In the OTT industry, camcorder piracy has often been difficult to combat. Using forensic and visible video watermarking, it is possible to prevent DRM-protected content piracy via cam-recording. One can use watermarking to insert information into digital content that can be extracted even if the file has undergone encoding changes.

To be more precise, a “forensic watermark,” also called a “virtual watermark,” is a code or a set of characters embedded into a digital document that reveals the owner or creator of the content. It may also include the user’s identity information, as is the case with DRM protected content. There are many reasons for this, but one is that watermarks are completely undetectable to the naked eye. It is possible that a viewer’s enjoyment of the video will be diminished if there is any distortion.

A forensic watermark’s ability to carry a payload is an important consideration. For video watermarking to work, encoded video assets must be able to contain information about the content owner, IP addresses of server and client devices, session information, etc. in each frame of the encoded video.

Additionally, the payload must be robust because a watermarked piece of content travels through a lengthy distribution chain before it reaches the pirate servers. There are four stages to this procedure: Encoding the video, identifying each frame of the encoded content, streaming the encoded content, and capturing and monitoring leaked content. Finally extracting the identifiers from each frame.

The quality of the video output can be harmed by a loud visible watermark, on the other hand. Visual watermarking may have greater value outside the OTT space, such as in digital library, e-commerce platform, and print media files. Since the copyright information is clearly visible to everyone, it discourages the practise of copying.
