Digital Watermarking
A digital watermark refers to various forms of tamper-resistant metadata that are primarily used to communicate with the owner of the data, to support intellectual property claims, and secondly to enforce processing instructions. Invisible watermarks, usually based on some form of encoding technology, can be applied to multimedia objects (bitmaps, audio, and video) and persist even when these objects are digitally processed.
