Seminar Topic: Watermarking

Introduction:

Digital watermarking is the process of embedding information into a digital signal in a way that is difficult to remove. The term is derived from a process used since 1282 in the production of paper bearing awatermark for visible identification. In digital watermarking, the signal may be audio, pictures, or video. If the signal is copied, then the information also is carried in the copy. A signal may carry several different watermarks at the same time.
