A platform for secure monitoring and sharing of generic health data in the Cloud

• We combine smartphone, Bluetooth and the Cloud to enable mobile telecare.
• We develop a smartphone app that remotely monitors patients for cardiac arrhythmias.
• We propose our secure data sharing protocol between patient and doctor in the Cloud.
• We provide a security analysis of our model, protocol and prototype.
• We evaluate the prototype to test for feasibility of use in the real world.

The growing need for the remote caring of patients at home combined with the ever-increasing popularity of mobile devices due to their ubiquitous nature has resulted in many apps being developed to enable mobile telecare. The Cloud, in combination with mobile technologies has enabled doctors to conveniently monitor and assess a patient’s health while the patient is at the comfort of their own home. This demands sharing of health information between healthcare teams such as doctors and nurses in order to provide better and safer care of patients. However, the sharing of health information introduces privacy and security issues which may conflict with HIPAA standards. In this paper, we attempt to address the issues of privacy and security in the domain of mobile telecare and Cloud computing. We first demonstrate a telecare application that will allow doctors to remotely monitor patients via the Cloud. We then use this system as a basis to showcase our model that will allow patients to share their health information with other doctors, nurses or medical professional in a secure and confidential manner. The key features of our model include the ability to handle large data sizes and efficient user revocation.
