Applications of trusted computing in pervasive smart camera networks

Pervasive Smart Cameras are embedded computer vision systems bringing together the research areas of smart cameras and wireless sensor networks. Besides traditional areas like video surveillance or traffic monitoring, small, cheap and powerful camera systems open a wide range of potential new applications including assisted living, home automation or entertainment. At the same time, widespread deployment of cameras introduces several security challenges. Using wireless networking and being mounted at remote locations, smart cameras are an attractive target for attackers. Another issue of crucial importance when it comes to the acceptance of camera systems is user privacy. In this work we explore the use of Trusted Computing concepts to enhance security of an experimental smart camera system. Additionally, we discuss required and achievable performance based on evaluations on our prototype platform.
