitive topic. In modern
times laws such as the HIPAA provide some guidelines for electronic
transactions in medical data to prevent attacks and fraudulent usage of private
information. In our paper, we explore an architecture that uses hybrid
computing with decentralized key management and show how it is suitable in
preventing a special form of re-identification attack that we name as the
re-assembly attack. This architecture would be able to use current
infrastructure from mobile phones to server certificates and cloud based
decentralized storage models in an efficient way to provide a reliable model
for communication of medical data. We encompass entities including patients,
doctors, insurance agents, emergency contacts, researchers, medical test
laboratories and technicians. This is a complete architecture that provides
patients with a good level of privacy, secure communication and more direct
control.
