Recently, numerous systems for geo-tracking Alzheimer's patients with dementia have been developed and reported to be functional for the purposes of security and data collection. However, studies stated possible loss of freedom and autonomy for patients, along with violations of their privacy, which may lead to loss of prestige/dignity. In this study, a geotracking system that aims to balance patients' security and their need for privacy and autonomy is proposed. The system introduces a personalized, four-level temporal geofence based tracking, warning and notification protocol that incorporates a safety check mechanism operating over Global System for Mobile Communications network.
