摘要：Digital Watermarking is a technique which is used for concealing the information in any document for its copyright protection. The purpose of digital watermarking is to embed information imperceptibly and robustly in the host media. Confidential information of owner that is inserted into host media is known as watermark. The digital watermark may be used to verify the authenticity or integrity of the signal or to show the identity of its owners. In this paper, its objectives, characteristics, types and various techniques that are implemented for copy control are introduced. Various types of attacks and different fields where digital watermarking is applied are also discussed in this paper.
