Wandering is a common behavior during all stages of Alzheimer’s Disease (AD), but it can be distressing to both people with dementia and their caregivers. Ambient Assisted Living (AAL) solutions have been increasingly relevant to promote ageing in place, targeting both autonomous and dependent older adults. Despite the potentials of AAL solutions, their pervasiveness can raise several security and privacy challenges. With mobile mockups, this work presents a use-case with SoTRAACE - Socio-Technical Risk-Adaptable Access Control model, applied to the prevention of getting lost in AD. SoTRAACE functionalities are illustrated as embedded in an alarm navigation system aimed at monitoring the person’s geolocation and alerting when a predefined safety perimeter is crossed. The model, applied to a healthcare scenario, assesses security and privacy risks at each moment of interaction and provides an innovative way for improved adaptable security visualization in AAL environments.
