Instead, if integrity has to be ensured, a fragile watermark would be applied.īoth steganography and digital watermarking employ steganographic techniques to embed data covertly in noisy signals. For marking media files with copyright information, a digital watermark has to be rather robust against modifications that can be applied to the carrier signal.
The needed properties of a digital watermark depend on the use case in which it is applied. Unlike metadata that is added to the carrier signal, a digital watermark does not change the size of the carrier signal. A signal may carry several different watermarks at the same time. Traditional watermarks may be applied to visible media (like images or video), whereas in digital watermarking, the signal may be audio, pictures, video, texts or 3D models. If a digital watermark distorts the carrier signal in a way that it becomes easily perceivable, it may be considered less effective depending on its purpose. Like traditional physical watermarks, digital watermarks are often only perceptible under certain conditions, e.g. It is prominently used for tracing copyright infringements and for banknote authentication. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. "Watermarking" is the process of hiding digital information in a carrier signal the hidden information should, but does not need to, contain a relation to the carrier signal. It is typically used to identify ownership of the copyright of such signal.
