Security Mechanisms of a Mobile Health Application for Promoting Physical Activity among Older Adults

Physical activity contributes to the maintenance of health conditions and functioning. However, the percentage of older adults who comply with the recommendations for physical activity levels is low when compared to the same percentages on younger groups. The SmartWalk system aims to encourage older...
