Smartphone-based continuous blood pressure monitoring application - robust security and privacy framework

Smartphone-based applications have developed over time with remarkable sophistication and user attraction. At the same time, a need for remote storage and user management becomes obvious and important among other challenges of the mHealth domain. The main purpose of this research is to facilitate continuous monitoring of vital signs and blood pressure without the use of a blood pressure cuff. We selected an Android platform and connected a pulse oximeter (Oxygen Saturation), and a 2-lead Electrocardiogram (ECG) device to the application. An algorithm involving pulse transit time and QRS detection was developed to continuously measure blood pressure and some other vital signs. Three key highlights of the proposed application are: security and privacy framework; using cloud for storing recorded data and history information or, more specifically, a back end as a service; and cuff less continuous blood pressure measurement. A successful application was developed for continuous blood pressure monitoring with reasonable accuracy and standard security framework.
