Smart room privacy

In this project, I investigated the threats to privacy posed by smart rooms (advanced home or office automation systems) and potential mitigations for these privacy threats.

Smart room (or smart space) systems have the potential to improve productivity and energy efficieny in many ways by adapting to us and anticipating our needs. However, to do so, the smart room system need to know us and know what's happening.

Our model of a smart room system is shown. It primarily consists of occupants (people), sensors, actuators, and a central computer.

Information leaks in smart spaces can be difficult to anticipate. For example, the lighting of a room may be set to match the preferences of the room's occupants; in this case, light leaking from the room carries information about the occupants, including information about their presence and their preferences. These elusive leaks can subvert access control mechanisms used to protect privacy.
