digital watermarks
Hidden ownership stamps
Digital watermarks are hidden information embedded in media files—images, audio, video, or documents—to identify the source or prove ownership.
Unlike visible watermarks, digital watermarks are imperceptible to users but can be detected by specialized software.
They're used for copyright protection, tracking unauthorized distribution, and increasingly to identify AI-generated content: The studio embeds digital watermarks in screeners to trace leaks.
