The digital watermark technique is considered as an efficient and reliable approach to protect the high resolution remote sensing data. Firstly,the basic principles of digital watermark are introduced and the characteristics of watermark for high resolution remote sensing data are analyzed. Then,the applications of digital watermark in the security distribution management and web publishing of high resolution remote sensing data are studied and explored. Besides,the digital watermark system of high resolution remote sensing data is designed. Finally,the digital watermark technique of high resolution remote sensing data is looked forward.
