Explanation

Watermarking is a technique of hiding a signature or a message into a digital media, such as an image, a video, or an audio, in a way that is imperceptible to the human eye or ear, but can be detected by a special software or device. Watermarking can be used for various purposes, such as authentication, integrity, ownership, or tracking. In this case, the Internet media company can use watermarking to track the distribution of its content and identify the sources of piracy. The company can embed a unique watermark into each copy of its content that is distributed to its customers or partners, and then use a watermark detector to scan the pirated copies and trace them back to the original recipients. This can help the company to enforce its intellectual property rights and prevent further revenue loss. Installing the latest data loss prevention (DLP) software at every server used to distribute content may not be effective, as the content can still be copied or captured by the end users or intermediaries. Logging user access to servers and auditing them every day may not be feasible, as the volume of data and the number of servers may be too large to handle. Hiring several investigators to identify sources of pirated content and report people sharing the content may not be efficient, as the investigators may not have the access or the authority to monitor the online activities of the potential pirates.
