mHealth – what’s different?• Security
• Immediate, personal impact • mHealth devices directly affect your health, or health decisions
• Privacy • Sensitivity of data:
• mHealth data is inherently personal, literally about you • Volume of data:
• mHealth collects far more medical data, over extended periods • Diversity of data:
• mHealth collects a broader range of information, including lifestyle, activities, and context
• Uses of data: • mHealth enables a broad range of apps, outside the doctor-patient relationship
