dc.description.abstractWe show that information leakage occurs in video over IP traffic, including for encrypted payloads. It is possible to detect events occurring in the field of view of a camera streaming live video through analysis of network traffic metadata including arrival time between packets, packets sizes, and video stream bandwidth. Event detection through metadata analysis is possible even when common encryption techniques are applied to the video stream such as SSL or AES. We have observed information leakage across multiple codes and cameras. Through timestamps added to the x264 codec, we establish a basis for detectability of events via packet timing. Laboratory experiments confirm that this event detection is possible in practice and repeatable. By collecting network traffic captures from over 100 Skype video calls we are able to see the impact of this information leakage under a variety of conditions.
