Invisible watermarks

Definition

Invisible watermarks are hidden digital markers embedded within a digital file, such as an image or audio track, that can be used to identify the owner or creator of the content. These watermarks are designed to be undetectable to the average user, yet can be extracted or recognized by specialized software. This technology plays a crucial role in digital rights management by providing a method for tracking and protecting intellectual property.
