In this paper, we present an online platform for the field of Ambient Assisted Living (AAL) which is designed to support a self- determined and safe life for elderly people in their own homes instead of admission to a nursing home. This goal is achieved through in-home monitoring of the clients using wireless sensor networks in combination with a social networking approach based on personal Patrons. The platform further acts as a marketplace for third party service providers which can extend the functionality of the platform, supplying the users with individual made-to-measure assistive services. This paper provides an overview of the concept behind this platform with special focus on privacy issues.
