6 Types of Digital Watermark

 , updated on
A digital watermark is information that is embedded into media or data that uniquely identifies its source and ownership. This is used for a variety of purposes such as protecting copyright, tracking the source of data leaks and authenticating media. The following are common types of digital watermark.


At its most basic, a digital watermark is a logo or text that is embedded into media such as a photo.


More subtle watermarks can be embedded into an image such that they aren't visible. This can be done manually but is more often accomplished with algorithms that automated the process.


A watermark that disappears when the photo is processed. For example, with compression or resizing.


A watermark that survives a wide variety of transformations such as a photo filter or conversion to a different format.


Digital watermarks result in degradation of an image. In the case of a photo, this means that a photo no longer accurately reflects what was captured by the camera. Cyptographic methods can be used to embed a watermark in media that can be removed with proper authentication and authorization. For example, a password that restores a watermarked photo to its original data.

Data Watermark

Digital watermarks are often associated with photos and video. However, watermarks can be embedded into any type of data. For example, information embedded into a database by algorithms to prove its source or to track data leaks to a person. This typically needs to be reversible.
