摘　　要：为了保护数字影像、音频和视频资料不被非授权者使用,数字水印技术在多媒体领域受到了密切关注。本文介绍了数字水印技术的发展现状,探讨了空域和频域水印技术在遥感影像版权保护及处理后的确认等方面的应用前景。In watermarking review of the application of protecting the technology has development of spatial digital image as well as video and audio data from non - authorized use, the digital played an increasingl watermark techniques y important role in the field of multimedia in recent years. A is given in this paper, followed by a discussion of the potential domain and transform domain watermark techniques in remote sensing images copyright protec- tion and verification in different forms of processed images.
