Security and Privacy in Distributed Smart Cameras

Distributed smart camera systems are becoming increasingly important in a wide range of applications. As they are often deployed in public space and/or our personal environment, they increasingly access and manipulate sensitive or private information. Their architectures need to address security and privacy issues appropriately, considering them from the inception of the overall system structure. In this paper, we present security and privacy issues of distributed smart camera systems. We describe security requirements, possible attacks, and common risks, analyzing issues at the node and at the network level and presenting available solutions. Although security issues of distributed smart cameras are analogous to networked embedded systems and sensor networks, emphasis is given to special requirements of smart camera networks, including privacy and continuous real-time operation.
