The major advances in body-mounted sensors and wireless technologies have been revolutionizing the healthcare industry, where patient conditions can be monitored remotely by medical staff. Such a model is gaining broad support due to its economic and social advantages. The wealth of sensor measurements, however, pose major technical challenges on where to store the collected data, how to ensure their integrity, who controls access permissions, and how to enable secure interaction between patients and medical facilities and professionals. This talk provides a holistic solution based on blockchain technology. Our solution puts the patient in charge for granting and revoking access permissions and makes it easy for healthcare organizations and providers to meet privacy regulations. Sensor data reside on cloud storage, while access control and session logs are maintained on a blockchain. In addition, we propose a novel data-driven authentication and secure communication protocol to mitigate the risk of fraud and identity theft. To enforce such a protocol, healthcare providers, and all interactions between the cloud and patients, are regulated through smart contracts. We show our solution is computationally efficient and analyze its security properties using the AVISPA (Automated Validation of Internet Security Protocols and Applications) toolset.
