Security framework for visual sensors and smart camera networks

The development of wireless sensor networks and constant increase of their capabilities enabled the integration of image capturing device within sensor node, representing the basis for visual sensor network. Such smart camera is primarily used for converting visual data into knowledge. The paper analyzes security requirements of visual sensor networks and describes possible security threats and attacks, while also suggesting possible countermeasures. Security framework for possible application on visual sensor networks and smart cameras is also proposed, and its components are explained. Finally, some conclusions are derived and suggestions for future development are given.
