Priva-Stream: Private Collaborative Live Streaming

Abstract : Video streaming currently accounts for more than 75% of overall Internet traffic. However, Content Delivery Networks, which are commonly used to deliver video content, are costly to setup and do not scale well for live video streaming services. We introduce Priva-Stream, an edge-assisted content delivery system allowing to aggregate video content from multiple edge peers in addition to existing delivery servers. Priva-Stream uses incentive mechanisms to reward participating users, and trusted execution environments such as Intel SGX to enforce privacy. Our experiments using a complete prototype show that Priva-Stream increases the quality of experience end-users can expect while at the same time providing strong privacy guarantees.
