The document discusses how big data and Hadoop can help address challenges in healthcare and fulfill key wishes or goals. It outlines common healthcare challenges like overdependence on manual caretaking and lack of continuous remote patient monitoring. Key wishes are reducing unnecessary doctor visits, anticipating patient conditions, knowing best nearby facilities, and preventing billing fraud. Hadoop allows storing all healthcare data in its native format and integrating data from devices via the Internet of Things. This enables improved remote patient monitoring, real-time recommendations on care and facilities, and a more holistic view of patients and the healthcare system. An encryption demo is also provided.
