Distributor Watermarking : Insure against pre and post release piracy threat landscape
Streaming has taken over as the most popular method of content consumption today. The volume and scope of content piracy has grown as a result. In order to identify the source of infringement and limit access to premium content, studios, OTT providers, and content owners now absolutely require anti-piracy and content protection technologies. While DRM protection can be used by content owners to stop unlawful access to their material, forensic watermarking solutions are required to pinpoint the precise location of pirated broadcasts without degrading the viewer experience. In contrast to forensic watermarking, which is often tracked at each user who is consuming the content, distributor watermarking enables the content distribution end to trace each copy of the content being syndicated to the platforms. Distributor watermarking is used for the following reasons:
- To prevent piracy: Watermarking can help deter piracy by making it easier to trace the source of unauthorized copies of the content.
- To track usage: Watermarking can be used to track the use of the content, including how it is being shared and where it is being viewed. This can be useful for understanding the distribution and reach of the content, as well as for identifying any unauthorized use.
- To protect against tampering: Watermarking can help detect and prevent tampering with the content, such as by altering or deleting parts of it.
- To enforce licensing terms: Distributors can use watermarking to enforce licensing terms and ensure that the content is only used in accordance with the terms of the license.
- To prove content ownership: Distributors can use watermarking to prove their ownership easily.
PallyCon Distributor Watermarking
PallyCon Distributor Watermarking (DWM) is a watermarking solution that is imperceptible, robust to attacks and helps track illegally leaked video content. It can detect the watermark information from both the leaked video and a single video frame captured using any device, such as a smartphone camera. It inserts the channel information into the original video in the form of an invisible watermark. Additionally, it offers the choice of adding visible watermarks.
The CLI (Command Line Interface) tool used for the watermark embedding in PallyCon DWM comes in the following two versions:
- DWM PreEmbedder: Used to insert the distribution channel’s watermark into files in the Mezzanine or MP4 formats
- DWM DRM Embedder: Used when the dual protection of Multi-DRM + forensic watermark information needs to be added to MP4 video files streaming DASH/HLS format

The PreEmbedder will then create a separate version of the video for each channel, with a unique watermark added to each one. Finally, the corresponding DWM video should be delivered to each distribution channel, which may involve uploading the video to the channel’s website or platform, or providing a link for the video to be downloaded from a secure location.
In the event of a content leak, it is possible to use PallyCon’s detection service to identify the source of the leak. To do this, the leaked content should first be posted on a downloadable link and registered on the PallyCon Console. PallyCon’s service will then extract any watermark present in the leaked copy and use it to deliver the channel information (also known as the Distributor ID) to the customer. This information can be used to help identify the source of the leak and take appropriate action.

Thus, forensic video watermarking technology helps identify safe routes, allowing studios to penalize unreliable distributors while rewarding those with strong security. With the incorporation of an encoder, this can enable both secure live content and VoD as a cloud service. Video broadcasts can potentially contain undetectable watermarks that are particular to each subscriber. Therefore, content owners can identify the exact account that was the source of the leak and suspend it in the event that the asset is distributed illegally. In order to find the offending user or channel, the video can also be tracked back to the last approved recipient.
