Insecurities lurk beneath the surface of the fast-growing world of mobile healthcare, putting data at risk. But organizations can protect patient data by implementing a mix of technologies and best practices. The practice of using mobile devices in healthcare is growing. More than half -- 51% -- of physicians use tablets for professional purposes and 74% use smartphones at work. The mobile monitoring and diagnostic medical devices market will reach $8.03 billion by 2019, compared with a mere $0.65 billion in 2013, according to Transparency Market Research. This year alone 90 million wearable health devices will ship, reported ABI Research.
