| Abstract: | A digital watermark embeds an imperceptible signal into data such as audio, video and images, for different purposes, including captioning and copyright control. First, the basic principle, importantpropertiesandthemainframeofdigitalwatermarksareintroduced. Then the digital watermark is classified into different types according to various aspects. Further more, various digital watermarking algorithms and its applications in different fields are analyzed. And the attacks on digital watermark are also simply introduced. Finally, the recent and future research in this field and the prospect of this technology are given. |
