Forensic watermarking is intended to provide a means to identify the source of leaked content at the distributor level, at the more granular device level or even the session/subscriber level. When leaked content is found on piracy sites, it can be analyzed for any embedded marks which, when extracted, can provide chain of custody through to device/subscriber identification depending on the marks present. This information can then be employed by investigative teams to locate the leak source and act to stop future piracy. Imperceptible watermark should be used as best practice.
