Forensic Watermark is best described as which option?

• A. Digital Rights Management
• B. Watermarking
• C. Forensic Watermark
• D. Deep Packet Inspection

Answer: (C)

Forensic watermarking is the practice of embedding unique, imperceptible markers into digital content so that each copy can be traced back to its source. This is designed for post-distribution tracing, even if the content is re-encoded or redistributed. The option that matches this concept best is the term itself: Forensic Watermark. It differs from Digital Rights Management, which focuses on controlling access and use rather than identifying a leak. It also extends beyond generic watermarking, which is a broader idea of embedding marks without the forensic tracing capability. Deep Packet Inspection concerns analyzing network traffic, not embedding watermarks into media. So, the best answer is Forensic Watermark.
