Watermarking is the process of embedding a hidden marker or code within digital content, such as images, videos, or documents. This marker is typically invisible to users but can be detected by specialized tools. Watermarks serve various purposes, including proving ownership, tracing the origin of content, or indicating that a file has been artificially generated or altered. In cybersecurity, watermarking helps protect intellectual property, deter unauthorized use, and ensure the authenticity of digital assets.
