A Distributed Storage System for Robust, Privacy-Preserving Surveillance Cameras

Surveillance cameras have been extensively used in smart cities and high security zones. Recent incidents have posed a new, powerful geo-range attack, where the attacker may compromise a group of surveillance cameras located within an area. To tackle the problem, we develop a distributed camera storage system that distributes video content across geographically dispersed surveillance cameras. It generates secure copies for the video content and enhances robustness by judiciously distributing erasure coded video blocks across optimally-chosen surveillance cameras. We implement the distributed storage system for surveillance cameras and evaluate its performance via real-world field test. Our system is the first solution that can defend against geo-range attacks in a robust and privacy-preserving manner.
