Using forensic watermarks, the Edge server combats premium OTT content piracy.

Protecting content from leaks and illegal use is now more important than ever for companies offering video on demand and over-the-top services (VOD/OTT). To prevent illegal streaming and minimize damage, DRM protected content has been widely accepted by producers and distributors as an additional tool to deter illegal streaming. Using watermarking, you can make each viewing session’s video stream stand out from the rest. Bitstream modification, A/B watermarking, and client-side watermarking are three common methods of watermarking.

Any streaming player or device can benefit from session-based watermarking, which ensures that each individual user receives a unique copy of the content. video watermarking functions can be performed on the edge server because all streaming sessions are delivered from the CDN edge. New watermarking technology allows service providers to embed a watermark directly into the encoded bitstream, while the edge server uses a unique identifier to deliver content to users.

ABR transcoding is first performed on the video asset to be delivered before watermark pre-processing. Encoding a WMID becomes easier with this method of video inspection and identification of potential change points in the video stream (Watermark Identifier). When the bitstream is packaged, the information gleaned from this analysis is encoded as metadata.

The watermark token has been delivered: Prior to each viewing session, a WMID is requested by the video player. The content provider’s platform management subsystem creates a JSON web token that serves as a WMID.

When a video request is made, the edge server verifies the WMID token’s authenticity. If the compliance tests are successful, the WMID provided in the token is used to embed a watermark in the requested ABR video. Pre-watermarked videos are then released by the CDN so that each client receives their own unique video stream.

Using edge computing for bitstream watermarking reduces storage and bandwidth requirements while increasing video latency because it only requires one version of an asset to be watermarked. Leak detection and remediation can be made easier if the watermark can be found and extracted in advance.
