Forensic Watermarking is a technology to trace illegal content distributer by embedding purchasers’ information,
distribution channel, etc. into original content. If digital content was illegally copied or distributed online, content
provider or service provider can use forensic information to detect the first illegal distributor.

In terms of embedding mark into the original content, Forensic Watermarking is similar with the original
watermarking technology in technical part and yet different in functional part. The original watermarking
technology aims to embed and detect original content providers’ information whereas; Forensic Watermarking
technology can detect not only original content providers but also distributors. Therefore, to compare with
original watermarking technology, it could be a more highly utilizable technology.
