CDN Performance Evaluation with Edge-Embedded Watermarking
Gwendal Simon, Gwenaël Doërr · 2023
Piracy of copyrighted video content is an everlasting concern for copyrights holders, such as major studios who want to protect their latest movies/series or video distributors who want to safeguard their exclusive rights investments. To prevent piracy, the video technology providers have designed solutions based on the concept of watermarking, i.e., the video frames contain marks, which can be reliably extracted by a watermark extractor, while remaining invisible for the human eye. Yet, distributing watermarked streams is hard to scale in practice: to prepare and deliver a unique watermarked stream to each user, the service providers should implement a specific system in their Content Delivery Network (CDN) [3].
